The front suspension on rear wheel drive models is a short/long arm suspension system with helical coil springs. It consists of spindles, steering knuckles, upper and lower control arms with integral ball joints and bushings, adjustment shims, coil springs, shock absorbers and a stabilizer bar. The springs are computer-selected based on vehicle options.
The critical joint in the front chassis area includes the front crossmember, longitudinal side member, and upper control arm. Whenever this joint is loosened or removed (including engine service) it is imperative that new fasteners or cleaned and lubricated present fasteners be installed with the proper installation torque at this critical joint.
