[Marlene]

Due to loose screws connecting chassis components or abnormal noises from shock absorbers, the chassis may squeak when going over bumpy roads. Possible causes of abnormal noises when the car is bumpy: Prolonged driving and turning can cause excessive wear inside the ball joint, resulting in excessive clearance and abnormal noises. The function of the lower control arm is to support the tire, so how can it cause abnormal noises? The lower control arm has two positions with rubber pads, and another position is where the ball joint is installed, mounted on the steering knuckle. Prolonged driving and steering can cause wear on the ball joint and rubber pads, leading to excessive clearance and abnormal noises when driving on uneven roads. Methods to solve abnormal noises when the car is bumpy: The solution is to replace new parts and install a new control arm, which can directly resolve the issue of abnormal noises.
