The 128042 Eaton helical gear and bushing assembly is a differential driveline component supplied as a matched gear and bushing unit under Eaton part number 128042. Because the gear and its bushing come together as one assembly, the bushing bore and gear are paired at assembly rather than sourced separately, which keeps the fit consistent during a differential rebuild. Helical tooth form runs quieter than a comparable straight-cut gear under load. Eaton differential internals vary by model and ratio, so give us a call with your axle tag information and we will confirm 128042 is the right assembly for your unit.
