I'm with davis3--probably a case of springs not seated properly.
Is the problem primarily in the front, or rear, or both?
If it's primarily front or rear that's different, jack up the tall side and let the suspension fully droop. You should be able to see the tail of the spring on the bottom, and see if it's fully seated in the pocket of the LCA. If it's not, depending on the amount of drop your car has, you might be able to move it without a spring compressor and a full removal.
If it's both, do you have some way of getting the car up, but with the weight still on the tires? That way you could measure the compressed spring height on each side and compare, to try to further troubleshoot.
Got pictures?
