Make certain that bearing bores are clean and free
of nicks and burrs. Adjust micrometer so it is directly
over end at a 90 deg. angle to step plate.
Run micrometer thimble down to measure distance
between center of ring gear and step plate. Make a note
of this reading along with the nominal dimension given in
"Specifications". Locate on pinion the etched marking
which indicates variation from zero cone setting. If it is a
minus figure, subtract it from specified dimension, and if
a plus figure, add it to specified dimension. Results of
calculation will provide the corrected pinion nominal
dimension to which pinion must be set. Comparison of
necessary for correct pinion position. It may be
necessary to add or remove shims between pinion cage
and diff carrier to provide correct pinion nominal
Remove gauge and prepare to install ring gear and
differential to diff carrier.
If ring gear was removed from diff case, rivet gear to
diff case flange. Use riveting fixture SE-2222 with
hydraulic press (Fig. 32). Rivet pressures (tons)
should be within the range given in "Specifications".

Apply rear axle lubricant to the inner walls of the diff
case halves and to all differential component parts.
Place side gear thrust washer and side gear in
flanged half of diff case and assemble spider, spider
gears and spider gear thrust washers to side gear.
Place opposite side gear and thrust washer in other
half of diff case.
Align the match marks and assemble the diff case.
Draw assembly together with four equally spaced
bolts and nuts. Make sure side gears and spider
gears mesh correctly.
Check for free rotation of side gears and spider
gears. If satisfactory, install remaining diff case bolts
Tighten diff case bolt nuts to specified torque (see
Install diff bearings by pressing them squarely onto
Install Differential On Diff Carrier
Pre-lubricate diff bearings with rear axle lubricant
and place bearing cups over bearings.
Lift differential assembly and place into position in
diff carrier. Tilt differential assembly to allow ring
gear to pass pinion pilot bearing.
Place bearing adjusters in carrier and turn hand tight
against bearing cups.
Assemble bearing caps to carrier. Align identifying
marks on bearing cap and carrier leg.
Install bearing cap bolts and washers. Tighten to
specified torque (see "Torque Chart").
Tighten bearing adjusters alternately until all end
play is eliminated. Revolve differential while
Set Gear Lash
A special effort should be made to set the backlash
between pinion and ring gear to the same amount as
was originally built into them (.15-.3 mm or .006-.012").
Generally the amount of backlash is stamped or etched
on the ring gear. When installing new gears, backlash is
measured with a dial indicator mounted
