Replacing an air sleeve safely
A replacement air sleeve is the part that holds air and carries load in a rear air suspension. Over time it can crack, chafe or lose pressure, which causes the rear to sag and ride harshly. Replacing the sleeve restores the rear’s support, but the fit and mounting should match the vehicle before the old part is removed.
Work carefully with pressurized parts. Support the vehicle on stands, release air pressure before loosening fittings, and keep hands clear of the bag while it is moving. After installation, check fittings for leaks, confirm the bag sits straight, and recheck the ride height once the system has settled.
- Look for cracks, bulges or rubbing
- Check the jounce bumper alongside the sleeve
- Test for leaks at each fitting
