I would check the ride height front to back and side to side that will tell you if there is something wrong with the chassis suspension. Just measure the distance from the top of the rubber bumper to the frame. Make sure the ground is perfectly level like in a Walmart parking lot your driveway may be pitched like mine to allow rain to run off. If your ride height looks good, then measure the bottom of the door panels front to back and side to side. This will tell you where your problem is. What were your 4 corner weights? Were they higher on the curb side? Let us know what you find and you will get better help.
