3.4 Final Air Locker Assembly
Clean all parts of the differential assembly, paying particular
attention to the seal housing journal.
Place the Air Locker into the differential housing and install the
bearing caps.
NOTE : Be sure to check that the bearing caps are on the
correct sides of the third member and are correctly
aligned.
Insert the bearing cap bolts and hand tighten.
NOTE : Before attempting to install the adjuster nuts, make
sure the threads on the inside of the bearing caps and
differential housing are perfectly aligned. If they are
not, the threads could be stripped.
Insert and lightly hand tighten the adjuster nut supplied with the Air
Locker kit into the ring gear side bearing cap.
NOTE : You should feel no backlash between the ring and
pinion gears once the adjuster nut tightens.
Reverse the adjuster nut (counterclockwise) ¼ turn.
Insert the original adjuster nut onto the opposite side of the
differential and tighten with the appropriate adjuster nut wrench.
NOTE : You should now feel some backlash between the ring
and pinion gears. If not, there might be a clearance
problem which is binding the carrier. Re-check the
clearance.
