Product review (5 stars): Finally the right support for the dryer!
I had purchased some other support wheels for our Kenmore (Whirlpool) dryer when the originals wore off.  They were not OEM and went bad in <2 months.  These wheels are great and have been working really well for the past several months.  The overall build quality and the quality of the rubber was clearly much superior to the other brand (cannot remember now, but the wheels were red in color).  I strongly recommend it to anyone who is trying to fix their noisy and malfunctioning dryer.
