steering geometry question

if you move the tie rod and drag link closer to the center of the knuckles it would create a greater turning radius right? but it would also cause you to turn more with less movement of the steering wheel right?

would it make it turn so quick that it would be unstable on the highway? I am afraid that if I move it in to much to get my turning radius back that it would turn to quickly on the road at highway speeds.

anyone have any experiences with this?

What exactly are you planning on doing?
I changed mine somewhat for the high steer arms I made.

It does not make enough difference to make it unstable.

But make sure whatever you do - do it safely, steering that works is important to have ;-)

yea that's why I want to check.

I just put new steering arms on my front 44. I had them drilled for chevy ends but ran out of funds before i got the steering linkage. so what I was going to do is take the stock drag link and tie rod and just move it to the steering arms. the matching holes in the steering arms that I will be using is about .5"-1" closer to the knuckles.

I will be running a high steer T setup when it's all said and done now instead of a cross over setup.

just wanted to make sure that move the tie rod back to the knuckles a little isn't going to make it unstable. this is still my DD and with 35s D44 F&R and 4.89 is actually does great for a DD.

I just want to keep it that way.

I have tried to be as safe as possible. I ahve followed billavista's page as much as I could. and using conical washers to attach the arms.

here is where the new hole is:

Sounds like it should work to me. Drive slow for testing

If you don't have hydraulic assist then moving the drag-link closer to the pivot of the knuckle will make it much harder to steer as you lose a lot of leverage.

I had mine mounted close for a while to have wicked tight steering but ended up moving it out further on the arm. Every time I would dig into a wall or rut it would yank my tires all the way right or left and I was powerless to stop it. Moved the draglink out a couple inches on the arm and problem solved.

If you put it in that close you will lose a lot of leverage and will either not be able to turn your tires on the trail or will Pretzel your drag link or strip you steering box out.

If you need more turning radius, why not just use a longer pitman arm? Only reason I see not to, would be if a longer pitman arm causes the links to bind during articulation. Even if they do bind, you could always relocate the steering box. Just my .02.

I used a '79 F-150 pitman w/ 4" drop made by I believe skyjacker. It was about an 1" longer. I did this because I used '79 F-150 knuckles (on a '72 EB dana 44) and they were a little longer. I needed to get my turn radius back. The pitman was a direct bolt-on to the '98 TJ box. Daily Driver like this since '99 with absolutely no problems.

The stock (no drop) will not work.

I used a grand wagoner arm. No drop, and longer than stock.

But my steering is different than yours:


Here's detail on what the Grand Wagoneer arm looks like:

(don't mind the angle on the pitman TRE - it's been adjusted straighter )

I can't use a stock wagoneer pitman arm b/c it hits the sway bar. I still have sway bars b/c I also drive this on the road. the dropped wagoneer arm is to much of a drop b/c it hits the tie rod now.

I have tried both ways.

1tontj: I like your trac bar setup can you post more pics of that?

I was just showing you that this one is longer. Good for getting the steering radius back.

I did have to move the box a little though.
