9. Remove the axle shafts and carrier assembly from the
axle housing using the procedures as shown on
Page 8.
10.When carrier has been removed from the axle
housing, remove auxiliary pressure from the shift
cylinder.
CARRIER REMOVAL
Before carrier assembly can be removed from the axle
housing, the main differential lock must be engaged (in
the locked position). This must be done before the right-
side axle shaft is removed. Engaging (locking) the main
differential allows enough clearance for the clutch collar
to clear the carrier-to-housing mounting flange so removal
can be achieved.

AIR PRESSURE METHOD
1. Drain lubricant from the axle assembly.
2. Raise the right-side rear drive wheel off the floor
using a hoist or jack.
3. Hold the right-side of the vehicle in the raised
position by using a jack stand under the right-
side housing spring seat.
4. Disconnect the drive shaft from the input yoke.
5. Disconnect air line from the differential lock
shift cylinder.
6. Connect an auxiliary air supply to the differen-
tial lock shift cylinder.

7. Apply and hold air pressure to the shift cylinder.
This will move the clutch collar inward and engage
splines with the differential case splines,
locking the assembly.
8. To ensure differential clutch collar and case half have
engaged completely, rotate the drive pinion or the
right-side wheel.
