Need help - need to replace the ignition "actuator"? It broke when it was freezing outside and i tried starting the bronco. i have a tilt wheel. I have the turn signal swith off and the ignition part of the column. I can see where it goes but can't get to it without pulling the next part of the column off - i need to pull the part with the bearing in it but i'm not sure how it is attached. I see "looks like a screw hole" on each side where it attaches to the part below - is it pressed on? do i need a special tool? need help
