Aside from Oakleaf's old thread about ceramic bushings in jockey pulleys, I couldn't find any general info here about taking apart, cleaning and lubing them. Mine were singing quite a song today, so it seems they need to be done. I've googled directions and it sounds relatively simple. Before I take this next fumbling step in increasing my bike maintenance repertoire, though, I thought I'd check whether anyone here has any good tips or advice. DebW? Anyone?
