Control Arm: Description and Operation

The lower control arm is a ductile iron casting using 2 rubber bushings to isolate it from the front suspension crossmember and frame of the vehicle. The isolator bushings consist of 2 metal encased rubber isolated pivot bushings. 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 lower control arms are inter-connected through a linked rubber isolated stabilizer bar.
