For many drivers, replacing the ball joint seems like a simple action. Nevertheless, Renault Logan is very different from classic cars, so you need to be careful and some skills. Do not immediately decide on independent action, in some cases should take the help of professionals to avoid making mistakes.
Is it worth it to repair yourself?
Ball support will require parsing the chassis, and will have to spend a lot of time and effort. Let's pay special attention to some points:
- After removing the nut to detach the fist, it must be knocked out with a soft metal knockout.
- The finger of the ball and fist support is untwisted with a powerful screwdriver.
If you do not take into account this, you can ruin the details of the car Renault Logan. Replacement should be carried out with special accuracy, and after all domestic drivers for a long time have got used to rough actions. Foreign car will not tolerate this, so do not immediately rely on your own strength and knowledge.
Works in the service center
Experienced service center staff copes with repair work much faster. For them, replacing the support is the simplest task, which takes 1-2 hours. Experienced motorist probably prefer to use the services of auto mechanics. During the repair, many important points must be taken into account to avoid mistakes.
Renault Logan does not just require accuracy. Its parts are distinguished by connections and terminals from domestic models. For this reason even experienced drivers will face serious difficulties when replacement is required. Incorrect actions will lead to new breakdowns and long engine repairs, which once again recalls the importance of experience and professional skills.
Today, Renault Logan is widely used throughout the country. Do not rely on your own knowledge when doing repairs. In the service centers the masters know better how to cope with a particular problem.
Operation of the car on bad roads is able to disable this node. Meanwhile, the ball bearing plays an important role in the running gear of the car and can not be delayed with its repair.
What is a spherical support?
Ball support is a chassis element that combines the hub and the front suspension link. It is a component of the pivot and ensures its mobility, and the fist, in turn, interacts with.
Thus, the spherical support participates in the rotation of the wheel and without it maneuvers are not possible.

Additionally, the unit ensures correct fixation of the hub and wheel in the horizontal plane at the time of vertical movements.
How many ball bearings on Renault Logan?
Renault Logan is equipped with a front suspension type McPherson. This means that in its design there is only one ball from below - on each side of the front axle. The part is located on the lower arm under the hub. It can be clearly seen when the car is in a suspended state or on a pit.
Typical malfunctions
The signs of a failed node include:
- A dull thud on the bumps.
- in the cold season. They can appear in connection with the torn anther, through which moisture penetrates and the lubricant freezes.
- Increased effort and the appearance of squeaking and knocking while turning the steering wheel.
- Poor stability of the machine even when driving in a straight line. Need to adjust the course of the wheel.
- Accelerated and uneven wear of tires.
Threatens
If you do not follow the condition of the ball joint, then in the end it can lead to major repairs. The basis of the node is the body and the so-called finger.
Excessive shock loads create a strong friction between these two parts and the gap gradually grows between them (the finger "hovers" inside the housing).
At a critical moment, the finger simply pulls out of the body and the wheel is detached at the bottom of the hub. Further operation of the car with such a malfunction is impossible - only with the help of an evacuator.

Replacing the ball for Renault Logan takes a long time, but the main problem with this procedure is a very specific tool. On replacing the ball on Renault Logan in all the details we'll talk about in the article.
How to understand that you need a replacement ball for Renault Logan
First, we set the car on a level platform, or above the pit. The second option is most preferable, ideally, of course, use a lift, but even a pit is not for everyone. The bottom line is to unload the suspension, namely, to subdivide the front wheel.
Now we need to swing it from side to side, the ball is determined in the vertical plane. Of course, it happens that its "shakiness" is also visible in the horizontal, but this happens rarely enough. There should not be a finger loophole, it's logical.
In general, the first prerequisites may be a knock in the front suspension, which manifests itself in both small hummocks and large pits.
Tools for ball replacement on Renault Logan
This article concerns Logans of absolutely any year of release, the suspension at them remained practically identical. So, to replace the support we need the following set of tools:
- Horn and mantle wrench on 18;
- The heads are on 16, 17 and 18;
- Head or key on 13;
- A hammer;
- Balloon wrench or head on 17 with a collar;
- Extension for extrusion and ball fitting;
- A new ball bearing.

How to replace the ball joint on Renault Logan
So, it is already clear that for this we need to remove the lever. Of course, we put the car on a level platform, put on the handbrake, rollers under the wheel on both sides. These are elementary safety rules, the neglect of which can cost not only material losses.
Remove the wheel, and then unscrew the nut of the ball joint. Here it is wound not on the finger itself, but on the bolt, which pulls together a kind of collar, into which, in turn, the finger of the ball comes into play.
Now remove the plastic cover and unscrew the bolt by 13. Then the same "stick" is attached to the same bolt as the silentblock lever, unscrew the nut by 18. This is likely to be difficult, because they are always tightened, as they say, from soul.
We remove the "stick", unscrew one more nut on the same bolt. Now unscrew the second bolt securing the lever. Often, the car is not equipped with a stabilizer bar, which can only be on hand. If it still exists, unscrew the stabilizer bar.
Now we remove the lever, we put the mandrel from the bottom, we kick out the ball, we slaughter the new one, we see how it came in, if it's very easy, that is, it makes sense to get to the nearest service station where there is a semi-automatic and grab a ball for two potholders. In this there is no collective farm, this is an elementary reinsurance, with the next replacement they can easily be cut off by a Bulgarian.
Install the lever in place, only first you need to insert a ball ball, and then hammer the silent blocks into place, otherwise it's almost impossible to insert the finger into the pin. In conclusion, it is worth recalling that the tightening of the bolts of the silent blocks is done under load, that is, under the weight of the car, for this you have to put the wheel in place, and then tighten the bolts. Yes, then we'll have to remove the wheel again, in order to fasten the very "stick" that holds the stretcher for the bolt of the silentblock, but what to do. On this replacement of the ball bearing Renault Logan finished.
