Tie rod flip and stretch Pitman arm interference

This is kind of an Unorthodox axle swap so bare with me. I recently swapped in a 8.8 with 4.56 gears and Detriot Locker this is where the unorthodox part comes in. I have been saving for 4.56 gears for my HP dana 30 but I ran across an add in craigslist for a dana30/35 combo with 4.56 gears for $100. I called imediately and come to find out the 30 is a LP out of ZJ ugh!! Im a budget so I bought them. A few minutes later and a sawzall and cutoff wheel. I figured I can sell the rear 35 to recoup some costs.


I Made my own spring perches to gain an inch more lift over the stock dana 30 spring perches.

the LP dana 30 came with a tie rod flip so I figured I would make use of that since my spring perches gave me an inch more lift in the front I cant run my tie rod with it under the knuckle ( to close to the springs now with my new SUA perches ). Im also running waggy springs giving me a 2" stretch. With the tie rod flip I am having interference with drag link contacting the tie rod. I will let the Pictures do the talking. I have a stock pitman arm. I only have 1" of uptravel before they contact each other.

Can I also flip my drag link up to the top of the pitman arm too? giving me enough clearance between the arm and tie rod. I know I will have ream it out to fit but will it interfere with anything else?? Will I have to lengthen the drag link?? If so I can do that. will it bind?? can I run a flat pitman arm will a waggy arm work?? I dont want to lose my sway bar with a flat arm but if its the only way to make it work then I can remove it. Obviously the biggest factor here is my waggy springs with the stretch. Well Im off to do a bunch more research but I figured I can ask the questions here and see if I can get some feedback.

Looks like you have a steering issue. I read somewhere that the Durango pitman arms are a lot shorter than the Yj arms. Perhaps you can try to find a shorter arm somewhere.

Don't quote me on the Durango model!

I have the same problem with the stock setup and I even made a thread about it.

http://www.jeepforum.com/forum/f12/d...rance-1237438/

There's some good info in it. One thing that was suggested was a bracket that moves the steering box forward 1".

I know I've seen others who have bought custom pitman arms so I'm sure that's an option.

Chevy astro vans have a pitman arm that is completely flat, I have seen people use them on their yj with high steer bracket. Duno if this would help solve the issue or not but it would get the drag link up a few inches higher.

Thanks guys these are all really good ideas. I have thought about using an astro van box to but I don't Think a 2 inch stretch constitutes that, but being so low I may go that route. Louie I have been following your thread since you bent your steering to see what route you go to fix it. I really like the tie rod flip, it gets that tie rod so far our of harms way. I just don't have enough lift to clear. I will read through your thread Louie and get more ideas. Thanks

Right now I got a bead on a Teraflex cross-over steering knuckle with 1.5" O.D. tie rod, and I'm unsure about the size of the drag link. It also has 1 ton TRE's.

The deal I'm getting is awesome so I can't pass it up. Being that I have a small lift I will need to figure something out. The Teraflex knuckle has a top mount for "hi-steer" where the drag link goes. However I think there will be interference with the pitman arm. I have a stock and a dropped one. If there is not much room I may look at flipping the stock pitman arm and reaming it. I have no idea if that will work but it's an idea. I will update my threads once I get the parts in the mail.

Yeah my idea is to ream the stock pitman arm on top and run my drag link on top of the arm. I'm just not sure of it will bind??

I believe the Ford Ranger has a pitman arm that is about 1" shorter than the stock YJ arm.
Is that a 4" drop pitman arm you are using?

Erik,

I've done some research for steering systems and I have come across some of your threads but the pics are no longer there. Anyway you can shoot me some pics and a small description of your setup?

Mine is all different now, but it was once a crossover style steering similar to yours.
I did use the Ranger pitman arm. You'll have to file out the keyway to get it to line up properly.

Thanks for the pics. What was the reasoning for the Ranger pitman arm? To bring it back close to stock specs?

It is about an inch shorter than the YJ pitman arm, and prevents crashing into the tie rod at heavy articulation.

Thanks for the info. I think I'll be scavenging the pull-a-part for one once I get my new steering setup.

I believe its a stock arm?? I haven't compared it to any other arm to see for sure though. I will look into the ranger arm. Thanks. Does the ranger arm drop any? What year ranger?? I will be hitting up a J yard soon
