chad, you have to jack the back up and try and rotate one of the springs, the way springs end, they just coil around and around and around and then suddenly end, but the way coils sit in the rear lower bag pockets, if you dont put them in the same exact way, what i mean is if you dont put them in so the end of the coil is exactly the same on both sides, one side of the car will sit lower than the other, you need to look at both coils, see where the end of the coil springs is inside the lower control arm, and make sure that both springs are the same. if you do this, or already did this, and one side is still lower, get some coil spring spacers from autozone, they start as thin as 1/2 inch, slip two of them in the lower of the two springs and you should be all set.
