A MacPherson strut type rear suspension is used on all Saturn vehicles. The strut contains an internal damper, much like a conventional shock absorber. Therefore, strut assemblies consisting of a strut and a coil spring provide both spring and shock absorber functions. If the strut becomes damaged or worn, it must be replaced as a unit since it is not serviceable.
The strut assembly is connected to the vehicle at three locations. The top of the strut is fastened to the vehicle body by fasteners. The bottom of the strut is attached to the crossmember through the knuckle and lateral links, providing side-to-side stability, and to the vehicle body through a trailing arm, providing front-to-rear stability.
Although the rear suspension components are lubricated for life and require no routine lubrication, they should be inspected periodically for damage and wear.
