Subaru Coupes/Sedans/Wagons 1985-1996 Repair Guide

Pneumatic Strut Suspension


This air suspension system is used on all 4WD models except the Justy. The air suspension system is virtually identical to the standard strut type suspension, except that the coil springs are replaced by air springs.The addition of the air springs allows the vehicle ride to be adjusted by the operator, and it allows the suspension height to be maintained when the vehicle is loaded. Each of the air springs has a ride height sensor attached, that allows the height to be monitored individually at each wheel. A compressor distributes air to each of the air springs as it is needed.

A further description of the operation of, and repair of the pneumatic suspension can be found later in this section.
