Re: Steering Problem
First off, look underneath while someone turns the wheel and see if any of the steering components are hitting something (like a header).
My other main thought is that the Pitman arm on the steering box may have been incorrectly installed onto the steering box. I can't recall if all Pitman arms are indexed, but I seem to remember some in the old days that were not indexed, thus you could install them off-center.
You could try this (assuming nothing is actually hitting the steering linkage underneath) - take Pitman arm off, then rotate steering wheel all the way to right and then back to left, counting turns from right full lock to left full lock. Divide by two, then hold steering wheel (turn ign key off, wheel will lock) in that position. In other words, if you had three full turns from lock to lock, then you would rotate wheel 1.5 turns from either lock and hold it in that position.
Then, with front wheels pointing as straight as possible, re-install Pitman arm securely to steering box. That should get you pretty close. You could then have it aligned by shop to get perfect setup.
Hope this helps.
