Product review (5 stars): Solved the problem
My dryer is alomst 9 years old and started squealing on heavier loads.  This replacement kit solved the problem.  Took about two hours to put in.  Three areas took the most time.  One was that that the ball plate in the back of the drum was stuck to the ball bearing and I had to unscrew it from within the drum and then pound it with a mallet to loosen it.  Directions didn't explain how to do this.  Two was screwing the ball plate back on (this is the new replacement plate, not the old one) uses self tapping screws, requiring a good screwdriver and a lot of muscle.  Third was that getting the old glue off the the felt placement area took a lot of time.  Also be careful putting the ball into the ball bearing.  It helps when you lube it first and then it will stick until you mount it.

Machine works great now.  The big thought I had is why don't they put in a grease fitting in the back ball bearing?  This would solve most problems because the bearing wears out once the installed grease is used up.  Any one know of a dryer that uses a grease fitting there?
