When ring and pinions are set up, the contact patch of the gears is ideally centered on the gear tooth like on this Sierra Gear gearset we got from West Coast Differentials. The pattern is checked with gear marking compound to mark where the teeth contact when the gears are rotated. Correctly set up gears will have a backlash between 0.006 and 0.010.
