CAUTION: Do not damage the ring gear and pinion.
Using the special tools, spread the differential housing.
^
Use a soft face hammer to seat the differential into the differential housing.
-
Remove the special tools after seating the differential in the differential housing.
34. CAUTION: Match the positioning of the mating letters on the bearing caps and the differential housing.
Install the bearing caps.
35. Using the special tools, measure backlash at three equally spaced points.
^
The backlash must be within the specifications, and cannot vary more than 0.05 mm (0.002 inch) between points checked. A backlash
variation or more than 0.05 mm (0.002 inch) indicates gear/case runout.
-
Make the necessary corrections by moving shims from one side of the differential case to the other, until the correct backlash adjustment is
achieved.
-
Correct for high backlash by moving the ring gear toward the pinion.
-
Correct for low backlash by moving the ring gear away from the pinion.
36. Check the gear tooth contact pattern.
