4.1 Installing the Carrier Bearings
 With the Air Locker well supported in an arbor press, apply a thin
film of high pressure grease to both bearing journals.
 Identify the bearings according to where each was removed from
the OE diff, and allocate them to the correct sides of the Air Locker
respectively.
 Press one of the tapered roller bearing cones onto one of the
bearing journals of the Air Locker until the bearing seats firmly
against the bearing journal shoulder (Fig. 7.).
NOTE : Never re-use any bearings which are damaged or
worn.
 Invert the Air Locker and press the second bearing cone onto the
opposite bearing journal until the bearing seats firmly against the
bearing journal shoulder.
Figure 7.
NOTE : Do not add any shims between the bearings and the
bearing seat. Shimming of the Air Locker will be
performed with the supplied shim kits and/or the OE
master shims (if any) on the outside of the carrier
bearings.
