Left Side Gear Backlash Adjustment
- Install the cam unit and the side thrust washer to the flange end of the differential case.
- Install the pinion gears and the side gear thrust washer into the differential case.
Align the openings of the pinion gears and the side thrust washer to the pinion shaft opening in the differential case.
- Press down on the side gear and install the pinion shaft.
If the side gear cannot be pressed down far enough to install the pinion shaft, replace the side gear thrust washer with a thinner washer.
- Install the pinion shaft lock bolt.
Tighten the pinion shaft lock bolt finger tighten.
- Rotate the pinion gear closest to the lock bolt so that one of the teeth is pointing downward (perpendicular to the ring gear flange).
- Insert a large tapered tool, such as a screwdriver, firmly between the side gear and the pinion shaft.
- Measure the backlash of the pinion gear and the side gear by doing the following:
- Install the J 7872 to the ring gear flange.
- Loosely clamp the J 8001 onto the stem of the J 7872.
- Place the contact pad of the J 8001
on one of the teeth of the pinion gear closest to the pinion shaft lock bolt.
Turn the dial of the J 8001 until the needle and the dial face indicate zero.
- Tighten the lock nut of the J 8001 finger tight.
- Pull the pinion gear firmly into the differential case seat.
- Rotate the pinion gear back and forth.
Record the measurement.
- Measure the backlash for the opposite pinion gear.
- Add the measurements together.
Specifications
- The backlash for the pinion gears should be 0.051-0.243 mm (0.002-0.010 in).
- If the backlash is too large, install a thicker side gear thrust washer and measure the backlash again.
- If the backlash is too small, install a thinner side gear thrust washer and measure the backlash again.
