Product review (5 stars): Perfect Fit on my Whirlpool Washer
There are great how-to videos on youtube for replacing this coupler, which makes the task straight forward and quick.

This part looks like an improved design. Shipped quickly via prime. Amazon + prime shipping + how-to videos makes appliance repair easy and convenient.

Some advice (one bandage later): Wear light gloves when installing this because the sheet metal edges are very sharp.
