3 Installing the Air Locker
Select shims from the shim kit supplied with your Air Locker to
make the thickness ‘B’ as determined above.
NOTE : If necessary, shim kit ‘B’ can be made from the
standard Dana shims (not supplied) and put between
the bearing cone and bearing seat.
Place this shim pack on the bearing cup.
Re-measure the new distance ‘C’ from the Air Locker (now
including the shim pack ‘B’) to make sure that it matches ‘A’ on the
original differential.
NOTE : NEVER machine the Air Locker.
