My truck has this "tick" in the steering wheel. Dont have any specific time to do it, but notice it more in wind. Dont do it more or less over bumps, or smooth road. It could do it on a smooth road and when I get in bumps it may stop, though the truck does feel unstable on bumps and in wind. Last year I changed the upper/lower ball joints, inner tie rod ends, all 4 shocks and sway bar end links. The new end links arent looking to good either, not really worn, the bushings are still there but the end link looks like it could use some tightining up, but I figure if I am going to mess with it again I just assume put a new set on. I just replaced tires about a week ago thinking one of the tires were bad but it still does it. Just replaced the rear shoes and drums and probably have a warped rotor from the problem that was taking place back there. I checked out the tie rod ends and ball joints and there is no play in those. Would a warped rotor or the sway bar links cause this? Truck is a 97 F-150 2WD with M5OD.
