Product review (2 stars): Just what I was needing - I just wish they were higher quality.
Update: It's been a year since we installed these and the dryer started squealing again a couple of months after installing them. Now I have to replace these again. It now squeals and thumps. It has the classic sound of a shoe tumbling around in the dryer. I guess the wobble meant they weren't really true and these were manufactured poorly.

These worked just fine. It took me a while to get the dryer into a position where I could take it apart (I wish I would have just left it on top of the washer from the beginning, pulled it forward to remove the lower access panel instead of moving it to the floor). but, once that was done, replacing the parts was pretty easy. The most difficult part was figuring out where this random felt noise dampening pad was supposed to go. I ended up sticking in between the drum and the wall. The only reason these are four instead of 5 stars is because there's a little flashing on the wheels and they don't seem to be completely true - they wobble just a bit. This makes the noise of the dryer louder than it used to be, slightly, but much better than when it was screeching at me. The screech is why I purchased this item in the first place.
