cj-7 overall spring width narrower in rear than front of front axle

thanks I do have another issue, when I mounted the springs to the axle, I had a 1" difference in width front of spring to rear of spring,
IOW's
the rear of the front leaf measures 29 1/16" outside of spring to utside of spring at the rear hanger, the front (after setting the axle down onto the locating pins), at the hanger measures 30" and forces the shackle out at the bottom creating the shackles to point at an angle, it is like the axle dowels are to wide by a half inch or so, my jeep seemed untouched before except for new red poly leaf spring bushings,

so I checked the rear as well and get the same thing, only in reverse, the front of the rear spring is 37 11/16 overall width at the hanger and the rear of the rear springs is 39 11/16 overall width, I'm measuring spring to spring not the bushings, would it be that the bushings should be smaller on one side? of the spring? IOWS one half of the bushing be a 1/4 skinnier than the other half?

Any help would be appreciated!

That usually means you connected the springs in this order:
1) at the frame
2) on the axle
3) at the shackle

If you connect them in this order, you can algin the spring on the perches more accurately.
1) at the frame
2) at the shackle
3) on the axle

I connected to fixed frame mount bolts snug not torqued, then shackles, again bolts snug not torqued, then to put set the axle on the pins, I had to spread the sprig slightly,I let it hang before trying to tighten anything, it then coks the shackles outward a the bottom, so I started measuring to find them about 1" wider at the front cocking the shackle

thanks for the help!

Mine measure 30" outside to outside on both ends of the front and 38-3/8" on both ends of the back.

Could it be your axles shifted relative to the frame, when you had it apart?

I've found it easiest to attach both ends of the spring loosely, then wrestle the spring perch and centering pin together. Sometimes, compressing the spring with a floor jack, placed to one side or the other of the spring plate, helps as well.

it would ten be off to one side, the springs are actually closer together in the rear of the spring (fixed frame hanger) than they are in the front (shackle end) by 1" I took a pic of each, you can see right side angled towards right outer of cj, and the left angled out to the left side of cj, I had originally thought I had a bent shackle, but they did it with new shackles as well

Since you like to measure things (grin), have you checked your frame dimensions? It could be your frame is tweaked, slightly, causing the problem.

Here's the blueprint.

I'll need a new tape before this is over <g>

I have actually tried to find the width spec for the spring mounts with no luck, thanks for that drawing, I will try to see if I can tell if the fixed mounts are off on it now

As shown in that drawing, the hangers and shackle mounts for the front axle should be 27.5" apart (center to center) and the rears should be 36". The mounting points should be the same width apart as the center to center measurement of the spring perches of their respective axles (maybe something else to check, perhaps the perch locations are slightly off).
