there must be some play in the hub . and when skewer is done tigh everything compresses and it can run freely .
Hi there- someone else drew my attention to thsi post- so hopefully I can help.
I think that Chris is pretty near the answer, on two counts.
ONE- I have seen a few hubs where the freehub body hasn't been pushed fully home in assembly (remember these were built by people rather than 1000 pieces a minute type machines). Check that the nut on the axle is tight. Chances are its on with some sort of loctite, so you'll need to undo the nut, and then do it back up again.
TWO, the ratchet ring in the body is a tight fit at best, and isn't always tightened down- again, as it was a hand assembly operation (all be it with production tools). The ring is screwed into the body. It isn't always screwed in all the way. It was hard to assemble on the bench, compared to the mechanical advantage implied on the drivetrain by pushing a 24/32t gear up a hill. This is I think where the improvement to your hub may lie.
You have the wheel built, pop on the cassette, and stand on the cranks. Any luck you shoudl get another 1/4 turn on the ratched ring, and all the bearings should hunker down into their locations.
Bear in mind now that the axle nut will again now need a little tightening, and also if you mech stops were set, the whole asembly will have moved inboard a tiny amount, so re-check your gear setup.
The ratchet ring tightening a little happens on all hubs to some extent when first ridden. The tight tolerances of some designs though means that some designs of hubs need a little more bedding in than others. I'd be pretty sure that this is it.
If you get real stuck, drop me a pm- I'll do my best to help. I have all spares for this hub if needed
