Product review (5 stars): Perfect replacement for my Kenmore He3t branded Whirlpool
My Kenmore branded Whirlpool dryer had a very annoying loud squeal.  I took the dryer apart and re-greased the existing bearing-less wheel, cleaned out and then re-assembled the dryer.  It was quiet for a few weeks and then began squealing again, but louder this time.  I bought this part, the arm with new wheel included and installed it.  Dryer has been silent since.

Pretty easy to replace.  Second time in, with a powered nut driver, it took about 20 minutes to swap out the part.
