Замена подшипников на полуоси ВАЗ 2121

The VAZ 2121 is a reliable and durable vehicle, but like any machine, it will eventually require maintenance to keep it running at its best. One of the critical parts that need attention is the axle shaft bearings. Over time, they can wear out or become damaged, leading to issues with the car’s handling and performance. Fortunately, replacing the bearings on the VAZ 2121 is a straightforward process that can be done at home with a few tools and some patience.

Before starting the replacement process, it’s essential to gather the necessary tools and equipment. The most important ones include a jack and jack stands, a socket set, pliers, a pry bar, a hammer, and a bearing puller. Once these are on hand, begin by raising the car off the ground using the jack and securing it in place with the jack stands. It’s crucial to ensure that the car is well-supported, as it will be lifted entirely off the ground during the process.

The next step is to remove the wheel and the brake caliper from the affected axle. Start by loosening the lug nuts and then removing the wheel. The brake caliper can be removed by loosening the bolts that hold it in place and then carefully pulling it off. Be careful not to damage the brake line during this process. Once the caliper is removed, hang it out of the way using a wire or rope.

Now it’s time to remove the old bearings from the axle shaft. This is where the bearing puller comes in handy, as it will allow you to safely and easily extract the old bearings. First, remove the seal from the back of the bearing. Then, attach the bearing puller to the bearing and use it to gently pry the bearing off the shaft. Repeat this process for both the inner and outer bearings.

Before installing the new bearings, it’s essential to clean the axle shaft thoroughly. Use a wire brush and some solvent to remove any grime or debris, being careful not to damage the surface of the shaft. Once it’s clean, apply a thin layer of grease to the shaft to help lubricate the new bearings.

Now it’s time to install the new bearings. Start with the outer bearing and use a hammer and a socket to gently tap it into place. Be sure to use a socket that is the same size as the outer part of the bearing to avoid damaging it. Once the outer bearing is in place, install the seal on the back of it.

Next, install the inner bearing in the same way, being careful not to damage it during the installation process. Once both bearings are in place, install the brake caliper, the wheel, and the lug nuts.

Finally, lower the car to the ground and tighten the lug nuts to the manufacturer’s recommended torque specs. Take the car for a test drive, paying close attention to the handling and performance. If everything feels good, congratulations! You’ve successfully replaced the bearings on your VAZ 2121 axle shaft.

In conclusion, replacing the bearings on the VAZ 2121 axle shaft is a relatively simple job that can be done by most home mechanics. With the right tools and some patience, it’s possible to complete the job in a few hours and restore your car’s handling and performance. If you’re not confident in your ability to complete the job, don’t hesitate to seek the help of a qualified professional. With the right care and maintenance, your VAZ 2121 will serve you well for many years to come.
