Does any one have the frame alignment specs for the 2 door JK?? or maybe someone could measure thier stock 2 door wheel base for me PLEASE!!!!

I installed my FT 3" Ultimate lift last week and my wheel base a 3/8" longer on the passenger side.?!?!?! I triple checked the length of all the control arms too!

I forgot to take before measurements of the wheel base on both sides before installing the lift. Now I do not know if the passenger side wheel base needs to be shorter, or if the drivers side needs lengthend!!!


HELP!!!!!!!

 

Both. You want to center your axles under the frame. The front and rear track bars will cause the axles to move in opposite directions. You need to adjust your front track bar, if you have an adjustable track bar, to center the axles.

I do not think anyone is understanding my question.

OK my axles ARE perfectly centerd side to side with the track bars.

My wheel base is off FRONT TO REAR. This is measured from the center line of the front axle to the center line of the rear axle on both the passenger side and the drivers side.

.......... and after talking with several people and service managers I just need to measure the wheelbase on a few stock 2 door JK's and go from there...................unless some one has some specs!!

 

There is manufacturing tolerances that come with any vehicle. Choose a road that you can be driven on the same side in both directions, this eliminates the road conditions. While driving your Jeep does it pull in one direction?
How are you measuring the wheel base? An alignment shop or Stanley? I am guessing tape measure since an alignment shop would tell you if your thrust angle or set back is off. Set back refers to the front axle and thrust angle is for the rear axle. Google is you friend. The only accurate way is an alignment shop. Its possible that both are slightly off. TeraFlex recommends that the front right lca be an additional turn longer to eliminate the JK's tendency to pull to the right.

 

The absolute best source for this info would be a good, reputable body repair shop. You might even consider taking the Jeep in and letting them align it for you. This would be a "one time only deal" and probably yield you the best results you could hope for. This probably isn't the answer you are looking for but it sure would be the route I'd personally take. Good luck... Mike

 

You should read Rubar's link there. It should answer your question. I have read some kits do this to compensate for the JK's natural tendency to pull right.
If you don't like it, just align it yourself. You don't need to worry about the stock specs if you are no longer stock.. aka, lifted.

IMO ... I don't answer alot but I do read alot. So take it for what its worth to you.

 

I find this interesting as my JK has a bit of pull to the right. I've been correcting for it by having the right front tire run 2 psi more air pressure for a bit less rolling resistence. Does it actually correct this tendency if the right arm is one turn longer? If so it argues for a kit with both upper and lower arms adjustable.

 

is this what you are looking for? I think this is for a 4 doe but I can get you 2 door on Monday if it is.

Yes, it does correct the pull. What argument are you talking about?
