Suspension bearing of the propeller shaft VAZ 2107 (2105, 2106, 2101) - replacement with photos and videos

Today there are fewer and fewer classic cars on our roads, and over the past few years not a single one has come to me for repairs. Therefore, when a client showed up in the morning with an old seven and offered to replace the crosspieces and suspension, I could not refuse because of the memories that came back.

But this is all rhetoric, and today we have to replace the VAZ 2107 driveshaft crosspiece and, as well as a bunch of outboard bearings, we still have to disassemble. The main signs of wear on the crosspiece are a characteristic loud click when starting, as well as vibration.

Signs of a faulty VAZ 2107 suspension bearing and how to check the driveshaft yourself

The first signs of malfunction and wear of the VAZ 2107 (PP) suspension bearing are vibration and knocking of the cardan when the car begins to move. After accelerating the car, the knocking gradually disappears, turning into vibration and noise. If there were no problems with balancing the axle before, but knocking suddenly appeared, then it is necessary to immediately diagnose the PP.

Diagnosis is performed in the following order:

1. Place the car on an overpass, lift or pit;
2. Locate the driveshaft under the car;

1. Check the play of the PP by moving the part by hand in the axial direction - free movement is not allowed;
2. Rotate the cardan and listen to how the bearing works - vibration, rolling, grinding, knocking are not allowed;
3. Inspect the product body, including the tightness of the bearing seals - lubricant leakage is not allowed;
4. Make sure that the outboard bearing and bracket are not loose;
5. The presented videos show how the VAZ 2101-2107 suspension bearing (injector) hums, as well as how to determine if the intermediate support is faulty.

Preparing tools

Replacing a car suspension cardan bearing is quite possible without the assistance of car service employees. The main thing is to carefully review the book, which describes how to repair and operate a specific vehicle. You also need to own the right tools and have a lift or overpass at your disposal. You may need a vinegar solution or a special liquid to decarbonize the fastening bolts if they have become rusty.

In principle, changing the outboard bearing of a VAZ-2107 or VAZ-2106 cardan will not differ much from replacing the same component on a Ford or Toyota. The scheme is similar everywhere, with some differences, but not dramatic ones.

To replace the bearing you will need two open-end wrenches for 12 and 13 mm, a hammer, a metal attachment, and at the same time pliers, thanks to which you can remove the locking rings. We must not forget about the special bearing puller, without which such a process simply cannot be carried out.

Car owners may have a question: can an outboard bearing be repaired? Yes it is possible. But here there are 2 options - either the bearing housing is disassembled for lubrication, or the bearing itself is replaced. In the second case, this is more appropriate, but only if it is not difficult for the car owner. In particular, for Toyota the following scenario is possible - the price of a new spare part costs 1500-6000 rubles, and a simple bearing of the same size costs 100-300 rubles. You can save money here.

Anyone who is disassembling a structure for the first time can follow the following recommendation: it is important to remember what is being unscrewed from where, what is being removed from where, the bolts and nuts should be placed in a jar or box. If they do not unscrew, then you need to soak them with a special liquid, otherwise you can either tear off the threads or completely break off the bolts.

Suspended bearing for the VAZ 2107 propeller shaft: dimensions, prices, how to choose, which one to buy

The design of the intermediate support for the propeller shaft VAZ 2101 - VAZ 2107 consists of a closed-type, lubricated, single-row radial ball bearing, which is located inside a housing made of metal and rubber. The ball bearing is secured with a retaining ring. The PCB body has fasteners in the form of a bracket with holes.

Ball bearing marking:

1. according to GOST 6-180605;
2. according to ISO 62305.2RS;
3. Factory (serial or catalog) number of the VAZ 2107 suspension support: 2105-2202078.

It is important to know:

Inspect the old suspension assembly to make sure the ball bearing is working properly. You may not need to replace the support and it will be enough to just change only the bearing, but more often the assembly is changed, and experts also recommend it.

The VAZ 2107 suspension bearing for replacement, the prices of which are presented in the table , is selected based on the recommendations of experienced auto mechanics and service station workers.

Below is a list of preferred manufacturers to purchase parts from. To the question “How much does a suspension bearing for a VAZ 2107 cost?” This table will answer in detail. Pay attention to the photographs of the original repair kits presented in the list.

How to make sure that the vibration is from the cardan

While driving, use the tachometer to notice the engine speed at which vibration occurs. Then, in another gear, increase the speed until the same phenomenon occurs.

1. If vibration occurs at the same speed, but in different gears, then the cause of the malfunction is not in the cardan, since its speed was different.
2. If the vibration disappears or decreases when operating in a different gear at the same engine speed, then check the possible causes of the malfunction described above.

How to replace an unusable part yourself

Before you begin, you should prepare the following tools:

• assorted car keys;
• a special device called a jack;
• reliable mount made from high-quality base;
• a new CV joint that is suitable for the VAZ-2110, and lubricant for it.

After all the tools are prepared, you can begin step-by-step replacement of the CV joint boot:

• the machine wheel is removed and the steering knuckle is removed from the support;
• Using a car key of the appropriate size, the CV joint is unscrewed and removed from the hub. In order for this process to be effective, it is recommended to use a rubberized hammer or a special drift, which is made in a soft design;
• the retaining clamps are unscrewed, and the worn part is cut off using a sharp tool. After removal, you should thoroughly wipe the entire surface so that no old grease remains, turn the CV joint until the stop ring connects;
• If the turn is made correctly, then separating the CV joint from the axle will be quite easy and simple. Next, you should simply remove the worn boot, install the connecting clamp in its original place;
• before installing a new element, you should prepare it, that is, you need to fill the installed stopper with automotive lubricant, develop the part according to the instructions;
• the developed element must be correctly installed on the axle using a rubberized hammer. The CV joint must be carefully secured to the stupor;
• the remainder of the automotive lubricant should be squeezed into the boot of the VAZ-2110 CV joint, put a connecting clamp on top and securely fix it.

The replacement will be finally carried out only if you install all the removable parts of the machine in their original places and securely fix them. That is, it is necessary to install the steering knuckle in its original place and securely screw it with the connecting nut to the ball joint. All connectors are put back in their original places and securely fixed to the support.

This replacement of the CV joint boot is not the only one; there are several other options for carrying out the work. However, this method is the simplest, and even a novice car enthusiast can cope with it.

The CV joint on a VAZ 2114 is replaced after diagnosing its malfunction. As a rule, this unit reliably serves for 100 thousand km. The CV joint can fail earlier if the car owner does not monitor the integrity of its boots and does not change them on time. Then, through cracks or breaks, a lot of dirt gets into the hinge mechanism, as a result of which the unit very quickly becomes unusable. Signs of a faulty part are a knocking and crunching sound when the front wheels turn in any direction.

• a set of spanners or sockets;
• pliers;
• hammer;
• puller for pressing out the ball stud;
• vice;
• wheel wrench and jack;
• screwdriver;
• thick lubricant “CV joint-4”;
• rags.

New bearing installation process

Follow our detailed instructions to install the outboard bearing correctly:

1. First, clean the cardan shaft from accumulated dirt and dust. Then it should be wiped and thoroughly lubricated, a similar procedure should be carried out with a new ball bearing.
2. Find a steel pipe with a diameter of more than 3 cm, we will need it to press in the bearing. It must be selected wisely, since the entire load upon impact should be distributed only to the inner ring of the bearing.
3. The ball bearing must be pressed in until there is a gap of half a centimeter left.
4. After this, assemble the cardan in accordance with the marked marks.
5. All that remains is to lock the washer of the bolted connection. Now you can check how the cardan rotates.
6. After this, reassemble the cardan in the reverse order, this will not be so difficult, the main thing is not to rush.

conclusions

Replacing the steering tips on a VAZ-2114 car is quite simple, but the process itself can take a lot of time and effort, since the fixing nut will not always be unscrewed easily. If the described process seems complicated to the motorist, then you need to contact a car service center, where they will always help with replacement. Separately, it is worth noting that the chassis parts must be changed on time to avoid the tragic consequences described in the article.

Suspension support design

Where is the outboard bearing located?

Basic dominant

the object is a rolling or sliding bearing of a specific design, inserted into a metal frame. The free zone between the outer race and the inner sphere of the housing is covered with a rubber ring designed to dampen vibrations of the cardan. The leakage of lubricant and the penetration of dust are prevented by rubber bands with sealing covers that cover the gaps between the rings of the product.

The purpose of the bearing bushing is to hold the joint shaft in a calculated position with allowable displacement.

The structure, assembled into a single load-bearing unit, is attached to the machine frame through the mounting brackets of the base support.
