I want to machine my own high steer arms to be used on a jeep Wrangler with a D44 front. I am going to use the old steering arm to get the knuckle bolt pattern but I don't know what the locations should be for the tie rod and drag link holes. Would any one happen to know what the locations would be, how far from the front knuckle bolt hole and how far to the side of the same bolt. Any help would be appreciated. <IMG SRC="smilies/roxy.gif" border="0">

Depends on pitman arm length, but drag-link TRE 6" from ball joint is pretty common. Put the tie-rod TRE's as close to the tire as you're comfortable with to get at least a little ackerman angle.

I am not sure of the P-Arm length but it is a drop P-Arm for a 4" Skyjacker suspension lift.

Thanks for the info!! <IMG SRC="smilies/roxy.gif" border="0"> I'm rollin' now.

On a related note, what are the effects of putting the tie rod holes closer or further from the ball joint (more or less than the 6" I have right now?).

you wont need the drop pitman arm.. for the hole location.. mine are about 1/2" inboard than the stock tie rod hole.. (towards the center of the jeep).. and also about an 1/2" towards the rear...
this 1/2" to the rear caused my wagoneer pitman arm to hit my tie rod.. ugh.. its not bad.. but it binds alittle with some flex upwards.. currently looking for a shorter pitman arm..
i have a good write up on my web page..
and unless you actually machine these yourself.. they are cheaper to buy.. unless you know someone that knows someone.. <IMG SRC="smilies/glasses.gif" border="0">

Jeepgod, move the box forward. Don't shorten the pitman arm or you'll lose some steering travel unless you shorten the knuckle arms too.

It determines how far the tire turns for a given amount of drag-link movement. In other words, it affects the steering ratio, but it also affects the maximum turning angle. Move the TRE closer to the ball joint and the steering response quickens and the tire turns farther (greater angle). Move it away from the ball joint and you get slower steering and decreased turning angle. Exact opposite thing happens at the pitman arm (because input / output path is reversed). Longer pitman arm = quicker steering / greater maximum tire angle. Short pitman = slower steering / decreased maximum tire angle.

Edit: Correction, I was assuming the drag-link was connected to the tie-rod TRE. If the drag-link TRE is mounted separately to the steering arm then the above applies for the drag-link TRE, not the tie-rod TRE's.

Is this true if we're talking about keeping the draglink in a separate hole (let's say 6" from ball joint) and moving the tie rod mounting holes inwards? So the ratio of pitman arm length to steering arm length (at the draglink attachment hole) is kept stock, but the tie rod is moved closer for more tierod/draglink clearance?

Oops, I was talking about the setup where the drag-link connects to the passenger side tie-rod TRE (85' Blazer TRE's). My mistake for not clarifying that. <IMG SRC="smilies/emb.gif" border="0"> I guess I should have left my original post alone (drag-link at 6" from ball-joint). I'll change the wording for that post, thanks for pointing that out. Moving the tie-rod TRE's closer to the ball joint is fine, but it does increase the load on the TRE's. Make sure you have the clearance to move them closer.
