Okay, I didn't know it might get this in-depth.
So, let me bring you up-to-date on this truck, to the "best of my understanding".
It's a '67 Chevy C10 SWB. The entire front end and Steering Column is out of a later model automobile. Whatever the steering column came out of had Cruise Control and a Tilt-Wheel. I can also "steer it" with one finger. Very nice indeed.
My mechanic already rebuilt the front end, replacing various worn parts such as tie rods, and adjusted everything, and aligned it.
That's when I realized the problem I'm having with the steering being "out of center", or whatever the proper term is.
He thought that maybe the gear in the steering gear box might be twisted, so he put in another compatible gear box from a '73 Chevy PU. That didn't do the trick, so he tried something else, which also didn't work.
He was acting a bit befuddled yesterday afternoon when I talked to him. That's when I came in here to ask for advice again.
He's got it driving really good, believe me.
The problem I am having is that it simply doesn't turn to the Right as good as it should, but I can make a U-Turn to the left without any problem.
It just seems to me that if the Pittman arm was moved to the left on the gear a spline or two or three, that might help the problem, or even solve it.
Also, I haven't "heard" any evidence of anything rubbing while making any turns.
BTW, I plan on keeping my mechanic. He's really good, and a very good friend to boot. Maybe he's just "thinking too hard" on this one? LOL!
I have that problem on my own job on occassions.
Thanks to all for your time, the suggestions, and the advice. I'm pretty much a dunce at auto repair, but very eager to learn.
Buying this old Chevy Truck is probably the best thing I've done in years. I am "hooked"!
