Product review (5 stars): Highly recommend
This was exactly what was causing my washer to "whine" when spinning!  Install was easy, as they provide very good instructions with pictures to help you along.  I did not spend the $80 on the special tool.  In stead, I purchased "all-thread" and washers (5/8" in size) to make my own.  Required a second person to hold a wrench on the tub side, but that was well worth the $65 in savings!

Washer works like new!
