the lower half and upper half of the column have a protrusion on the left and right sides. These protrusions each have a hole in them to pivot on. The holes are around 1/4" to 5/16" diamiter and only 3/4" long or so.
The two pins have a hole tapped in the center of them so they can be pulled out.
I made a "puller" out of a long screw or stud, and a spacer made out of a 1" long piece of 1/2" ID tubing with bigger ID than the pin.
I screwed the screw into the pin, placed the spacer over it, placed a washer over the screw, and placed a nut on the cut off outer end of the screw.
I then tighten the nut to pull the pin out.
It's quite a job to get in there to do it the first time. It requires patience.
Either the pins are loose or I've heard there are three screws behind this area that come loose.
Probably this comes from using the steering wheel to pull yourself out of the seat.
