9.52. Use blue plastigage having a range of .004”-
.009” (.102-.229 mm) to measure the clearance
between the ring gear and the pinion gear.
See Figure 9.52.
• Position the plastigage so that it compresses
only against one side of the teeth. If it wraps
around one of the teeth, it will give a false read-
ing.
• The measurement should be taken on the
unloaded side of the gear. If the plastigage is
put on the loaded side of the gear, it will give a
false reading.
9.53. Add or remove shims from beneath the differen-
tial as necessary to obtain backlash of .009”+
.004” (.229 mm + .102mm). Repeat the mea-
surement after each change to confirm the
results. See Figure 9.53.
9.54. After backlash is set, it is necessary to set the
remainder of the end play between the differen-
tial and the left side axle housing.
9.55. Remove the differential set-up plate tool.
9.56. Confirm the presence of the spacer washer
between the left differential bearing and the left
inner axle bearing.
9.57. Add a known quantity of additional shim washers
having an inside diameter of .780” (1.98 cm).
The differential will be intentionally over-
shimmed. See Figure 9.57.
9.58. Position the left inner axle bearing, and install
the left axle through the bearings and shims.
See Figure 9.58.
