Product review (5 stars): Repair took an hour from start to finish!
I consulted several online resources before concluding this part was the likely cause for no spinning and agitation in our old Whirlpool top loading washing machine. Part arrived super fast and repair took an hour from start to finish. This coupling is the "new" style and you will need a socket placed over the coupling and tap the socket's handle with a hammer to coax the part down the shaft. Very pleased with this--and other washing machine repair parts I have purchased on Amazon.
