What Made My Dryer Squeak

I've noticed that a few people who've come here have been looking for information on what is making their dryers squeak. From what I understand, a couple of things can cause this. Either there's something wrong with the dryer's bearings (in my dryer's case, a screw was missing from one of the bearings and the screw in another bearing had come loose), or the drive belt is worn. It's a cheap, simple fix either way. The Sears guy who came to fix my dryer finished in five minutes and didn't bother to charge me.

Hope that helps.
