First of all, the first sign that the dust cover kit of the shock absorber needs to be replaced is that it is damaged or aging. Because the dust jacket of shock absorber is exposed to the external environment for a long time and is affected by various vibrations and impact forces, it is easy to be damaged or aged. Once the dust cover kit of the shock absorber is damaged or aged, foreign impurities will enter the shock absorber and affect its normal operation. Therefore, when it is found that the dust jacket of shock absorber is damaged or aged, it needs to be replaced in time.
Secondly, the second sign that the dust cover kit of shock absorber needs to be replaced is oil leakage. The main function of the dust-proof sleeve of the shock absorber is to prevent dust and water vapor from entering the shock absorber and protect the sealing performance of the shock absorber. If there is oil leakage in the dust jacket of the shock absorber, it will lead to the leakage of lubricating oil inside the shock absorber and affect the normal work of the shock absorber. Therefore, when oil leakage is found in the dust jacket of shock absorber, it needs to be replaced in time.
In addition, the dust cover of the shock absorber needs to be inspected and replaced regularly according to the automobile use environment and mileage. When driving in bad road conditions or often on muddy roads, the dust cover of shock absorber is easily damaged and needs to be inspected and replaced more frequently. At the same time, after a certain mileage, it is also necessary to regularly check and replace the dust cover of the shock absorber to ensure the normal work of the shock absorber.
