Differential pinion-height gauge reading — nominal (NA6)

0 in (0 mm)0 mm {0 in}

Zero the factory gauge on its reference surface plate. With the specified pinion-height SST installed, measure the lowest left and right carrier side-bearing seating positions and average the two readings. This is the nominal factory fixture reading, not a physical zero pinion depth. Select the spacer closest to the required correction; consult the complete cited setup procedure.
