Product review (5 stars): Don't wait to replace these (BTDT)
Did the job for my Sears Kenmore HE2 dryer. Old wheels had worn down A LOT and eventually started making noise. The noise wasn't in the wheels or bearings; it was from the drum sagging down (due the reduced radius of the wheels) onto other parts of the dryer and rubbing. If/when this happens another six or seven years down the road, I'm gonna replace everything immediately when it starts to make noise, and not wait too long -- like I did this time.
