Guide Pulleys

2 teeth on the guide pulleys on Deore LX rear derailleur appear to be holding onto the chain cause it to skip. They do not appear to be any different than the rest. I found this after replacing the chain and cassette as well as front rings. The derailleur was replaced 3 years ago and seemed to be in fine shape. Should I just try replacing the guide pulleys? They really don't appear very worn at least compared to pictures I see of worn pulleys. These are ceramic pulleys if that matters.

Are you sure it's the pulleys, and not that the RD is too close to the cassette or something similar?

Before replacing them, dip a paper towel into some solvent and pinch the exposed part of the pulley as you run the chain to clean it. Then take a good close look for a nich or chip that might be the problem. Also make sure it's not anything in the chain.

Also check to make sure all the chain links are free. A tight link will usually reveal itself when running through the rd. you can loosen a tight link with a chain tool.
