spring over on my YJ is almost undriveable!!

[spencurai]

I did a spring over on the rear of my YJ....I had lift springs on it before but they were wrapping and giving me some problems...

So I bought some springs off Shawn and removed the add a leafs as they netted me about 8 inches of lift over what I had...or so it seemed....

the leafs are flat as a board with the vehicle weight on em but the axle wrap makes it almost undriveable...I know it is time for a traction bar because that is what I originally intended to do in conjunction with the spring over.

has anyone else has this soft of spring...I think they are ranchos as the add a leaf was a rancho full length.

Huh. I haven't heard of one being undriveable on the street due to spring wrap. What'd you do? We used JC Whitney 1" lift springs on my dad's YJ, and they are pretty soft and flat. It drove great on the road, and even towed a popup trailer fine. I did build a traction bar for it before he took it off road, but it worked fine on the street. Just build a traction bar. They're easy, and it'll solve your problem, if your problem is really spring wrap.

You've always needed a traction bar, you were just too lazy to build one!!

well I have 4.56s with really shouldn't enflame the problem but I cant hop on it or I get some driveline bind in with the CV rear..it is set up perfect with the angles on the drivline primo so....I dont know...was your dads an automatic?

No, five speed and 4.10s. 1310 drivelines. Maybe your driveshaft angle is too severe for your CV? They typically don't provide as much operating angle as a standard ujoint.

My CJ, sprung over with with YJ's and a leaf removed was damn near undrivable without my traction bar. It was scary how hard those springs would wrap under heavy accel.

seriously....the pinion points towards the sky and binds up the U-joint on the pinion end....I put my brother in it and had him do some hard take offs while I looked underneath from the side...it was scarry!!

I know it is in need of a traction bar...which I have welded on another project but it just seems odd to have that much wrap....it really freaks me out!!

I have never heard of a SOA conversion that did not need a traction bar. YJ Springs are very soft, that is why they are sought after.

When I get home I will post a pic of my "pre traction bar" carnage.....nasty. Blew up a rear yoke due to axle wrap.

the springs I am running are great though....wicked soft and with the vehicle weight on them, FLAT AS A BOARD which as we all know means wicked flex and a great ride!! gonna do the front in the spring most likely.

They'll be negative arched & loosing lift soon enough... thats' what YJ springs do. I personally think you need a somewhat firmer spring with a little arch, for a YJ SOA. Also, you might want to bumpstop the uptravel so they don't go too far into negative arch, as that will kill the springs faster that anything. Traction bars are not an option either, they're a MUST.

4000+ posts and you didn't know you MUST HAVE a traction bar with yj spring's sprung over? Hum....

Well you should just build yourself a wicked cool traction bar, for your wicked cool Yj springs, and then get some wicked flex!!

See you on Hell's Revenge...


Oh no I wont, I forgot I dont have a Jeep. :sick:

THAT IS FUNNAY

Sounds like you have two problems. 1) Springs too soft. 2) Driveline angles incorrect. Generally a CV at the pinion end should be a degree or two lower at rest so when you give it gas it rises and the angle is zero. How many leaves are in you spring packs? It is very typical to ADD 1 and even 2 leaves per pack. I have cautioned people before about using Wrangler springs, they are simply too soft! Consider they are designed for a jeep with very little wheel travel and weenie tires. And they are flat in stock configuration on most Wranglers. Add two leaves per side and seewaht that does for you. It is a lot easier and cheaper than building a traction bar, although that is certainly a good idea too.

The driveline angles are perfect...that is not an issue. The springs might be soft but they are not OEM so they should be alright for my needs...

did you guys skip the reading comprehension portion of your public education....re-read my first post about my original intentions for a traction bar...HELLO....??? DIDJA MISDAT?? do I need to write it in ebonics or something.

This whole post is about the interim between the installation of the spring over and the traction bar....I swear you guys need to put down the beers while surfing the internet

Flat springs and oversized tires do not go togather. The larger the tire the worse the wrap. Just because you are using stock springs does not mean that you are exempt from axle wrap; besides a SOA is completely and totally different than a SUA.

I realize you were asking about a traction bar. But you need to address the root problem first! I ran stock CJ springs for years without any real noticable axle wrap. I only have a traction bar now because Carl talked me into it. Trust me; add some leaves first.

OOPs, missed that little tidbit. If they are aftermarket and they are flat when weighted, then they are probly worn out!!
