Washer noisey during spin dry

Had wife balance washer on front edge while I accessed working parts from bottom of washer. Removed drive belt and turned agitator pulley, transmission pulley and drain pump pulley by hand. Drain pulley hard to turn and shaft had play in it. Ordered new drain pump and replaced upon receipt. Very few fasteners to remove and replace pump assembly. Drive belt was easy to remove and replace. Recommend also replacing drive belt on a washer this old.
