Special Tool(s):

Removal

CAUTION: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure can result in major service expense. New fasteners with the same part number or an equivalent part must be installed if installation is 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.

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 brake caliper and anchor plate assembly to hang from the brake hose or damage to the hose can occur.

Remove the bolts and position the brake caliper aside.
^ Support the caliper and anchor plate assembly using mechanic's wire.
^ To install, tighten to 27 Nm (20 ft. lbs.)
4. Remove the spring and the actuator from the rear parking brake shoes.





5. Using the special tool, press the wheel stud from its seat.





6. Rotate the flange so that the tip of the wheel stud is pointing upwards and remove the wheel stud.
^ Discard the wheel stud.

Installation

CAUTION: Never use air tools to install wheel studs. The serrations can be stripped from the stud.





1. Insert a new wheel stud in the hole in the axle flange, making sure the serrations are aligned with those made by the original wheel stud.





2. Place 4 flat washers over the outside end of the wheel stud, and thread a standard wheel nut with the flat side against the washers.
3. Tighten the wheel nut until the wheel stud head seats against the back side of the axle flange.
4. Remove the wheel nut and washers.
5. Position the brake disc and caliper and install the bolts.
^ Tighten to 27 Nm (20 ft. lbs.).
6. Turn the air suspension service switch to the ON position.
