Front Suspension And Axle

These models (except C 3500HD) have a front suspension consisting of coil springs that are mounted between the spring housings on the frame and the lower control arms. Shock absorbers are mounted inside the coil springs and attached to the lower control arms by bolts and nuts. The upper portion of each shock absorber extends through a frame bracket and is secured with two grommets, two grommet retainers, and a nut.

These models have a front suspension consisting of control arms, stabilizer shaft, shock absorber, and a right and left torsion bar. Torsion bars are used instead of conventional coil springs. The front end of the torsion bar is attached to the lower control arm. The rear of the torsion bar is mounted into an adjustable arm at the torsion bar crossmember. Vehicle trim height is controlled by this arm adjustment.

"K" Series models have sealed front wheel bearings that are pre-adjusted and require no lubrication maintenance. Darkened areas on the bearing assembly are caused by a heat treatment process and do not require bearing replacement.
