Is this called truing? Well, my friend tried to remove the real wheel on my bike to help me put a qr skewer for a trainer--well, it didn't work out and we just placed the wheel back on the bike. Trouble is, the thing is all wobbly now--how do I fix it?

Thanks

Probably, if you tried to replace the axle and it's just now "wobbly", the hub needs to be tightened. What sorts of equipment are you dealing with? What exactly did you guys do to it (or attempt to do to it?)?

Heh, well, we tried to take it off and kinda put it back on (in the dark). It's a crappy mtn bike. Basically it has a slight wobble to it when I spin the back wheel.

Is the rim "bent", or does it "wobble" from the hub? You know that there's a slew of material about to be read on the internet about these type of things. I would first try to re-seat the wheel about the dropouts, and also check to see if the tire is seated properly on the rim.

I'll throw out a guess that you loosened your cones. Easily fixed with proper tools but I've never done it myself. (haven't needed to)

You are right and I have looked on the internet, but I thought asking might be better.
