Illustration 29 g01463348
39. Install differential case (5) to housing (6).
40. Install bearing nuts (7). Make sure that the bearing nuts (7) can turn freely.
Illustration 30 g01453350
Note: Marks need to be oriented correctly for the installation.
41. Install bearing caps (1).
Illustration 31 g01648223
42. Oscillate the bevel gear and advance bearing nut (7). Continue to advance the adjustment nut until there isno backlash. Back off the adjustment nut by 1/2 turn.
Illustration 32
g01648436
43. Use a torque wrench and Tooling (C) in order to measure the overall rolling torque at the pinion shaft. Torque should be 1.6 N路m to 2.4 N路m (14 lb in to 21lb in) above measured rotating torque of pinion.
44. Mount Tooling (J) on the carrier, as shown. Measure the backlash at four places on the bevel gear at 90 degree intervals. Compare the lowest reading to the specifications. The proper backlash setting is 0.180 mm to 0.230 mm (0.0071 inch to 0.0091 inch).
45. If the backlash is not within the specification, retract one adjustment nut and advance the opposite adjustment nut equally. This will maintain the bearing preload.
46. When proper backlash isobtained, tighten bearing cap bolts (2) to a torque of 266 N路m (196 lb ft).
47. Install lock plates (3) and bolts (4).
