Inspection of Automobile Wheel Bearing Inspection of Automobile Wheel Bearing

The most common wheel bearings for cars used in the past were the use of single row tapered roller or ball bearings. With the development of technology, car hub units have been widely used in cars. The use and use of hub bearing units is growing and is now in its third generation. The first generation consisted of double row angular contact bearings. The second generation has a flange for fixing the bearing on the outer raceway, and the bearing can be simply fixed to the axle and fixed by a nut, so that the maintenance of the automobile becomes easy. The third-generation hub bearing unit is equipped with a bearing unit and an anti-lock brake system ABS. The hub unit is designed with an inner flange and an outer flange. The inner flange is bolted to the drive shaft. The outer flange mounts the entire bearing together. Worn or damaged hub bearings or hub units can cause unsuitable and costly failures in your vehicle's travel path and even cause damage to your safety.

1. In order to ensure maximum safety and reliability, it is recommended that you always check the wheel bearings regardless of the length of the car. Pay attention to the bearing's early warning signal of wear, including any frictional noise during rotation or abnormal speed reduction of the suspension combination wheel during cornering. For rear-wheel-drive vehicles, it is recommended that the vehicle travels to 38,000 km to deal with the lubrication of the front hub bearings. When replacing the brake system, check the bearings and replace the oil seal.

2. If you hear the noise from the wheel bearing parts, first of all, it is important to find the location where the noise occurs. There are many moving parts that can produce noise. It is also possible that some of the rotating members are in contact with the non-rotating members. If it is confirmed that the noise is in the bearing, the bearing may be damaged and needs to be replaced.

3. Because the working conditions of the front hubs causing the failure of the bearings on both sides are similar, it is recommended to replace them in pairs even if only one bearing is broken.
