4. Clean the side bearing seat thoroughly.
5. Set the special tool on the side bearing seats, and position
the cutout section as shown in the illustration. Then confirm
that the special tool contacts with the side bearing seats
completely.
6. Use a thickness gauge to measure the clearance (A)
between the special tools.
7. Remove special tools MB990720, MB990858, MB991169
and MB991170.
8. Use a micrometer to measure dimensions (B) and (C)
of the special tools.
9. Install the bearing cap, and then use a cylinder gauge
and the micrometer to measure the inside diameter (D)
of the bearing cap as shown in the illustration.
10. Calculate the thickness (F) of the drive pinion rear shim
from the following equation, and select the shim that is
closest in thickness to this value.
F = A + B + C ± 1/2 D ± 100
11. Fit the selected drive pinion rear shim(s) to the drive pinion,
and press-fit the drive pinion rear bearing inner race by
using the special tool.
" DA DRIVE PINION TURNING TORQUE ADJUSTMENT
Adjust the drive pinion turning torque by using the following
procedure:
1. Insert the drive pinion into the differential carrier, and then
install the drive pinion spacer, the drive pinion front shim,
the drive pinion front bearing inner race, and the companion
flange in that order.
NOTE
Do not install the oil seal.
