Product review (5 stars): OEM quality - just thick strips of plastic
I'm horrible. I got these thinking the ones (I replaced) in my dryer had worn down (again). I was wrong - it was actually the rear bearing sleeve that was squealing - but since I had these on hand, I used them (one). But, before I did that, I did try these in their intended locations and they fit okay and seemed to be just as slick as my OEM ones.

To solve my problem (rear bearing sleeve) I cut about a half inch off, of one of these - basically a perfect square with the hole in the center of it - and got a lighter to soften it a little so I could use the shaft of a small screwdriver to roll it into a cylinder. I sawed the disintegrated sleeve part of the old bearing sleeve off flush with its face, replaced it on the shaft, and just shoved the drum until it finally slid into place. Zero play, no resistance, and we get to have clothes for the rest of the week while I wait for a real sleeve (just kidding, I have three more of these to use when this fails).

I feel like this kind of plastilube/longer-lasting pseudogrease should be used for more applications. It's very versatile stuff.
