Rear Suspension: Description

The Aerostar rear suspension is a coil spring type system. See Fig 1 . It supports and links the rear axle to the frame with one rear suspension arm and bushing and two lower control arms.

• The two coil springs are of the variable rate, wire type.
• The upper spring coils are designed to contact each other when the vehicle is loaded.
• The small diameter upper spring is installed in the insulator on the frame.
• Both springs are matched in regard to the load capacity and rate.
• If one spring is replaced, the replacement spring must match the capacity of the other spring.
