How do you change the worm gear on the stearing shaft? does it need to be heated and than knocked off or should it just knock off?
 
Put in press & press off, The DVD ,s avalible show how to fit new one by threading inside of shaft on a 2 tooth & use a bolt to pull new worm on, If using a press to fit you must grip the shaft near the worm end or it will bend, Just used the bolt type puller on two & work well. Just my 2 cents worth,
 
This takes a special setup in the press to avoid damaging the shaft. I recommend finding someone who has such a setup, or sending it to Bratton's and paying them to do it.
 
Thanks guys im going to try doing it my self first. I have 3 columbs that the threads are broke off and I can practice on them before I do the good one.

To take off, I used a piece of pipe that the steering shaft could just fit into. I think it was 3/4" and a bit longer than the shaft above the worm.

Putting the shaft/worm into this pipe, I then tapped the pipe HARD on the ground until the shaft moved out of the worm. The pipe was the shoulder that the worm hit against. Inertia of the shaft carried it out of the worm.

Now going back together with a new worm I have not yet explored. The thread/bolt idea seems like it should work.

Thanks Joe; I'm going to try that next time.
 
I had a machine shop do mine. He got it off OK but he was not able to get it on all the way. There was about 1/8 of an inch short of all the way in.
Dont know if this is a problem.

It seems like that would make your steering wheel sit about 1/8" higher.
 
This is a fixture James Rogers made to hold the shaft while you press the worm on.

I have installed timing gears on crankshafts by heating the gear to about 300 deg in the oven, slides right on. This would probably work for the worm gear.
