REPAIR PROCEDURE:
WARNING:All pressurized air suspension components contain high pressure air (up
to 220 psig). Use extreme caution when inspecting for leaks. Wear safety
goggles and adequate protective clothing when inspecting or servicing
the air suspension system. A sudden release of air under this amount of
pressure can cause possible serious or fatal injury.

WARNING:Support the vehicle by supplemental means before performing any work
on the air suspension system to prevent the vehicle from changing
height. Before any given component is to be serviced it must be deflated.
Servicing the air suspension system without supplemental support, or
with pressure in the specific component, can cause possible serious or
fatal injury.
CAUTION: When removing an air line from a component and the air line is to be
reused, do not remove the 90° fitting or the brass fitting from the air line.
If either is removed, the air line must be replaced. New components have
air line fittings attached; however if the original air line is used the
original fitting must also be used. Do not remove protective caps or
plugs from air lines or components until ready to install the air line to
prevent moisture or dirt intrusion. All air line fittings must be hand
started to avoid cross threading.
