汽車的底盤出現異響是因為底盤上的橡膠襯套出現了老化的現象。底盤的橡膠襯套老化后會導致底盤上的很多部件曠量變大，這樣會導致汽車經過顛簸路面時出現異響，解決這個問題只需要更換老化的底盤襯套就可以了。

The abnormal noise on the car chassis is due to the aging of the rubber lining on the chassis.

If the rubber lining ages, it will cause abnormal chassis noise, which will affect the driving quality and handling of the car.

如果橡膠襯套老化了，需要及時更換。有些汽車控制臂上的橡膠襯套是無法單獨拆卸更換的，這種汽車需要直接更換新的控制臂。在汽車上是有很多橡膠制品的，這些橡膠制品長時間使用都會出現老化現象，所以汽車上的橡膠制品是需要定期更換的。汽車上的橡膠部件有輪胎，密封膠條，皮帶，底盤襯套等。

If the rubber lining ages, it needs to be replaced in a timely manner.
