If you allow .002 clearance per bearing surface and there are two surfaces per bearing, that says you can move each bearing .004". Since the bearings are well inboard of the shaft you will see double the movment at the end of the shaft.

Two bearings.. get even more movment.

Bottom line? .022" of movement at the end of the shaft is pretty normal. As long as the wheels have not rubbed the housing your probably OK.
