American Motorhome RV Workhorse Front Hub Oil Seal w8000036 alternative 370150a

A heavy-duty wheel seal fitted between the hub and axle on trucks and trailers, sealing in the lubricating oil bath and keeping dirt/contaminants out. Spring-loaded nitrile lips maintain contact with the shaft as it wears, with a ribbed OD design that grips the seal bore so it can't back out once installed. Shaft diameter: 2.875" Outside diameter: 3.885" Overall width: ~0.5"
