Mine had the same problem. I believe it was accelerated by the previous owner hoisting himself into the rig by grabbing onto the steering wheel, and pulling his fat arse in.
The fix is easy, but it's the disassembly that causes the headache. As you probably know, there are some inverse Torx head bolts about halfway down the column that get loose and cause this issue. Amazingly, there are no lock washers or lock-tite used on them from the factory. When I did mine, I applied some lock-tite and tightened mine down. Totally resolved the issue. Reassembly was a bear. Lots of trial and error, but when it all went back together, the moment was "MAGIC".
I have a gaggle of pictures of the process when I did mine, but I did it so long ago, that I don't remember the actual steps in the process. Another user here had a pretty good write-up of the process, but I can't remember who it was. I might have the procedure he sent me somewhere on my computer at home...I'll have a look-see when I get off of work, and will send it your way if I find it.
To do the job correctly, you'll need some special tools....
1) Steering wheel remover (available at Kragen-type parts stores reasonably cheap. Sounds like you've already got yours off though.)
2) Security Plate remover (this is a device that presses down on the star-shaped security locking plate, and allows you to remove it. Also avaiable at most auto parts stores)
3) Tilt-column pin remover (simple little cheapie tool to pull the pins out of the side of the column. Got mine at Napa for $5.)
P.S. The search feature didn't work for me either (as is fairly typical). I posted a message about this, and received many helpful replies. I believe the board only displays information for a finite amount of time.
