Grease Seal and Bearing

Removal

 CAUTION: Sodium-base grease is not compatible with lithium-base grease and should not be intermixed. Therefore, do not lubricate front or rear wheel bearings without first identifying the type of original wheel bearing lubricant. Use of incompatible bearing lubricants could result in premature lubricant breakdown.

Wheel bearing lubricant is a lithium-base grease such as Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B.

If bearing adjustment will not eliminate looseness or rough and noisy operation, the hub and bearings should be cleaned, inspected and repacked with specified wheel grease. If the bearing cups or the cone and roller assemblies are worn or damaged, they should be replaced.

1. Raise the vehicle until the tire clears the floor and remove the wheel and tire assembly from the hub and rotor. Refer to Section 04-04.

2.  CAUTION: Do not let the disc brake caliper (2B120) hang with its weight on the front brake hose (2078) or the front brake hose may become stretched, twisted or ruptured.

   Remove the disc brake caliper (refer to Section 06-03) and wire to the underbody to prevent damage. Do not disconnect the front brake hose from the caliper.

3. Remove the grease cap, cotter pin, retainer, adjusting nut and washer.

4. Remove the front wheel bearing (1216).

5. Pull the hub and rotor off the front wheel spindle (3105). Remove and discard the wheel hub grease seal (1190).

6. Remove the bearing cone and roller (1201) from the hub.

7. Remove all traces of old lubricant from bearings, hub and front wheel spindle.

8. Inspect the cups for scratches, pits or cracks. If the cups are worn or damaged, remove with a drift.

9. Clean the bearing cone and roller and front wheel bearing with solvent and dry thoroughly. Do not spin the bearings dry with compressed air.

10. Inspect the cones and rollers for cracks, nicks, brinelling or seized rollers. Inspect the grease retainer and replace if cracked, nicked, dented or worn.

11. Cover the front wheel spindle with a clean cloth and brush all loose dust and dirt from the brake assembly using Rotunda Brake and Clutch Service Vacuum 164-R3600 or equivalent.

12. Remove the cloth from the front wheel spindle carefully to prevent dirt from falling on the front wheel spindle.

Installation

1. If inner bearing cup (1202) or outer bearing cup was removed, install replacement inner and outer bearing cups in the hub with the appropriate bearing cup replacer tool (T73T-1202A, T73T-4222A or T73T-4222-B) and Driver Handle T80T-4000-W.

   
   
   
   
   

2. Properly seat cups in hub. The cups are properly seated when fully bottomed.

3. Replace grease retainers. Polish grease retainer journal on front wheel spindle with 400 grit sandpaper. Clean with clean cloth.

4.  CAUTION: Make sure front wheel spindle and hub are clean prior to application of lubricant.

   Pack the inside of the hub with lithium-base grease such as Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B. Fill the hub until the grease is flush with the inside diameters of both bearing cups.

5. Pack the bearing cones and rollers with wheel bearing grease. Use Rotunda Wheel Bearing Packer 160-00045 or equivalent.

   If a packer is not available, work as much lubricant as possible between the rollers and cages. Lubricate the cone surfaces with grease.

6. NOTE: Different vehicles having different size bearings and wheel hub grease seals will require a different seal replacer.

   Place the bearing cone and roller in the bearing cup and install the new wheel hub grease seal with an appropriate tool such as Seal Replacer T73T-1190-B. Make sure the wheel hub grease seal is fully bottomed.

   
   
   
   
   

7.  CAUTION: Keep the hub centered on the front wheel spindle to prevent damage to grease retainer or spindle threads.

   Install the hub and rotor on the front wheel spindle.

8. Install the outer bearing cone and roller and front wheel outer bearing retainer washer (1195) on the front wheel spindle.

9. Install the adjusting nut and adjust the wheel bearing as described under Adjustments in this section.

10. Install the retainer and new cotter pin, bending both ends of cotter pin in opposite directions around retainer. Install grease cap.

11. Install the disc brake caliper. Refer to Section 06-03.

12. Install the wheel and tire on the hub. Refer to Section 04-04.

13. Lower vehicle and tighten lug nuts (1012) to Specification listed at the end of this section. Install the wheel cover (1130).

14. Before driving the vehicle, pump the brake pedal (2455) several times to restore normal brake pedal travel.
