I have a 2008 iron horse mklll, I was on a ride and I heard a creaking noise. I have determined that it is coming from the rear hub. I have looked over the hub there are no cracks, So I pulled the axle and looked at the axle and the inside of the hub and everything looks fine so I put it back together. The noise went away for about 1 mile af riding and now its back. Does anyone have any idea what this could be ?
I cant find a name on the hub , All it says in the specs is alloy hub on the ironhorse web site.

Thanks
Phil
