Pinion depth and mesh basics
A ring and pinion set is the final gear pair that turns driveshaft rotation into wheel rotation, so every tooth contact affects noise, heat and wear. On a front reverse set, the pinion sits on the opposite side of the ring from a conventional arrangement, which changes how the teeth load under throttle and braking. Shops usually check the contact pattern with marking compound before the cover goes back on, because a pattern that sits too close to the toe or heel will whine or chip under load.
Old gears that have been run hard often show pitting, chipped tooth edges or a bright wear band along the flank. Pinion bearings and carrier bearings are commonly replaced at the same time, since a new set running on worn bearings will not hold its setup. Keep mesh checks and preload readings with the vehicle so the next service starts from known measurements.
