The rear suspension is fully independent utilizing rear MacPherson struts at each wheel. If the vehicle is equipped with Programmed Ride Control (PRC), the rear strut towers locate the PRC actuators and the strut assemblies. A forged rear spindle bolts to the shock absorber, double rear lateral links, and a single trailing arm. It is these components and a rear crossmember that make up the rear suspension.
If the vehicle is not equipped with PRC, the struts used are the conventional non-adjustable type and cannot be interchanged with the PRC struts. The PRC actuators will not be on the strut mounting block. Both the lateral links and the trailing arm have rubber bushings at each end. The lateral links are attached to the rear subframe and the spindle with a common bolt and nut assembly at each end. The trailing arm bolts to the shock absorber and a bracket on the floor pan. Never try to straighten a damaged rear suspension component. Always replace with a new part.
Lateral links, trailing arms, and spindles are normally replaced only if damaged. If a suspension part has been damaged, have the underbody dimensions checked. If the underbody dimensions are not correct, the body will have to be straightened before installing new suspension parts.
The rear wheels and brake drum/rotors are supported on a 1-piece, non-serviceable, non-adjustable bearing. The inner race rides on the spindle, which is bolted to the rear strut and control arms. The bearing outer race is press-fit into the hub. A staked nut on the outer side and a retaining ring on the inner side hold the bearing and hub in position on the spindle.
