6000 miles for a wheel set? Really? To say that surprises me is an understatement, my old mavic MA2's with veloce hubs on my winter bike lasted about 25000 before I changed them and that was only because I changed to the fulcrums on my bianchi and used the ambrosio's from there on the winter bike.
I can only assume I didn't press the bearings in far enough although they looked pretty well fitted to me. I used a piece of studding, a 20mm socket one end and a 21mm the other, the non freehub end needed the smaller socket, two nuts and washers. I fitted the bearings in place and tightened the nuts down so pressing the bearings in. I kept tightening the nuts as far as I could before I felt they couldn't go in any further without damaging anything. Looking through the bearing/hub the centre tube seemed in line with no gap, so it looked, as far as I could see, exactly the same as when I removed it.
Fitting the freehub was a bit fiddly but pressing two of the three pawls in with a thin screwdriver was enough to slot it home, there seemd to be a slight gap between the inner face of the freehub where the first sprocket sits and the end but that appears to be where the spoke protector would sit and i removed that at the time I fitted the wheels a year ago.
So I was pretty certain I had it all lined up and correctly in place.
I fitted the cassette sprockets and spacers exactly the same as I did when I fitted them to the wheel when I replaced the cassette earlier in the year, except this time it seems as if the lockring is sitting proud of the locknut.
When I fit the same cassette and lockring to the old wheel the locknut is further out than the lockring.
I'll try new bearings yet again!

SOrry I know its no help. I might have taken it to the LBS in the end so if you have no joy Ill go and ask him. THe tube between the bearings you say was loose in your OP, which it is supposed to be, is it still loose? If not it might be pressing against the bearings, even though its alligned?
..maybe.
huh, it all seemed so stiff. If i backpedalled, the chain on top slackened, turn the cranks by hand and there was a lot of resistance. pun the wheel, it just slowed to a quick stop.
