Hy Pat66, I think the number you have given us from the axle is one digit short, the closest part number I can find is 3852520. That axle is a 5000 lb. axle, the o.e.m. p/n for the inner bearing assembly is 9418273 which translates to Timken/Bower p/n 3578A - 3525, the o.e.m. part number for the outer bearing is 457043 which translates to Timken/Bower 15103S - 15243, I hope this helps.
