Rear Wheel Problem

[Broken Spoke]

I ride a 99 CR250. This past weekend I crashed, but nothing violent. I got back on my bike and rode it to my truck, which was about 50 yards away. When I got off of my bike, I notice side to side movement in my rear wheel. I first thought it was the bearing, but after looking closer, all of my spokes are loose, but the bearings are fine. What would cause this?

My second question is how do I fix it? I know my way around a bike pretty well, except for wheels and spokes. Should I be able to turn the nipples freely with a wrench or will I have to hold the spokes with vise grips? Will I have to remove the tire?

Thanks for any replys.

it sounds like your rim is bent. is the whole wheel moving, like where is bolts onto the swing arm? or does it feel like the rim? did you case it on the top of a table or what? yes you might have to remove the tire. take it off and examine it closely. you might end up having to replace the rim if you bent it.
