Probably the fastest, easiest method would be to do the coil spring conversion. At $339. It would be all over.
If you wanted to keep the air, I would focus on the solenoid and air supply line on the RR. As the rear ionly has 1 sensor and is designed to raise both sides evenly. If they aren't, theres either a leak in the air spring itself or leaking at the air line going to the solenoid.
If the air springs were rebuilt, that is probably going to be the problem. As they generally last only 2 years.
