Bottom Bracket Help

I've been riding through some snow, ice and salt all winter so far. Today my bottom bracket started making a sound like it's rubbing metal to metal with no grease. It still spins okay so I don't think it's completely shot, anyone I haven't taken it a part yet to look at it. Should I pull my cranks? If I take my back wheel and chain off and just spin the crank arms it doesn't make a noise at all. Maybe I need a new chain or just need to clean it? Any advice?

Did that spinning slow down on its own? Or did you use your hand or a brake? If it stopped on its own, your chain is too tight.

It slowed down on it's own and my chain is slack right now. Any more and it'll pop off if I go off a curb. I'm thinking I should go buy a new chain tomorrow.

You might remove the wheel and check the wheel bearings for free turning.

Thanks for all the help gentlemen, I cleaned the heck out of my chain and lubed it. Took the back wheel off and adjusted the hub and it's spinning for days now. It's still noisey but what can I expect after riding through winter gunk, I'll worry about cleaning everything down another day.

IF the wheel bearings were so tight that they were binding, I'd replace them.
$3 worth of bearings & grease may save you a hub in the future.

I can do that, i'll try to find the bearings online and order some then repack them.

Why not just spend $2 at your LBS?
In fact, spend $4 and get the fronts too.
Do the front 1st for practice.
Should be
20x 3/16" front
18x 1/4" rear
