Chevrolet Sonic Repair Manual: Rear Suspension Description and Operation
This vehicle has a beam rear suspension system consisting of the following components:
- An axle with integral trailing arms
- A cross beam
- Two coil springs
- Two standard shock absorbers
- Axle Assembly
-
The axle assembly attaches to the underbody through a rubber bushing and bracket located at the front of each integral trailing arm. The brackets are bolted to the underbody side rails. The axle structure itself maintains the geometrical relationship of the wheels relative to the centerline of the body.
Rear camber and tow are not adjustable. Replace any damaged suspension components as necessary.
- Coil Spring
-
The coil springs support the weight of the vehicle in the rear. Rubber insulators isolate the coil spring at the upper and lower spring seat.
- Shock Absorber
-
The shock absorbers are connected to the rear axle and the vehicle underbody. The shock absorbers are non-adjustable and non-refillable. Service of the shocks requires replacement of the shock assembly.
- Wheel Bearing/Hub Assembly
-
A single hub and bearing assembly is bolted to both ends of the rear axle assembly. The hub and bearing assembly is a sealed unit that eliminates the need for wheel bearing adjustment or periodic maintenance.
Although the rear suspension components are lubricated for life and require no routine lubrication, they should be inspected periodically for damage and wear.
