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, count the
number of notches you back it off, each notch equals about
.003" 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 re-
verse this procedure.
1.
Install carrier bearings caps and torque carrier cap
bolts to 370–430 lbs. ft. (501–583 N•m)
2.

in straight or fully seated the backlash will change.

Used Gearing: Reset to backlash recorded be-
fore disassembly.

New Gearing: Backlash should be between
0.006 and 0.018".
