Control Arm: Testing and Inspection

DIAGNOSIS AND TESTING - LOWER CONTROL ARM

Inspect the lower control arm for signs of damage from contact with the ground or road debris. If the lower control arm shows any sign of damage, look for distortion. Do not attempt to repair or straighten a broken or bent lower control arm. If damaged, the lower control arm stamping is serviced only as a complete component.

Inspect both lower control arm isolator bushings for severe deterioration and replace the lower control arm as required. Inspect the ball joint per the inspection procedure and replace the lower control arm required.

The only serviceable component of the lower control arm is the ball joint seal boot. It should only be replaced if damaged during service of a chassis component. Otherwise, replace the entire control arm.
