A ball joint is located on the bottom of the knuckle which attaches to the lower control arm. The knuckle also has two machined, drilled legs on the leading end casting to support and align the front disc brake caliper adapter.

Diagnosis and Testing

KNUCKLE

The front suspension knuckle is not a repairable component of the front suspension. It must be replaced if found to be damaged in any way. If it is determined that the knuckle is bent when servicing the vehicle, no attempt is to be made to straighten the knuckle.

Inspect the lower ball joint per the inspection procedure in this Service Information . The lower ball joint can be replaced separately from the knuckle.
