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.
  • The part indicated with * is the bolt with friction coefficient stabilizer. In removal, replace it with a new one.
Post-installation Operation

REMOVAL SERVICE POINTS
 
 
<<A>> PARKING BRAKE CABLE CONNECTION REMOVAL (REAR BRAKE CALIPER ASSEMBLY SIDE)
Compress the tabs on the cable retainer to pull out the parking rear cable through the parking lever hole of the rear brake caliper assembly.
note
  • When pulling out the parking rear cable, be careful not to damage the tab on the cable retainer.
  • Example: Insert the 12.8-mm (0.5 inch) hose clip (MB248923) into the parking rear cable. Then push the clip over the cable retainer to protect the tabs.
 

 
 
<<B>> REAR BRAKE 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 DRIVESHAFT NUT REMOVAL
1.
caution
  • Make sure that the lock nut chisel is set in the correct direction. Otherwise, the groove or thread in the driveshaft may be broken, or the tip of the chisel may be chipped.
  • Never use a chisel which tip is damaged.
  • For how to use the lock nut chisel, refer to the manufacturer's operating instructions.
Set the special tool lock nut chisel (MB992700) in the groove of the driveshaft with its "UPPER" mark facing upwards. Then strike the staked portion of the driveshaft nut with the chisel and a hammer to raise up.
2.
cautionBe careful not to damage the thread of the driveshaft.
Raise up the staked portion of the driveshaft nut until it does not interfere with the shaft thread.
3.
caution
  • Never use a impact wrench to loosen the driveshaft nut.
  • Do not apply the vehicle weight on the wheel bearing with the driveshaft nut loosened. Otherwise, the wheel bearing may be broken.
Use special tool front hub and flange yoke holder (MB990767) to counter the hub, and remove the driveshaft nut.
 

 
 
 

 
 
<<D>> REAR WHEEL HUB ASSEMBLY REMOVAL
1. If the rear wheel hub assembly is seized with the rear driveshaft, use the following special tools to push the driveshaft out from the hub and then remove the rear wheel hub assembly.
  • Puller shaft (MB990242)
  • Puller bar (MB990244)
  • Puller body (MB991354)
  • Front hub and flange yoke holder (MB990767)
2. If the rear wheel hub assembly is seized with the trailing arm, use the following special tools to remove the rear wheel hub assembly.
Combination (A)
  • Slide hammer (MB990211)
  • Rear axle shaft puller (MB990241)
Combination (B)
  • Slide hammer (MB990211)
  • Puller body (MB991354)

>>A<< REAR 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 driveshaft, 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 rear driveshaft nuts. Otherwise, the wheel bearing will be broken.
1. Check the hub seated surface for damage or corrosion. Whenever solvent is used for removing the corrosion, the surface should be degreased.
2. Check that the new rear driveshaft nut can be turned smoothly by hand. Then tighten it until it is seated.
3. Using special tool front hub and flange yoke holder (MB990767), tighten the rear driveshaft nut.
Tightening torque: 250 ± 25 N·m (184 ± 18 ft-lb)
4. After tightening to the specified torque, check that the nut is seated securely.
5. Use the chisel and a hammer to stake the nut until the center in the staked portion reaches the shown dimension.
6. Finally, check that the nut is not cracked at its staked portion.
 

 
 
>>B<< REAR WHEEL SPEED SENSOR INSTALLATION
Push the rear wheel speed sensor to the end and install it securely.
 

 
 
>>C<< PARKING BRAKE REAR CABLE CONNECTION (REAR BRAKE CALIPER ASSEMBLY SIDE) INSTALLATION
1. Guide the parking brake rear cable through the parking lever hole of the rear brake caliper assembly to the cable retainer.
2. Pull back the parking brake rear cable to assure it is tightly fastened to the cable retainer.
