I'm trying to get the old Liberator up and running again. The one thing that is stopping me from taking it on test drive is the tilt steering wheel being loose. It looks like the turn signal housing is loose (where it pivots for the tilt). The rest of the column is mounted solidly in the truck. Is there a nut that needs to be tightened? What would cause this? I've done several searches and looked through Chilton's to no avail. It's for a 1981 K5 with tilt steering. Local shop says they'll rebuild the column but I think something is just loose! Any help is greatly appreciated.
