Product review (5 stars): We Have a Screamer
My dryer was screaming like a banshee walking on hot coals.  Then my wife started screaming like a..... well u know the story.  It took me about 2hrs since I've never taken apart a dryer before.  Very simple and not much there.  Use your phone and take pictures for reassembly.  Use all the grease on the ball socket.  The whole kit was a tad more but worth it.  The money u save can now be spent on something truly unnecessary.
