Raise the vehicle off the ground using a car jack. Ensure you place the jack underneath the frame of the vehicle so it is secure. Support the car jack with jack stands for added support.
Use a socket wrench to remove the lug nuts from the rear wheel. Lift the wheel off the axle and place it in a secure place for reattachment later.
Remove the mounting bolts attached to the brake caliper. Lift the brake caliper from the vehicle, being careful to not damage the brake hose.
Take the bearing races off the hub. If they are on tight, use a hammer to gently knock them off. Remove the old bearings from the vehicle. If the bearings have any grooves or holes in them, they need to be thrown away. Insert the new bearings in the same positions from which you removed the old ones.
Reattach the brake assembly and the rear wheel, following the removal steps in reverse. Repeat the process on the other rear wheel. Once completed, test the vehicle in a secluded area to ensure the steering now works correctly.
Hub and Bearing
Removal & Installation
Ford Expedition
The hub is part of the disc brake rotor and cannot be service separately. The inner and outer wheel bearing and races are serviced individually. Make sure to have a new hub grease seal when servicing the wheel bearings.
1. Raise and safely support the vehicle.
2. Remove the wheel and tire assembly.
3. Remove the disc brake caliper.
4. Remove the disc brake pads and-rattle clips.
5. Remove 2 anchor plate retaining bolts and remove the anchor plate.
6. Remove the hub grease cap, cotter pin, retainer washer and the spindle nut.
7. Remove the wheel bearing retainer washer and the outer wheel bearing.
8. Remove the disc brake hub and rotor assembly.
9. Using a suitable seal remover, remove and discard the hub grease seal.
10. Remove the inner wheel bearing.
11. Clean and inspect the wheel bearings and races for unusual wear or damage. Replace parts as necessary.
12. Inspect the hub and break rotor assembly. If required, the hub and brake rotor assembly must be replaced as a unit.
To Install;
13. If needed, pack the wheel bearing with a suitable high temperature wheel bearing grease before assembly.
14. Install the inner wheel bearing in the hub and brake rotor assembly.
15. Install a new grease seal using a suitable installation tool.
16. Place the hub and rotor assembly on the wheel spindle and install the outer wheel bearing.
17. Install the retainer washer and spindle nut.
18. adjust the wheel bearing as follows;
a. Torque the spindle nut to 17-24 ft. lbs. (23-34 Nm) while rotating the wheel and tire assembly to seat the wheel bearings.
b. Back off the spindle nut no less than ½ turn.
c. Torque the spindle nut to 17 inch lbs. (2 Nm).
19. Install the retaining washer so the castellation are aligned with the cotter pin hole. Install a new cotter pin.
20. Place the anchor plate and install 2 retaining bolts. Tighten the bolts to 125-168 ft. lbs. (170-230 Nm).
21. Install the brake pad anti-rattle clip and install the disc brake pads.
22. Install the disc brake caliper.
23. Install the wheel and tire assembly. Torque the lug nuts to 83-112 ft. lbs. (113-153 Nm).
24. Check the wheel and tire assembly for proper rotation, then install the grease cap.
25. Lower the vehicle.
26. Road test the vehicle and check for proper operation.
---------------------Park the Expedition on a flat, paved surface, and do not set the parking brake. Place wheel chocks in front of the front wheels. Loosen the lug nuts on the rear wheels, then raise the rear of the Expedition with a jack, and support it with jack stands. Finish removing the lug nuts and rear wheels.Remove the rear brake drums. For disc brakes, use a ratchet and socket to remove the lower caliper mounting bolt and loosen the upper bolt. Pivot the caliper up and away from the rotor. Remove the rotor.Position a drain pan under the differential housing. Remove the bolts that hold on the carrier cover with a ratchet and socket. Catch the gear oil in the drain pan. Remove the old cover gasket, and use a gasket scraper to remove any material from the cover and the differential housing. Wipe both surfaces with a shop rag.Examine the carrier assembly inside the housing, and you'll see the large vertically mounted ring gear. Next to the ring gear, running through the carrier housing, you will see the pinion shaft. Rotate the carrier assembly until you're looking at the end of the shaft. It runs through holes in both sides of the carrier assembly. To the right of the shaft is a small bolt that screws into the carrier assembly and engages the end of the shaft. Place a large screwdriver between the differential housing and one of the bolts that holds the ring gear onto the carrier assembly. This is to prevent the carrier from turning when you remove the small bolt. Remove the bolt with a ratchet and socket.Rotate the carrier assembly 180 degrees until you're looking at the hole on the other side of the carrier assembly that holds the pinion shaft. Slide the shaft out of the carrier assembly in this direction. Pull the shaft out until the stepped part of the shaft contacts the ring gear.Push the outer end of the axle in toward the center of the differential housing. Move back under the Expedition; you will be able to see the end of the axle shaft. The axle shaft has a C-clip in a groove on the end of the axle. Use needle-nose pliers to carefully remove the clip. Remove the C-clip for the other axle in the same manner. Do not rotate the differential while the pinion shaft is pulled out. Slide the axles out of the end of the axle tubes.Attach an axle bearing puller to a slide hammer. Insert the bearing puller through the center of the bearing. Using the slide hammer, extract the bearing and oil seal. Repeat for the other bearing and oil seal. Clean the end of the axle tube with a shop rag. Note that there is a small step inside the axle tube that the axle bearing seats against.Tap the new bearing into the axle tube with a hammer and a socket the same size as the outside of the bearing. Seat the bearing against the step in the axle tube. Coat the rubber lip of the oil seal with gear oil. Use the same socket to tap the oil seal into the axle tube. Make sure the seal is flush with the end of the tube. Repeat for the other bearing and seal. Slide the axle into the axle tube far enough so you can reinstall the C-clip. After you install the clip, pull out on the axle to seat the clip in the recess in the small spider gear. Repeat for the other axle.Push the pinion shaft back through the carrier. Put a couple of drops of non-hardening thread sealer on the pinion shaft bolt, and reinstall the bolt. Torque the bolt to 20 foot-pounds with a torque wrench and socket.Coat the gasket mounting surface on the differential cover and the gasket mounting surface on the differential housing with gasket sealer. Coat one side of a new differential cover gasket with gasket sealer and press the gasket onto the differential cover. Coat the other side of the gasket with gasket sealer, and position the cover onto the housing. Install the bolts, and tighten them until the cover is just seated against the housing. Moving in a crisscross pattern, torque the bolts 30 foot-pounds.Remove the filler plug from the differential cover. Add 4 ounces of limited-slip friction modifier to the differential, then fill it with 75W-140 GL-5 synthetic gear oil. The differential is full when the gear oil reaches the bottom of the filler hole. Replace and tighten the filler plug.Install the brake drum, or install the rotor and rotate the caliper back onto the rotor. Torque the caliper mounting bolts to 30 foot-pounds. Mount the wheels, and install the lug nuts. Raise the Expedition and remove the jack stands. Lower the Expedition to the ground. Tighten the lug nuts. Test drive, and check for leaks.
