Operation
Applicable RR DIFF or FR DIFF ENGAGE indicator must
be illuminated in instrument panel gauge cluster to validate
DIFF LOCK is FULLY engaged and axle shaft can be
removed.
Failure to fully engage axle DIFF LOCK will
allow DIFF LOCK shift collar to fall slightly and block, or
temporarily resist, axle shaft reinsertion.
2.
Remove cap screws and washers or stud nuts and
washers from flanges of both axle shafts.
3.
Loosen tapered dowels in flanges of both axle shafts
by holding a 1-1/2 inch diameter brass drift or hammer
against axle shaft center and hitting it with a 5- to
6-pound hammer.
4.
Remove tapered dowels and both axle shafts from axle
assembly.
5.
Assemble a cover over openings of both wheel ends to
prevent loss of lubricant and keep dirt from the wheel
bearing cavities.
Installing Axle Shafts
1.
Remove covers from wheel ends.
2.
Shift differential lock to the locked (engaged) position.
Applicable RR DIFF or FR DIFF ENGAGE indicator must
be illuminated in the instrument panel gauge cluster to
validate DIFF LOCK is FULLY engaged and axle shaft can
be removed. Failure to fully engage axle DIFF LOCK will
allow DIFF LOCK shift collar to fall slightly and block, or
temporarily resist, axle shaft reinsertion.
3.
Install right-side and left-side axle shafts as follows:
a.
Place gaskets on wheel hub studs.
b.
Push right-side axle shaft into wheel end and
housing until shaft stops against differential shift
collar.
c.
Push axle shaft further into housing until shaft stops
against differential side gear.
d.
Push down on axle shaft flange and rotate shaft until
splines of shaft and side gear are engaged.
e.
Push axle shaft completely into housing until axle
shaft flange and gasket are flush against wheel hub.
f.
Install left-side axle shaft and gasket into wheel end.
4.
If tapered dowels are required, install them at each stud
and into flange of axle shaft. Use a punch or drift and
hammer if needed.
5.
Install fasteners and tighten to correct torque value.
Refer to the appropriate Service Manual section.
Towing Vehicle With Rear Wheels Suspended
CAUTION
To prevent damage to cab roof or air deflector
when towing the vehicle backwards (rear wheels
suspended), the air deflector must be removed.
Whenever possible, it is preferable to tow a disabled vehicle from
the rear by raising the rear of the chassis by the rear axles.
When towing a vehicle with rear of the chassis suspended, the
front wheels must be locked in the straight ahead position.
