Aloha,
I was able to remove the worm gear from the steering shaft using a sliding pipe.
However at first nothing moved, I then saw that some part of metal were embedded between the worm gear and the shaft groves (at the steering wheel end). I removed all the small piece of metal then I had to push the worm gear tighter to the shaft in order to remove the worm retainer clip which was kind of embedded under the worm gear (is that the case with yours?). I clear the retainer clip and removed it and then slid the pipe down the shaft and was able to slide the worm gear off, fairly easily.
Now I am facing the problem of removing the bushing inside the steering box.
I have made a jig and will try in the next couple of day to remove the busing.
Will let you know if successful.

In short make sure that the grove on both side of the worm gear are clean.
