How to Remove the Wheel Bearings on a 1982 Mercedes Benz 240D

1. Park the car on a flat and level surface. Ensure the back wheels are chocked. Loosen the lug nuts on the two front wheels. Do not remove the lugs until the car is lifted.
2. Place a jack under the front cross member of the car and raise it high enough to place jack stands under the cross member. Lower the car onto the jack stands.
3. Unscrew the lug nuts on the driver side of the car. Pull the wheel off the axle. Place it to the side.
4. Unbolt the caliper by unscrewing the bolts in the back with a socket wrench. Pull the caliper off and place it in the shock tower. Do not let the caliper hang by the brake line as this will damage the brake line.
5. Pry the dust cover in the middle of the assembly with a flat-tip screwdriver. This will expose the spindle nut.
6. Pull the cotter pin out of the spindle nut with a pair of pliers. Unscrew the nut with the pliers. Place the nut and the cotter pin in the dust cover for safe keeping.
7. Pull the outer bearing out by hand. The race should come out with the bearing.
8. Pull the rotor off the spindle. The rotor may not come out smoothly. Tap the rotor with a hammer to free any rust or sediment holding the rotor in place.
9. Tap the inner bearing with a hammer to loosen the bearing. Slide the bearing off by hand.
10. Repeat steps to remove the bearings on the passenger side.
