The squeeky derailler pulley gets the grease
My cross bike recently developed a mean case of squeak. I figured out it was the derailler pulleys. They get pretty wet and dusty, so I can't blame them. To pull them out, I first removed the chain (since I've got a SRAM Power Link this is easy, can't recommend that enough) and undid the hex shoulder bolt (shown in the picture below). It's a Shimano Deore derailler, by the way. I figured that I'd have to lube the bushing, but after messing with the parts, I figured that the cause of the squeak was debris and a lack of lube between the side plates (silver discs shown below) and the pulley. I greased those, slid it back into the derailler, tightened the shoulder bolt, and removed it's brother. Only do one at a time unless you want to also disassemble the derailler cage.
