Our DT Swiss rear hub has developed a fault. It got us to our destination on Friday but we accepted a kind offer of a lift home rather than risk it failing completely and leaving us stranded. I've not stripped it down yet but I suspect either the axle or wheel bearings are in the process of failing (I suspect the axle). My plan would be to replace the axle and bearings, but by the time I've bought the parts & tools I wonder if it would be more cost effective and give greater reliability to replace the whole thing? I'd probably replace it with another the same unless I can find something better. I've read the DT Swiss technical manual but it's not clear if the ring nut needs to be removed to replace the drive side wheel bearing on this model (which requires a special tool). Anyone have any practical experience/advice replacing the wheel bearings or axle on this model of hub? Thanks, A.
