I must deal with better quality hubs. Many feel slightly tight when new and there's a temptation to adjust. But when I do, I find them to be loose after break in. OTOH, if I leave them alone, they break in nicely.
In any case, I asked because the OP was having problems that usually happen after a user rebuild (displaced seal, extra or displaced ball, etc.) so I felt I'd gone as far as I could based on the info provided so far.
Had the OP found the hub tight and just slightly loosened it, then he wouldn't suffer the range of issues one might after a rebuild.
