3.1 Installing the Carrier Bearings
If the tapered roller bearings from the original differential carrier are
to be reused, then remove them with an automotive bearing puller
and inspect them for damage and/or wear and replace them if
necessary.
Apply a thin film of high pressure grease to both bearing journals of
the Air Locker to prevent seizing.
Using a bearing press or arbor press, press one of the bearing
cones (supplied with the Air Locker kit) onto one bearing journal of
the Air Locker until the bearing seats firmly against the bearing
journal shoulder.
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.
