>>I<< SIDE BEARING INNER RACE INSTALLATION
Use special tool MB990802 to press-fit the side bearing inner
races into the differential case.
.
>>J<< DRIVE GEAR BACKLASH ADJUSTMENT
Adjust the drive gear backlash by the following procedures:
1. Install the side bearing spacers, which are thinner than
those removed, to the side bearing outer races, and then
mount the differential case assembly into the gear carrier.
NOTE: Select side bearing spacers with the same thickness
for both the drive pinion side and the drive gear side.
2. Push the differential case assembly to one side, and
measure the clearance between the gear carrier and the
side bearing adjusting spacer with a feeler gauge.
3. Measure the thickness of the side bearing adjusting spacers
on one side, select two pairs of spacers which correspond to
that thickness plus one half of the clearance plus 0.05 mm
(0.002 inch), and then install one pair each to the drive
pinion side and the drive gear side.
