Do they have ball bearings? If they do pull the seals off and clean out the bearing and repack it.So I have had GX AXS on my trail bike for a couple months now. I love it…except for one annoyance. The jockey wheels on the derailleur get squeaky every couple of rides. It’s obnoxious. I am 100% sure its the jockey wheels as when I remove them, clean, lightly grease, and reassemble they are quiet…for a ride or two until the noise returns. I have neglected my XO1 mechanical derailleurs for weeks on end and never had a single noise. What gives with the GX AXS? Is this common? What can I do to prevent this?
