Caution
• If adjusting shims are to be reused, do not mix up the left and right shims.
• Do not mix up the left and right side bearing outer races and spacers.
8. Assemble the selected adjusting shims to the differential carrier ring gear side, and the spacer to the opposite
side.
9. Assemble the differential and bearing outer race to the differential carrier.
10. Tap the selected adjusting shim between the
spacer and the bearing race with a plastic
hammer as shown in the figure.
11. Align the bearing cap alignment marks to
assemble the bearing cap, and temporarily
tighten the bolts.
12. Place the dial indicator so that the measuring
probe contacts the top surface of one of the ring
gear teeth perpendicularly.
13. Secure the drive pinion and measure the
backlash from when the ring gear moved.
Specification
Backlash:
0.09—0.11 mm {0.003—0.004}
Minimum value:
0.05 mm {0.002 in}
Note
• Measure the backlash at 4 locations around the ring gear. Make sure one of the 4 locations is within
specification, and the minimum value for the 4 locations is 0.5 mm {0.002 in}or less.
14. If the backlash is not within the specification, adjust the gear case component by moving it in the axial direction.
Note
• When moving the gear case component in the axial direction, replace the adjusting shims. If the adjusting
shim on the right side is replaced with one that is 0.05 mm {0.002 in} thicker, replace the one on the left
with one that is 0.05 mm {0.002 in} thinner.
