Tools Required
• | J 33792 Side
Bearing Adjuster Wrench |
- Slowly turn the J 33792
clockwise until the right
differential adjuster nut sleeve contacts the differential case bearing.
- Install the J 42213
to the left differential adjuster nut sleeve.
- Slowly turn the J 42213
clockwise until the left differential adjuster nut sleeve contacts
the differential case bearing.
- Mark the location of the adjuster nut sleeves in relation to the
carrier halves.
Ensure that the notches in the adjusting sleeves
can be counted when turned.
- Using the J 33792
, turn the right differential adjuster nut sleeve out two notches.
- Using the J 42213
, turn the left differential adjuster nut sleeve in 1 notch.
- Rotate the pinion several times in order to seat the bearings.
Measuring Backlash
- Install the J 34047
, the J 25025-1
, and the J 8001
as shown.
- Place the indicator stem at the heel of a tooth.
- Move the case through the case's free play while holding the pinion
flange.
- Record the dial indicator reading.
Specification
The backlash between the ring gear and the drive pinion should be between
0.08-0.25 mm (0.003-0.010 in) with a preferred specification
of 0.13-0.18 mm (0.005-0.007 in).
Important: When adjusting the backlash, observe the following:
• | Always turn the left and the right differential adjuster nut sleeves
in equal amounts. |
• | Turning the differential adjuster nut sleeves one notch will change
the backlash about 0.08 mm (0.003 in). |
• | Once the proper backlash is obtained, turn the left differential adjuster
nut sleeve in one additional notch in order to preload the differential
case side bearings. |
- If the backlash is too small, use the following procedure to adjust:
5.1. | Increase the backlash by turning the left differential adjuster
nut sleeve in 1 notch and the right differential adjuster nut sleeve out
1 notch. |
5.2. | Recheck the backlash and adjust as necessary. |
- If the backlash is too large, use the following procedure to adjust:
6.1. | Decrease the backlash by turning the right differential adjuster
nut sleeve in 1 notch and the left differential adjuster nut sleeve out
1 notch. |
6.2. | Recheck the backlash and adjust as necessary. |
- Once the proper backlash is obtained, turn the left differential
adjuster nut sleeve in 1 additional notch using the J 42213
in order to preload the differential
case side bearings.
- Recheck the backlash and adjust as necessary.
- Perform a gear tooth contact pattern check. Refer to
Gear Tooth Contact Pattern Inspection
