Rear Axle

REMOVAL AND INSTALLATION

CAUTION:
When removing and installing the rear wheel speed sensor, make sure that its sensor head does not contact with surrounding parts to avoid damage.













Required Special Tools:

- MB990242: Puller Shaft
- MB990244: Puller Bar
- MB990767: Front Hub and Flange Yoke Holder
- MB990998: Front Hub Remover and Installer
- MB991000: Spacer
- MB991354: Puller Body

REMOVAL SERVICE POINTS

[[A]] DRIVESHAFT NUT REMOVAL





CAUTION:
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.

Use special tool MB990767 to fix the hub and remove the driveshaft nut.

[[B]] DRIVESHAFT ASSEMBLY REMOVAL





1. Use special tools MB990242, MB990244, MB991354 and MB990767 to push out the driveshaft from the hub.

CAUTION:

- Do not pull out the driveshaft from the EUJ assembly side. Otherwise, the ETJ assembly will be damaged. Be sure to remove the driveshaft from the ETJ assembly side, by using a lever.
- Care must be taken to ensure that the oil seal of the differential carrier is not damaged by the spline part of the driveshaft.





2. Use a lever to remove the driveshaft (ETJ assembly side) from the differential carrier.





CAUTION:
Do not apply the vehicle weight to the wheel bearing with the driveshaft removed. If, however, the vehicle weight shall be applied to the bearing (in order to move the vehicle), use special tools MB990998 and MB991000 for tightening to the specified torque [144 - 176 Nm (107 - 129 ft-lb)].

CAUTION:
Care must be taken to ensure that the oil seal of the differential carrier is not damaged by the spline part of the driveshaft.

]]B[[ WASHER/DRIVESHAFT NUT INSTALLATION





CAUTION:

- The magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that the magnetic encoder does 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.





1. Assemble the driveshaft washer in the illustrated direction.
2. Use special tool MB990767 to tighten the driveshaft nuts. At this time, tighten the nuts within the specified torque range considering the final tightening.
Tightening torque: 144 - 176Nm (107 - 129 ft-lb)
3. If the pin holes do not align with the pins, tighten the driveshaft nut [less than 176 Nm (129 ft-lb)] and find the nearest hole then bend the cotter pin to fit it.
