What Causes Squeaking Noises from the Car Chassis?
1 Answers
When a car makes squeaking noises while driving on rough roads, it is usually caused by loose suspension components in the chassis. Here are the solutions: 1. If the chassis emits squeaking noises while driving, and the sound comes from the connection between the MacPherson strut and the shock absorber, park the car in a relatively quiet place, turn off the engine, and press down on the four shock absorbers with both hands to rock the car body up and down. Listen carefully during the rocking process to identify the source of the noise. 2. If the sound occurs when turning the steering wheel and is not due to tire friction with the ground, it is likely caused by a damaged outer CV joint. Replacing the outer CV joint can eliminate the noise. If the sound is caused by tire friction with the ground, a four-wheel alignment may be necessary. Squeaking from the rear wheels could originate from the connection between the rear axle and the shock absorber. First, check the screws at the connection point for any looseness.
