Upper Control Arm
UPPER CONTROL ARM
DESCRIPTION
The upper control arm is a high strength steel stamping. The upper control arm uses the 2 rubber bushings of the upper control arm/shock absorber
mounting bracket to isolate it from the mounting bracket and the body of the vehicle. The upper control arm is bolted to the top of the steering knuckle
through the upper ball joint.
If damaged, the upper control arm is serviced only as a complete component. Inspect the upper control arm for any signs of damage. If control arm
shows any sign of damage the upper control arm must be replaced. Do not attempt to repair or straighten a broken or bent upper control arm.
The only serviceable component of the upper control arm is the ball joint grease seal. No other repair or replacement procedure should be attempted
on any component of the upper control arm. Service procedures to replace the serviceable components are detailed in the specific component.
OPERATION
The upper control arm supports the upper end of the steering knuckle and allows for the up and down movement of the suspension during the jounce
and rebound travel.
Lower Control Arm
LOWER CONTROL ARM
DESCRIPTION
The lower control arm is a ductile iron casting using 2 rubber bushings to isolate it from the front suspension crossmember and body 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 the front suspension crossmember using a through-bolt. The lower control arms are inter-connected
through a linked rubber isolated sway bar.
OPERATION
The lower control arm supports the lower end of the steering knuckle and allows for the up and down movement of the suspension during the jounce
and rebound travel. It also provides a lower mounting point for the shock assembly.
