Replacement Considerations

The following rear suspension components may be replaced individually:
^ Air compressor (less drier), regenerative compressor air drier and O-ring are all serviced as separate components.
^ Air suspension height sensor, control module and air suspension switch are replaceable.
^ Rear springs are replaceable as assemblies (includes solenoid valves). It is not necessary to replace in pairs.
^ Air spring solenoid valves and external solenoid of-rings are replaceable.
^ Air lines are replaceable. However, quick connect unions and bulk tubing are available to mend a damaged air line.
^ The collet and O-ring of quick connect fittings are replaceable with air spring connector repair kit.
^ Gas-filled shock absorbers must be replaced as assemblies. They are not serviceable. Replace only the damaged shock absorber. It is not necessary to replace in pairs.
^ Rear suspension lower arms, including both end bushings, are replaceable as assemblies. They must be replaced in pairs.
^ Rear suspension arm and bushings, including body end bushing, are replaceable as assemblies. They must be replaced in pairs.
^ Rear stabilizer bar is replaceable with stabilizer bar-to-axle stabilizer bar link included.
