Lower Control Arm

WARNING: This page is about a different car, the 2006 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

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.

The serviceable components of the lower control arm are: the ball joint, the ball joint grease seal and the lower control arm rear isolator bushing. The front isolator bushing is not replaceable. If the front isolator bushing needs to be replaced, the entire lower control arm must be replaced.

Inspect both lower control arm isolator bushings for severe deterioration and replace lower control arm or rear bushing as required. Inspect the ball joint per the inspection procedure and replace as required. (Refer to SUSPENSION/FRONT/LOWER BALL JOINT - DIAGNOSIS AND TESTING) .
