REMOVAL
(1) Remove pinion gear nut and washer. Use Puller
C-452 and Wrench C-3281 to remove the pinion yoke.
(2) Drive pinion gear out of housing with plastic or
rawhide hammer. This will damage the front
bearing rollers and bearing cup. The front
bearing and cup must be replaced.
(3) Remove the collapsible preload spacer
(4) Remove the pinion seal with Puller C-748.
(5) Remove the front and rear bearing cups with
Remover Set C-4306 and Handle C-4171.

RING
GEAR
Do not remove ring gear from case unless
runout must be measured.
(1) Clamp the case (with the ring gear bolts facing
upward). Use a vise equipped with soft jaws (brass).
(2) Remove and discard the ring gear bolts. The
bolts have left-hand threads. Use a hammer and a
brass drift to force the ring gear loose from the case
pilots. Remove the ring gear.
CASE FLANGE RUNOUT MEASUREMENT
(1) If the ring gear runout exceeded 0.005 inch
(0.13 mm), case flange runout should be measured.
Install the case with the bearing cups and the
threaded adjusters close to their original position.
(2) Install the bearing caps and bolts. Tighten the
bolts lightly. Use Wrench C-4164 to thread both ad­
justers inward. Remove all side play.
(3) Attach Dial Indicator to measure the flange
runout. The plunger should contact the ring squarely
between the outer edge and the gear attaching bolt
holes (Fig. 16).
Fig. 16 Case Flange Runout Measurement
(4) Rotate the differential case several times and
observe the dial indicator. Mark the area of maxi­
mum flange runout. The differential case flange
runout must not exceed 0.003 inch (0.08 mm). If the
runout exceeds this amount replace the differential
case.
To reduce ring gear runout positioning the
ring gear runout mark 180 degrees opposite the
flange runout mark.
(5) Remove the differential bearing cap bolts. Re­
move the differential case from the differential hous­
ing.
DIFFERENTIAL CASE DISASSEMBLY
(1) Rotate the side gears until the pinion gears are
located at differential case opening and remove them.
(2) Remove the side gears and the thrust washers.
(3) Remove the differential bearings from the case
hubs with Bearing Splitter Bridge 938 and Bearing
Splitter 1130 (Fig. 17).
