The coast-side pattern is closely examined to make sure that it's also in the center. If either side has a low or high contact pattern, the pinion shim thickness has to be increased or decreased accordingly. A low pattern indicates the pinion is too close to the ring gear, and the shim thickness has to be reduced. A high pattern indicates that the pinion is too far away from the ring, so the shim thickness has to be increased. It may only take 0.002 or 0.003 of shim adjustment to correct the gear-contact tooth pattern, but failure to have an even pattern in the center of the gear often results in either noisy operation or the ring or pinion shearing a tooth. After verifying the pattern, a grease and wax remover is used to clean the yellow marking compound off of the gears. View Related Article
