Sometimes you get lucky. I always disassemble them to look at the condition of the worm shaft. On several I have found the bearing surface to be bad through lack of grease or in one case contaminated with water. Since the worm shaft is the inner bearing race on both ends it will not help to install new bearings against a worn race. If the bearing surface is bad I send them to a rebuilder.
