Product review (5 stars): FIXED THE UL ISSUE---EASY INSTALL
I had been battling the well documented UL error message at the 12 minute mark.  Frustration had set in.  I spoke with an appliance repair guy and he said to just replace the upper ball joints with the retrofitted two piece replacement and that should take care of it.  IT DIDNT.  Wasted 25 bucks and should have just gotten the whole suspension rod unit. I easily installed the rods and was ready to go.  I could already tell that the tub bounced less.  I loaded up the unit with towels and let her go.  NO THUMPING, NO NOISE and NO UL ERROR MESSAGE.  This is the fix.

I tried to source the part locally...75 bucks.. and the appliance counter guy said that you most likely need bearings as well.  He wanted to come out and fix it.  NO THANKS.  Quick shipping and installed that afternoon.  PEACE in the laundry room.
