Leaf spring eye touches frame?

Any ideas as to why the eye of my leaf spring is touching the frame of my trailer?

Trailer is level and unloaded
All new equalizer, straps, and leaf springs.

I was trying to fix the problem by replacing all the suspension, but it is still there.

I'm super excited for someone to answer this. I have to pull my trailer way nose down to get the front eye of the rear spring off the frame. So, exact same problem.

Do you have a problem with the leaf spring touching the frame when you tow?

Are the frame side spring mounts equidistant from the center pivot mount?

(just spit-balling here)

My first answer would be that the center pivot mount got welded in the wrong place.

I think I figured out the problem. Any input would be appreciated. My spring perches on the front axle aren’t welded in place. So when I drove up onto the trailer they rotated and shifted the equalizer causing the rear to touch the frame

My understanding is the axle has to rotate to pivot the center equalizer, now it could have been it didn't get set up properly the first time and slipped...

I would on level ground loosen the front spring plate, rotate the equalizer to a neutral position and tighten things down on both sides. You could tack weld the spring plate to the axle to monitor movement but you could also see this at the equalizer.

Shackles look too long relative to the equalizer hanger bracket. Said another way: springs too long or shackles too long or hanger too short.

That shouldn’t cause your problems. I bet those are welded on the inside.

I just replaced the leaf spring and the perches definitely aren’t welded in place. I can get everything lined up perfect, but as soon as I drive away or load my Jeep the perches rotate and cause the equalizer to shift.

Shackles are too long, as someone else said.

They are 3 1/8” from hole center to center. Would 2 5/8” be a better fit then?

They make tall and short mounts for those suspensions.

The middle part can be a short welded thingy with a tall triangle, or a tall welded thingy and a short triangle. Looks like you got the short thingy and the short triangle.

Tall ones look like this:

In this picture, it sure looks like the springs have a 'clamp' on only ONE end of the leaf pack. That leads me to believe the springs are directional, and each spring pack should have the 'clamp' on the centered edge, and the 'loose' end on the outer edge. Try swapping the direction of the spring around, and see.

The clamps on the leaf springs should all be facing each other then? Pointed in towards the equalizer?

I welded the perches on, and there was no change. Back to square one.

The distances represented by the thin lines should be equal.

If you're asking for ideas, then that's what I'd try.

something isn't equal. doesn't look level in the first pic. one axle is way closer to the trailer frame. check your distance between all three fixed mounting points. should be equal front to back.

the clamps should all be facing forward so when the brakes are applied the clamp keeps the axle from wanting to roll forward
