Use the front hub & flange yoke holder (special tool: MB990767) to fix the hub
as shown in the figure, and remove the lock nut.
|
|
1.Using a jack or a similar tool, support the axle assembly, and keep the drive shaft
to be horizontal.
|
|
2.
caution |
- Because the vehicle
speed detection encoder is magnetised, deposition of metal objects are prone to occur.Make sure
that the magnetic encoder does not have any deposition of foreign object. In addition, always
keep magnetic substances away from the magnetic encoder.
- When the drive shaft is removed, make sure that it does not contact with the vehicle
speed detection magnetic encoder 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:
- Axle shaft puller (MB990241)
- Front hub & flange yoke holder (MB990767)
caution |
- Be sure to use a lever without
a fail because the ETJ assembly or EDJ assembly may be damaged when the drive shaft is removed
from the EUJ assembly side.
- Care must be taken to ensure that the oil seal of the transmission is not damaged
by the spline part of the driveshaft.
|
|
|
3.Using a lever, disengage the EDJ assembly of drive shaft (RH) as well as ETJ assembly
of drive shaft (LH) from the transmission.
|
|
4.Lower the axle assembly from the centre of shock absorber lower side mounting section
with an amount not more than the dimension (A) described below. A: Approx. 60 mm 5.Remove the drive shaft (RH).
note |
- Work becomes easier when the drive shaft is removed from the right side, and installed
from the left side. Also, the removal becomes easier if the axle is pulled laterally.
|
|
|
6.When both the output shaft and drive shaft (RH) are removed together, separate according
to the steps below. (1)
Push the drive shaft (RH) into the transmission. (2)
Use a lever to disengage the circlip of drive shaft (LH). (3)
Lower the axle assembly from the centre of shock absorber lower side mounting section
with an amount not more than the dimension (A) described below. Then, remove the drive shaft
(LH). A: Approx. 100 mm (4)
Using the same manner, remove the drive shaft (RH) together with the output shaft. (5)
Using the sliding hammer (special tool: MB991721), remove the output shaft.

|
caution |
Do not apply the vehicle weight to the wheel bearing with the driveshaft assembly removed.
If the vehicle weight must be applied (e.g. when the vehicle must be moved), tighten the front
hub remover & installer (special tool: MB991017) to the specified torque (144 to 176
N·m).
|
|
|
Install the drive shaft (LH) while guiding it along the concave section of the transmission
case groove from the above.
|
|
1.Incorporate the driveshaft washer as shown in the figure. 2.Using the front hub & flange yoke holder (special tool: MB990767), tighten
the lock nut. Tighten it to the lower limit of specified torque in order to align the pin holes. Tightening torque: 144 to 176 N·m 3.If the pin holes are not aligned, retighten up to 176 N·m. Set the split
pin into the first aligned hole, and bend the split pin.
