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.

REMOVAL SERVICE POINTS

<<A>> REAR 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 counter the hub as shown in the figure to remove the driveshaft nut.

<<B>> REAR BRAKE CALIPER ASSEMBLY REMOVAL
1.Remove the brake caliper assembly with brake hose.
2.Secure the removed brake 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 POINT

>>A<< WASHER/REAR 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.

1.Incorporate the driveshaft washer as shown in the figure.
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.
