You just hit the mail on the head, “with 37’s”. I have the same lift, but with front and rear track bars, falcon 2.1 SS and 35’s all my previous wandering issues went away. Im willing to bet your entire wandering issues are related to the 37’s.
Just installed my JKS this morning. I've got skinny arms and feel sorry for anyone with large arms when swapping out the right side.
I won’t say it’s the “entire” issue but I’m not oblivious that it’s part of it. 37’s on 17” rims is a lot of sidewall and obviously more weight. There are some underlying issues though. What’s weird is the wander will change. Which I’m guessing is a steering box issue. This other stuff has to help, right?
The difference between 35s and 37s is not really that much. Get that track bar replaced and get your caster dialed in around 6 degrees. If you're still getting wandering you might consider changing out the tie rod and drag link. For reference I'm lifted 3.5" with 37s and I'm running the stock tie rod and drag link. I have 0 wandering. I do have the Rock Krawler track bar and Fox ATS steering stabilizer. Is your wander changing on different roads? Road condition/crown can have a major affect on handling.
Are you sure you're not tramlining?
thanks. Good advice. I agree road conditions will change some of the handling. I don’t count that. I will say that wind amplifies though. Or maybe makes it more noticeable.
I agree 100% change out your front track bar and depending on what your caster is set at get a set of adjustable LCA’s and go from there. I got about 3 1/2” out of my Mopar lift and it drives amazing. My caster is at 6 and I have front and rear track bars with the Falcon 2.1. What is your caster currently at?
It's actually the center of the bar that determines the roll-center height. Raising one end 2.5" only raises the roll-center 1.25". Changing the angle of the bar does have different tuning effects, but not something that is applicable to a Jeep.
great question. Just ordered a tool on amazon to measure my caster angle. Related question though, everyone changed out their lower control arms. When I talked to metalcloak, they said some had benefits from swapping out their upper control arms. Thoughts?
Thoughts are if your axles are centered and your caster is good no need to throw parts at a problem that doesn’t exist. Take it step by step and address the issues that come up. Get it on a rack and see where you stand before you throw parts at it. Everyone can give you opinions of different parts to throw at it, at the end of the day you may not need anything, never know till you get it on an alignment rack. I don’t know if I’m just lucky, but even at over 3” of lift my caster is perfect and she tracks straight as an arrow. Im a Snap on dealer so I had one of my customers at the dealer install my lift and he is a master of all things Jeep. His advice was exactly what I just gave you, wait and see. I’m glad I listened to him.
Thanks! and I couldn't agree more. Thats why I was starting with track bars. Not expensive and easy to swap. I know that the axles aren't centered so seemed like an easy place to start. Was going to go from there like you said. I also don't want to just throw money at it.
