Need Quick Help W/ Steering Column

ok. I know about linear tension on gm columns and the need to pull the shaft to get a snap ring placed.
If you haven't got that pin out yet, lets get serious. Measure the distance from column shaft to door panel. Cut a piece of wood to go between there.
Open the door and place cloth or something on the door to protect the paint.
Push the door closed slowly with the wood against the column shaft. This will reduce the movement of the shaft when you strike the pin. Try not to mushroom the ends of the pin. Once it is out check it with a file before driving it back in. Hope this helps.
