REMOVAL AND INSTALLATION


caution
  • The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure that the magnetic encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.
  • When the drive shaft assembly is removed and installed, make sure that the magnetic encoder does not contact with surrounding parts to avoid damage.
  • When the drive shaft assembly is removed and installed, front wheel speed sensor must be removed to avoid damage.
Pre-installation Operation
  • Transmission Fluid Draining (Refer to GROUP 22A and 23A, On-vehicle Service - Transmission Oil Replacement , ).

 Post-installation Operation
  • Check the Ball Joint Dust Cover for cracks or damage by pushing it with your finger.
  • Transmission Fluid Filling (Refer to GROUP 22A and 23A, On-vehicle Service - Transmission Oil Replacement , ).

REMOVAL SERVICE POINTS

<<A>> DRIVE SHAFT NUT REMOVAL
caution Do not apply pressure to the wheel bearing by the vehicle weight to avoid possible damage when the drive shaft nut is loosened.

Use special tool front hub and end yoke holder (MB990767) to fix the hub and remove the drive shaft nut.

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

1.
caution
  • Do not remove the nut from ball joint. Loosen it and use special tool to avoid possible damage to ball joint threads.
  • Hang special tool with cord to prevent it from falling.
Install special tool ball joint remover (MB991897) as shown in the figure.

2.Turn the bolt and knob as necessary to make the jaws of special tool parallel, tighten the bolt by hand and confirm that the jaws are still parallel.
note When adjusting the jaws in parallel, make sure the knob is in the position shown in the figure.
3.Tighten the bolt with a wrench to disconnect the tie rod end.

<<C>> DRIVE SHAFT/DRIVE SHAFT AND INNER SHAFT ASSEMBLY REMOVAL


1.
caution
  • The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure that the magnetic encoder does not collect any metallic particle.
  • When the drive shaft or the drive shaft and inner shaft assembly is removed, make sure that it does not contact with the magnetic encoder and front wheel speed sensor to avoid damage.
Use the following special tools to push out the drive shaft or the drive shaft and inner shaft assembly from the hub.

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

2.Remove the drive shaft from the hub by pulling the bottom of the brake disc towards you.

3.
caution
  • Do not pull on the drive shaft; doing so will damage the TJ; be sure to use the pry bar.
  • When pulling the drive shaft out from the transmission, be careful that the spline part of the drive shaft does not damage the oil seal.
Insert a pry bar between the transmission case and the drive shaft, and then pry and remove the drive shaft from the transmission.

4.If the inner shaft is hard to remove from the transmission, strike the bracket assembly lightly with a plastic hammer and remove the inner shaft.

5.Use special tool plug (MB991460) to prevent the entry of foreign material into the transmission case.

caution Do not apply pressure to the wheel bearing by the vehicle weight to avoid possible damage when the drive shaft is removed. If, however, vehicle weight must be applied to the bearing in moving the vehicle, temporarily secure the wheel bearing by using the following special tools.

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

caution
  • The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure that the magnetic encoder should not collect any metallic particle. Check that there is not any trouble prior to reassembling it.
  • When the drive shaft is installed, make sure that it does not contact with the magnetic encoder and front wheel speed sensor to avoid damage.
  • When installing the drive shaft or the drive shaft and inner shaft assembly, be careful that the drive shaft or the drive shaft and inner shaft assembly do not damage the oil seal.

>>B<< WASHER/DRIVE SHAFT NUT INSTALLATION

1.Be sure to install the drive shaft washer in the specified direction.
2.
caution Before securely tightening the drive shaft nuts, make sure there is no load on the wheel bearings. Otherwise the wheel bearing will be damaged.
Using special tool front hub and end yoke holder (MB990767), tighten the drive shaft nut to the specified torque.
Tightening torque: 245 ± 29 N·m
