The rear suspension is fully independent and consists of a crossmember with 4 parallel links, 2 trailing links, 2 strut assemblies with coil springs and insulators, and 2 knuckles containing the hub and bearing assemblies. The strut assemblies support the weight of the vehicle using coil springs positioned around the strut dampeners. The coil springs are seated on insulators attached to the upper mount and the lower spring seat of the strut assembly. The parallel links and the trailing link bracket have rubber isolator bushings at each end and are attached to the crossmember and the knuckle. The rear parallel link is attached to the crossmember through adjustment cams that are used to adjust rear toe. The trailing links are attached to the body, through the trailing link bracket, and the bottom of the knuckle. A forged knuckle bolts to each strut assembly. Lateral movement of the knuckle is controlled by the parallel links. Fore and aft movement of the knuckle is controlled by the trailing link.
