|
1.Remove one bolt from the
backing plate.
|
|
2.Apply gummed cloth tape
around the edge of the bearing case for
protection.
| caution |
Be careful not to damage the
bearing case and the axle shaft.
|
3.As shown in the figure, hold the axle
shaft. Using a grinder, shave off a point of
its circumference locally until the wall thickness become as
follows:
- 1.0 - 1.5 mm for axle shaft side
- 2.0 mm for bearing side
| caution |
Be careful not to damage the
bearing case and the axle shaft.
|
|
|
4.Fix the axle shaft and
shave off the remaining 2.0 mm on the side of the retainer
<Vehicles
without ABS> or Retainer assembly <Vehicles with
ABS>.
| caution |
Be careful not to damage the
axle shaft.
|
|
|
5.Cut in with a chisel the
place where the retainer <Vehicles without ABS> or
Retainer
assembly <Vehicles with ABS> has been shaven and
remove the retainer <Vehicles without ABS>
or Retainer assembly <Vehicles with ABS>.
|
|
1.Secure special tool axle
shaft bearing and case remover (MB991552) and extension bar
(MB991601)
to the bearing case bolts with the nuts and adjust the
height of the hanger. Then install the
washers, plate and nuts in that order.
| note |
The washers are used to
eliminate the difference in height of the
bearing case so that
the plate and the bearing case are
parallel.
|
| caution |
The hanger and plate should be
placed so that they are parallel.
|
2.Place the end of the bolt against the
centre of the axle shaft, and then tighten the
bolt to remove the axle shaft from the bearing case
assembly.
|
|
Install special tool rear axle
shaft bearing remover (MB990560) as shown in the
illustration,
and then use a press to remove the outer bearing inner race
from the axle shaft.
|
|
Reinstall the outer bearing inner
race that was removed previously. Use special tool ball
joint remover and installer A (MB990799) and a press to
remove the bearing outer race.
|
|
Use special tool rear suspension
bushing base (MB990890 or MB990891) to press-fit the
bearing outer race to the bearing case.
|
|
|
1.Set the outer bearing
inner race.
|
|
2.Apply multipurpose grease
to the outside of the oil seal.
3.Use the
following special tools, press-fit the oil seal into the
bearing case until
it is flush with the face of the bearing
case.
- Installer adapter (MB990936)
- Installer bar (MB990938)
4.Apply multipurpose grease to the lips of the
oil seal.
|
|
1.Apply multipurpose grease
to the roller surface and ends of the
bearing.
2.Pass the axle shaft through the bearing
case and the inner bearing inner race and
outer bearing inner race.
| caution |
Both the inner bearing inner
race and outer bearing inner race should be
press-fitted
together.
|
3.Use special tool ball joint remover and
installer A (MB990799) to press-fit the inner
bearing inner race and outer bearing inner race to the axle
shaft.
|
|
1.Use special tool ball
joint remover and installer A (MB990799) to press-fit the
retainer <Vehicles
without ABS> or Retainer assembly <Vehicles with
ABS> to the axle shaft. Check that the
press-fitting force is at the standard value.
2.If
the initial press-fitting force is less that the standard
value, replace the axle
shaft.
Standard value:
|
|
Initial
press-fitting force N
|
29,400 or
more
|
Final
press-fitting force N
|
98,000 -
107,800
|
|
|
|
1.After installing the snap
ring, measure clearance (A) between the snap ring and the
retainer <Vehicles
without ABS> or Retainer assembly <Vehicles with
ABS> with a feeler gauge. Check that it
is within the standard value.
Standard value
(A): 0 - 0.166 mm
2.If the clearance
exceeds the standard value, change the snap ring so that the
clearance
is at the standard value.
