Koni Yellow & Eibach Spring. Rear passenger side lower than others.

Both the front and the rear drivers side are identical and the rear passenger side is about 1/4 to 3/8 of an inch lower.

I have checked and both spring ends are seated in the nub like they are suppose to be and the tops are correctly seated in the rubber isolators. I torqued the control arm down after lowering it to ride height so I know it's not a "tightened in the air" issue either.

I also verified that both springs were identical lengths.

I didn't get to swap them side to side to see if the problem moved corners but I plan to tomorrow. LCA bushings is really all I could think of if the springs aren't at fault.
 
Air pressure is the same in both tires? Of course that would take a LOT of air for an issue.

And I think if the LCA bushings are shot, that could indeed be it. There is a how to on the old forum I think, but nobody ever took pics and made a real one.

But before you go that route, might be also worth making sure the shocks are also swapped over to ensure that is also not the problem.
 
For what it's worth, after jacking the back of the car off the ground and then lowering it back down, they both compress to the same ride height. But when I go drive around the block or bounce the bumper they settle differently.

Car only has 20k on it and I didn't notice a difference on stock suspension but again, the monster truck gap would have likely concealed it.
 
It's probably not perfectly flat. Just flat enough that the car doesn't move when you put it in neutral with the brake off.

The low corner ( rear passenger ) stays low even when backed in on the same exact spot or pulled long ways over the same exact spot. I would think that if it were uneven ground, it would change with the orientation of the car. And it stays the same when I park other places so there's that too.

Did not have time to swap them before work today but plan to tonight. If it moves to the other side can I safely say it is a spring defect? And if it doesn't can I safely say it's LCA bushings being shot?
 
I would take a caliper and measure the wheel to the fenderwell to see if the wheel is up higher before wasting any time.
 
I suggest measuring from the center of the wheel when measuring. And if you swap only do the spring. That's what determines ride height, and you don't want to create multiple variables.
 
Oh yeah, definitely.

The ONLY way to accurately measure this stuff is to do it from the wheel centers to the fender lips, perfectly vertically.

I had just assumed that's how it was being measured...
