REMOVAL AND 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 removing and installing the front driveshaft assembly, make sure that the 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 part indicated by*is the nut 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
  • Transmission Oil Draining (Refer to GROUP 22A, On-vehicle Service, Transmission Oil Change .)
  • Engine Room Under Cover Front Removal (Refer to GROUP51, Under Cover .)

 Post-installation operation
  • Using your fingers, press the Ball Joint Dust Cover to check for a crack or damage.
  • Transmission Oil Filling (Refer to GROUP 22A, On-vehicle Service, Transmission Oil Change .)
  • Engine Room Under Cover Front Installation (Refer to GROUP51, Under Cover .)

REMOVAL SERVICE POINTS

<<A>> FRONT DRIVESHAFT NUT REMOVAL
caution Do not apply the vehicle weight on the front wheel hub assembly with the driveshaft nut loosened. Otherwise, the wheel bearing may be broken.

Use special tool MB990767 to counter the hub as shown in the figure to remove the front driveshaft nut.

<<B>> 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.
  • If the dust cover is damaged during operation, replace the tie-rod end. (Refer to GROUP 37 - Power Steering Gear and Linkage Disassembly and Reassembly .)
Install special tool 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.Tighten the bolt with a wrench to disconnect the tie rod end.

<<C>>FRONT DRIVESHAFT ASSEMBLY REMOVAL


1.
caution
  • The magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that the magnetic encoder does not collect metallic particles.
  • When removing the front driveshaft, make sure that it does not contact with the magnetic encoder (integrated with the inner oil seal) to avoid damage.
If the driveshaft is seized with the hub, use special tools MB990242 and MB990244, MB990767 and MB991354 to push the driveshaft assembly out from the hub.

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

3.Insert a lever between the transaxle case or transfer and front driveshaft assembly, and then pull the front driveshaft assembly out from the transaxle.

caution Do not apply the vehicle weight to the wheel bearing with the front 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 MB991000 and MB990998 to the specified torque 144 - 176 N·m (107 - 129 ft-lb).

<<D>>OUTPUT SHAFT ASSEMBLY REMOVAL
caution When pulling the output shaft out from the transaxle, be careful that the spline part of the output shaft does not damage the oil seal.

Use special tool MB991721 to remove the output shaft assembly.

INSTALLATION SERVICE POINTS

>>A<< OUTPUT SHAFT ASSEMBLY/FRONT DRIVESHAFT ASSEMBLY 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 front driveshaft, make sure that it does not contact with the magnetic encoder (integrated with the inner oil seal) to avoid damage.
  • Care must be taken to ensure that the oil seal of the transaxle is not damaged by the spline part of the output shaft assembly or front driveshaft assembly.

>>B<< WASHER/FRONT DRIVESHAFT NUT INSTALLATION
caution Do not apply the vehicle weight on the front wheel hub assembly before fully tightening the front driveshaft nut. Otherwise, the wheel bearing may be broken.

1.Be sure to install the front driveshaft washer in the illustrated direction.
2.Using special tool MB990767, tighten the 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.
