Installation

1. Note:
The cage needle bearings set must be installed into the wheel hub and bearing with the stamped part number portion of the bearing race facing upward.

Coat the needle bearings with Ford High Temperature Wheel Bearing Grease E8TZ-19590-A meeting Ford specification ESA-M1C198-A then insert the needle bearing set into the wheel hub.

µ 2. Install the needle bearing set.

1 Position the Needle Bearing Replacer onto the needle bearings.

2 Install the Driver Handle into the installation tool.

3 Using a hammer, tap on the Driver Handle until the Needle Bearing Replacer seats against the wheel hub and bearing.

µ 3. Verify that the needle bearing set is seated into the wheel hub and bearing.

l Measure the depth between the face of the wheel hub and bearing and the face of the needle bearing set.

µ 4. CAUTION:
Make sure that all eight locking tabs are seated into the groove in the wheel hub and bearing. Failure to do so can cause the thrust washer to come free from the wheel hub and bearing, allowing the bearing preload nut to back off, causing wheel hub bearing failure.

Install a new thrust washer.

1 Coat the needle bearings with Ford High Temperature Wheel Bearing Grease E8TZ-19590-A meeting Ford specification ESA-M1C198-A.

2 Install the new thrust washer.

µ 5. Clean and inspect the knuckle main seal for wear or damage. If the seal is not worn or damaged, proceed to step 12. If a new seal must be installed, follow steps 6 through 11.

6. Note:
The knuckle main seal should only be removed from the knuckle if it is damaged or failed the leak test. The main seal cannot be reused once it has been removed from the knuckle.

Using a drift and a hammer, remove the main seal from the knuckle.

µ 7. Thoroughly clean the knuckle's main seal bore.

1 Clean the main seal bore.

2 Using the shop air supply, thoroughly flush the vacuum hose and the knuckle vacuum chambers.

8. Inspect the knuckle main seal bore for any damage, nicks, burrs or pitting.

9. Apply a thin coat of Ford High Temperature Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A to the bore of the knuckle.

µ 10. Install the main seal.

1 Position the main seal into the special tool, then install the tools on the knuckle.

2 Using the special tools, install the seal until it seats against the knuckle.

11. Remove the special tools.

12. CAUTION:
Apply at least 3 grams of grease to the sealing surface of the main seal. Failure to do so can cause premature failure of the main seal, resulting in damage to the axle shaft or wheel knuckle, or loss of four-wheel-drive.

Apply a generous coat (3 grams or more) of Ford High Temperature Wheel Bearing Grease E8TZ-15950-A or equivalent meeting Ford specification ESA-M1C198-A to the sealing faces of the main seal.

µ 13. Install a new bearing/knuckle O-ring and apply an even coat of Ford High Temperature Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A to the O-ring.

14. CAUTION:
Use extreme care when positioning the wheel hub and bearing assembly to the knuckle. Do not damage the bearing/knuckle O-ring. Any damage to the O-ring will cause a vacuum leak preventing the front hub lock from engaging resulting in a loss of four wheel drive operations.

CAUTION:
Carefully install the axle shaft into the knuckle avoiding contact with the main seal.

Position the axle shaft and the wheel hub in the wheel knuckle.

µ 15. Install the three wheel hub and bearing mounting bolts.

µ 16. Connect the tie-rod end.

1 Position the tie-rod end.

2 Install the nut.

3 Install a new cotter pin.

µ 17. CAUTION:
The retainer ring must be installed with the steel band facing outward. Failure to do so can cause failure of the retainer ring, resulting in the loss of four wheel drive operations/wheel end contamination.

Note:
The seal remover guide is used as a pressing handle when used in conjunction with the Pusher and the Snap Ring Sleeve in this operation.

Install the retainer ring installation tool.

1 Place a new retainer ring, with the steel band facing outward, onto the tool and place the tool onto the axle shaft.

2 Position the seal installer tool onto the Snap Ring Sleeve.

3 Position the Seal Remover Guide onto the Snap Ring Sleeve.

µ 18. CAUTION:
Be sure the retaining ring seats in the shaft groove by pulling and pushing firmly on the axle shaft and tool. Listen for an audible "CLICK" as the ring seats. Failure to seat the retaining ring will result in axle main seal leaks, loss of four wheel drive operations and wheel end contamination.

Install the retainer ring.

1 Pull and hold the axle shaft into the wheel knuckle.

2 Simultaneously press on the tool until the retainer ring seats.

µ 19. Install a new wheel hub O-ring and apply an even coat of Ford High Temperature Wheel Bearing Grease E8TZ-19590-A or equivalent meeting Ford specification ESA-M1C198-A to the O-ring.

µ 20. Install the four vacuum/ABS harness retainers into the frame.

µ 21. Connect the vacuum hose, and if equipped, the ABS harness electrical connector.

µ 22. Install the brake disc shield.

µ 23. Note:
Always reuse hub locks if not cracked or broken.

Note:
It may be necessary to bounce the axle shaft and turn the wheel hub to align the hub lock splines.

Note:
To aid in hub lock installation, the hub lock should be in the engaged position while aligning it to the axle shaft and the hub and bearing.

Install the hub lock.

1 Position the hub lock onto the wheel hub using hand pressure, then using a rubber mallet, install the hub lock.

2 Inspect all of the hub lock locking arms to ensure that they are fully seated in the hub groove.

24. Perform the wheel-end vacuum leak test. For additional information, refer to «Vacuum Leak Test—Wheel-End» in this section.

25. Install the front brake disc. For additional information, refer to «Section 206-03».

26. Install the wheel and tire assembly. For additional information, refer to «Section 204-04».
