>> A << Washer/REA Driveshaft Nut Installation

CAUTION:

The magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that the magnetic encoder should not collect metallic particles. Check that there is not any trouble prior to reassembling it.
When installing the drive shaft, make sure that it does not contact with the magnetic encoder (integrated with the inner oil seal) to avoid damage.
Do not apply the vehicle weight on the rear wheel hub assembly before fully tightening the driveshaft nuts. Otherwise, the wheel bearing will be broken.

Incorporate the driveshaft washer as shown in the figure.
Using special tool MB990767, tighten the driveshaft nut. At this time, tighten the nut to the specified lower limit torque so that the pin hole may align with cotter pin.
Tightening torque: 144 - 176 N.m (107 - 129 ft-lb)
If the pin holes do not align with the pins, tighten the driveshaft nut [less than 176 N.m (129 ft-lb)] and find the nearest hole, then bend the cotter pin to fit it.
