Rear Axle
REMOVAL AND INSTALLATION
CAUTION:
- Do not disassemble the rear wheel hub 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 the rear wheel hub assembly is removed/installed, make sure that the 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 sensor head 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.

- MB991354: Puller Body
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 MB990767 to fix the hub and remove the driveshaft nut.
[[B]] CALIPER ASSEMBLY REMOVAL
1. Remove the caliper assembly with brake hose.
2. Secure the removed caliper assembly with a wire or other similar material at a position where it will not interfere with the removal and installation of the rear wheel hub assembly.
[[C]] REAR WHEEL HUB ASSEMBLY REMOVAL
1. If the rear wheel hub assembly is seized with the rear driveshaft assembly, use special tools MB990242 and MB990244, MB991354 and MB990767 to push the rear driveshaft assembly out from the hub and then remove the rear wheel hub assembly.
2. If the rear wheel hub assembly is seized with the knuckle, use special tools MB990211 and MB990241 {combination (A)}, or MB990211 and MB991354 {combination (B)} to remove the rear wheel hub assembly.
INSTALLATION SERVICE POINTS
]]A[[ 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. Incorporate the driveshaft washer as shown in the figure.
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 - 176 Nm (107 - 129 ft-lb)
3. If the pin holes do not align with the pins, tighten the driveshaft nut [less than 200 Nm (147 ft-lb)] and find the nearest hole then bend the split ping to fit it.
