Car Is Uneven

[badazta]

I have a 79 Trans am. I just replaced the air shocks and old stock suspension with new hotchkis springs and kyb gas-a-justs. The car sat uneven with the rear driver side 1.5 inches lower than the passanger side before the swap and i thought it was due to sagging. After the swap the passenger side is still 1 inch higher. The front of the car sits pretty much level. The car tracks straight and I feel no drivability issues with it. Any ideas of what is causing this? Also if I put a 1 inch lowering block on the passenger spring to level it out will that mess up anything? Thanks for the help

Have you looked at the body bushings? Is the car straight?

I second looking at the body bushings. I would also loosen all the bolts on the leaf eyes then put it on the ground and push the car up and down to work the suspension a bit then retighten them with the full weight of the car on the suspension.
Id also do it with the A arms.

I would not put a drop block on only 1 side it could throw off something geometry wise. You have another issue somewhere and why bandaid it.

Find a good slab of flat concrete and measure from top of wheel opening to the ground and compare side to side.
If you find a twist in the body you may have to split the difference and shorten one coil a little as the front springs have more influence than the rear.
If the body has a 1.5" twist for example, then cut a 1/2"or so off the drivers side front spring.(That being your high side)

I had this experience with a 68 Ford falcon G.T. It had never been in a smash. Must not have been sitting properly on the assembly line when they welded the body together.

Body bushings, or where they mount could be rotted/rusted out would be a good start. I just resolved the same issue with my problem being the rear swaybar being either misdrilled or the mounting ends were not coplanar, or parallel. My passenger side leaned about 5/8" lower that the driver side. I would have never guessed that a sway bay, correctly drilled or not could have that much effect of body lean. Rear bar was a 1 3/8" dia solid bar. Also, one of the front sway bar links being tightened down too much can also cause body lean, at least on turbo bricks. HTH
I would cut the springs as a last ditch effort. I would also consider putting a thicker spring isolator on the leaning side long before cutting springs. Also, did you clock the springs correctly so they sit down in their seat properly? Might want to consider having the frame checked for straightness/twist on a frame straightening machine. I have a hard time with cutting 1 spring because you can't isolate the problem.

Thanks for all the suggestions. The problem is only in the rear, the front sits almost dead level when measuring from the top of the wheel opening to the ground. I did just put on my new wheels and while I was at it I checked the sway bar, I noticed that the driver side brace (or whatever its called sorry if I sound stupid) is slightly bent. I don't know how I missed it before. I'll try replacing both of them and see if it works. Thanks again
