Change Backlash Setting

If you have too much backlash, the ring gear needs to move
closer to the pinion. Back off the plain half-adjuster, counting
the number of notches you back it off (each notch equals
about .003" [.08 mm] of backlash).

In order to maintain the differential bearing preload, you
will need to turn the flange half-bearing adjuster the same
amount in the same direction. If you need more backlash,
reverse this procedure.

1.

Install carrier bearing caps and torque carrier cap
bolts to 130–150 lbs. ft. (176-203 N•m).

2.

Recheck backlash: If the bearing adjusters were not
in straight or fully seated, the backlash will change.

a.

Used Gearing: Reset to backlash recorded
before disassembly.

b.

New Gearing: Backlash should be between
.006” and .018" (.15-.46 mm).

3.

Check ring gear tooth contact pattern. Paint ring gear
teeth and check tooth contact pattern. Correct tooth
patterns, see "Adjust Tooth Contact Pattern."

4.

Install bearing adjuster cotter pins.

Measure Ring Gear Runout

Measure Ring Gear Total

1.

Measure ring gear total radial runout. (Indicator
reading should not exceed .010" [.25 mm]).

2.

Measure ring gear total backface runout. (Indicator
reading should not exceed .010" [.25 mm]).
