Cured, I took the axle off and re-greased..... click be gone
I know Alex sells the new parts, but I thought I would have a go myself.....with a little help from Zugara. To be honest there was plenty of grease in the joints so I don't think it was that.
Zugara and I came to the conclusion that it was just the metal face that goes in the back of the hub that is the problem. We put a very light amount of grease on that as well.
I have been click free for a month now, and no problems. If it comes back then so be it, I will get a new part from Alex, but if it does not then I have saved myself £200
