AIR SPRINGS (REAR)
WARNING:When installing air spring, DO NOT allow vehicle to be supported by an unpressurized air spring. When pressurizing EAS system, air spring and shock absorber must be properly installed. Unrestricted movement of a pressurized air spring will result in failure of the assembly, causing component damage and possible personal injury.
NOTE:A failed air spring cannot be repaired. DO NOT try to dismantle or overhaul air spring.
Removal
Raise and support vehicle. See JACKING & HOISTING. Support chassis under rear crossmember. Remove wheelwell liner. Depressurize EAS system. See DEPRESSURIZING & PRESSURIZING EAS SYSTEM. Using a hooked tool, remove air spring upper "J" clip (located between vehicle body and chassis). Remove lower "J" clip (located between air spring and axle). Using a jack and safety stands, raise and support chassis to gain clearance to air spring. Remove air spring. Thoroughly clean air line connection at air spring, disconnect air line and seal exposed ends.
Installation
Ensure mating surfaces of axle, chassis, and air spring are clean. Connect air line to air spring, and ensure air line is correctly routed. With assistance, install air spring upper "J" clip. Remove support from chassis, and lower air spring onto axle. Install "J" clip. Pressurize EAS system and leak test. See EAS SYSTEM LEAK TESTING & REPAIR under ADJUSTMENTS & INSPECTION. To complete installation, reverse removal procedure.
