To service or repair the wheel hub and bearing, begin by raising and supporting the vehicle, next take off the wheel and tire assembly and last remove the disc brake caliper. Following that, take the dust cover, cotter pin, nut lock, nut and washer off the spindle, while being cautious to avoid the inner wheel bearing or seal touching the spindle's threads as you remove the hub/rotor. Open the hub/rotor, take out the inner bearing and wheel bearing and extract the inner and outer bearing cups with a pin punch. Place the new bearings with a fitting size tool, grease the hub inside and apply grease to both inner and outer wheel bearings. Seal the inner wheel bearing and the new bearing seal and before assembly, make sure the bearings and seals are free from rough surfaces on the spindle, then eliminate them and provide lubricant. After that, place the hub/rotor on the spindle and fit the outer wheel bearing, washer and retaining nut into place. While turning the hub/rotor, tighten the nut to a force of 41 - 54 Nm (30 - 40 ft. lbs.); as soon as you stop, loosen the nut to allow all bearing preload tension to be released. Loosen the bolt a little, try out the installed nut lock and new cotter pin as you apply caliper to measure the end play (the distance between the nut and frame line). Clean your dust cap, smooth on some lubricant inside without using too much and then put it back on. Now, put the disc brake caliper in place, attach the wheel and tire assembly and bring the car back down so it's finished.
