I have a 2010 Specialized Secteur Triple, and this is my first time working on a hub.
So for the past three months, I have heard a knocking from the rear wheel whenever I would go over a bump. I thought that it was simply chain slap, but after removing the chain, the noise was still present. I bought a chainwhip and lockring tool and took my hub apart last night. When I removed the axle, the freehub body just fell off - the fixing bolt was completely loose and bouncing inside the hub! It tightens from the non-drive side (requiring a longer 10 mm allen wrench).
There did not appear to be any damage (to my untrained eye) so I snugged it up as best I could, repacked the bearings, and adjusted the cones.
1.) What purpose does the fixing bolt serve? The bike seemed perfectly operational, but is that simply because everything else was tight?
2.) I adjusted the cones last night (again, first time) - now the quick release axle has to be extremely tight to eliminate side-to-side play. Is this the elusive point that the park tool manual wants me to achieve? Or would that suggest that the cones should be tightened more?
Once this is done, I'm installing my new, cheaply acquired ST-R500 brifters, so any help is appreciated so that I can get to the fun stuff. Thanks!
