68 steering issue

OK it's been a while, but I haven't bailed yet. I moved the Mustang for the first time in quite some time the other day, and it seems like it won't turn right. It doesn't turn very well at all, but it really won't turn right. Like, 3 point turn to get into the driveway.

Here's what I know about it. It has factory power steering. Some components are 71 Mustang, according to the POs restoration log -"68 brake lines and lower control arm, everything else is '71 - rotor, calipers, bearings, tie rod end, pads"

My buddy told me to take it to an alignment shop, but I don't know of one that I can get to only turning left, so I figured I'd ask here first... Any help will be appreciated.

It's the hydraulic cylinder attached to your PS setup by the control valve. 

Has two small hydraulic hoses attached......

Re: 68 steering issue

I found a power steering control valve rebuild kit in my spare parts, should I go ahead and rebuild this thing? I feel like there's a way to troubleshoot and figure out if that's necessary, but I have no clue how...

Re: 68 steering issue

Why don't you remove the PS RAM off the car first since you may need a new one or need to rebuild it. Then look and see if removing the RAM Fixes the problem. If it does then your problem is the RAM.

Re: 68 steering issue

I don't understand. Are you saying I can drive the car without the RAM installed?

Re: 68 steering issue

your ram is what steers the car, so what I think he is saying is if you disconnect the ram from your steering but leave the lines attached you will be able to turn your steering wheel & the ram should go from being all the way in to all the way out, if it does then it slid where it should be bolted in place. I hope this helps & explains things alittle easier.

Re: 68 steering issue

Check to see if the steering box linkage centers the center link when in mid travel.

Re: 68 steering issue

I'm clearly in over my head here, as I haven't understood any of the advice given to me. I don't trust any of the shops around here, my go to guy doesn't work on old cars. Can anyone recommend a shop in the Charlotte NC area? Or better yet, someone local that can come fix it?

So this means when you go full left or right the box should re-center and go back to the middle. Youre center link is equal length from side to side so that you get the same amount of turning when turning left or right. If the center link doesn't center there could either be a problem in the ram or the box.

If I was you I would look up some steering 101 videos on the mustangs or similar cars. This would really help to explain parts.

As far a steering rebuild service you may want to call up Dan "Chockostang". He rebuild the old for steering parts. He also had new ones available for purchase.

Re: 68 steering issue

Still don't quite get it, and all the videos I can find are related to EPAS. There is a video on rebuilding the control valve, which I feel like I could do, but I don't understand all the other stuff. Thanks anyways guys, I guess I'll roll the dice at a local shop.

Re: 68 steering issue

HAS, you have a power steering car.  This is basically a manual steer car, with a pump and ram to assist with the effort.  If you disconnect the ram for the "center" or "drag" link, you will be temporarily putting your car in "manual steering" mode.  It will function as a manual steer car.  If the car steers normal, you know the ram is the problem.  If the car has the same steering problem, there is a different problem, other than the ram (you may still have a ram problem, though).

Here is a link to a past post relating to similar issues on 65/66 cars.  About halfway down the various posts, (reply #8) MS gives great, simple, detailed step by step instructions for initial steering components setup.  Read his instructions several times, and familiarize yourself with what the various parts are (inner & outer tie rods, adjusting sleeves, etc.), where they are located, and what their function is, and how they interact with each other.  You will eventually understand how the geometry works.  If you actually perform the steps that MS explains in his post in the link below you will have a good initial point for an alignment shop to dial it in.

I remember laying under my car years ago looking at all the parts, and how they worked together to move the wheels when the steering wheel was turned.  I'm a visual learner, and would never have figured it out by reading posts on the internet.  Hope this helps.

Re: 68 steering issue

Could you post two pictures?  One of each pair of tie rods, showing the position of the tie rods installed in the adjusting sleeves?  Seeing that will confirm or eliminate the tie rod adjustment ad a possibility.

A picture of the power steering ram and valve under the car might help, too.

Pictures will help diagnose an obvious problem.

This coukd be something oddball, like the pitman arm hitting headers, or something improperly installed, or the wrong parts.

Re: 68 steering issue

I think I see your problem. The cylinder drop bracket appears to be pulling out of the frame. This could account for more travel 1 way.

Nevermind, converting to manual steering.

Re: 68 steering issue

So instead of converting to manual steering, I bought a new drop bracket and welded it to the frame. It made an improvement, but it still turns left better than right. Any other suggestions? Thanks
