(6) Note the etched number on the face of the
drive pinion gear ( - 1 , -2, 0, +1, +2, etc.). The num­
bers represent thousands of an inch deviation from
the standard. I f the number is negative, add that
value to the required thickness of the depth shim(s).
If the number is positive, subtract that value from
the thickness of the depth shim(s). I f the number is 0
no change is necessary.
After selecting the proper pinion depth shim (s),
remove the measurement tools from the axle hous­
ing.
