How to determine whether the shock absorber bearing needs to be replaced?

Shock absorber bearing is an important part of the automotive suspension system, responsible for supporting and damping the vibration and turbulence generated by the vehicle during the driving process. With the increase of the use time of the car, the shock absorber bearing may appear wear and aging phenomenon, affecting the shock absorption effect and driving stability. Therefore, timely inspection and replacement of shock absorber bearings is an important measure to ensure driving safety and comfort.

First of all, to understand whether the shock absorber bearing needs to be replaced, you need to pay attention to some common signs and signs, including:

1. Abnormal sound: If you hear the obvious abnormal sound from the shock absorber bearing during driving, it may be that the bearing has a problem and needs to be repaired or replaced in time.

2. Increased vibration: If the vibration sensation is significantly increased when the vehicle is driving, especially when it is more obvious when it is over the hill or driving on an uneven road surface, it may be that the shock absorber bearing has failed.

3. Unstable driving: the failure of the shock absorber bearing will lead to unstable driving of the vehicle, inflexible steering, and even affect driving safety.

4. Abnormal suspension height: the shock absorber bearing is responsible for supporting the body and suspension system. If the suspension height of the vehicle changes abnormally or sinks, the shock absorber bearing may fail.

5. Increased sense of vibration: when driving, the vibration felt by the vehicle chassis becomes obvious and cannot be eliminated in time, which may be that the shock absorber bearing has been aging and failed.

If the above situation is found, it is necessary to check and replace the shock absorber bearing in time. In general, there is no fixed standard for the replacement cycle of shock absorber bearings, which needs to be determined according to the actual condition of the vehicle. In general, it is recommended to check the shock absorber bearing every 100,000 kilometers or so, and decide whether to replace it according to the actual situation.

When checking and replacing the shock absorber bearing, you can determine whether it needs to be replaced by the following steps:

1. Observe the appearance: Check whether the appearance of the shock absorber bearing is deformed, cracked, rusted or leaked oil. If the above situation occurs, the bearing may have failed and needs to be replaced.

2. Measurement size: Measure whether the size of the shock absorber bearing meets the specified standards, if there is a size deviation or deformation, it may be that the bearing has been seriously worn and needs to be replaced.

3. Pressure test: By pressurizing the shock absorber bearing to test its elastic and compression performance, to observe whether it can normally rebound and absorb shock. If the test results are not ideal, it indicates that the bearing may not work properly and needs to be replaced.

4. Rotation test: Rotate the shock absorber bearing to observe whether there is stuck and abnormal sound. If it is found that the rotation is not flexible or there is a significant friction sound, the bearing may need to be replaced.

5. Aging degree: According to the service life and actual condition of the bearing, determine whether it needs to be replaced. In general, the bearing has been used for more than 5 years, and it is recommended to replace it regularly.

It should be noted that when replacing shock absorber bearings, choose original parts or brand products to ensure quality and performance. In addition, after replacement, it is necessary to carry out the dynamic balance and four-wheel positioning of the tire in time to ensure the stability and safety of the vehicle.

In general, the shock absorber bearing is an important part of the automotive suspension system, which affects the driving stability and riding comfort of the vehicle. Therefore, in daily use, it is necessary to pay timely attention to the state of the shock absorber bearing, find problems and deal with them in time to ensure driving safety and comfort. I hope the above content will help you determine whether the shock absorber bearing needs to be replaced.
