- Install special tools MB991000, MB990998 and tighten them to the specified torque. Tightening torque: 226 +/- 29 N.m (167 +/- 21 ft-lb)
- Hold front wheel hub assembly in a vice, using wooden blocks.
- Rotate the hub in order to seat the bearing.
- Measure the wheel bearing rotation starting torque by using the special tools MB990326 and MB990685. Limit: 1.4 N.m (12 in-lb)
- If the rotation starting torque is not within the limit when the nut is tightened to 226 +/- 29 N.m (167 +/- 21 ft-lb), replace the front wheel bearing assembly. If there is any signs of binding or tight spots when the wheel bearing turns, replace it.
- Measure to determine whether the wheel bearing axial play is within the specified limit or not. Limit: 0.05 mm (0.002 inch)
- If the play exceeds the limit when the nut is tightened to 226 +/- 29 N.m (167 +/- 21 ft-lb), replace the front wheel hub assembly.
