GTX not level..help

[optiview]

I have a 69 GTX with new everything. The rear left side of the car was about .75 in lower than the front. So I was told oh.. its the rear leaf springs. So I had them replaced at the shop and the aligned car exc. Well now it is still .75 in lower in back and after measuring front I found it to be about .5 in higher on left side! What is going on? Any suggestions would be helpful.
They want to shim the back springs but almost an inch off? Must be another explanation.

Did you try adjusting the torsion bars? Are you running superstock springs?

 

[optiview]

yes mechanic adjusted torsion bars and I am using stock mopar performance springs.

could be two things

1. the torsion bars still need to be adjusted

2. the front springs perches are installed wrong

ill check that thanks

not to be a smart-***, but is the ground level where you are measuring?

I had the same dilemma with my GTX. However, it had been hit hard in the front corner, bending the frame rail and then it was bent back, but never correct. I ended up trashing the entire front clip not just because of this hit, but because of the cumulative rust and rot!

Just on a hunch, try loosening all your spring bushings, both sides, front and rear, drive it around the block, then come back and measure it again. If it's correct, torque em down. If not, try jacking the low side up, just beyond where it would be sitting level, then torque em down. That just might cure your problem.

I agree with one, but #2 is not probable unless someone went out of there way to do so, as you have to elongate a couple of the holes in order to flip the hanger, and then the nut side is on the wrong side unless the hangers were also swapped side to side.

If a torsion bar adjustment is not the easy solution, I recommend you take your car to a frame shop to see if the frame is straight (probably not).

These cars were never perfect to start with, and throw in a few decades of thrashing, and maybe a crash or two, and the frames (uni-bodies) get twisted enough that they can cause problems that just can't be adjusted out, without straightening on a frame jig (fairly simple procedure).

Check it out before throwing parts at it.

#2 I have seen alot on Mopars that have been raced

I agree with G-Ship -its a GTX so that means it came with a slant 6 or a 318? No, no that means it came with something a lot bigger. Big power in a unibody means its probably be romped on and twisted a bit. we all have this problem! I would not let them shim anything. Just run it loud and proud!
