Spring, Air Suspension: Description: Description
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.
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.
Standard suspension systems have a rear coil spring. If equipped with air suspension an air suspension spring replaces the conventional rear coil spring and is an air spring without any metal coil at all. Any time a new or compressed air spring is installed, a short fill routine must be preformed with a scan tool, then the air bag must be inspected for proper alignment. Only after this check can a complete fill routine be done. For removal and installation of the air springs, refer to SPRING(S), REMOVAL .
