It is not normal for a new Mercedes-Benz A200 to make abnormal noises inside the car when driving on bumpy roads. Lower control arm causing abnormal noises when the car is bumpy: Lower control arm: The function of the lower control arm is to support the tires. The lower control arm has rubber bushings at two positions, and another position is where a small ball joint is installed, mounted on the steering knuckle. Prolonged driving and steering can cause wear on the small ball joint and rubber bushings, leading to excessive gaps and abnormal noises when driving on uneven roads. Stabilizer bar ball joint causing abnormal noises when the car is bumpy: The function of the stabilizer bar ball joint is to maintain the stability of the car during driving. For example, when the horizontal heights of the left and right wheels are different, to prevent twisting of the bar, the stabilizer bar generates anti-roll resistance to inhibit body roll. Prolonged driving and turning can cause excessive wear inside the small ball joint, resulting in excessive gaps and abnormal noises. The solution is to replace the new parts, which can directly solve the problem of abnormal noises.
