Upper Control Arm

UPPER CONTROL ARM

DESCRIPTION
The upper control arm is a high strength steel stamping. The upper control arm uses the 2 rubber bushings of the upper control arm/shock absorber mounting bracket to isolate it from the mounting bracket and the body of the vehicle. The upper control arm is bolted to the top of the steering knuckle through the upper ball joint.

If damaged, the upper control arm is serviced only as a complete component. Inspect the upper control arm for any signs of damage. If control arm shows any sign of damage the upper control arm must be replaced. Do not attempt to repair or straighten a broken or bent upper control arm.

OPERATION
The upper control arm supports the upper end of the steering knuckle and allows for the up and down movement of the suspension during the jounce and rebound travel.
