About a month ago, the Nexus 8 hub on my winter bike broke. I put it aside since it was the end of winter and I finally quit playing with my new toys and decided to take the Nexus hub apart.
To make a long story short there is a lot of side to side play although the axle is not broken. I do see something like a retaining clip loose on the inside of the drive side seal. I suspect that is the problem, or a symptom of a larger one. The whole mechanism rotates quite freely and easily around the axle and there doesn't seem to be any contamination from water. The grease itself seems to be pretty clean, which is great after 4 years. Anybody got any experience with this?
