3 Installing the Air Locker

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.

 Adjust the backlash and pre-load 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.

 Tighten all bearing cap bolts with a torque wrench to the torque

specified in your vehicle manufacturer’s service manual.
