How to fill the CV joint with grease without removing the anther. What is the best way to lubricate the joints? Disassembly of the node and its lubrication

- an integral element of the suspension of any front-wheel drive car.

He is a guarantor of uniform rectilinear movement, the service life of which is comparable to the service life of the car itself, however, only in the case when it is constantly competently cared for - diagnostics are carried out, timely replacement of mounting clamps, rubber boot and, of course, lubrication. Diagnostics of the assembly and replacement of its constituent elements are simple procedures, even a beginner can handle them, but the question of which lubricant is best for a CV joint can confuse even experienced motorists, because lubricants, like hinges, are different. How not to get confused in all this diversity and make the right choice, our article will tell.

It's no secret that manufacturers decided to lubricate some car parts with special technical fluids for a reason. There were reasons for this - tasks / problems that this liquid could minimize or solve. In the hinge of equal angular speeds, such bases are:

• preventing the occurrence and prevention of the spread of corrosion - in metal elements, it leads to the appearance of cavities, called shells in CV joints, which significantly reduce the efficiency of the transmission and create an audible knock when the steering wheel is turned;
• reducing the coefficient of friction, ensuring free rotation of the elements and, as a result, minimizing the load on the front axle transmission;
• reduction of energy losses during the transmission of force (less energy losses - less fuel costs);
• safety in relation to synthetic and organic polymers, because plastic or rubber boots are always used to protect the swivel from dust and dirt, so the lubricant used in this connection should not corrode them.

Not every lubricant is capable of solving all these problems at the same time, so we will immediately exclude all unnecessary and leave only those options that meet this requirement.

Varieties of lubricants for CV joints.

1. Lithium (Renolit, Hado, Litol-24, Very Lube).

The most popular lubricant among car owners. It looks like a viscous thick yellow consistency, thickening strongly at low temperatures (the grease becomes so dense that it is practically impossible to spread).

Advantages:

• compatible with virtually any type of polymer used to protect constant velocity joints;

Flaws:

• poor corrosion resistance, therefore, components treated with lithium greases should be checked at least every 50-60 thousand kilometers (with the exception of Litol-24, its manufacturers guarantee 100 thousand kilometers of uninterrupted operation);
• incompatibility with modern high-strength plastics, especially Litola-24, so if it is they who protect the SHRUS in your car, be sure to read the operating instructions before using this or that lubricant, you will find recommendations in it, what is the best lubricant for CV joints in your particular case.

2. Lubricants based on molybdenum disulfide (Mobil, Liqui Moly, BP, SHRUS-4, ESSO, Texaco).

A modern analogue of lithium compounds. It looks like a thick ointment of brown, gray or black.

• copes well with friction, no worse than lithium greases;
• has a high resistance to corrosion, however, to maintain this advantage, it must be changed every 100 thousand km. run.

• the composition is very afraid of moisture and when it encounters it loses all its useful properties, therefore, the efficiency of lubricants based on molybdenum disulfide is guaranteed only in cases of a whole anther, therefore, when using them, the tightness of the rubber / plastic protection should be checked at least once a month, and also after every off-road driving and strong impacts to the front of the bottom of the car.

3. Barium lubricants.

They have been specially designed for use in vehicle constant velocity joints.

Outwardly, they are a long-fiber brown or yellow ointment, endowed at the same time with the advantages of lubricants based on molybdenum disulfide and lithium soap:

• copes well with friction, reduces the load on the components of the drive mechanism by several tens of times;
• compatible with any polymers and plastics;
• neutralizes dust and dirt that accidentally got inside the anther;
• practically impervious to moisture.

There are only two disadvantages:

• high price;
• fear of negative temperatures, due to which the manufacturer recommends replacing the composition on the hinge after each winter.

What lubricant to choose?

Each of the types of CV joint grease just presented has an equal chance of being called the best, it all depends on what criterion this title is awarded, so the final choice is, as always, only for you: if you want to save as much as possible, choose lithium compounds , just before carefully read the operation manual of your vehicle for the possibility of their use; if you want, as they say, to smear and forget, then your choice should fall on barium compounds; in all other cases, use a molybdenum disulphide lubricant, just remember to check the condition of the anther.

What lubricants should not be used?

Whatever persuasive specialty store salespeople tell you, never use for CV joints:

• calcium / sodium based greases - they are not suitable for lubricating highly loaded units, deviation from this recommendation is fraught with accelerated corrosion and reduced hinge life up to 15-30 thousand km;
• graphite grease - it is not thermally stable, therefore, when used in CV joints, it reduces their service life to 20-25 thousand km;
• hydrocarbon compounds (including technical petroleum jelly) - again, due to instability to high temperatures, they are completely washed out of the assembly after a few kilometers, which means that the CV joint will work dry, and the longer this happens, the faster the part will need to be replaced;
• mineral lubricants based on iron / zinc - do not withstand increased loads and, like the previous compounds from this list, contribute to accelerated wear of the constant velocity joint.

What is the best lubricant for CV joints and why is it needed? Front-wheel drive cars have a number of advantages over rear-wheel drive cars. Front-wheel drive vehicles are easier to manufacture and more resistant to skidding on wet and snowy road surfaces. But besides the advantages, these cars also have disadvantages, these include the use of a hinge of equal angular velocity in the drive of the car, which ensures confident movement.

The CV joint is a part that contributes to the rapid wear of the transmission. To extend the life, it is necessary to use a specialized lubricant for the outer and inner CV joint, which increases its wear resistance and transmission components. Today, a huge number of different lubricants and car owners have to rack their brains over the question of which lubricant option will best lubricate the CV joints and their hinges before they choose the right one.

What is the function of a lubricant?

Motorists know that lubricants used in car joints and joints not only reduce friction and prevent premature wear of machine parts. But they also reduce the load on the parts, as a result of which the parts rotate freely and the car continues to move without friction and load.

SHRUS lubrication allows you to reduce fuel costs and transmission losses. An important property is the prevention of the spread of corrosion. It is during corrosion that the work of CV joints is accompanied by the appearance of an unpleasant knock, which intensifies when the steering wheel is turned and the torque is not transmitted efficiently. So that the CV joints do not get dirty, anthers are used. It is important to prevent grease from getting on the anthers, they are made of rubber or plastic, which eats through when in contact with the grease.

When does the SHRUS grease change?

Lubricant is replaced in the following cases:

• torn anther and its replacement;
• replacement of the angular velocity control hinge;
• CV joint operation for more than 5 years;
• run over 100 thousand kilometers.

Do not apply a large amount of lubricant, this will not give better protection, but only increase the likelihood of spoiling the anthers. There should be enough lubricant so that the part is completely lubricated and no grease drips from it.

How much grease to fill in the CV joint? It all depends on whether it is internal or external. For the inner CV joint, 100-110 grams is enough, and for the outer 70-80 grams.

Varieties of lubricants

Along with the question: which CV joint is better, motorists are faced with the problem of choosing a lubricant. There are many different lubricants for CV joint care, and each has its own advantages and disadvantages. Here we consider only those that have proven themselves and are considered the most suitable.

Lithium-based lubricants

The most common lubricants are lithium foam based in organic acid. These greases are yellowish in color and slightly thick. In the cold, they thicken even more, as a result of which their spreading on the part becomes a little problematic. This problem makes itself felt at a negative temperature at the beginning of the ride - you can hear the tapping of the CV joints and suspension. When all the mechanisms warm up, the car is getting better. Such lubricants well reduce friction and reduce the load on the nodes up to 10 times.

The big advantage is the neutralization of trapped dust and the ability to keep moisture out of parts. Another feature of lithium greases is that they are fully compatible with polymers that are installed on CV joints, with the exception of some hard plastics that are present on modern cars.

The disadvantage of lithium greases is that most of them do not resist corrosion well. This is what you need to pay attention to first of all when choosing this type of lubricant.

Lithium-based lubricants such as Litol-24, Renolit, Hado can be used. These lubricants have already proven themselves on the market and are distinguished by the most suitable properties.

Lubricants based on molybdenum disulphide

Due to the fact that the lithium version is not suitable for all cars, the engineers had to look for a way out. The solution to the problem was a lubricant in which molybdenum disulfide is added. Thanks to this compound, the CV joint lubricant has acquired high anti-corrosion resistance. In addition, the amount of acid in the lubricant is reduced, which reduces the level of interaction with solid polymers. Thanks to this, it became possible to use such a lubricant on any modern car.

If we consider resistance to friction, then in this feature lubricants based on lithium and molybdenum disulfide are almost the same. But still, there is a big drawback in the molybdenum disulfide product. The grease completely loses its properties after water gets under the damaged anther. To prevent this from happening, you need to inspect the condition of the anthers at least once a month. You should also look under the car after strong blows to the suspension and off-road trips.

Such lubricants are produced by a variety of manufacturers. SHRUS-4 grease, domestically produced, is not inferior to analogues from other countries, it works no worse. From foreign, you can use lubricants such as Mobil, BP, Liqui Moly, Esso.

Barium based lubricants

Recently, scientists have created many different lubricants for CV joints, but only one type combines the advantages of lithium and molybdenum without their disadvantages - barium lubricants. The main advantage of such lubricants is their high resistance to moisture. For example, if the boot ruptures, then the barium-based lubricant can not be changed until a lot of dirt has accumulated in it.

No less important is that such a barium grease protects the CV joints from all types of corrosion and does not dissolve the anthers from any polymers. The only thing that this type of lubricant cannot boast of is the price and low resistance to negative temperatures. Barium-based greases are much more expensive than lithium and molybdenum greases due to the complexity of their manufacture and are much less common.

There is only one domestically produced barium-based product on the market - ShRB-4.

What lubricants should not be used

Under no circumstances should greases based on the following be used:

• graphite (serve to protect bearings);
• hydrocarbon;
• zinc;
• calcium;
• sodium;
• iron based.

They simply lead to the destruction of the mechanism.

How to choose a lubricant

Lubricating SHRUS lubricants have a different appearance. Given all the features and internal set of characteristics of lubricants, the most suitable option today is lubricants based on molybdenum disulfide. A good option, suitable for all vehicles, minimizing friction in the joints and resistant to corrosion, with minimal impact on the boot. By lubricating each CV joint assembly, you will extend its life. But still, when choosing a lubricant, you should follow the recommendations in the instructions for your car.

The abbreviation SHRUS is an abbreviation of the phrase "constant velocity joint". In the cardan shafts of rear-wheel drive vehicles, similar functions are performed by hinges consisting of a cross and cups with needle bearings. The only difference between them is that the crosspiece provides a much smaller degree of freedom than the CV joint. But the cheapest CV joint is much more expensive than the most expensive cross. This circumstance increases the desire to extend its service life. For which, of course, you can use a good lubricant and monitor the condition of the anther. Therefore, the question of what is the best lubricant for CV joints is logical. Timely replacement of a torn anther will also extend the life of the grenade if the lubricant is changed at the same time.

SHRUS design

At the beginning of the last century, many CV joint designs were developed, which are used to this day. For example, crackers or cam, cam-disk, ball with dividing grooves or dividing levers, with spherical rollers and a fork, twin cardan shafts. All CV joints have both advantages and disadvantages. The characteristics of each design are better for some conditions and not so good for others. Therefore, there is no question which design is more successful.

For the outer joints of the drives of modern fast passenger cars, the performance of a ball joint with 6 balls has proven to be better. The same number of grooves for them has the body of the CV joint and the inner ring under the separator, which keeps the balls from falling out of the CV joint. The connection of the inner ring with the drive and the CV joint housing with the hub is splined. At large angles of rotation of the drive wheels, the maximum allowable torque transmitted by the hinge is much less than at small ones. Therefore, for long-term trouble-free operation of the CV joint, it is necessary to prevent its operation with a large load in the extreme positions of the steering wheel. Each CV joint is necessarily protected by anther.

Tripoids are often used as internal grenades. They are less mobile, but more wear-resistant, as they use needle bearings in their design.

Lubricant composition for SHRUS

For modern ball joint joints, lithium grease is used, most often based on mineral oils containing molybdenum disulfide as an antifriction additive (from 3 to 5%). Due to the black color, it can be confused with graphite grease, which should never be used in cv joints. Ordinary lithol, due to its weak anti-friction qualities, cannot be lubricated with CV joints either.

For tripoids, the lubricant described above cannot be used. Only a special barium-based lubricant can be used for them. One of its differences is the wide temperature range in which it can operate. After all, in winter the drive cools down to -30, and in summer it heats up to +160 ○ C.

Greases are made by thickening the base oil with various thickeners, which can be used as salts of higher carboxylic acids: lithium, calcium, aluminum, sodium and others. Inorganic thickeners such as bentonite clay can also be used, as well as synthetic ones such as polytetrafluoroethylene. As a rule, the composition of the lubricant includes up to 90% of the base oil, the remaining 10% is the share of the thickener and various additives that determine the main characteristics of the substance.

In what cases does the SHRUS lubricant change?

If the drive has crackled, it is too late to change the lubricant in it. You need to change the drive itself. This is explained by the fact that if the hinge crunched, it means that it already has a significant output and no matter how much you change the lubricant in it, it will not get better from this. To determine which of the hinges crunched, you need to select a flat asphalt area and drive along it, turning the steering wheel all the way to the left, and then all the way to the right. At this time, the assistant, being outside the car, should evaluate in which case the crunch is louder. If the sound is louder when the steering wheel is turned to the left, then the left outer drive needs to be changed. When the crunch is louder with the wheels turned to the right, you need to change the right external drive.

How to change the lubricant in the cv joints

Proper lubricant change. The replacement of the lubricant in the cv joints is done due to its contamination after the anther has ruptured or has run out of a resource when it contains a lot of wear products. It is necessary to remove the old grease from the hinge completely to eliminate the possibility of increased wear on the CV joint. To do this, it should be disassembled and thoroughly wiped with a clean rag. It will not work to rinse it without disassembling it, because the grease is extremely poorly washed off.

Retaining ring

With disassembly of the internal hinge, there are usually no difficulties, so we will describe the disassembly of the outer one. If you do not have a special tool for removing the outer joint, then remove the drive assembly and clamp it in a yew. Remove the clamps from the boot. When removing, try not to damage them, factory ones are usually better than those that come with a new boot. If the boot is torn, cut it off with a knife; if not, slide it onto the actuator stem. With a hammer blow through the drift on the inner ring, knock the hinge off the drive. Turn the inner ring with the separator so that the holes in the separator are visible, while the symmetry axes of the separator and the body will be perpendicular. Using a flathead screwdriver, remove all balls from the cage. In the separator, two of the six holes are longer than the others. Turn the cage so that they are pressed against the walls of the housing and remove the cage with the inner ring from the housing. Having picked up the position of the inner ring, remove it from the cage. As best as possible, remove the remaining grease from the parts, and you can assemble the hinge.

Insert the inner ring into the cage. Orient the cage so that the long holes in it are pressed against the hinge body, and insert the cage with the ring inside the body. Insert the balls into the cage holes and rotate the inner ring so that the drive hole is located along the body axis. The assembly takes from 120 to 150 g of lubricant. How much will fit in your case depends on the size of the hinge.

To correctly fill the joint with grease, clamp it in a yew with the drive hole up. If you bought the lubricant for it in tubes, then press it into the hole for the drive, pressing the tube more tightly against the ring, until it appears between the separator and the housing. If you have it in a different package, then put it on with a spoon and push it into the drive hole with a cylindrical object of a suitable diameter; the entry criteria is the same.

When installing the boot, do not stuff a lot of grease into it, otherwise it will break it during operation of the boot. Before tightening the boot clamps, grease the grooves for them with lithol.

Lubricant testing

The tests included the following checks:

1. Flushing with water and protecting the site from penetration of this liquid into it.
2. Fluidity when the temperature rises up to 180 ○ C.
3. Lubricating properties.
4. Lubricating film resistance to pressure.
5. Wear of metals protected by grease.

Places during the testing process were not distributed to the contestants, they simply gave marks, so you will have to determine which lubricant is better. Below are the results of testing ball joint greases by an independent researcher.

Correctly lubricate the tripoid joint

Despite the fact that the design of the tripod joint is based on the use of needle bearings, it is strictly forbidden to lubricate them with grease, which is usually used for needle bearings. The fact is that a lithium thickener is used for its manufacture, and it can work at a temperature not higher than 120 ○ C, and the temperature of the inner grenade reaches 160 ○ C. Since the lubricant for the inner grenade is quite liquid, it is better to pour it inside the anther installed on drive, and then assemble the tripoid. You need to fill in from 100 to 130 g of lubricant. More precisely, the question, "how much?" manufacturer will answer.

Most motorists do not fully know the names of the parts that make up the car. Therefore, when abbreviations are spoken in repair shops, sometimes difficulties arise. Such details with an intricate name include CV joints - hinges of equal angular velocities. This detail requires more attention. In particular, it is necessary to control the CV joint, the lubrication of which is extremely necessary and has a significant impact on the proper operation of the car.

The main purpose of this part is the transfer of rotational movements from one axle to another. The hinge was invented a long time ago and is now an indispensable component of every modern car. The hinge is quite simple in design. If properly cared for, this item will last a long time. This device consists of four parts:

There are two types of this device: external and internal. These types of devices have different characteristics. In terms of dimensions, the internal hinge is larger, and therefore its price is more expensive. As for the external hinge, its main tasks are to rotate the wheel hub.

How to choose a lubricant for a CV joint

In order for the device to work like a clock, it requires maximum care. The main care for the hinge is its lubrication. Very often, many people ask this question, what kind of lubricant to use for the CV joint? To do this, you do not have to be an auto mechanic, you just need to know which lubricant is used for the inner CV joint, and which for the outer.

Modern lubricants are made from recycled petroleum. The use of lubricants is necessary for certain purposes, namely:

• To reduce the force of friction between parts.
• To improve the wear resistance of the surface of parts.
• To reduce stress on parts.
• To provide protection against metal pests such as corrosion and aging.

Each part that is included in the design of this device has its own care features. Before using lubricant, it is better to familiarize yourself with the technical characteristics of the devices.

So, I will acquaint you with the rules for caring for this device. It is believed that the duration of the functioning of these devices is directly related to the means used by auto mechanics. The choice of lubricant must be taken seriously. Given the importance of this device, a special lubricant mixture has been developed that is designed for these mechanisms.

Many auto shops provide inner CV joint lubricant to customers. This substance is presented in solid or semi-solid packaging - this is CV joint lubricant 4. The lubricant CV joint 4 has features that significantly distinguish it from similar elements existing on the market. The tool has increased strength, which allows it to stay on the parts that are in constant motion. This mixture is quite viscous, which indicates the unusual composition of this element.

The viscous consistency allows this substance not to turn into a liquid in any weather, at any time of the year. The composition of the lubricating mass for hinges contains such microelements that help prevent the occurrence of corrosive deposits, and also prevent metal aging. Also, this mixture for hinges has a fairly good water-repellent effect, which is good news, especially in wet weather. One package of this substance is enough for long-term use.

How often to change the lubricant?

Almost every car owner at least once faced with the question “how often is the lubricant in the cv joints replaced”. The answer will not be long in coming and will be such that the CV joint 4 lubricant must be changed constantly in such situations: if a new constant velocity joint is being installed, and also when the boot is being replaced.
It is also relevant to replace the lubricant when the car's mileage reaches more than 100 thousand kilometers, given that this was the last lubricant change.

For longer operation of the device, it must be abundantly lubricated. The amount of mixture required for application is always indicated in the technical data.

As the proverb says: "If you don't anoint, you won't go." This rule also applies to automotive parts. For motorists, the modern market offers a huge selection of lubricants for the inner joint, it is important to remember that you cannot save on this substance, because. this can subsequently render parts of the vehicle unusable. The price of a mixture of CV joints 4 corresponds to its quality. The tool is quite popular in use. Many car owners, as well as service stations, give their preference to his preference.

Also, one should not forget that it is necessary to lay the lubricant on the recommendation of specialists; an excessive amount of the mixture is not rational. If there are doubts about how much lubricant to fill in the CV joint, then it is better to turn to specialists for help, so that they prompt and advise.

The choice of lubricant for the internal hinge is always a very important decision, so you should remember that before buying it is better to familiarize yourself with all the technical characteristics so as not to harm the device.

Video “Replacement of SHRUS grease”

The recording shows how to quickly and easily change the CV joint grease.

One of the key mechanisms of the car is the constant velocity joint (CV joint). This part is quite reliable, however, due to the cyclic rotational load, it requires timely maintenance.

What is SHRUS grease for?

The use of lubricant solves a number of vital tasks for a car:

• Friction reduction;
• Prevents premature wear of parts;
• Reducing the overall load on the part;
• Reduced fuel consumption for transmission loss;
• Corrosion prevention;

With untimely maintenance, the transmission of torque decreases, an unpleasant knock appears when the steering wheel is turned.

Types of lubricants

Over time, more and more different lubricants appear on the market. They differ in their composition and properties. According to the composition of the lubricant are divided into two main categories:

1. lithium;
2. Based on molybdenum disulfide.

Lithium greases

Lithium greases for CV joints are the most common and affordable option. Photo: a.d-cd.net

The most common type of lubricant for transmission maintenance. The substances have a yellowish substance with excellent viscosity, which thickens at low temperatures.

Lithium compositions are characterized by high conservation properties, which have a pronounced anti-corrosion effect. This lubricant does a good job with dust and dirt entering the mechanism, but does not solve this problem as a whole. The drive system should be serviced every 40-50 thousand mileage.

Most lithium greases are neutral to polymeric materials from which modern anthers for CV joints are made.

Important: high-strength organic-based plastic can be dissolved by lithium compounds.

In such cases, you should look into the operating instructions, which should contain recommendations for servicing the CV joint and the compositions used for lubrication.

• Widespread, due to low cost and sufficiently high efficiency;

• React with polymeric materials;

The following products are widely available on the market:

• RENOLIT;
• XADO;
• Very Lube;
• Litol-24.

Compositions based on molybdenum disulfide

The specialists were faced with the task of extending the anti-corrosion protection of parts and reducing the likelihood of anthers reacting with polymeric materials. The problem was partially solved by using molybdenum sulfide.

The use of compounds based on molybdenum disulfide has become a new step in the automotive industry. Photo: Forum.rcdesign.ru

• Increasing the resistance of parts to corrosion is the main feature of compositions based on molybdenum sulfide. The specialists who conducted the comprehensive tests indicated in their reports that after a run of 100,000, there are no signs of wear on the mechanisms.
• Partial substitution of metal salt for organic acids made it possible to reduce the reaction with polymers. As a result, manufacturers recommend the use of this lubricant composition in almost all modern cars.

• If moisture gets inside the CV joint, it can completely lose its properties, which in turn leads to the failure of the entire assembly.

IMPORTANT: you should carefully monitor the tightness of the anther so that the grease does not come into contact with water.

With all the advantages of the composition of this group, replacement is still necessary every 95-100 thousand mileage.

The market offers a wide range of products that differ both in quality and price. The following compounds are most often used:

• Liqui Moly;
• Texaco;
• Moby;
• ESSO;
• SHRUS-4.

barium lubricants

Most of the new tools are either weakly effective or too expensive to manufacture.

An example of an alternative lubricant is barium, or rather compositions based on it.

• Neutrality in reaction with moisture. If the tightness of the anther is damaged, there is no need to change the lubricant. Operation can continue until dirt and dust enter the CV joint.
• Neutrality in reaction with polymers. Can be used with anthers made of any polymeric material.
• Reliable protection against corrosion in extreme operating conditions (off-road, sand, etc.).

• High price. Especially for well-known foreign manufacturers.
• Low frost resistance. When operating in cold climates, it requires frequent periodic replacement.

Replacing the grease in the CV joint

There are several stages in the replacement process:

1. Disassembly of the chassis of the car.

We remove all elements holding the CV joint (ball rods, bearings). The mechanism is removed carefully to exclude the possibility of damage.

Apply notches on the CV joint housing and support, which will serve as guidelines for precise assembly (it remains just to combine them).

1. Dismantling the CV joint directly and removing the old composition. Separate the outer and inner parts. Clean parts from old grease and dirt. It is enough to wipe with a thick cloth or paper.

IMPORTANT: Do not use car shampoo or soap, residues of which may impair the quality of the lubricant. There are special cleaners.

1. Filling the CV joint with new grease. The outer part is filled to the limit, it is better if the lubricant protrudes. The inside should be three-quarters full.
2. SHRUS assembly.
3. Installation in a regular place, installation of anthers. A small amount of lubricant should be placed inside the boot and distributed evenly over the inner surface.
4. Assembling the running gear of the car.

It should be noted that automakers and experts recommend that maintenance work be carried out on the CV joint at least a run of 60 thousand kilometers. Lubricant manufacturers convince the buyer of the quality of their product and recommend replacement every 80-90 thousand kilometers. With active operation in difficult conditions, the chassis should be checked every 40 thousand mileage. Conversely, if the car rarely leaves the garage, then replacement can be done at intervals of 4-5 years.

Important features and summary

When solving such an important task, it is worth performing several sequential actions:

• Read the vehicle's instruction manual. In this useful book you can find all the recommendations of specialists in the maintenance of all components and assemblies.
• Determine the properties of the materials from which the CV joint is made.
• Determine the frequency of replacement of lubricants depending on the operating loads of the vehicle.
• It is worth calculating the funds that will be spent on the purchase of lubricants.

When buying a lubricant, you should pay attention to the components contained in it. In addition to the above, there are also substances based on graphite, minerals, zinc, iron, etc. These products are mainly used to lubricate various types of bearings in other units and assemblies.

Summing up, it can be noted that the most optimal in terms of price-quality ratio are lubricants based on molybdenum sulfide. They have a number of advantages over other competitors and, subject to the tightness of the anther, provide reliable protection for the CV joint.
