Air Suspension Compressor

Air Suspension Compressor:

Removal and Installation

CAUTION: Suspension fasteners are critical parts because they effect performance of vital components and systems and their failure may result in major service expense. A new part with the same part number or an equivalent part must be installed, if installation is necessary. Do not use a part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

1. WARNING: Shut off the electrical power to the air suspension system prior to hoisting or jacking an air suspension equipped vehicle. Failure to do so may result in unexpected inflation or deflation of the air springs, which may result in shifting of the vehicle during these operations. Failure to follow this instruction may result in serious personal injury.

Turn the air suspension service switch to the OFF position.
