How to Replace the Wheel Bearing on a BMW 528i


1. Loosen the five lug nuts on the wheel that has the faulty wheel bearings, using your lug nut driver. Attach a breaking bar to the driver if you need more leverage to loosen the lug nuts. Set the jack under the 528i near this wheel. Raise the car. Slide a jack stand under the 528i. Lower the BMW onto this jack stand. Finish removing the five lug nuts. Pull off the wheel.
2. Remove the two 14 mm bolts securing the caliper to the rotor. Cut a long strand of wire. Pull the caliper off the rotor. Hang the caliper from the strut or suspension coil with the wire so that it does not dangle and damage the hydraulic brake line.
3. Loosen and remove the central spindle nut with your 19 mm socket, ratchet and breaking bar.
4. Pull off the rotor with your hands. Tap the back of the rotor with a mallet if it is stuck.
5. Disconnect the ABS harness from the back of the wheel bearing hub.
6. Remove the three 14 mm bolts from the back of the steering knuckle to pull off the wheel bearing. If the wheel bearing is stuck, tap the back of it with your mallet. If it still doesn't move, pry it off with a chisel and mallet. Pull off the wheel bearing shield and the seal with your hands.
7. Clean the surface of the knuckle with medium-grit sandpaper. Lay grease over the mating surface of the knuckle. Set the new wheel bearing seal in the knuckle. Set the shield on the knuckle. Mount the new wheel bearing hub with the three 14 mm bolts you removed earlier. Connect the anti-lock brake connector to the new wheel bearing hub.
8. Replace the rotor, caliper and spindle nut. Replace the wheel. Lower the 528i.
