11. Install yoke nut using one of the following options:

g. Install a new nut with the pre-applied thread

adhesive compound. Tighten the nut to the
specified torque 680–832 lbs. ft. (920–1,130
N•m).

h. If a new nut with pre-applied thread adhesive

compound is unavailable, apply “Loctite 277" or
“271” (available in 0.5 ml tube—Dana P/N
129293) to the nut along two threads, for at
least two flats (120°) of the nut midway through
the thickness. Tighten the nut to the specified
torque 680–832 lb-ft. (530–1,130 N•m).

Follow the instructions specified by the thread adhesive

manufacturer when applying thread adhesive compound.

Note: Use of a torque multiplier is recommended.

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.

12. Install axle shafts and axle stud nuts (If used, also

install lock washers and taper dowels).

13. Connect inter-axle driveline. Make sure driveline is

properly phased. Lubricate U-joints.

14. 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.

15. Road test vehicle to bring axle lubricant up to tem-

perature. Recheck joints, drain and fill plugs for leak-
age. Retighten as necessary.
