3.7.2 B Pre-Loading a Live Axle Housing
c Insert and hold the Air Locker into the differential housing.
c Insert the remaining master shim from the Air Locker shim kit
between the right-hand bearing cup and the bearing seat of the
axle housing with the rounded edge of the master shim facing away
from the center.
c Insert the shim pack determined earlier as ‘B’ between the bearing
cup (right-hand side) and the master shim.
c Push (or lightly pry) the Air Locker hard across to the right-hand
side, and measure the maximum gap (also called the ‘end float’)
between the outside of the seal housing and the inside face of the
axle housing with an automotive feeler gauge. (Fig.18.)
Figure 18.
c Consult your vehicle manufacturer’s service manual to determine
the carrier bearing pre-load amount specified for your vehicle.
c Add the specified pre-load amount to the measurement taken with
the feeler gauge to determine a shim amount for ‘D’ in Figure 13.
PRE-LOAD + END FLOAT = SHIM PACK
c Create a shim pack ‘D’ from the shims supplied with your Air
Locker.
NOTE : Do not add shims between the bearing cone and the
bearing seat and NEVER machine the Air Locker.
c Remove the Air Locker from the axle housing.
