Adjust the backlash using an adjuster nut wrench to tighten or
loosen the adjuster nuts as required. (Refer to your vehicle service
manual.)

Recheck backlash as before, repeating this procedure until
backlash is within the specified amount.
IMPORTANT:
It is critical to set up bearing pre-load when a differential is
installed. Improper pre-load will result in undue bearing wear,
increased stresses in the differential center, increased running
noise, and ultimately, ring and pinion gear damage.
!
Set pre-load by tightening the right-hand adjuster nut (furthest away
from the crown wheel) by an amount specified in your vehicle
service manual.
!
Tighten the bearing cap bolts with a torque wrench to the torque
specified in your vehicle manufacturer’s service manual.
!
Install locking tabs onto the bearing caps.
