Driveshaft Assembly Removal and Installation
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 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.

REMOVAL SERVICE POINTS
[[A]] DRIVESHAFT NUT REMOVAL
CAUTION:
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 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 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 magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that the magnetic encoder does not collect metallic particles.
- When removing the 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 disc toward you, remove the driveshaft assembly from the hub.
CAUTION:
- Never pull out the 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 driveshaft assembly.
3. Insert a lever between the transaxle case or transfer and driveshaft assembly, and then pull the driveshaft assembly out from the transaxle.
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 special tools MB991000 and MB991017 to the specified torque 144 - 176 Nm
(107 - 129 ft-lb).
[[E]]OUTPUT SHAFT ASSEMBLY (RH) 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.

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 driveshaft, make sure that it does not contact with the magnetic encoder (integrated with the inner oil seal) to avoid damage.

]]B[[ STABILIZER LINK CONNECTION
Use a hexagon wrench to install the stabilizer link and strut connection nut as shown in the figure.
]]C[[ WASHER/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. Be sure to install the driveshaft washer in the illustrated direction.
2. Using special 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 - 176Nm (107 - 129 ft-lb)
3. If the pin hole does not align with the pin, tighten the driveshaft nut [less than 176 Nm (129 ft-lb)] and find the nearest hole, then fit the cotter pin.
