GM Corsica/Beretta 1988-1996 Repair Guide



The Corsica and Beretta have a semi-independent rear suspension system which consists of an axle with trailing arms and a twisting cross beam, for the Corsica and a tubular trailing arm for the Beretta, 2 coil springs and 2 shock absorbers, 2 upper spring insulators and 2 spring compression bumpers. The axle assembly attaches to the body through a rubber bushing located at the front of each control arm. The brackets are integral with the underbody side rails. A stabilizer bar is available as an option.

Two coil springs are used, each being retained between a seat in the underbody and one on the control arm. A rubber cushion is used to isolate the coil spring upper end from the underbody seat, while the lower end sits on a combination bumper and spring insulator.

The double acting shock absorbers are filled with a calibrated amount of fluid and sealed during production. They are non-adjustable, non-refillable and cannot be disassembled.

A single unit hub and bearing assembly is bolted to both ends of the rear axle assembly; it is a sealed unit and must be replaced if found to be defective.
