Condition

Some customers may comment on the rear suspension being uneven or sagging.

Correction

DO NOT REPLACE THE COMPRESSOR.

Based on technician feedback, engineering has determined that the customer's concern can be corrected by recalibrating the air spring sensor. Refer to the Trim Height Uneven or Low diagnostics and Air Spring Sensor Calibration procedure found in SI.

If your door sags it means the bushings in the door hinge are worn out, but there is a way to adjust it without replacing the hinges if they aren't too bad. If you open your door there are bolts that attach the door hinges to the A-Pillar, most of the time they are accessable from the outside. First get a car jack and position it under middle edge of the open door, put a small piece of wood on the jacking point to protect the door. Loosen the bolts to the hinges and raise the jack so it raises the door up. tighten the bolts on the hinges back up and open and close the door to determine if the door was raised enough to eliminate the sagging.

If the door is not latching properly, a torx drive bit will fit into the latch pin itself and you can move it a little further outward. If the door is sagging (don't quote me on this, i'm not real familiar with the model), you may be able to loosen the hinges and lift the door, you may have to replace the hinge pins, or the hinge altogether.

I believe your hinge pins are worn. The only fix is to replace the hinges or the hinge pins. Neither is a pretty job.

3m makes a great spray adhe they sell it at walmart for $10 in the auto section , most of the time do it right in the car remove any side trim and spray between liner and board and smooth down.

put a car floor jack under the door and jack it up loosen the screws and try to close the door, you might need shims or washers. tighten each screw top bottom each one til its down so door must be leviled on the jack then bolt it on one at a time

you could try some door shims in the hinges
