Tighten the crank bolts first...
I've had clicking, squeaking and noises somewhere in between on my crappy splined Shimano LX crankset. Being 3yrs old, I'd asssume your bike has some kind of splined crank/BB combo. My clicks and squeaks came from the splined interface, tightening the crank bolts helped but didn't eliminate them. Replacing BB didn't eliminate clicks either. Along with shorter BB life, this is another "advantage" of splined cranks.MRhine5 said:
