Removal

1. Remove the wheel and tire assembly. For additional information, refer to «Section 204-00».

2. Remove the brake disc (1125). For additional information, refer to «Section 206-03».

µ 3. CAUTION:
Do not attempt to remove the hub lock assembly by prying at the hub lock legs. This can result in cracked or broken hub locks, which can cause vacuum leaks.

Install the Hub Removal Clips.

µ 4. Install the Hub Puller.

1 Align the puller with three slots in the hub lock.

2 Tighten the set screw finger-tight.

5. Using the slide hammer remove the hub lock.

µ 6. CAUTION:
Whenever the hub lock is removed the O-ring must be installed new. Failure to do so may allow vacuum leaks causing loss of four wheel drive operations and contamination of the hub lock vacuum system.

Remove and discard the wheel hub O-ring.

µ 7. Remove the brake disc shield (2K005).

l Remove the retaining bolts and the brake disc shield.

µ 8. CAUTION:
The axle shaft retainer ring must be installed new every time it is removed from the axle shaft. Failure to do so can cause damage to the wheel hub or the axle shaft.

Note:
Pull inward on the constant velocity joint outer shaft to aid in removal of the retainer ring.

Using a suitable pair of snap ring pliers remove the axle shaft retainer ring.

µ 9. Disconnect the vacuum hose and, if equipped, the ABS harness electrical connector.

µ 10. Disconnect the vacuum hose and, if equipped, four ABS harness retainers from the frame.

µ 11. Remove the tie-rod end castellated nut.

1 Remove and discard the cotter pin.

2 Remove the castellated nut.

µ 12. Using the special tool, disconnect the tie-rod end.

µ 13. Remove the three wheel hub and bearing mounting bolts.

µ 14. CAUTION:
If any dirt, metal shavings, moisture or corrosion is found in the hub or the hub bore in the knuckle, a new hub lock vacuum valve must be installed. For additional information, refer to «Vacuum Valve—Hub Lock» in this section.

CAUTION:
The wheel hub and bearing are not repairable. The bearing preload cannot be readjusted. If the bearing retaining nut on the wheel hub and bearing is removed, a new wheel hub and bearing must be installed.

CAUTION:
Do not allow the axle shaft to rest on the knuckle main seal. Failure to follow these instructions can damage the main seal.

Note:
The wheel hub and bearing is a slip-fit design and should not require a puller tool for removal.

Remove the wheel hub and bearing. Carefully pull the axle shaft out of the knuckle. Secure the axle shaft with mechanic's wire.

µ 15. CAUTION:
Whenever the wheel hub is removed the O-ring must be installed new. Failure to do so can allow vacuum leaks causing loss of four wheel drive operations and contamination of the hub lock vacuum system.

Remove the bearing/knuckle O-ring.

µ 16. CAUTION:
The thrust washer must never be reused. Install a new thrust washer whenever it is removed. Failure to do so can cause damage to the wheel hub and the axle shaft.

CAUTION:
Never loosen or remove the large nut on the wheel hub and bearing. The bearing preload is factory preset and is not adjustable. The wheel hub and bearing cannot be greased or repacked. Removal of the large nut can cause loss of wheel bearing preload and severe damage to the wheel hub and bearing.

Remove the thrust washer.

µ 17. Remove the needle bearing set.

1 Install the Bearing Cup Puller.

2 Install the Impact Slide Hammer.

3 Remove the caged needle bearing.

18. CAUTION:
The wheel hub is not repairable. Any attempt to repair the wheel hub can cause severe damage to the vehicle's suspension/front drive axle, loss of four wheel drive operations and wheel end contamination.

CAUTION:
If the wheel hub has excessive metal particles present in the axle shaft bore area the vehicle's vacuum system must be flushed out and tested for correct operation. Failure to do so will cause severe damage to the wheel end seals, hub lock vacuum valve and the vehicle's vacuum system.

CAUTION:
The wheel hub and bearing is not serviceable. The bearing preload cannot be readjusted. If the bearing retaining nut on the wheel hub and bearing is removed, the wheel hub and bearing must be installed new.

Note:
Inspect the bearing preload nut and bore slots to ensure that the slots are aligned. If the slots are not aligned or the slots are damaged, install a new wheel hub and bearing.

Clean and inspect the wheel hub.

l Inspect the axle shaft bore for scoring and excessive wear.

l Inspect the needle bearing bore for scoring, blueing and excessive wear.

l Inspect the wheel hub sealed bearing for excessive looseness or binding.
