FRONT AXLE ± Differential Carrier
26-38
NOTE
The special tool cannot be turned a full revolution, so
turn it several times within the range of movement to
run in the bearing, and then measure the rotation torque.
4. Clean the side bearing hub.
5. Install the special tools to the side bearing hub of the
gear carrier, and then install the bearing cap.
NOTE
Always check that the notch is in the shown position
and that the special tools are touching firmly against the
side bearing hub.
6. Use a thickness gauge to measure the clearance (A)
between the special tools.
7. Remove the special tools.
8. Use a micrometer to measure the special tool in the places
(B, C) shown in the illustration.
9. Install the bearing cap, and then use a cylinder gauge
and micrometer to measure the inside diameter (D) of
the bearing cap as shown in the illustration.
10. Calculate the thickness (E) of the required drive pinion
front shim by the following formula, and then select a
shim which most closely matches this thickness.
E = A + B + C±1/2D±86.0
11. Fit the selected drive pinion front shim(s) to the drive
pinion, and press-fit the drive pinion front bearing inner
race by using the special tool.
