Control Arm: Description and Operation

LOWER CONTROL ARM
The lower control arm is a steel forging with 2 rubber bushings isolating the lower control arm from the front cradle assembly. The isolator bushings consist of a metal encased pivot bushing and a solid rubber tension strut bushing. The lower control arm is bolted to the cradle assembly using a pivot bolt through the center of the rubber pivot bushing and at the tension strut isolator bushing.

The ball joint is an integral part of the control arm and has a non-tapered stud with a notch for clamp bolt clearance. The stud is clamped and locked into the steering knuckle leg with a clamp bolt. The ball joint used on this vehicle is non-serviceable and if defective must be serviced as part of the lower control arm.
