Hi Ken,
I've never had one apart, but I think you need to take the slack out of the table bushing before adjusting the worm/table wormgear play.
Once I had a worn tapered bushing in B-C hob. We carefully machined off some of the bushing's thrust face to shorten the bushing and this brought the shaft-bushing fit back to OK.
With regard to the worm/wormgear: there can be backlash and worm end-play. Once the table bushing is fixed, you'll want to adjust both backlash and endplay to near-zero. Not zero, because as the pair heats up, backlash and endplay will reduce and could cause binding. So you want to watch for that.
Maybe someone with more experience will add to this.
HTH
