Ok, so I have that ominous creak in my crank everytime i peddle, and now that I have pretty much eliminated my pedals as the source, I now have to (I think) take off my entire crank and clean and inspect it. Im not even sure what to look for once Im down there, but I know that getting the thing off of my bike is the first step.
If any of yall could help me out with some tips for how to take the thing off, and what to look for once it is off, Id appreciate it.

What model crank do you have? Most likely you'll need a crank puller. www.parktool.com has the step by step instructions.

Have you eliminated other common creak spots? Is your seatpost tightened? Your cleats tightened? Stem/handlbar bolts lubed/tightened? Skewers tight?
I ask this because on my new bike last year I could have sworn that the creak was coming from the drive train so I removed/reinstalled the crank/BB to no avail. The source was from a loose seat post.
As the previous post recommends, tell what crank you have and also reference the the Park Tool site.

Something worth mentioning is that on double suspension bikes, the pivot bushings will occasionaly also cause creaking. When that happens, they need to be cleaned or replaced. The easiest way to check to see if this is to blame is to take your foot and press into the side of the frame right on the bushings. If it yields a squeak, the bushings need help.

I agree with SaddleBags and Michigander...I'd say your crank is probably the last place to find a "creak" as it is a fixed object that moves with the spindle in the bb...so, unless there is some strange damage to it (which you would have already seen) look toward your moving parts first...(everything mentioned above).

Oh, yeah tools--while worth every penny--are expensive for people not totally serious about cycling (& repair)...just a thought.

Right on... thanks a lot. I dont have any suspension on my bike (its a road bike), but thanks anyways. Im going to tighten everything, then if that doesnt work, Ill still look at the whole crank/BB area, just to see if there is anything obvious. Thanks a lot guys

Hope you find the noise. Do a search on 'tick', 'tic', 'creak', 'noise' in the mech. forum. You'd be surprised how many people post on this site looking for help for that annoying creak.

Hey just to let yall know, I figgured it out. it was my toeclips, they were just a bit loose on the right foot, everytime i was pushing down, i was rubbing the plastic up against the metal nut. I just tightened the thing and rode it around the block real quick... problem solved. Thanks for all of your help guys... as always, I appreciate it.
