Removal and Installation
WARNING: The electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle.
This can be accomplished by turning off the air suspension switch located in the LH rear quarter trim panel.
Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these
operations. Failure to follow these instructions may result in personal injury.
CAUTION: Suspension fasteners are critical parts because they affect performance of vital parts and systems and their failure can result in major
service expense. A new part with the same part number must be installed if installation becomes necessary. Do not use a replacement 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.
