Popping inside of steering column.
 

My steering column is loose, not the tilt part that everybody is complaining about (I fixed that already). When I turn the wheel, it pops first, then I can turn the wheels. At first I thought it was the rag joint, but I took out the shaft between the steering box and the column, put a screwdriver through the hole at the end of the column and rested it against the valve cover. When I apply pressure on the wheel I hear the pop, then I turn the wheel the other way so the screwdriver is against the master cylinder, and it pops again.

So it has to be something in the column itself, right? Any ideas what it might be?

This is really starting to annoy me someone out there has to know what is wrong.
