2-Wheel Drive Models

|WARNING |

|Before proceeding with any work on the front wheel bearings, read the precautions listed at the beginning of this section. |

1. Raise and support the front end on jackstands.

2. Remove the wheel cover. Remove the wheel.

3. Remove the caliper from the disc and wire it to the underbody to prevent damage to the brake hose. See Section 9.

4. Remove the grease cap from the hub. Then, remove the cotter pin, nut lock, adjusting nut and flat washer from the spindle. Remove the outer bearing assembly from the hub.

5. Pull the hub and disc assembly off the wheel spindle.

6. Remove and discard the old grease retainer. Remove the inner bearing cone and roller assembly from the hub.

7. Clean all grease from the inner and outer bearing cups with solvent. Inspect the cups for pits, scratches, or excessive wear. If the cups are damaged, remove them with a drift.

8. Clean the inner and outer cone and roller assemblies with solvent and shake them dry. If the cone and roller assemblies show excessive wear or damage, replace them with the bearing cups as a unit.

9. Clean the spindle and the inside of the hub with solvent to thoroughly remove all old grease.

10. Covering the spindle with a clean cloth, brush all loose dirt and dust from the brake assembly. Remove the cloth carefully so as to not get dirt on the spindle.

11. If the inner and/or outer bearing cups were removed, install the replacement cups on the hub. Be sure that the cups seat properly in the hub.

12. It is imperative that all old grease be removed from the bearings and surrounding surfaces before repacking. The new lithium-based grease is not compatible with the sodium base grease used in the past.

13. Install the hub and disc on the wheel spindle. To prevent damage to the grease retainer and spindle threads, keep the hub centered on the spindle.

14. Install the outer bearing cone and roller assembly and the flat washer on the spindle. Install the adjusting nut.

15. Adjust the wheel bearings by tightening the adjusting nut to 17-25 ft. lbs. (23-38 Nm) with the wheel rotating to seat the bearing. Then back off the adjusting nut 1/2 turn. Retighten the adjusting nut to 10-15 inch lbs. (1.1-1.7 Nm). Install the locknut so that the castellations are aligned with the cotter pin hole. Install the cotter pin. Bend the ends of the cotter pin around the castellations of the locknut to prevent interference with the radio static collector in the grease cap. Install the grease cap.

New bolts MUST be used when servicing floating caliper units. The upper bolt must be tightened first. For caliper service see Section 9.

16. Install the wheels.

17. Install the wheel cover.

1. Raise the vehicle and install jackstands.

2. Refer to Automatic Locking Hub Removal and Installation and remove the hub assemblies.

3. Using a socket made for that purpose, available at most auto parts stores, use the hub nut tool to unscrew the outer locking nut.

4. Remove the lock ring from the bearing adjusting nut. This can be done with your finger tips or a screwdriver.

5. Use the locknut socket to remove the bearing adjusting nut.

6. Remove the caliper and suspend it out of the way. See Section 9.

7. Slide the hub and disc assembly off of the spindle. The outer wheel bearing will slide out as the hub is removed, so be prepared to catch it.

8. Lay the hub on a clean work surface. Carefully drive the inner bearing cone and grease seal out of the hub using Tool T69L-1102-A, or equivalent.

9. Inspect the bearing cups for pits or cracks. If necessary, remove them with a drift. If new cups are installed, install new bearings.

10. Lubricate the bearings with Multi-Purpose Lubricant Ford Specification, ESA-MIC7-B or equivalent. Clean all old grease from the hub. Pack the cones and rollers. If a bearing packer is not available, work as much lubricant as possible between the rollers and the cages.

11. Drive new cups into place with a driver, making sure that they are fully seated.

12. Position the inner bearing cone and roller in the inner cup and install the grease retainer.

13. Carefully position the hub and disc assembly on the spindle.

14. Install the outer bearing cone and roller, and the adjusting nut.

The adjusting nut has a small dowel on one side. This dowel faces outward to engage the locking ring.

15. Using the hub nut socket and a torque wrench, tighten the bearing adjusting nut to 50 ft. lbs. (68 Nm), while rotating the wheel back and forth to seat the bearings.

16. Back off the adjusting nut approximately 90°.

17. Install the lock ring by turning the nut to the nearest hole and inserting the dowel pin.

The dowel pin must seat in a lock ring hole for proper bearing adjustment and wheel retention.

18. Install the outer lock nut and tighten to 160-205 ft. lbs. (217-278 Nm). Final end-play of the wheel on the spindle should be 0-0.004 in. (0-0.15mm).

19. Assemble the hub parts.

20. Install the caliper.

21. Remove the jackstands and lower the vehicle.

1. Raise the vehicle and install jackstands.

2. Refer to Manual Locking Hub Removal and Installation and remove the hub assemblies.

3. On Bronco, F-150 and F-250 LD with the Dana 44 axle: apply inward pressure on the bearing adjusting nut, using a socket made for that purpose, available at most auto parts stores, to disengage the adjusting nut locking splines, while turning it counterclockwise to remove it.On F-250 HD (Dana 50 axle) and F-350, use the hub nut tool to unscrew the outer locking nut. Then, remove the lock ring from the bearing adjusting nut. This can be done with your finger tips or an O-ring pick. Use the locknut socket to remove the bearing adjusting nut.
