Keoke,
I had a wheel on a non-adjustable column that I "should" have used a puller on. The wheel was free on the splines for about 1/2", then refused to move further. I bounced it up & down for about an hour, tugged, pulled, hit the back side with a large rubber hammer.
Finally I was so mad that I cut the hub through to the splines with a cutoff wheel. It still wouldn't pull off. Had to make another cut & force the two halves apart with a chisel. There was a heavy burr all around the bottom of the hub splines which "might" have straightened out if I had used a puller. Anybody want a stock style wheel with no center hub? What ever you do, don't damage the shaft splines or it's very delicate threaded end.
A puller needs a mandrel to go down into the thicker tapered shoulder in the hollow steering shaft. The thread end of the shaft won't take puller pressure without damaging the thin end thread. Also, don't hammer on the nut. The puller needs to pull from the back side of the wheel as there is no other place to pull from. Kind of complicated, which is why I didn't use a puller in the first place.
And - That's why my car now has a new Derrington style wheel & hub. And likely, why the factory suggested a puller.
