Dumb question, is there a trick to removing the roll pin from the door hinge friction pad? Seems simple enough, just drive it out. I finally got mine to move, and I can drive it up or down, but only about one inch. Then it comes to an absolute dead stop. Have tried several times with identical results, driving it down or up, doesn't matter. One inch and stop. I swear, there are times this truck makes me feel like the village idiot.
