All vehicles 

CAUTION: Do not allow the caliper to hang from the brake hose or damage to the hose can occur.
6. Remove the 2 brake caliper anchor plate bolts and position the brake caliper aside.
   • Support the brake caliper using mechanic's wire.
NOTE: If excessive force must be used during brake disc removal, the brake disc should be checked for lateral runout prior to installation. For additional information, refer to BRAKE SYSTEM - GENERAL INFORMATION .
7. Index-mark and remove the brake disc.
CAUTION: The service replacement kit includes 2 O-ring seals; one for testing the hub lock assembly and one for reassembly into the wheel hub. DO NOT REUSE O-RING SEALS or hub lock failure may occur.
NOTE: Due to the fit of the splines, the hub lock 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 hub lock.
NOTE: Always check the vacuum leak rate of the wheel end assembly when repairing or diagnosing the axle, wheel end or hub lock performance.
8. Remove the hub lock.
   • Loosen each screw 1-to-2 turns.
   • Gently pry on the hub lock cap edge to release gasket adhesion.
   • Remove and discard the screws.
   • While lifting/jiggling the axle U-joint, pull or uniformly pry the hub lock from the wheel bearing and wheel hub.
9. Remove the axle shaft snap ring.
NOTE: The wheel bearing and wheel hub assembly is a slip-fit design and should not require a puller to remove it.
10. Remove and discard the 4 wheel hub nuts and the wheel hub.
11. If necessary, remove the brake disc shield.
