REMOVAL & INSTALLATION
See Figure 1
This procedure is for 2 wheel drive vehicles. For removal and installation for 4 wheel drive vehicles, refer to Drive Train .
The wheel bearings are only removed if they are worn. They cannot be removed without destroying them (due to side thrust created by the bearing puller). They are not periodically disassembled, repacked and adjusted.
- Remove the front wheel and support the car. Remove the attaching bolts and remove and suspend the brake caliper, hanging it from the body so as to avoid putting stress on the brake line.
- Remove the setscrew with an Allen wrench. Pull off the brake disc and pry off the dust cover with a small prybar.
- Using a chisel, knock the tab on the collar nut away from the shaft. Unscrew and discard the nut.
- Pull off the bearing with a puller set such as 31 2 101/102/104 and discard it. On the M3, use a puller set such as 31 2 102/105/106. On the M3, install the main bracket of the puller with 3 wheel bolts.
- If the inside bearing inner race remains on the stub axle, unbolt and remove the dust guard. Bend back the inner dust guard and pull the inner race off with a special tool capable of getting under the race (BMW 00 7 500 and 33 1 309 or equivalent). Reinstall the dust guard.
- If the dust guard has been removed, install a new one. Install a special tool (BMW 31 2 120 or equivalent; on M3, use 31 2 110 or equivalent) over the stub axle and screw it in for the entire length of the guide sleeve's threads. Press the bearing on.
- Reverse the remaining removal procedures to install the disc and caliper. Torque the wheel hub collar nut to 210 ft. lbs. (290 Nm). Lock the collar nut by bending over the tab.
