NOTE : Be sure to measure using the bearing cup that

originally came off of the right-hand side.

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.

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 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.

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.
