Suspension: Description and Operation

DESCRIPTION





The rear suspension system on the 1500 series is a coil spring system, while the 2500 and 3500 series is a leaf spring system. The suspension systems are comprised of:

- Shock Absorbers (7)
- Jounce Bumpers (3)
- Stabilizer Bar (9) (1500 series)
- Stabilizer links (1) (1500 series)
- Coil Springs (2) (1500 series)
- Upper Control Arms (above lower control arms, not shown) (1500 series)
- Lower Control Arms (6) (1500 series)
- Track Bar (5) (1500 series)
- Leaf Springs (2500 and 3500 series, not shown)
- Auxiliary Leaf Spring (3500 series, not shown)
- Auxiliary Spring Bumpers (3500 series, not shown)
- Leaf Spring Eye Bushings (2500 and 3500 series, not shown)
- Leaf Spring Tip Inserts (2500 and 3500 series, not shown)

CAUTION: A vehicle should always be loaded so the vehicle weight center-line is located immediately forward of the rear axle. Correct vehicle loading provides proper front tire-to-road contact. This results in maximum vehicle handling stability and safety. Incorrect vehicle weight distribution can cause excessive tire tread wear, spring fatigue or failure, and erratic steering.

CAUTION: Suspension components with rubber/urethane bushings (except stabilizer bar) should be tightened with the vehicle at normal ride height. It is important to have the springs supporting the weight of the vehicle when the fasteners are torqued. If springs are not at their normal ride position, vehicle ride comfort could be affected and premature bushing wear may occur.
