If it sounds like someone is hoarding squealing piglets in the laundry room on washday, then this item maybe for you!
Though I probably could have  gotten by with only the plastic bearing ( available separately), I opted to replace the ball-shaft as a complete set.  The chrome finish on the ball was extremely rough. I quickly polished it before installation with some fine sandpaper, and that seemed to work well. Though, I think I may have been as far ahead to re-use the original ball-shaft. All in all, now my dryer is happy and quiet. I no longer put off doing laundry in fear of concerned neighbors calling the cops!
