Part 1 Of 2:

Part 2 Of 2:

There is one lower control arm on each side of the vehicle. Each lower control arm is a stamped steel unit using rubber isolated pivot bushings to isolate it from the front suspension crossmember and frame of the vehicle. The rear bushing can be serviced separately.
The front of the lower control arm is bolted to the front crossmember using a bolt through the center of the rubber pivot bushing. The rear of the lower control arm is mounted to both the front crossmember and the frame rail of the vehicle using a thru-bolt. The thru-bolt goes through both the crossmember and rear lower control arm bushing, threading directly into the frame rail of the vehicle.
The left and right lower control arms are interconnected through a linked rubber isolated stabilizer bar.
The outboard end of each lower control arm connects to the steering knuckle using a ball joint.
