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 at the end does not contact with surrounding parts to avoid damage.
  • During maintenance, take care not to contact the parts or tools to the caliper because the paint of caliper will be scratched. And if there is brake fluid on the caliper, wipe off quickly.
  • 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 fix the hub and remove the rear driveshaft nut.

<<B>> 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 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 bearing before fully tightening the rear driveshaft nut. Otherwise, the rear wheel bearing may be broken.

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.
