fasten with nuts, capscrews and lock washers.
Tighten to proper torque specifications. See the
Torque Chart.
Note: Use Spicer approved RTV compound on axle housing
mating surface. Completely remove all old gasket material
prior to applying new material. Compound will set in
20 minutes. Install axle housing cover and output shaft
assembly before compound sets or reapply.
11. Install the output seal.
12. Install output yoke.
Note: Use of a torque multiplier is recommended.
TIP: If you can't get the correct torque on yoke nut,
try torquing the nut with the truck wheels on the
ground and with the axle shafts installed.
13. Install axle shafts and axle stud nuts (If used, also
install lock washers and taper dowels).
14. Connect inter-axle driveline. Make sure driveline is
properly phased. Lubricate u-joints.
15. Add axle lubricant. Fill to bottom of filler hole.
When axle has been disassembled or housing, axle shafts
or wheel equipment replaced, check axle assembly for
proper differential actions before operating vehicle. Wheels
must rotate freely and independently.
Road test vehicle to bring axle lubricant up to temperature.
Recheck joints, drain and fill plugs for leakage. Retighten as
necessary.
