Wheel Bearing and Wheel Hub:

Removal and Installation

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. For additional information, refer to Maintenance/Service and Repair.

3. CAUTION: Do not allow the caliper and anchor plate 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.
^ To install, tighten to 160 Nm (118 ft. lbs).
4. Remove the brake disc.
5. Peel back the rubber splash shield and disconnect the wheel speed sensor electrical connector.





6. Remove the bolts and the wheel bearing and hub assembly.
^ To install, tighten to 120 Nm (89 ft. lbs).

7. CAUTION: To avoid sensor or wiring damage, be sure to properly route the wheel speed sensor wiring in front of the stabilizer bar link.

NOTE: During reassembly, verify that the wheel speed sensor electrical connector is fully seated with an audible click, and that the rubber splash shield is positioned back into place.

To install, reverse the removal procedure.
