This procedure should also be used to remove the front air spring.

.

Remove the front shock absorber and air spring assembly.

.

:   If no leak is detected, investigate other areas of the air suspension for faults. Check the assembly for leaks.   Inflate the module to 4 bar and check for pressure loss using leak detector spray.   If a leak is suspected, immerse the shock absorber and air spring assembly in a tank of water to locate the source of the leak and mark the area.

.

Remove the nylon retaining pin.

.

Using the special tool, remove the nut.

.

Remove the rebound washer.

.

: Make sure protective jaws are installed to the vice. Failure to follow this instruction may result in damage to the component.   : Do not clamp the shock absorber tube. Failure to follow this instruction may result in damage to the component. Position the front shock absorber and air spring assembly in a vice.

.

Remove and discard the 3 spacers and 2 O-ring seals.

.

Remove the air spring.   Using a soft faced mallet, gently tap the sleeve support upwards to release it from the O-ring seals.

.

:   Note the fitted position. Remove the bump plate and spring aid.

.

Remove and discard the 2 large black O-ring seals from the lower seal carrier.

.

Remove the front shock absorber and air spring assembly from the vice.

.

: Make sure protective jaws are installed to the vice. Failure to follow this instruction may result in damage to the component.   : Do not clamp the shock absorber tube. Failure to follow this instruction may result in damage to the component. Position the front shock absorber and air spring assembly in a vice.

.

: Use compressed air and lint free non-flocking material. Clean the components.

.

Lift the seal carrier to expose the O-ring seal stack.   Make sure that the damper body O-ring seals and spacers are fully seated to the spring seat.

.

: Take care not to damage the O-ring seals during installation. Install new O-ring seals to the seal carrier.   Apply loctite 8021 (silicon-based oil) to the O-ring seals.

.

:   Make sure that these components are installed to the noted removal position. Install the bump plate and spring aid.

.

Install the air spring.   Align the sleeve support with the first O-ring seal making sure that the location tag is correctly aligned with the spring seat cut-out.

.

: Make sure that the threads of the front air shock absorber are covered with protective tape.   : Take care not to damage the O-ring seals during installation. Install the components in the following order:   1) O-ring seal   2) Spacer   3) O-ring seal   4) Spacer   5) Spacer

.

:   The "T5" stamp on the upper face of the rebound washer must be visable after assembly. Install the rebound washer.

.

Install a new nut and using the special tool, and tighten to 98 Nm (72 lb.ft).

.

: The air supply must be free of any moisture.   : If during disassembly the air sleeve is unrolled, the air sleeve may inflate incorrectly (to one side). If this occurs, release the air pressure, and insert a suitable tool that will not damage the air sleeve or piston (a screw driver handle), into the side opposite the bulge. Inflate and deflate until the air sleeve inflates correctly (the air sleeve will be uniform inside the shroud). :   To prevent damage when seating the sleeve support over the large black O-rings, compressed air should be used to inflate the air spring. Using the special tool coupled to a tire inflator with a gauge, apply approximately 2 bar of air pressure to the air spring to fully seat the sleeve support over the O-ring seals.

.

Check the assembly for leaks.   Inflate the module to 4 bar and check for pressure loss using leak detector spray.   If a leak is suspected, immerse the shock absorber and air spring assembly in a tank of water to locate the source of the leak.

.

Depressurize and remove the special tool from the shock absorber and air spring assembly.

.

Install the nylon retaining pin.

.

:   Install a new air spring pipe connector. Install the front shock absorber and air spring assembly.
