Is my body tweeked or was it made like this?

This has been on my mind for a little while now.

Most other people don't (and probably wont) notice this about my GW, but I can see that it looks like it still sags a bit to the drivers side (in the rear). So I did some investigating.

On a level cement floor I measured from the floor to the Jeep's wheel well opening's. The drivers side sits lower than the passenger side by 1/4". Then, to see if it was spring sag vs body (mount) sag, I measured the height of the frame from the floor.

Here's what's odd, the frame sits higher on the driver's side by about 1/4". So, the problem isn't the spring sagging. Actually, that kind of makes some sense since the air shock on the left is at about double what the one on the right is (to compensate for the heavier load). So, where am I losing half an inch at? The driver's side (if things were perfect) should be up a little higher than the pass. until I let the air shock down some to even things out.

I checked body mounts next. None are sagging and the rear most ones I made are still good. After checking them, I took a crowbar and wedged it between the body and the frame and couldn't get it lifted any higher. Measuring the space (in the wheel well) between the body and the frame, both sides are the same. Looking at the Jeep from the back, both sides look pretty much the same and is straight with the bumper.

The only thing I can figure, is that either the body is tweeked (no signs of a previous major accident) or it was sloppily manufactured and the wheel well heights are off from the factory. Or maybe it could be tweeked from all the rust that it used to have... I don't know, BUT-which is it?

Has anyone else noticed such a thing about their full size jeep?
Thoughts/opinions/comment's?

Measure your Jeeps on a level surface, what do you come up with?

Mine's bent from a wreck. My data would be unreliable.

You found two spots within 1/4" anywhere on the jeep? That thing is a museum piece!

Go find another 30 year old vehicle and see if it measures perfectly straight and true and balanced all over. Especially a 4x4.

BTW....you didn't mention considering perfectly exactly matched tires all around. Even a tiny difference in tire wear, or even manufacturing, could amount to 1/4" difference in what you are describing.

absolutely zero chance of getting accurate measurements like that.
the difference could easily be floor used or your suspension/tire/spring/bushing/shock etc. etc.

Didn't you do a frame swap too?

Well, I better go measure my 93 year old Dodge car and the 32 year old Lincoln. Oh, and the 32 year old Dodge pick up too! Could measure the Suburban too, but its only goin on 26


Tires are perfectly matched, all manufactured at the same time (same date code on each one). I can and have switched them around, I get the same results. About 1/2" seems to be lost between the frame and body on the driver side.

Really? I've measured this in 2 different garages/shops with cement floors, one in several different spots and can't get that much of a different measurement.



I'm thinking my body is just fudged up. Either its tweeked from all the rust and the fact that it ran around for who knows how long without rear body mounts, or its manufactures defect. That I could believe too. I have read plenty about Jeep stamping machines being really worn out towards the end of production.

Yeah but my body is still slightly bent. My tailgate does hang correctly and my doors/front fenders are still a bit off but better.
