: Steering Guru's I need opinions

I just replaced the factory cast bracket on my Commando with a
MORE steering bracket from the 76-86 CJ line. Well, once it was
in its final resting place the drag link was directly over the tie rod.
I have a HP 60 in the front with high steers on both sides. The
high steer arms holes are in the exact distance from the housing
as the factory knuckle holes. If I was to have the holes in the high steer arms retapered back on the arms will I lose alot of
leverage in the steering? I need either a two inch shorter power
streering arm or redrill the high steers. Or, I thought about going
with a slightly shorter arm and move the holes back an inch in the
high steers??

Shorter pitman, arm and move the tapers in closer to the kingpin or ball joint will basicly cancel each other out.
Shorter Pitman arm, essentialy reduces steering effort, but has less range.
Moving the tapers inward, essentialy, increase the steering load, but has greater range.
What are you trying to solve or achieve?

I think your best bet would be to just run the drag-link to a high steer arm, and drill the high steer arms farther back and mount the tie-rod there if you have the room to do that, without the tie-rod hitting the pumkin. Also if the tie-rod would hit the pumkin you could move the power steering box thingie (Highly Techinical term I use when I can't remember the right name) :flipoff2: Forward by about 2 inches. Both of those options leave you with the leaverage you have now.

Moving the steering box forward can improve your steering geometry(mine is moved forward about 3"), but it wont affect leverage, at the pitman arm.
The pitman arm recognizes its forces as related to the distance between the drag link connection and the center line of the sector shaft. The farther out the draglink TRE is from the sector shaft, the farther it will travel, but the more effort it takes to turn.
It will also be affected by the attachment at the steering arm. The farther out it is connected to the steering arm, the more leverage it has, and the easier it is to turn. But the result is less travel of the steering, due to the increased arch. By going in closer, to the ball joint pivot, the arch is shortened the steering is quickened, but the effort is increased.

Thanks guys, I decided to move the box forward about 2.25 inches to solve the problem.
