12. Use an impact gun to securely fasten down the (4) carrier cap fasteners.
Note: Do not completely torque them down at this point.
13. Recheck the backlash.
a. New Gearing: The backlash should be between 0.008" and 0.018" (0.20 and 0.46 mm).
b. Used Gearing: The backlash should be reset to what it was at the time of disassembly.
Note: If you have too much backlash, move the ring gear closer to the pinion. Count the number of notches you
back off the plain half threaded cup. Each notch equals about 0.003" (0.08 mm) of backlash.
IMPORTANT: In order to maintain the differential bearing preload, you will need to turn the flange half threaded
cup the same amount in the same direction. If you need more backlash, reverse the procedure.
14. After the gear pattern is correctly set. Torque the carrier cap fasteners as specified below.
