3 Installing the Air Locker

Again check that no part of the seal housing tube comes in contact
with the moving differential components. Less than 8mm [5/16”]
should be considered too little clearance. Gently bend the tube
away from moving parts if necessary.
3.12 Reinstalling the Axles
Rotate the differential center until the circular access window in the
differential is in view and accessible.
Insert both axles fully into the housing and gently tap them inward.
NOTE : Be careful not to damage oil seals with the axle.
Install the ‘C’ clips on to the ends of the axles.
Gently tap the axles outward until both ‘C’ clips are fully seated.
Insert the cross shaft maintaining alignment between the cross
shaft retaining pin hole in the differential and its corresponding hole
in the cross shaft.
Ensure that some degree of axle end float exists (i.e., some
clearance exists between the end of the axle and the cross shaft or
thrust block). ‘C’ clips may need to be substituted with others of a
different thickness to achieve correct end float if too tight or too
loose.
Insert the cross shaft retaining pin (threaded end out) to its
maximum depth.
Apply thread locking compound to the threads of the button head
screw (supplied).
Assemble the locking washer onto the screw, and insert and tighten
the screw into the retaining pin hole.
Torque the button head screw to 24Nm [17.7 ft.lbs].
Reassemble brakes and wheels according to your vehicle’s service
manual.
