More specifically it seems my XT rear hub has become really noisy to the point where it’s doing my head in and I need help!
I replaced the bearings in both sides (loose bearings on one side and in a race on the other) last year and all had been fine. Noticed a few weeks back a loud cracking noise that came from the back end when pedalling and traced it to the back wheel – I opened it up and noticed some of the free bearings weren’t round anymore. Cleaned out and replaced them with new bearings and grease – the obligatory ride round in the street told me all was good.
Next ride the noise was back but worse than ever…it’s an inconsistent noise and every now again there’s a really loud cracking noise. Opened up again today to find tiny flakes of metal and the grease was really black after 2 rides (was red!). Also replaced BB so that’s not the source of the noise. I don’t think I’ve overtightened them so would rule that one out too 😕
I’ve waffled on a bit there but what’s the solution? Anyone had similar problems with Shimano cup and cone bearings?
Cheers
