- Tighten special tools MB990998 and MB991000 to the specified torque. Tightening torque: 144 - 176 N.m (107 - 129 ft-lb)
- Hold the front wheel hub assembly in a vice with a wooden block.
- Rotate the hub in order to seat the bearing.
- Measure the wheel bearing rotation starting torque by using special tools MB990326 and MB990685. Limit: 1.4 N.m (12.39 in-lb)
- If the rotation starting torque is not within the limit range, replace the front wheel hub assembly. If there is any signs of binding or tight spots when the wheel bearing turns, also replace it.
- Measure to determine whether the wheel bearing end play is within the specified limit or not. Limit: 0.05 mm (0.002 inch)
- If the play is not within the limit range while the nut is tightened to 144 - 176 N.m (107 - 129 ft-lb), replace the front wheel hub assembly.
