Every internal part, including ring and pinion gears, clutches, and carriers, is subjected to a 100% inspection. To guarantee performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are hydro blasted to restore them to their original OEM finish.
