bearing

Rear wheel

assembly

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 rear driveshaft, 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 bear-

ing before fully tightening the rear driveshaft nut. Oth-
erwise, the rear wheel bearing may be broken.

Washer

1. Be sure to install the rear driveshaft washer in the illustrated

direction.

2. Using special tool MB990767, tighten the rear 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)

3. If the pin hole does not align with the pin, tighten the

driveshaft nut [less than 176 N

⋅ m (129 ft-lb)] and find the

nearest hole, then fit the cotter pin.
