Hubs and hub bearings seemingly continued to get overlooked, or under-looked, on new and old bikes these days. What most do not realize is that the quick release lever has a hand in the final bearing adjustment. So after setting your adjustment, it is easy enough to qualify it's quality by slipping a box end wrench over the spindle end and clamping the QR lever with the same force as you plan to use when on the bike. I have cut off an old rear dropout to be used instead, works the same. The rear dropout is thicker than a fork dropout, so is easier to use. What you will find every time, although to different degrees is that the hub should be left a little loose so the QR finalizes the adjustment. As long as there is no play once clamped, and the hub rolls smooth and fast, and you are ready to fly. While the hub is loose, I recommend pulling it completely apart and regreasing with a slippery Teflon grease, being positive to lock the drive-side of the rear hub upon reassembly. If the locking of the drive-side is overlooked upon reassembly or during the assembly process itself, the hub will not be able to hold a solid adjustment, and will continue to readjust itself with use.
