4. Remove the wheel speed sensor harness-to-wheel knuckle bolt.

5. Remove and discard the 8 wheel extension nuts and the wheel extension.

   All vehicles 

6. NOTE: Do not allow the caliper to hang from the brake hose or damage to the hose can occur.

   Remove the 2 brake caliper anchor plate bolts and position the brake caliper aside.

   • Support the brake caliper using mechanic's wire.
7. Index-mark and remove the brake disc.
8. NOTE: The service replacement kit includes 2 O-ring seals; one for testing the hublock assembly and one for reassembly into the wheel hub. DO NOT REUSE O-RING SEALS or hublock failure may occur.
   NOTE: Due to the fit of the splines, the hublock will be difficult to remove. Lifting or lightly prying (with a small bar) on the axle U-joint will ease removal. When prying on the cap/hub flange, work around the flange to uniformly withdraw the hublock.
   NOTE: Always check the vacuum leak rate of the wheel end assembly when repairing or diagnosing the axle, wheel end or hublock performance.

   Remove the hublock.

   • Loosen each screw 1 to 2 turns.
   • Gently pry on the hublock cap edge to release gasket adhesion.
   • Remove and discard the screws.
   • While lifting/jiggling the axle U-joint, pull or uniformly pry the hublock from the wheel bearing and wheel hub.
9. Remove the axle shaft snap ring.
10. NOTE: The wheel bearing and wheel hub assembly is a slip-fit design and should not require a puller to remove it.

    Remove the 4 wheel hub nuts and the wheel hub.

    • Discard the nuts.
11. If necessary, remove the brake disc shield.

    Vehicles with ABS 

12. Remove the wheel speed sensor bolt and position the sensor aside.
