(axle) yoke n u t u n t i l i t requires 1 N«m (10 in-lbs)
torque t o rotate the drive p i n i o n gear shaft (Fig. 55).
Use a Newton-meter or an inch-pound torque wrench
to measure the torque.
(14) Measure t h e drive p i n i o n gear depth of mesh

( w i t h t h e r i n g gear). Place t h e p i n i o n h e i g h t block
tool o n t h e face o f the drive p i n i o n gear ( F i g . 49).
Place t h e arbor and disc tools i n t o t h e d i f f e r e n t i a l
b e a r i n g cradles i n the differential housing (Fig. 50).
Place t h e gauge block tool w i t h t h e d i a l i n d i c a t o r
tool on the lowest step of the p i n i o n h e i g h t block tool
(Fig. 51). Ensure t h a t the gauge block tool is r e s t i n g
f i r m l y o n the lowest step of the p i n i o n h e i g h t block
tool and "zero" the d i a l indicator pointer.
(15) W i t h the d i a l indicator pointer "zeroed", move
the gauge block tool toward the arbor tool u n t i l t h e
t i p o f t h e d i a l indicator plunger contacts t h e arbor
tool ( F i g . 51). Slide t h e gauge block tool ( w i t h t h e
d i a l indicator) across and back and f o r t h along t h e
arbor tool w h i l e observing the d i a l indicator pointer.
Record t h e longest plunger t r a v e l distance
(whether

depth variance is w i t h i n 0.002 i n c h (0.05 m m ) o f the
depth variance etched into the d r i v e p i n i o n gear face,
i t is acceptable.
(17) I f the drive p i n i o n gear actual depth variance
is w i t h i n t h e specified tolerance, continue w i t h t h e
differential assembly. I f the actual depth variance is
not w i t h i n t h e specified tolerance, correct t h e s h i m
thickness accordingly and then re-measure t h e depth
variance.
