If they creak when moving ball joints, this is often caused by a lack or lack of lubrication under the boot of this swivel joint. This is due to rupture of the anther. In rare cases, an insufficient amount of lubricant is applied in production. In order for ball joints and steering tips to run their entire resource, they must be serviced. Novice car owners often do not know how to maintain the chassis and what kind of ball joint lubricant is needed. Today we will try to answer this question.

Do ball joints and steering tips need to be lubricated?

There is an opinion that it was necessary to process these connections earlier at the time classic models VAZs, "Muscovites" and other automobile industry from the USSR, but now it is not necessary to do this. To find out if these parts need service, you need to understand how the ball valves work.

The device can be different. But in the design there is always a ball joint and a finger. The base is used as a hinge stop. From above, the support is covered with an anther.

During operation, the hinge is constantly shifting and moving. This contributes to its accelerated wear. During operation, the lubricant is produced. And if the car is standing for a long time, then the lubricant product may dry out. In addition, if there is no lubricant for the ball joints in the space between the base of the unit and the boot, then dirt will form there. It not only accelerates wear but also causes poor joint performance. If knocks and creaks appear in the ball, this is an alarm bell.

In order not to subject the ball joint mechanism to accelerated wear, it is necessary to clog lubricant into the free space under the boot. But you also need to know what kind of lubricant to use for ball joints so that these units work as long as possible.

When do you need to machine ball joints and head ends?

The ball joint is lubricated at the factory before being installed on the vehicle. But if we are talking about domestic cars, then this requirement is not always fulfilled. In addition, during the operation of the vehicle, the hinge is constantly displaced. Accordingly, the lubricant is constantly consumed. Therefore, it is necessary to process the node constantly, at regular intervals. But how do you know if you need new ball grease?

All problems associated with ball joints, even in the early stages, can be easily identified "by ear". But for serious problems, modern diagnostics can help. The first signal that indicates that the lubricant has developed is squeaks and knocks during the movement of the car. If these sounds come from the places where the ball joints are installed, then these nodes are checked first. If there is no serious play in the hinge, then regular maintenance of the element will help to extend the life of the element.

Signs of a ball joint failure

The fact that grease for the ball joints has developed can be recognized by knocking when driving over irregularities. Also, if you need to lubricate the steering tips, you can hear the wheels.

He may talk about the need to change the lubricant in the ball. If the car does not keep a straight trajectory and the wheels are constantly wobbling, this also indicates worn ball balls. Also, rubber, which wears out unevenly, indicates breakage or wear.

How to lubricate?

And now, a novice car owner hears characteristic squeaks and realizes that it is time to service the ball and steering tips. But since beginners do not have much experience, they are worried about what kind of lubricant is needed for ball joints and steering ends.

Let's try to answer this question. Often, lithium-based lubricants are used for such. These compounds withstand well the high loads that the hinge experiences during operation. You also need to be able to choose the right product.

What is special

By their composition, lithium-based materials are substances derived from petroleum oils. During the manufacturing process, oils are thickened by the addition of lithium soap. This makes it possible to obtain the desired consistency. At the same time, petroleum oils in combination with fatty acids contained in lithium soap also have an additional preservative effect. Car owners in practice use several types of lubricants on this basis. They differ among themselves in the percentage of oil and lithium soap, as well as in the content of various additives. Well, let's consider them in more detail.

"Litol-24"

It is the most common ball joint and steering grease among car owners. And there are several reasons for this. The first reason is that this lubricant works better. temperature range, which makes it possible to use "Litol" in any climatic zones.

Due to the presence of stabilizing additives, this lubricant can serve for a rather long period of time. The composition reliably protects metal rubbing parts from negative destructive effects. It is also necessary to cancel that "Litol" is not afraid of temperature extremes. Do not worry that when driving on water or snow, a ball lubricated with Litol will lose its protection.

"Tsiatim-201"

If "Litol-24" is a very popular product, then "Tsiatim" is used for ball joints much less often. If we compare it with the previous one, then the threshold for operating temperatures is significantly lower. This grease will not freeze even at temperatures as low as -60 degrees. Therefore, this product is widely used in the Far North.

Although this grease differs in lower characteristics in comparison with "Litol", its stability at low temperatures is its plus. Also "Tsiatim-201" has a lower price.

Alternative options

In addition to lithium-based greases, which are classic, other types of calcium-based ones are used. The main disadvantage of these lubricants is that they are afraid of low temperatures. Moreover, their service life is much longer. Experts say calcium greases have more high level protection of metal parts from corrosion. But in practice it is believed that best lubricant for a ball joint it is definitely a lithium product.

What to choose?

The stores now offer a lot of lubricants for lubricating ball and steering ends, but you should not purchase branded expensive products. By technical specifications they are not much different from more affordable counterparts. Therefore, you can choose the most ordinary "Litol-24", and this will be the right decision. But you need to look at the composition.

Calcium materials will always be more expensive. Therefore, if you choose them, you will have to pay a little more. When choosing a lubricant, it is advisable to pay attention to the conditions in which the car is operated. If the car drives in extreme temperatures, it is best to choose a product that can work in such conditions. This will help reduce wear on parts during winter operation. Otherwise, there are no peculiarities when choosing. There is not much difference in what kind of lubricant should be in the ball joints. The main thing is that she was there, motorists say.

Nylon instead of grease

The first ball joints were hinges with a semicircular bearing part. Then this design was abandoned, and the tip of the finger was made in the form of a ball. This is an all-metal knot. Sealing was carried out using a special spring support. To make the part moveable, it was filled with grease.

Advances in equipment allow the body and pin to be produced with high precision, and instead of a plastic liner, a special nylon is used. It allowed the hinge to retain its properties and characteristics without the need for lubrication.

The lubricant with which the support is filled at the factory has special composition and differs from the one sold in stores. Engineers argue that there is no particular benefit from such lubrication, and they tried to say about this back in Soviet times. But in our country they don't trust plastic too much. Therefore, novice car owners will be interested in what kind of lubricant is best for ball joints for a long time.

Lubrication of the ball joints consists in wiping the grease nipple, installing the syringe (if necessary, you can "(" use the adapter) and carefully squeezing the grease into the support. Now you will see how to do it correctly.

1. Understand how many lubrication points your machine has and where they are located. See the previous section “Finding Lube Points”.

2. Wipe off the first grease nipple and try to put a syringe on it. Happened? If not, then you need an adapter. Do you have it? If not, then you need a dilator.

3.Fill the syringe with grease.

To do this, you will need the lubricant used for the suspension.

4. Move the syringe towards the oiler and gently squeeze out some grease (5).

Never fill up the legs with grease. The amount of grease can be checked by squeezing the ball cover. It doesn't have to be tight. When the boot is firm and full, squeeze a little grease outward if there is a hole in this type of support. But if this support is of a sealed type, then you need to fill the cover completely. If the cover looks full, do not add any lubricant there and move on to the next support.

5. Repeat steps. 2 and 4 until you service all the supports.

6. If you overdid the sealed bearing, use a suitable socket wrench to unscrew the grease fitting (counterclockwise). Squeeze out some grease and screw the grease nipple back on.

Dealing with a retouched hinge - V is not the most pleasant experience; be careful and squeeze out the grease in small portions. I know because I've had to deal with it. How difficult it is to deal with this slippery little grease nipple.

7.If one of the covers bursts, it must be replaced immediately.

The parts that protect the covers are very important, so if you don't change them, after a short ride on a non-functioning support, you will have to pay a lot of money for repairs (or even complete loss of control of the car).

When buying a new car, ask your service manager. does this model have weak points where it would be nice to put an additional grease nipple. I had a couple extra on my car

installed, it is convenient and inexpensive. If you constantly hear a creak while driving, ask if it will disappear if you install a grease fitting in that place.

Technologically it is provided so that the suspension includes a steering gear, but it seems to me that, guided by their functional purpose, it is better to separate the two systems. Therefore, try to think of the steering gear as a system serving the horizontal direction of travel (left and right), and the suspension as a system serving the vertical direction of travel (up and down). The following sections explain how to lubricate the suspensions. (If the suspension system knocks on its own, then you need to contact a professional.)

Springs lubrication

They are used to absorb shocks and keep your vehicle level. different types springs. It can be a coil spring, leaf spring, torsion shaft, or air spring. Some vehicles have leaf springs on the rear wheels and springs on the front. Executive cars, trucks and buses have a pneumatic suspension system. For more information on suspension types, see Chapter 11, “Steering and Suspension, or What Makes the Ride Enjoyable”. Now you will learn what you need to lubricate and how to properly lubricate the suspension, depending on its type.

Leaf springs. The leaf springs are attached at each end to the vehicle frame, which allows them to move freely. This mount usually has a rubber bushing that allows the mount to rotate easily, and also absorbs vibration energy and prevents the spring from reaching the passenger compartment (6). If the leaf spring has more than one leaf on each side, it is called a top spring. There are pieces of plastic between the leaf springs, called a squeak resistant plastic washer, which can be lubricated with suspension grease to prevent noise as the leafs rub against each other when shaken.

Spring springs. They look like springs on old-fashioned sofas. Most often the springs are installed in the front of the car, but there are models in which they are installed both front and rear (7 and 8 show the location of the ball joints and bushings on the spring springs).

Sometimes the springs have rubber pads at the top and bottom. If the springs are making a lot of noise, you can lubricate them at the top and bottom. Use a spray gun to apply lubricant.

Torsion shaft. This type of springs is widely used in sports and trucks. They are usually located parallel to the frame and accumulate to the control arms at one end, and at the other to the transverse structural element (9). The torsion shaft does not require lubrication. They can be adjusted; if your vehicle is raised too high or too lowered, the height can be adjusted by turning the adjusting bolt.

Air suspension. This type of suspension is based on the use of compressed air to maintain ride comfort and vehicle body height. By means of the built-in computer that signals the weight, it is possible to add compressed air when the weight of the vehicle increases. When you unload the car, the computer will send a signal to the valve, and it releases air (10). Usually in pneumatic

there is nothing to lubricate the springs. But still ask your consultant if you need to use a rubber conditioner to prevent premature wear of the air springs.

Hello everyone, on my classic VAZ-2106 the ball joint began to creak, I'm thinking about lubricating it, tell me what the creak is and how best to lubricate it? (Valentine)

Good afternoon, Valentine. As a rule, the occurrence of a squeak is associated with a deficiency the right amount grease, in particular - under the boot, directly in the ball joint itself. Lack of lubrication, in turn, can damage the boot. In domestic classic cars, two ball joints are installed - an upper and a lower one - but only the latter is subject to maintenance and is equipped with a special fitting through which lubricant is poured.

The service life of this unit depends on many factors; it varies from 15 to 130 thousand kilometers. Even a small crack formed on the boot can significantly reduce the resource. As a result, dirt and moisture will enter the hinge through the crack, so you should always diagnose the unit for mechanical damage.

Signs of ball breakage:

• knocking when driving on a road with holes and off-road;
• when you turn the steering wheel, a creak may appear;
• the car can drive unstably in a straight trajectory as a result of the wobbling of the wheels;
• rubber on the car wears out unevenly.

How to lubricate the support with your own hands?

This process is best done on an overpass or pit, with the vehicle positioned so that the front wheel is on the edge of the pit. By doing this, you can make room for the syringe with which you will pour the grease.

In order to properly lubricate the required structure, you should put the front of the vehicle on a jack, and you will need to install a stop under the beam. Further, under the lower arm it is necessary to install stands, after which the jack is lowered. By doing this, you can relieve the front suspension of your vehicle.

After that using wrench by 7, unscrew the plug located at the bottom of the support. Take a regular pharmacy syringe with a tube or a special syringe into which you fill in the lubricant "Solidol" or "Litol". You should not overfill, so the amount of the substance should be controlled through the boot itself - when you see that this element has begun to inflate, this means that lubrication is no longer needed. Please note that too much lubricant can damage the component.

Video "Lubrication of the support at home"

Details of this process are shown in the video (by VAZ 2101-2107, repair and maintenance).

The ball joint is an important suspension unit that provides the ability to rotate the wheel hub while maintaining its horizontal position. Structurally, the ball joint consists of two main elements: a cone-shaped pin with a spherical tip and a body, which has the necessary working holes. The pin is installed in such a way that it can rotate and swing at small angles. The body of the assembly is bolted to the suspension arm or pressed into it. To ensure rotation, plastic inserts are placed in the body, which take up free space up to the finger. Ball joint grease (if provided) is applied both directly to the body cavity and to the spherical finger tip.

Causes of ball joint breakage

During the operation of the car, the ball joints are subject to serious loads, which, depending on the suspension design, can take on a significant part of the car's weight, as well as impacts when driving on uneven road surfaces. The main reason for replacing the ball joint and disrupting its normal operation is the wear of the contacting metal surfaces in the process of friction, which leads to the appearance of a noticeable backlash: the finger begins not only to rotate, but also to move; in the worst case, it breaks out of the case. The causes of wear can be associated with both natural processes (aging of metal and other materials), and with an increase in specific loads on the mechanism, rupture of the boot or lack of lubrication in the hinge. The ball joint must be lubricated every time the unit is repaired or replaced. Manufacturers often indicate their recommendations for lubricating the mechanism, which allows you to maximize the life of the part and avoid violating the rules for installation and operation.

Ball joint grease

The ball joint is usually lubricated with lithium soap thickened lubricants. Lithium greases were developed back in the 1940s, have been produced since the 1970s and are still widely used due to their versatility, optimal average performance and low cost. The most famous greases from this family are Litol-24, SHRUS-4 and ShRB-4. However, the technology for the production of lubricants does not stand still, and modern manufacturers bring improved lubricants to the market, designed with new research and technology in mind, while keeping the price on affordable level... LLC "NPP" Mapsol "offers several similar products designed for use in wide range nodes of both automotive and other equipment. Our greases are produced on the basis of "Litola-24" with the addition of an additive package that significantly improves the properties of the base grease. Grease "MAPSOL-100" can be used in automotive units operating at temperatures up to + 200 ° C, has good antifriction and antiwear properties, is resistant to water washout. Grease for ball joints "MAPSOL-200" withstands more than high temperatures and is intended for industrial heavily loaded units of sliding and rolling friction of vehicles.

Before installing the ball joint, the grease is placed under the protective cover with a layer of 1:25 mm. To prevent the ring from turning, the threaded part is lubricated with a layer of 0.5 mm thick.

Diverse extraneous noise, so annoying the driver when driving, often have the same reason - insufficiently lubricated ball joints (SHO). Should we treat this as an annoying inevitability, or is it better to lubricate the supports? Each driver decides for himself, however, there are proven recommendations based on practical experience. It is preferable to follow them if you do not want to spend extra money due to problems with such important detail car as ball joints.

Lubricate or not?

Do ball joints need to be lubricated before installation and during operation? To give the correct answer, it is worth understanding the principle of the device of any of these supports. It can be arranged in different ways, but the presence of a ball joint, as well as a finger, is mandatory in it. The base is used to stop the hinge, the boot covers the top of the support.

During operation, the hinge is constantly displaced, which contributes to its rapid wear. In addition, dirt often accumulates in the empty space between the base and the boot, which interferes with the work of the part. An alarming sign in this case is the appearance of knocks and squeaks. To prevent this from happening, the space under the boot must be completely clogged with auto-lubricant. It is very important to know what is the best way to lubricate the ball joints for their most durable functioning.

How to lubricate?

How to lubricate the ball joint before installation? The most common options are:

• lithium-based;
• calcium-based.

Among lithium auto-lubricants, Litol-24 and TsIATIM-201 are popular. In them, oil and lithium soap are present in different proportions, they also differ in the composition of additional additives.

The stabilizing substances present in Litola-24 ensure good safety of the hinge and low consumption of lubricant during its operation. However, this automatic lubricant does not tolerate low temperatures well. CIATIM-201 stabilizes SHO to a lesser extent, but it better protects them from frost, and is cheaper.

Expensive lithium-calcium and calcium greases ( different kinds Shell Gadus, Grease Calcium, etc.) are recommended for high stress on parts, as well as when working in extreme temperature conditions.

So what kind of grease to lubricate ball joints? It depends on the following factors:

• the degree of intensity of the load;
• temperature;
• prices.

Based on these factors, for an ordinary driver operating his a car on the asphalt roads in conditions middle lane, lithium auto-lubricants are best suited as an acceptable compromise of price and quality. While in extreme conditions, calcium and plastic lithium-calcium greases are more suitable.

When to lubricate?

SHO is required to be lubricated before being installed at the factory. However, in some cases, especially when it comes to machines of "domestic assembly", this requirement may not be met. In addition, the displacement of the hinge during the operation of the vehicle leads to a consumption lubricant... The amount of lubricant is reduced and during downtime it dries out. That is why it is recommended to add lubricant not only during installation, but also periodically, after a certain period of operation. But how do you know when a part needs to be relubricated?

All SHO malfunctions are easily determined by ear already in the early stages, although modern diagnostics may be needed in the future. The first alarm signal for the driver is knocking and squeaking while driving. If they are heard exactly in those places where the SHO is located, then this particular node must be checked first of all. If there is no noticeable backlash, a timely update of the automatic lubrication will be a sufficient measure.

Experience shows that if one ball starts to "knock", it is better to lubricate them all, since they have the same resource.

How to lubricate?

How to lubricate the ball joints yourself? On most modern models cars lubrication SHO is made using a special syringe. The price of this tool is low and quickly pays off when you take into account the cost of the parts that it protects from its use. In this case, the lubrication procedure is extremely simple and does not require not only special skills, but even basic knowledge of a drill. However, this process is by no means so easy in all cases.

On a number of vehicles interior SHO with only one syringe is not available. This means that you have to cut the missing threaded fragments into parts. You cannot do without a drill and an appropriate attachment for metal carving. Another necessary tool for this is a conventional locksmith vice to fix the removed part. However, there is nothing here that the car owner could not do on his own, at home.

Even if you can lubricate the ball joints directly on the car body, doing so is usually not recommended due to the fact that this is a dirty job and you can get the body dirty. Each specific car model has its own characteristics, but general principle is the same everywhere. It is quite possible to remove the SHO without the appropriate devices, resting on the crowbar, while the assistant knocks it out with a sledgehammer. However, it is better to use a special puller, as it is much more convenient and does not threaten physical injury due to carelessness.

Further depends on the structure of the support. If the hinge is equipped with a nipple to which you can add lubricant, then there is no problem with a syringe. It is only necessary to perform the following steps:

• clamp the part with a vise;
• unscrew the nipple with a wrench or pliers;
• enter the grease with a syringe into the opened hole;
• close the nipple by tightening the protective plug.

Video instruction (the case when there is a technological hole).

On vehicles where no relubrication is required, a drill and a tapping tool have to be used. In this case, it is necessary:

• clamp the part in a vice;
• use a thin drill to drill a hole in it;
• cut a thread in it;
• pour grease into the hole with a syringe;
• close the hole with a suitable bolt for the thread.

Sometimes, if you don't have the right tools at hand, you still need to find a way to lubricate the ball joint without removing it. The sequence of actions is the same:

• the anther is pushed on with a sharp object;
• the edge of the gap formed is pushed back with the help of improvised means;
• grease is poured into the slot with a syringe.

Video (grease with a syringe).

If you don't want to waste time on self-lubrication, you can use the service of any car service.

Examples from the experience of car owners.

Oleg:

“If you have a Lada Granta, it is not so easy to lubricate the ball joint. It's all about the boot, which squeezes the metal ring from below, which makes it difficult to remove it. First I needed a small flat screwdriver, which I used for the boot. Then I had to use two Phillips screwdrivers different sizes to widen the gap. When it became wide enough for the nozzle of the syringe, I squeezed the lithol into it. "

Evgeniy:

“If ball joints are not equipped with plugs, grease fittings should be used. A grease gun is bought, and lithol is poured with a syringe until the grease starts flowing from under the boot. "

Yuri:

“If the ball joint has to be disassembled, it is better to fill it with light fuel oil, in which there is no graphite. This is necessary because the factory grease can thicken and without an additional portion of fuel oil under the boot it will clog everything with water and dirt. "
