How do you remove and install the cotters? Do you have the BikeSmith tool, or do you use something else? Like you, I suspect the cotters first. Possibly if you take out both cotters and reinstall them the other way, that would change something.
Possibly a chain ring bolt is loose? If the spider is suaged to the right crank arm, it might possibly be coming loose, which would be bad.
Possibly the squeak is coming from the chain?
I use a hammer to remove em, and a hammer to install em. Matter of fact its the same hammer

I'll try turning them around but I seem to recall that the left cotter only wanted to go in one way, which sorta mandates the direction the right one goes in.
Whats "Suaged" mean? whats the other option if its not suaged?
