Note where Old and New Pinion Marking columns
intersect. Intersecting figure represents plus or mi­
nus amount needed.
For example, if old pinion is plus (+) 1 and the new
pinion is minus (-) 3, intersecting figure is (+)0.004
inch (0.10mm). Add this amount to the original shim.
Or if the old pinion is (-) 3 and the new pinion is (-)
2, intersecting figure is (-)O.OOl inch (0.025mm). Sub­
tract this amount from original shim. Refer to the
Pinion Gear Depth Variance Chart.
DIFFERENTIAL AND PINION MEASUREMENT
DIFFERENTIAL ZERO END PLAY
MEASUREMENT
(1) Place Master Differential Bearing D-345 for 44
axle or D-343 for 60 axle on the case hubs (Fig. 42).
(2) Install a pilot stud at the right side of housing.
Attach Dial Indicator to the pilot stud. Load indica­
tor plunger against the back of trie ring gear (Fig.
43).
(3) Insert a small pry bar between the bearing cap
and left side of differential case. Pry the case as far
as possible to right side (Fig. 43). Zero the dial indi­
cator pointer.
(4) Pry the case to left side and record the travel
distance.
The measurement above is the shim thickness
necessary for case zero end-play. The total
thickness will be determined during the ring
gear backlash adjustment.
(5) Remove indicator and pilot stud.

PINION GEAR DEPTH MEASUREMENT
Pinion gear depth measurement is necessary
when;
• Axle housing or differential case is replaced
• Pinion select shim pack is unknown
• Ring and pinion gears are replaced
Measurements are done with pinion cups and pin­
ion bearings installed in housing. Take measure-
