C 2500 Truck 2WD V8-5.7L VIN R (1997)
Control Arm: Description and Operation
The inner ends of the lower control arm have pressed-in bushings. Bolts, passing through the bushings, attach the arm to the frame. The lower ball joint
assembly is a press fit in the lower control arm and attaches to the steering knuckle with a castellated nut and cotter pin.
Rubber grease seals are provided at ball socket assemblies to keep dirt and moisture from entering the joint and damaging bearing surfaces. Also, all ball
joints have grease fittings for routine maintenance.
