 Overnight leak down test — Recheck air pressure after the vehicle has been used for
24 hours. If the pressure has dropped more than 5 PSI, then there is a leak that must
be fixed. Either fix the leak yourself or return to the installer for service.
 Air pressure requirements — Regardless of load, the air pressure should always be
adjusted to maintain adequate ride height at all times while driving.
 Thirty day or 500 mile test — Recheck the air spring system after 30 days or 500 miles,
whichever comes first. If any part shows signs of rubbing or abrasion, the source should be
identified and moved, if possible. If it is not possible to relocate the cause of the abrasion,
the air spring may need to be remounted. If professionally installed, the installer should
be consulted. Check all fasteners for tightness.
