Product review (5 stars): Fairly easy repair. Saved a couple hundred $$
So far so good with this coupler. Have ran two loads through and have had no problems with the washing machine whatsoever. Was very easy to put on, just had to tap it in a little bit with a socket and a hammer and took very little effort to secure it on to the motor and washing machine basket shafts. I made sure the socket was same width as the metal piece in the middle of the coupler.
Original estimate to repair was $95 diagnosis and $125/hr repair. I completed the whole thing in less than 2 hrs ( including Murphys law screw ups in my part) and $20 in parts which  included a spare just in case something went south.
Had trouble getting the mounting clips to  secure to The motor until I discovered I was using the incorrect mounting spot. Once I moved the motor mounting clip over to the correct spot it was a piece of cake from there. I did NOT dismantle the washing machine case. Just tipped it on Its back and rested it against a couple of paint cans to avoid damage to anything on the back.
