Backlash Adjustment
•
Check and adjust the gear backlash when any of the
backlash-related parts are replaced with new ones.
•
Clean any dirt and oil off the bevel gear teeth.
•
Assemble the front final gear case (see Front Final Gear
Case Assembly).
○
It is not necessary to install the variable front differential
control unit.
○
Check the backlash during tightening of the front final gear
case center cover bolts and stop tightening them imme-
diately if the backlash disappears. Then, change the ring
gear shim to a thicker one.
•
Temporarily, install the right front axle in the gear case
and hold it in a vise so that the ring gear is lower t han the
pinion gear.
