REMOVAL AND INSTALLATION



caution
  • The wheel speed detection magnetic encoder collects metallic particles easily, because it is magnetised. Make sure that the magnetic encoder should not collect metallic particles. Check that there is not any trouble prior to reassembling it.
  • When removing and installing the driveshaft assembly, make sure that the wheel speed detection magnetic encoder (integrated with the inner oil seal) does not contact with surrounding parts to avoid damage.
  • When removing and installing the front wheel speed sensor, make sure that the pole piece at the end does not contact with surrounding parts to avoid damage.
  • The parts indicated by * are the nuts with friction coefficient stabilizer. In removal, ensure there is no damage, clean dust and soiling from the bearing and thread surfaces, and tighten them to the specified torque.
Pre-removal operation
  • Engine Room Under Cover Removal (Refer to GROUP 51, Under Cover <Except PHEV>, <PHEV> ).
  • Transmission fluid draining (Refer to GROUP 22A, On-vehicle Service, Transmission oil replacement ). <M/T>
  • CVT fluid draining (Refer to GROUP 23A, On-vehicle Service, CVT Fluid Change ). <CVT>
  • Automatic Transmission fluid draining (Refer to GROUP 23C, On-vehicle Service, Automatic Transmission Fluid Change ). <A/T>

Post-installation operation
  • Using your fingers, press the ball joint dust cover to check for a crack or damage.
  • Engine Room Under Cover Installation (Refer to GROUP 51, Under Cover <Except PHEV>, <PHEV>).
  • Transmission fluid refilling (Refer to GROUP 22A, On-vehicle Service, Transmission oil replacement ). <M/T>
  • CVT fluid refilling (Refer to GROUP 23A, On-vehicle Service, CVT Fluid Change ). <CVT>
  • Automatic Transmission fluid refilling (Refer to GROUP 23C, On-vehicle Service, Automatic Transmission Fluid Change ). <A/T>
  • Check the beam direction of the headlamp (Low beam) (Refer to GROUP 54A - Headlamp Aiming ).

REMOVAL SERVICE POINTS



<<A>> DRIVESHAFT NUT REMOVAL


1.The staked portion of the driveshaft nut must face upwards.

2.
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.

3.
caution Be 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.

4.
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 as shown in the figure to remove the driveshaft nut.

<<B>> STABILIZER LINK DISCONNECTION



Use a hexagon wrench to remove the stabilizer link and strut connection nut as shown in the figure.

<<C>> SELF-LOCKING NUT (TIE-ROD END CONNECTION) REMOVAL



1.
caution
  • Loosen the self-locking nut (tie-rod end connection) from the ball joint, but do not remove here. Use the special tool.
  • To prevent the special tool from dropping off, suspend it with a cord.
Install special tool ball joint remover (MB991897 or MB992011) as shown in the figure.

2.Turn the bolt and knob to make the special tool jaws parallel, then hand-tighten the bolt. After tightening, check that the jaws are still parallel.
note To adjust the special tool jaws to be parallel, set the orientation of the knob as shown in the figure.
3.Unscrew the bolt to disconnect the ball joint.

<<D>> DRIVESHAFT ASSEMBLY REMOVAL




1.
caution
  • The wheel speed detection magnetic encoder collects metallic particles easily, because it is magnetised. Make sure that the magnetic encoder does not collect metallic particles.
  • When removing 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.
If the driveshaft is seized with the hub, use the following special tools to push the driveshaft assembly out from the hub:

  • Puller shaft (MB990242)
  • Puller bar (MB990244)
  • Front hub and flange yoke holder (MB990767)
  • Puller body (MB991354)

2.While pulling the lower side of the brake disc toward you, remove the driveshaft assembly from the hub.
caution
  • Never pull out the driveshaft assembly from the EBJ assembly side. Otherwise, the PTJ assembly may be damaged. Always pull out from the PTJ side with a lever.
  • Care must be taken to ensure that the oil seal of the transmission is not damaged by the spline part of the driveshaft assembly.

3.For driveshafts other than 2WD-RH driveshaft, insert a lever between the transmission case or transfer and driveshaft assembly, and then pull the driveshaft assembly out from the transmission.

caution Do not apply the vehicle weight to the wheel bearing with the driveshaft assembly removed. If, however, the vehicle weight shall be applied to the bearing (in order to move the vehicle), tighten the following special tools to the specified torque (270 ± 27 N·m):

  • Spacer (MB991000)
  • Front hub remover and installer (MB991017)

>>C<< DRIVESHAFT NUT INSTALLATION


caution Do not apply the vehicle weight on the front wheel hub assembly before fully tightening the driveshaft nut. Otherwise, the wheel bearing may 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.Using special tool front hub and flange yoke holder (MB990767), tighten the driveshaft nut.
Tightening torque: 270 ± 27 N·m
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 centre in the staked portion reaches the shown dimension.
6.Finally, check that the nut is not cracked at its staked portion.
