1939 Ford Steering Box

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.
 
You will need a press for some of the operations required to rebuild the steering box or the help of a machine shop. The worm gear is a VERY tight press onto the end of the steering shaft. A lot of times it is easier to cut the gear with a cut-off wheel and break it in half to get it off. Then you need to get the new one on! Believe there was a thread on the HAMB about a drop-hammer type of approach to get them back on. I would have to do a search as I don't (haven't had to yet) change out the worm gear if at all possible.

What tools do you have? You could use a lath to turn a driver to remove the bushings and another driver to get them back in. Bushing often require having a reamer run through them after they are pressed to size them correctly. It is really difficult (but not impossible) to work on some items without the proper equipment or access to someone how does.
 
Your socket idea will work.
Don't bother with the freeze.
Find someone with a Sunnen hone.

There is just the tiniest bit of bushing material to remove to get the shaft to fit. I would choose to have it a stiff hand fit... It will loosen up soon enough.

To change the worm gear, it's nice to have a press. You could remove it with a hammer.
It would be nice to have a valve guide type driver and a large vice. Substitute a bolt in the end of the shaft, you could even add a copper washer to the bolt... Use a large hammer and a punch in a vice grip to drive the bolt.

To install, put a piece of aluminum plate on the cement floor. Line up the keyway in the shaft with the worm gear, hit the worm gear on the plate with the shaft behind it and the shaft will be driven through the worm.

If you hit the worm with steel, it's hard and may throw shrapnel...

Thank You all for your ideas! lastly how difficult is it to remove the pin from the steering sector roller without a press, have not tried anything yet I'm looking at using a smaller diameter short stock of steel using a hammer to knock out pin, is that doable without to much effort or will it be a pain to remove?

I'm not overly concerned about removing those parts that where already mentioned as I have many tools including a oxy/acet torch , short of a press thou. I have rebuilt pumps seals bushings , bearings as part of my profession and have removed/installed many bushing before with and without a press. As I'm paying for a complete rebuilt kit chances are I'll be replacing everything.

Again thank you all for your effort in helping me.
