I'm new to the site. I've been working on my first jeep (56 cj5) for several years. I've done numerous muscle cars, trucks and car flips. I finally got the CJ on the road this fall, only to (occasionally) be experiencing a violent bouncing of the rear. So bad, i need to pull over, coast to a stop. I can get right rolling smooth again right after, like nothing happened, until it will occur again. I have done an SOA, with longer Cherokee springs in the rear, stock CJ, 7 leaf,up front. stock axles. I had pulled two leaves out of the rear springs, was running fine. Then one day, I hit a series if bumps in the road when i first noticed the bouncing. Thinking axle wrap may be the culprit (but i have never experienced it in an y other vehicle before) I added one of the leaves back, but now it occurs more frequent. I know there can be many issues with the SOA, I've tried to address all, but fear I missed something. Reading thru many posts on the subject, pros and cons on SOA, I'm seeking advise direction. I did a lot or research and took my time, but obviously missed/overlook something. Any help advise would be greatly appreciated Is this an axle wrap, wheel hop issue? Will a ladder bar help to eliminate? Are these other areas I should be considering. I've never experienced this issue before on any of my other cars or trucks. I appreciate any and all advice one can offer. I love to put the wrench time into my projects, i just want to be certain as i can that I take the right course of action.
