REMOVAL AND INSTALLATION
 
 
cautionThe vehicle speed detection encoder collects any metallic particle easily, because it is magnetized. Make sure that the encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.
Pre-removal operation
  • Parking brake rear cable connection (Rear brake caliper side) Removal and Installation (Refer to GROUP 36 - Parking Brakes ). <Except for electric parking brake>
  • Drain differential gear oil (Refer to ).
  • Rear height sensor and control link disconnection (Refer to GROUP 34 - Control Link, Upper Arm and Lower Arm ).
  • Disconnect joints between the lower arm, trailing arm, shock absorber, and stabilizer link. (Refer to GROUP 34 - Control Link, Upper Arm, Lower Arm Removal and Installation ).
  • Disconnect joint between the upper arm and the trailing arm. (Refer to GROUP 34 - Control Link, Upper Arm, Lower Arm Removal and Installation ).
Post-installation operation
  • Connect the upper arm and the trailing arm. (Refer to GROUP 34 - Control Link, Upper Arm, Lower Arm Removal and Installation ).
  • Connect the lower arm, trailing arm, shock absorber, and stabilizer link. (Refer to GROUP 34 - Control Link, Upper Arm, Lower Arm Removal and Installation ).
  • Fill the differential gear oil (Refer to ).
  • Rear height sensor and control link connection (Refer to GROUP 34 - Control Link, Upper Arm and Lower Arm ).
  • Wheel alignment check and adjustment (Refer to GROUP 34 - On-vehicle Service - Rear Wheel Alignment Check and Adjustment ).
  • Check the beam direction of the headlight (Low beam) (Refer to GROUP 54A - Headlight Aiming ).
  • Parking brake rear cable connection (Rear brake caliper side) Removal and Installation (Refer to GROUP 36 - Parking Brakes ). <Except for electric parking brake>

REMOVAL SERVICE POINTS
 
 
<<A>> 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.
 

 
 
<<B>> DRIVESHAFT ASSEMBLY REMOVAL
1. If the driveshaft is seized, use the following special tools to push the driveshaft out from the hub:
  • Puller shaft (MB990242)
  • Puller bar (MB990244)
  • Puller body (MB991354)
  • Front hub and flange yoke holder (MB990767)
caution
  • Do not pull out the driveshaft from the outboard joint assembly side. Otherwise, the inboard joint assembly will be damaged. Be sure to remove the driveshaft from the inboard joint 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 (Inboard joint assembly side) from the differential carrier.
cautionDo 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 the following special tools for tightening to the specified torque [250 ± 25 N·m (184 ± 18 ft-lb)]:
  • Front hub remover and installer (MB990998)
  • Spacer (MB991000)

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 drive shaft, 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 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 driveshaft nut can be turned smoothly by hand. Then tighten it until it is seated.
3.
4. Using special tool front hub and flange yoke holder (MB990767), tighten the driveshaft nut.
Tightening torque: 250 ± 25 N·m (184 ± 18 ft-lb)
5. After tightening to the specified torque, check that the nut is seated securely.
6. Use the chisel and a hammer to stake the nut until the center in the staked portion reaches the shown dimension.
7. Finally, check that the nut is not cracked at its staked portion.
 

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