Removal and Replacement
DRIVESHAFT ASSEMBLYREMOVAL 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. [Vehicles with ABS]
^ 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. [Vehicles with ABS]
^ 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. [Vehicles with ABS]
^ 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 Steps 1-11:
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]] SELF-LOCKING NUT (TIE-ROD END CONNECTION) REMOVAL
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 rope.
1. 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.
[[C]] DRIVESHAFT ASSEMBLY REMOVAL
CAUTION
^ The magnetic encoder collects metallic particles easily, because it is magnetized. Make sure that the magnetic encoder does not collect metallic particles. [Vehicles with ABS]
^ When removing the driveshaft, make sure that it does not contact with the magnetic encoder (integrated with the inner oil seal) to avoid damage. [Vehicles with ABS]
1. 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 transmission is not damaged by the spline part of the driveshaft assembly.
3. 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 MB991000 and MB991017 to the specified torque 144-176 Nm (107-129 ft-lb).

]]B[[ 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. Incorporate the driveshaft assembly washer as shown in the illustration.
2. Use special tool MB990767 to tighten the driveshaft nut. At this time, tighten the nuts within the specified torque range considering the final tightening.
Tightening torque: 144-176 Nm (107-129 ft-lb)
3. If the pin holes do not align with the pins, tighten the driveshaft nut [less than 200 Nm (147 ft-lb)] and find the nearest hole then bend the split pin to fit it.
