Smooth and correct wheel rotation on the cardirectly related to the bearings. This type of bearings is called stupic, and they are installed both on the rear wheels and on the front wheels. They are needed to reduce friction. When they wear out, the wheels are skewed and, as a consequence, the rubber is rubbed off. And if the bearing is already crumbling while driving, the wheels can jam. But what if the bearing broke? This will be written just below.
Replacement of the front hub bearing on the "Niva Chevrolet"
Of course, it is very important to pay great attention tothis part by car. Especially on the "Niva Chevrolet". Since SUVs are usually most often used in difficult and extreme conditions, their bearings are prone to wear most. It is very important to make a timely replacement of the front hub bearing on the "Niva Chevrolet", it is quite possible to do it yourself. Why not in the workshop? In such places very like to put poor-quality bearings, so it's better not to take risks and do everything yourself. A detailed plan for bearing replacement will be described below.
Hub Construction
To understand exactly how to replace the bearing, you needfind out what the hub is. This is a structural detail of the car that connects the wheel to the shaft. A pair of bearings in the form of a cone are responsible for the operability of the hub, its rotation on the shaft. An important and most important feature of the hub is the possibility of adjusting the play. But when the car is used for a long time, the sliding mechanism is erased, and this gap increases in size. Because of this, the wheels begin to lose their original shape, they oscillate on the axle and, ultimately, wear off. To eliminate this problem, you need to replace these parts. The article presents a photo of the replacement of the front hub bearing on the "Niva Chevrolet".
Bearing Design
These parts consist of external and internalseparators. They play a very important role in the design, help reduce the friction of the wheels on the axle. Due to friction, a mechanical force is applied to the rollers and a very large volume of thermal energy is released. They can heat up to 250 degrees. Of course, not all metals can withstand such high temperatures, which is why the rollers are made from special steel, which can withstand heating up to 440 degrees. If they are not lubricated, they can reach this temperature and break down. Therefore, it is important to use only special lubricants that prevent too much heating.
When do I need to replace?
There are only two reasons, because of whichIt is necessary to replace the bearing of the front hub on the "Niva Chevrolet". Strange sounds in the front, for example, grinding or rumbling. Large backlash of the front wheel and, as a consequence, the erasure of rubber. For an accurate analysis, you need to disassemble the entire mechanism and check for malfunction.
Bearing replacement
First, you need to remove the front hub mechanism,then remove the sliding mechanism and install new parts. Here is a simple diagram. Let us analyze it in more detail. Use the jack to remove the hubs. We disconnect a support with колодками. Unscrew the adjusting nut and remove all the parts from the mechanism of the front wheel. Now that all the excess parts have been removed, you can move on to retrieving the bearing. It is removed using a special puller. Then remove the stuffing box and ring plate. After that, you need to remove the inner bearing, it is removed with a chisel. They need to work carefully so as not to damage important components of the machine. In the same way, the outer ring is removed.
Installation of new parts
Now you need to install new parts.For this we will prepare new videos. Thoroughly grease them. For lubrication is best suited "Litol-24", it can withstand very high temperatures, in contrast to the solidol, which can withstand only 100 degrees. Replacement is made in a complex, you need to immediately install a pair. Before lubricating, treat the part with a file. Using the pipe, insert all the parts into place and close the oil seal. Assembly of all parts must be carried out in the same manner as removal. After you have collected everything, your work is finished. You can enjoy your new bearings on your "Chevrolet Field". Now you need to check the rotation of the wheels.
Outcomes
As you can see, replace the bearings on the "Niva Chevrolet"not so difficult. So do not give the car to the car service. Bearings though are intended for long use, but they can not bear strong blows. And this happens quite often, even when hit in a small pit. However, the part does not get damaged immediately, cracks are formed on it, which are practically not visible. Therefore, it is very important to make a timely replacement of this part. Therefore, try to control the movement of your car. Carry out a timely inspection of the car. If you find any malfunctions, immediately eliminate them. This will help get rid of the trouble in the future.
