REMOVAL AND INSTALLATION


caution
  • Do not disassemble the rear wheel hub assembly.
  • The wheel speed detection 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 the rear wheel hub assembly is removed/installed, make sure that the wheel speed detection magnetic encoder (integrated with inner oil seal) does not contact with surrounding parts to avoid damage.
  • When removing and installing the rear wheel speed sensor, make sure that its pole piece at the end does not contact with surrounding parts to avoid damage.
  • The part indicated with * is the bolt with friction coefficient stabilizer. In removal, replace it with a new one.

REMOVAL SERVICE POINTS

<<A>> DRIVESHAFT NUT REMOVAL
caution Do not apply the vehicle weight on the rear wheel hub assembly with the driveshaft nut loosened. Otherwise, the wheel bearing will be broken.

Use special tool front hub and flange yoke holder (MB990767) to counter the hub as shown in the figure to remove the driveshaft nut.

<<B>> CALIPER ASSEMBLY REMOVAL
1.Remove the caliper assembly with brake hose.
2.Retain the removed caliper assembly with a wire and the like to prevent from falling.

INSTALLATION SERVICE POINTS

>>A<< WASHER/DRIVESHAFT NUT INSTALLATION

caution
  • The wheel speed detection 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 wheel speed detection 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.

1.Incorporate the driveshaft washer as shown in the figure.
2.Using special tool front hub and flange yoke holder (MB990767), tighten the driveshaft nuts to the specified torque. At this time, tighten the nuts within the specified torque range considering the final tightening.
Tightening torque: 144 - 176 N·m
3.If the pin holes do not align with the pins, tighten the driveshaft nut (less than 200 N·m) and find the nearest hole then bend the split pin to fit it.
