Dennis. All brand new. Thus shows about 30 miles driving. Already destroyed an earlier spring, a prior shackle and now this. Had Nates go thru it today and no luck, they are stumped too. Getting depressed so much time, labor parts and bloody knuckles on this rig and cannot drive it.

On the lift at full droop. P wheel 1” forward than D wheel causing the twisting but it’s all centered and all #s equal.

At full droop D side. Nice and vertical. Lower it down and both immediately lay over right. Any suspension experts?

the brand new OEM chevy joints were destroyed in mere miles. So added these orbital shackle hangers only on rear pax, rear top, one each side. It was doing the twist dance before adding the orbitals, thinking that would help, guess not.

That certainly could help. Also make sure the spacing of the front spring hangers, spring perches on the axle and shackle hangers is consistent. Orbital bushings don't resist sir to side swinging motion, like a typical rubber or poly bushing would, something elsewhere is letting the axle shift so de e to side. How good are the front spring bushings?

This was the first try with genuine new OEM chevy shackles. After 20 miles, twisted and bushing pushed aside with metal to metal contact.

That's odd if everything measures out. Center pin on the packs OK? Measurement from axle to front hanger same on both sides?

What does the other side look like? It certainly looks like the alignment of things is off, if the things are tight at the frame and at the axle, then the shackles (as the only part with movement built-in) will just move where the other two are pointing them.

Did you inspect your frame for any cracks? if the springs and hangers and bushings are good, then the frame is not.

frame was inspected and measured, all straight. no cracks either. research is 'leaning' (lol) toward a rear track bar to help center the axle. Have an artec truss to go in to support a center limit strap so maybe build off that...

Left front spring is AFU. DF is 1" higher than PF. hummm... Long ago plan was to go with YJ springs up front over the old skinny CJ pax. That is in the works soon too. This should be done anyway since the CJ pax are always breaking... Denis come over sometime and take a look if u like.

Some leafs have the hole drilled off center. Any chance one was flipped?

Are the spring pads C-C the same as the shackle mount c-c measurement?
