How do I remove my steering colum?

We must be talking about two different things.

The coupler I am talking about is the piece at the end of the steering column that acts as a u-joint to allow some miss alignment between the column and the steering box. It has a serrated hole in the end and slips over the serrated shaft coming out of the steering box. There is a roll pin that goes through this coupler and interlocks with a matching groove in the shaft from the box.

This pin is what holds the coupler to the box and if you do not remove it you can't remove the shaft without pulling the guts from the coupler as I mentioned.

The pin is a split tension pin and it typically takes very little force to drive it out, certainly not enough to damage seals or bushings. I have done a few of these and have not had trouble removing the pin but I have had trouble getting the coupler off the steering box because of rust.

Here is a link that shows the parts of the coupler. http://www.mopar4sale.com/tsb1.htm
