So I searched google and the forums before posting this question, but didn't find anything that helped.

I purchased a gently used Cycleops Fluid 2 trainer back in late December, because it's been a really hard winter here. I've been getting a lot of use out of the thing, and while it doesn't compare at all to the road, it keeps me in good enough shape. I haven't had any problems whatsoever with it, but during my workout yesterday morning the trainer itself started making a strange noise. The noise sounds like something on the trainer is unstable. It's almost as if something is loose, and is rocking back/forth while I'm riding. I can't quite figure out what it is, or what could possibly be loose on the trainer... I need someone to ride while I watch. Has anyone had this problem before? I'm kind of worried, because I don't want to have to get a new trainer already...

Thanks, appreciate any help!
