How to lubricate ball joints. How to lubricate a ball joint yourself? Do I need to lubricate the ball joint before installation?
A ball joint is a car suspension part that serves to connect the lever and the hub. All motorists know very well that it is necessary to monitor ball joints and lubricate them regularly. If the ball joint is worn out, it must be immediately replaced with a new one. Some car enthusiasts believe that regular lubrication of bearings is much cheaper than replacing a worn-out unit. That's why they drill a hole in the center of the hinge for lubrication and put a plug there. We will explain to anyone who wants to know how to lubricate a ball joint. For lubrication, you need to use a special syringe with lithol, which is screwed into the hole through which the lubricant enters the hinge. You can also use a regular medical syringe for this. To do this, you need to pierce the ball joint boot with a needle and introduce TAD-17 lubricant inside. Annual lubrication in this way will allow you to do without replacing ball joints for more than 100 thousand km.
It is impossible to say exactly how the ball joint knocks. One can only assume that the knock that occurs when driving on uneven roads is the knock of the ball joint. In order to check this, you need to lift the car on a lift. First of all, check the condition of the anthers, since if the anther is damaged, dust and dirt immediately gets there, and this instantly shortens the service life. After which you need to check the play of the ball joint and if there is play, it means that it is time to change the ball joints.
For those who do not know what a ball joint looks like, let us explain. That this is part of the pendant, which looks like a fixed ball with a finger. Now that you know what it looks like, let's choose a good spare part for your car. When inspecting the ball joint, you should pay attention to the forged pin, the threads of which should be rolled. The finger should turn easily without jamming. The boot must fit snugly against the body of the finger, and there must be a certification mark on the box. Now you know how to choose ball joint.
The ball joint is one of the most important details pendants. Since it is she who keeps the wheel in a vertical position and prevents it from turning out. The safety of your ride directly depends on its quality and wear resistance. After all, if the ball joint pin flies out of the base, then this can end disastrously not only for the car. Therefore, we strongly recommend using tips on how to check the condition of the ball joint to avoid sad consequences. Choice quality parts Not only will it allow you to travel more, but it will also save you from possible troubles. Good luck on your journey.
The ball joint is important node suspension, providing 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 housing in which there are the necessary working holes. The finger is installed in such a way that it can rotate and swing at small angles. The assembly body is bolted to the suspension arm or pressed into it. To ensure rotation, plastic inserts are placed in the body, which occupy the free space up to the finger. Lubricant for ball joints (if provided) is placed both directly into the housing cavity and onto the spherical tip of the pin.
Causes of ball joint failures
During the operation of the car, the ball joints are subject to serious loads, which, depending on the design of the suspension, can take on a significant part of the car’s weight, as well as impacts when driving on uneven surfaces. road surface. The main reason for replacing the ball joint and disrupting its normal functioning is wear of the contacting parts. metal surfaces in the process of friction, which leads to the appearance of noticeable play: the finger begins not only to rotate, but also to move; in the worst case, it breaks out of the body. The causes of wear can be associated both with 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 whenever the unit is repaired or replaced. Manufacturers often indicate their recommendations for lubrication of the mechanism, which allows you to maximize the service life of the part and avoid violations of installation and operation rules.
Ball joint lubricant
Ball joint lubrication is typically done with lithium soap thickened lubricants. Lithium greases were developed back in the 1940s, produced since the 1970s and are still widely used today due to their versatility, optimal average performance and low price. The most famous greases from this family are Litol-24, CV joints-4 and ShRB-4. However, lubricant production technology does not stand still, and modern manufacturers are bringing to the market improved lubricants, developed taking into account new research and technology, while keeping the price at an affordable level. NPP Mapsol LLC offers several similar products designed for use in a wide range of components of both automotive and other equipment. Our lubricants are produced on the basis of Litol-24 with the addition of an additive package that significantly improves the properties of the base lubricant. MAPSOL-100 lubricant can be used in automotive components operating at temperatures up to +200°C, has good anti-friction and anti-wear properties, and is resistant to washing off with water. Lubricant for ball joints "MAPSOL-200" withstands more than high temperatures and is intended for industrial heavy-duty sliding and rolling friction units of vehicles.
Before installing the ball joint, lubricant is placed under the protective cover in a layer of 1:25 mm. To prevent the ring from turning, the threaded part is lubricated with a layer 0.5 mm thick.
Hello everyone, the ball joint on my classic VAZ-2106 started to creak, I’m thinking about lubricating it, tell me what the creaking is fraught with and what’s the best way to lubricate it? (Valentin)
Good afternoon, Valentin. As a rule, the occurrence of squeaking is associated with a lack of the required amount of lubricant, in particular, under the boot, directly in the ball joint itself. Lack of lubrication, in turn, can cause damage to the boot. In domestic classic cars, two ball joints are installed - upper and lower - 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 service life. As a result, dirt and moisture will enter the joint through the crack, so you should always diagnose the unit for mechanical damage.
Signs of ball failure:
- knocking when driving on roads with potholes and off-road;
- creaking may occur when turning the steering wheel;
- the car may drive unstably along a straight path as a result of wobbling wheels;
- The tires on your car wear out unevenly.

How to lubricate a support with your own hands?
This process is best carried out on an overpass or pit, positioning the vehicle so that the front wheel is mounted on the edge of the pit. By doing this, you can make room for the syringe, which you will use to fill in the lubricant.
In order to properly lubricate necessary design, the front part should be placed vehicle on a jack, and you will need to install a stop under the beam. Next, you need to install stands under the lower arm, after which the jack is lowered. By doing this, you can relieve the front suspension of your car.
After this, using spanner at 7, you should unscrew the plug located at the bottom of the support. Take a regular pharmacy syringe with a pipe or a special syringe, into which pour the lubricant “Solidol” or “Litol”. You should not overfill, so the amount of 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: increased amount lubricant may also damage the component.

Details of this process are shown in the video (author - VAZ 2101-2107, repair and maintenance).
Lubrication of ball joints consists of wiping the grease nipple, installing a syringe (if necessary, you can use an adapter) and carefully squeezing the grease into the support. Now you will see how to do this correctly.
1. Understand how many lubrication points your machine has and where they are located. previous section “Finding lubrication points”.
2.Wipe the first grease nipple and try to fit the syringe onto it. Did it work? If not, you will need an adapter. Do you have it? If not, you will need an extender.
3.Fill the syringe with lubricant.
To do this you will need the lubricant used for the suspension.
4.Move the syringe to the grease nipple and carefully squeeze out some grease (5).
Never fill the supports to capacity with grease. The amount of grease can be checked by squeezing the ball joint boot. It shouldn't be tight. When the boot is hard and full, squeeze some grease out if there is a hole in this type of support. But if this support is a sealed type, then you need to fill the case completely. If the boot looks full, don't add any lube at all and move on to the next support.
5.Repeat paragraphs. 2 and 4 until you have serviced all the supports.
6.If you have overdone the lubrication of the sealed support, use a suitable socket wrench to unscrew the grease fitting (counterclockwise). Squeeze out some grease and screw the grease fitting back on.
Dealing with a broken joint - V, is not the most pleasant task; Be careful and squeeze out the lubricant in small portions. I know because I've had to deal with it. How difficult it is to deal with that slippery little grease fitting.
7.If one of the covers bursts, it must be replaced immediately.
The parts that the covers protect are very important, so if you don't replace them, you could end up paying a lot of money for repairs after a short drive on a non-functioning mount (or even possibly losing control of the car completely).
When purchasing a new car, ask the maintenance manager. Does this model have any weak points where it would be nice to install an additional grease fitting? My car had a couple extra
installed, it is convenient and inexpensive. If you constantly hear some kind of squeaking noise when driving, ask if it will disappear if you install a grease nipple in that place.
Technologically, it is designed so that the suspension also includes a steering gear, but it seems to me that, based on their functional purpose, it is better to separate these two systems. Therefore, try to think of the steering gear as a system that serves the horizontal direction of movement (left and right), and the suspension as a system that serves the vertical direction of movement (up and down). The following sections explain how to lubricate the hangers. (If the suspension system is knocking on its own, then you need to contact a professional.)
Spring lubrication
Used to absorb shock and keep your vehicle level. various types springs It can be a coil spring, leaf spring, torsion bar or air spring. Some cars have leaf springs on the rear wheels and coil springs on the front wheels. Executive cars, trucks and buses have an air suspension system. For more detailed information about suspension types, see Chapter 11, “ Steering and suspension, or What makes a ride enjoyable.” Now you will learn what you need for lubrication and how to properly lubricate the suspension depending on its type.
Leaf springs. Leaf springs are attached at each end to the vehicle's frame, allowing 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” into the passenger compartment (6). If a leaf spring has more than one leaf on each side, it is called a multi-leaf spring. There are pieces of plastic placed between the spring sheets, called anti-squeak plastic washers. They can be lubricated with suspension lubricant to prevent noise as the sheets rub against each other during shaking.
Spring springs. They look like the springs on old-fashioned sofas. Most often, springs are installed in the front of the car, but there are models in which they are installed both in the front and rear (7 and 8 show the location of ball joints and bushings on spring springs).
Sometimes spring springs have rubber pads at the top and bottom. If the springs make a lot of noise, you can lubricate them at the top and bottom. Use a spray bottle to apply lubricant.
Torsion shaft. This type of spring is widely used in sports and trucks. Usually they are located parallel to the frame and accumulate to the control levers 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 car is raised too high or too low, the height can be adjusted by tightening the adjuster bolt.
Air suspension. This type of suspension relies on the use of compressed air to maintain ride comfort and vehicle height. Using the built-in computer, which signals the weight, you can add compressed air when the vehicle's weight increases. When you unload the car, the computer will send a signal to the valve, and it will release air (10). Usually in pneumatic
there is nothing to lubricate on the spring springs. But still ask your consultant about the need to use a rubber conditioner to prevent premature wear of the air springs.

Sometimes drivers may have a question about how to lubricate a ball joint. This topic usually arises when there is knocking in the suspension caused by the depletion of standard lubrication. As a rule, it is the lack of a lubricant that leads to the need to replace this suspension element. The use of additional greases extends the service life of the support by 2 times. Moreover, if there is special tool, as well as minimal skills in car repair, every car enthusiast can cope with restoring the performance of the ball joint. The main thing is to choose the right type of lubricant to solve this problem.
Support structure
How to lubricate the ball joint? Before answering this question, it is advisable for you to familiarize yourself with the structure of this part. Then you will be able to understand more clearly how to properly lubricate the assembly. The main element here is a ball joint with a pin. It rests on the base, and the structure is covered with anther on top. A large amount of grease is packed into the base and under the boot. It is calculated for the entire life of this structural element.
During operation, the hinge constantly moves relative to the base, the lubricant is slowly produced, and during long periods of downtime, it simply dries out. Therefore, knocking noises gradually begin to appear. If you do not pay attention to this sign, then backlash begins, and the part becomes unusable due to high wear.
What do they lubricate with?
As a rule, various lithium-based lubricants are used for ball joints. These compounds work great with high loads that arise during the operation of the ball joint. It is necessary to understand that it is worth choosing the right substances. The composition of lithium greases is derived from petroleum oils.
During the manufacturing process, the oil is thickened by adding lithium soap. This allows you to achieve the best consistency. At the same time, the combination of petroleum oil with fatty acids lithium soap has an additional preservative effect. In practice, there are several varieties similar type lubricants They differ in the ratio of oil and lithium soap in the composition, as well as additional additives. The most common options are:
- . This is perhaps the most common option among drivers. There are several reasons for this. Firstly, this lubricant has a good temperature range, which allows it to be used almost throughout our entire territory. Thanks to the presence of stabilizing additives, the lubricant lasts quite a long time, providing reliable protection from any negative factors. It should be especially noted that Litol-24 is not afraid of any temperature changes, so you don’t have to worry that when driving through snow or water, the ball will be left without protection;
- . This lubricant is less commonly used in ball joints. Compared to Litol, it has a lower threshold of permissible temperatures. It does not freeze even at minus 60 C. Therefore, it is often used in the regions of the far north. Although CIATIM has lower technical characteristics, in comparison with Litol, resistance to low temperatures is an advantage. This lubricant also has a lower cost.
If you go to the store to buy ball lubricant, you should not buy expensive compounds from famous manufacturers. Usually, they are practically no different from their cheaper counterparts. Therefore, you can freely take the simplest Litol-24 and not bother. But be sure to look at the composition. Calcium lubricants are always more expensive. Therefore, if you want to opt for calcium lubricants, then be prepared to spend a little more money.
When choosing substances, it is advisable to pay attention to machine operating conditions. If you encounter extreme temperatures, then it is better to take a lubricant that can work in such conditions. low temperatures. This will reduce the level of wear of parts when working in winter time. In other cases, there are no special features when choosing.
The work itself
To extend the service life of the suspension, it is recommended to check this unit at the first signs of knocking on the ball joints. If there are no noticeable backlashes, then it is enough to renew the lubricant in the support. To do this you will need a special syringe. It is inexpensive, taking into account the average cost of ball joints, this money is recouped quite quickly. Also, on some machine models you may need a drill and a device for cutting threaded fragments. It would be good if there were a vice available. In some cases, ball lubrication can be done directly on the car, but this is not always justified, because it is very difficult to ensure the cleanliness of the procedure.
To begin, remove the ball joint from the car. Here the instructions for repairing your car will help you. On all models, this work has its own characteristics, so it is better to clarify these nuances so that problems do not arise in the future. After dismantling, inspect the ball joint. We are interested in the base of the part. On many models there is a nipple there to add additional lubrication to the joint. This will allow you to update your workforce without much difficulty.
In this case they do as follows:
- We clamp the support in a vice, just do it carefully;
- Unscrew the nipple for lubrication. Depending on the model, you will need a wrench or pliers;
- Fill the syringe with a sufficient amount of lubricant. After this you can enter required quantity substances inside the part;
- We tighten the protective plug, it is advisable to move your finger, it should move much tighter than it was before.
It will be a little more difficult in the case of a maintenance-free support. Some foreign cars do not provide the ability to add a new portion of lubricant. In this case, you will need to use a drill:
- The support is clamped in a vice, after which a hole is made in the base with a thin drill;
- It is threaded;
- Next, add lubricant using a syringe;
- A suitable bolt is screwed into the hole.
Conclusion. As a rule, many knocks in the suspension can be caused not by wear of parts, but by a lack of lubrication in them. Therefore, the question of how to lubricate a ball joint is not surprising. The lubricant in this hinge unit is produced much earlier than the failure of the entire part occurs. Therefore, most the best option the support will self-lubricate. This will significantly reduce the cost of servicing your car, because you can increase the service life of the ball joint by 2 times.
