Product review (4 stars): Factory original parts - saved the purchase of an $800 washer
This driveshaft cured the leak underneath my washer.  After 7 years of daily use, the old one had worn enough to leave seal grooves on the mating surfaces on the shaft allowing the drum water to leak through to the floor.  I installed it without getting the special tool that sells for $85.  GET THE TOOL and sell it on online for $75.  Its worth the time saved and someone will buy it online and do the same thing.  I was able to use the old shaft to seat the upper bearing in the tub.  The lower bearing was a little trickier but can be done.  Amazon appliance parts prices are half the local retail pricing I shopped.  Savings on this part alone was half my Amazon Prime fee.
