F Using a caliper or similarly accurate measurement method
(i.e., able to take accurate measurements within 0.04mm [0.0015”]),
measure the distance from the shoulder of the outer face of the
bearing cup to the ring gear mounting face (shown as ‘A’ in Figure
5.) and record this measurement as ‘A’.
NOTE : Be sure to measure using the bearing cup that
originally came off of the right-hand side.
F Remove the bearings from the original carrier using an automotive
bearing puller (ARB #0770001). Inspect the bearings for wear or
damage and replace if necessary.
F Apply a thin film of high pressure grease to both bearing journals of
the Air Locker to prevent seizing.
F Using a bearing press or arbor press, press one of the bearing
cones onto one bearing journal of the Air Locker (refer to Figure 6.)
until the bearing seats firmly against the bearing journal shoulder.
NOTE : Do not add any shims between the bearings and the
bearing seat, even if they were present on the OE
carrier.
Figure 6.
F
Invert the Air Locker and press the other tapered roller bearing
cone onto the opposite bearing journal of the differential carrier until
the bearing seats firmly against the bearing journal shoulder.
