Raise and support vehicle at a safe and comfortable working height. 2. Support the axle then remove coil spring and shock. Refer to service manual for proper disassembly procedure. Installing one side at a time will make the installation easier. 3. Apply thread sealant to a 90 degree air fitting and screw it into the top of the air spring. 4. Screw the mounting pin into top of the air spring. 5. Place the 4” diameter washer on top of the frame, above the coil spring pocket. Raise the air spring up to the spring pocket with the pin sticking through the washer. Secure with the large cotter key. 6. Place the large lower air spring plate over the lower coil spring retainer. 7. Pull the piston down out of the air spring and seat it on the lower coil spring retainer. The center hub in the piston should fit inside the retainer. 8. Some retainers may require trimming to allow the air spring piston to slide into the retainer. 9. Secure the air spring to the axle using a 3/8” x 1” bolt, lock washer, flat washer, and the 2 ½” washer. 10. Inflate the air spring and check air spring clearance. If the spring is allowed to rub on anything it will cause failure, this is not a warrantable situation. 14. This system will retain the factory bump stop. 15.
