Replacement of the semi-axle bearing VAZ-2107 on its own

One of the most important components of the rear axleVAZ-2107 is the semiaxis. It is this part that transmits the entire torque from the gearbox to the wheels. For its free rotation, a bearing is provided. Its main task is to ensure a uniform and smooth rotation of the axle of the rear axle when the car moves. The element is located in the rear axle, behind the brake drum. Replacement of the bearing of the rear axle VAZ-2107 is required not often. But in case of malfunctions, do not hesitate to repair it. So, let's look at how the bearing of the semi-axle on the VAZ-2107 is replaced independently.

Symptoms of a malfunction

There are several symptoms that indicate a breakdownof this element. Like any other bearing, it begins to emit a characteristic noise in the event of a malfunction. At first it will be a barely noticeable rustle. But soon he will pass into an unbearable rumble. The main symptom, which says that the car VAZ-2107 requires replacing the semi-axle bearing, is the noise from the rear wheels. It occurs during acceleration and deceleration. It also increases when you turn the car.

Why can not hesitate with replacing the bearingsemiaxis on the VAZ-2107? The fact is that on the faulty element the holder crumbles and the balls fly out. Soon the bearing can jam at all. This leads to an uncontrollable skid of the rear axle.

Cost of spare parts

The price of the new semi-axle bearing cana little fluctuate depending on the manufacturer (but all within reason). So, the product of the company "Master" costs about 125 rubles apiece. More expensive - bearings GPP. They are sold for 250 rubles. A set of bearings from the firm "Tork" can be bought for 450 rubles. In this case, one piece is sold for 300. As for the semi-axle shaft seals, they can be purchased for 30-50 rubles. By the way, all these products are interchangeable on all classic models of the VAZ and on the "Muscovite" model 2141. This is a very big plus.

Below we give technical data on the VAZ bearing of the half-axle:

• The inner diameter is 30 millimeters.
• Length - 0.07 meters.
• Height - 0.02 meters.
• Width - 19 millimeters.
• Outer diameter - 72 millimeters.
• Product weight - 340 grams.

Preparing for replacement

VAZ-2107 has a fairly simple device,therefore, it can easily be served by hand, without specialists. Replacing the axle bearing on the VAZ-2107 can be done both in the garage and on the street. The presence of a viewing pit or hoist is not necessary (although this will significantly speed up the process). The main thing is a complete set of tools and a flat, solid surface for work (so that the machine stably stands on the jack).

Now in detail about what tools weneed to replace. During the operation, we will need an open-end wrench for 10 and an end wrench for 17. The latter is recommended to be redone by welding the T-head to the driver. We also need a regular VAZ jack, fixing the shoes (stops) and balonnik. As for spare parts, in addition to the bearing, we need a new axle seal and a locking sleeve.

Getting Started

Now consider how to replacebearing axis on the VAZ-2107 do it yourself. We set the car on a flat surface, put stops under the front wheels (since we have a rear-wheel drive car and fix it “in gear” will not work) and tear down the wheel bolts. What needs to be done next? After that jacking the back of the machine. We put a safety bar under the body, which will save the car from accidental fall (you can put the wheel removed). Then use the socket wrench on 10 to unscrew the guides and remove the brake drum. If the latter is tight, use a hammer. It is necessary to strike blows accurately, through a wooden bar.

Next key on the "17" unscrew the bolts throughflange holes, fastening the Zhiguli semi-axis itself. Last we retrieve outside. Please note that the axle shaft can sit tightly and be difficult to dismantle. What to do in this situation? We need to put the wheel on two bolts and sharply pull it. So we shoot the product out. If this does not help, you should dismantle the shaft by unwinding it clockwise and counterclockwise.

Installing a new bearing

First we need to remove the old one from the axis.element. This will require an anvil or a steel object similar to it (it may be a piece of railway rails). Install the axle shaft on the anvil so that the flange of the part does not touch the surface of the rails. We cover the bearing with a dense cloth and once again check the position of the part. Twisted axes are not allowed. With the help of a hammer and chisel (we install it in the upper part of the bearing cage) we strike the element. Our goal is to break the clip, then remove the separator and knock down the intake sleeve. This can be done with the same chisel. Next, extract the inner clip. It can be cut with the help of the grinder.

After the old item was successfuldismantled, you can begin to install a new one. Carefully inspect the bearing seat. It should not be deformed. A new product is inserted using a hammer and a piece of pipe of the appropriate diameter. Next, install the stop sleeve, preheating it in a fire or using a blowtorch. So that the lubricant in the new bearing does not overheat, we wrap its holder with a wet rag. Remember that with every temperature increase the lubricant changes its structure. She can simply flow out.

This completes the installation of the G-axis bearing. The assembly of elements is performed in the reverse order. Do not forget to install a new axle oil seal.

Helpful advice

Replacing the axle bearing on the VAZ-2107,It is recommended to inspect the condition of the rear shoes and the working cylinder. Access to them will be opened immediately after dismantling the drum cover. If the items are worn, change them too. So at one time we will do a full maintenance of the machine in a relatively short time. All work will take you one and a half to two hours of time.

Conclusion

So, we figured out how to replacebearing axis on the VAZ-2107. At the end of the work do not forget to make a note in the logbook about what was replaced and on what mileage. Accounting for work performed allows us to reduce unforeseen faults to zero.
