Control arms often don’t fail on their own, although their associated bushings can break or wear causing a clunk noise when your Lexus LS 400 goes over bumps or changes speed rapidly—whether braking or under hard acceleration.

Control arm bushes stabilize the movement of the arms to ensure the correct geometry is maintained in all situations.
Worn or rubber bushes in these locations lead to dynamic changes in wheel alignment that effect the handling of a vehicle as well as the tyre life.
SuperPro Bushings solve this issue and are the perfect repair or repair upgrade solution.
