The worm has a built in spline that fits into a groove in the shaft. The worm is supported and the shaft pushed out toward the wheel end. As I said earlier, a short driver is needed to miss the key in the worm.
I would not expect the bushings in the housing to be bad. I have not found any needing replacement.
I would get a driver made so not to deform them. They probably would need sizing after installation. You might think of taking it to a machine shop.
