My old pedals were creaking a little. I think some of the bearings were broken or maybe the right pedal was cracked somewhere. They were plastic and fairly lite. I ordered some Diamond Back replacements that are metal and a LOT heavier, but they make for a solid feel while riding and the grips are excellent with my shoes. Ordered a pedal wrench. It is amazing. If you don't have one, it is worth the investment. Also, lubed the chain.
