Product review (5 stars): Perfect for Maytag LDG4914AAE
Installed it on my Maytag LDG4914AAE and it is still perfect after a couple dozen loads of laundry.  It made a moderately loud whirring sound for a few minutes after starting it up for the first time, but that went away and now the dryer is running perfectly.  (It must have been rubbing a bit on something?)  Note that while this did come with the small clamp to tighten the wheel on the shaft, it did not come with a replacement horseshoe clip that goes on the end of the shaft, so don't lose or damage your old one.  I recommend getting the tool specifically for dealing with those clips - it will make the job a lot easier.
