What is the Control Arm Assembly all about?
March 16, 2016
A control arm set (lower and upper) connects the front suspension of the car to the frame of the car. It is connected to the wheels through ball joints, and to the frame of the car through bushings. It is usually found on the front side of the car. (Few cars have control arms in the back.) If the control arm is bent (can happen when you are in an accident or go over a large pothole), or the bushings wear out, you may have to replace the control arm assembly. It is a good idea to replace the bushings and the ball joints while doing this service.
How it's done:
- Verify that the control arm or bushings are faulty.
- Remove the control arm.
- Install the new control arm assembly
- Inspect the suspension system for any other worn or damaged components.
- Test drive the vehicle
