Measure and Adjust Carrier Assembly
Adjust Backlash and Preload
1. Turn the flange half bearing adjuster in until the ring
gear contacts the pinion (zero backlash) then back
the adjuster out two notches of the adjuster lugs.
2. Tighten the plain half adjuster until the bearing cup
just starts to turn, this is a zero bearing preload.
3. Tighten the plain half adjuster two lug notches. Start
with the notch at the top, count two notches counter-
clockwise on the adjuster, turn the adjuster so that
the notch is facing straight up. You now have a two
notch preload.
4. Use a rubber mallet to make certain that both bearing
adjusters are fully seated.
5. Measure backlash. Make sure it is within specifica-
tion of .006"–.018".
TIP: To give yourself room to adjust contact pattern,
set it between .010"–.012".
