Centering Steering Box
Current dilemma: A have a later model 3.5 turn power steering box. problem is, 2 turns are to the left and only 1.5 to the right. This is not fun in parking lots where I have to turn right , but great when turning left.
I have thought about various ways to remedy this, but have run into problems with each idea. 1) Remove pitman arm and re-clock. -NoGo as the arm is splined only to be moved 1/4 turn. Too much. 2) I tried evening it out via tie rods. i.e. lengthen one side, shorten other. -Now one side is much longer than the other, not leaving much room for alignment adjustment. Ideally they should be close to equal and centered. It also causes the steering wheel to not be centered and the turn signal cancel not to function properly. I could remedy the steering wheel problems i think by loosening the column from the intermediate shaft and realigning, but that still leaves me with horribly uneven tie rod ends. Anyone have any other ideas? Am I missing something stupid? Thanks in advance -Chris

Re: Centering Steering Box
You have three issues: the tie rods, the pitman-drag link relationship, and the steering shaft to steering box relationship. I's start with a wheel alignment to make sure that your adjustments are correct up front. Your pitman arm seems to be a pretty blunt adjustment, so unless you've messed with it I'd leave it alone for now. Once the wheels are aligned you can disconnect the steering column from the steering box and "count the turns" to find the center point, then reconnect. I taped a coat hanger on the dash and marked my left/right stops, then counted turns until the wheel was centered. The shaft into the steering box has finer threads so this adjustment should work.
I don't quite remember the set-up, but if your wheel isn't completely centered after counting the turns you might take it off and reinstall it so it's even. Anyway, my 2 cents.

Re: Centering Steering Box
So, I'm assuming there is enough adjustment in the tie rod ends for the alignment shop to center the box. That will solve that problem, hopefully.
Now, if that works I can just unbolt the column from the shaft and line them up. Is the column/shaft splined and keyed or just splined?

Re: Centering Steering Box
This is how I do it. Disconnect the pitman arm from the center link. Turn the wheel all the way to one side. Count the turns exactly to the other stop. Return the steering wheel EXACTLY half; irregardless of the steering wheel position.
This is where the steering box is centered. Take a rope or something and hold the wheel there. Now you adjust the tie rods until the front wheels are straight ahead. It helps to have a bottle jack to raise each front tire. Put the jack as close the the ball joint as possible. You can get the toe-in pretty close by eyeballing down the inside of the tire. Line up the forward and rear inner tire sideway (like a site on a gun) and look at the rear tire tread. It will be close when about an 1/8 inch of the tread is visible. Adjust both sides until the look the same. It will be REAL close. Now if the steering wheel isn't centered, you can remove the shaft from the box and center the steering wheel. It would be easier to move the steering wheel and do it there.

Re: Centering Steering Box
Excellent info speedalert. That was the basic plan, then take it in to the shop to fine tune the alignment. I agree with all but centering the steering wheel only, that is where I am now and ended up with turn signal cancel problems.
Thanks -Chris
