Removal

CAUTION: Suspension fasteners are critical parts because they effect performance of vital components and systems and their failure can 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: The electrical power to the air suspension system must be turned off prior to hoisting, jacking or towing an air suspension vehicle. 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.

Turn the air suspension service switch to the OFF position.
2. With the vehicle in NEUTRAL, position it on a hoist.

3. CAUTION: Do not allow the caliper and anchor plate assembly to hang from the brake hose or damage to the hose can occur.

Remove the bolts and position the caliper and anchor plate assembly aside.
^ Support the caliper and anchor plate assembly using mechanic's wire.
4. Remove the brake disc.

5. NOTE: Make sure that the wheel stud being removed is positioned near the access hole on the wheel knuckle prior to installing the special tool.





Using the special tool, press the wheel stud out of the wheel hub flange.





6. Remove the wheel stud.
