Air Spring
After the front air spring is deflated, the pressure relief valve will still hold some pressure in the front air spring/shock assembly. If pressure relief valve removal is necessary, the vehicle must be hoisted with all four wheels off the ground, then the pressure relief valve must be slowly removed to allow residual pressure to vent. If the vehicle is not hoisted, the suspension could lower, causing injury.
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.
Before performing any service on the air suspension system, the system must be disabled to prevent the system from changing ride height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without the system disabled, or with pressure in any specific component, can cause possible serious or fatal injury.
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.
The air spring and shock are integral to the air spring and are not serviceable separately.
For removal and installation of the air spring and shock assembly. Refer to SHOCK ABSORBER, SUSPENSION, REMOVAL AND INSTALLATION .
