I measured every corner of my max from wheel well down to the ground. The left rear measured 26 13/16", the right rear was 27 9/16". There was 3/4" difference in between. What's the culprit causing the uneven height?

 

You got a bunch of junk on one side of the trunk? Okay, actually it could be your springs are seated incorrectly on the perch on one side. Though if this is the case, you'd likely hear noises.

 

This car actually only carry me and some CDs every day. No noise come from suspension. I was so confused by this problem.

 

I had the same deal before I installed the Eibachs. I dont think it causes any problems.
