contact with the vehicle without raising
the vehicle.
NOTE: Do not remove an air
compressor tube in an attempt to
depressurize the air suspension.
Always follow the air suspension
depressurization procedure in air
suspension. Failure to follow this
procedure may cause personal
injury or damage to the air
compressor and/or tube fittings.

compressor filter into the frame
rail while removing. Failure to do
so will result in damage to the air
compressor filter.
STEP 4:
Depress both plastic tabs securing the
air compressor filter into the frame rail
during removal.
