The Ford Expedition brake rotors will shake if there is warping. This may feel like the SUV is "wobbling" when you apply the brakes. Mechanics call it "run-out." Another way to damage the rotors is by allowing the brake to wear too far beyond the recommended thickness. When they get beyond that point, the rivets start to cut grooves into the rotors. You may be able to machine the surface smooth again, but if the grooves are too deep, the rotor will be too thin to be safe.
Instructions
- 1
Place the wheel chocks behind the rear tires of the Expedition.
2Jack the Expedition, using the automobile jack, and place a jack stand near the jacking point. Raise the jack stand to the frame.
3Remove the lug nuts, using the lug wrench, and remove the wheel from the Ford. Remove the brake caliper, using a ratchet and socket. Secure the caliper to the strut, using a wire tie. Do not allow it to hang loose, or you will damage the brake line.
4Remove the grease cap from the wheel, using the screwdriver as a pry tool. Remove the cotter pin, using the pliers to pull it out of the shaft.
5Remove the retaining nut, using the proper size wrench. Remove the spindle nut with the wrench. Remove the bearing retainer ring, using the screwdriver, and pull the wheel bearing off the shaft. Pull the wheel rotor off by hand.
6Put the new rotor on the wheel assembly. Install the wheel bearing on the shaft, followed by the bearing retainer. Replace the spindle nut, and tighten it with the wrench. Install the retaining nut, and tighten it with a wrench. Place a new cotter pin through the retaining hole, and spread it apart with the pliers. Tap the grease cap onto the wheel with the rubber mallet.
7Replace the wheel on the Expedition, and tighten the lug nuts with the lug wrench. Remove the jack stand from under the SUV, and lower the vehicle to the ground. Repeat the process on the next wheel.
