2008 GX470 W/KDSS & Eibach Pro-Tr. Stage 1 @ full ht. (1.75” front & Dob UCA’s) with Airbag Man ext. air bags. All good but auto leveling not working.

So I have a 2008 GX 470 sport edition and I installed the Eibach pro truck stage one lift system in the front set it @ 1.75 the highest and have airbag man extended airbags on the rear. I also put Dr. KSS swaybar adapters on as well as a diff drop. The air bags were installed with the spacers double stacked as per the instructions. When I brought the vehicle home it was super high in the rear so I removed the spacers and that dropped the back end down to something more acceptable so I feel like the sensors are working. In fact, I’ve had it checked, and everything appears to be working, except the auto leveling function. I don’t have tech stream yet, but in the meantime, I was wondering if anybody has gone through something like this before and how was it fixed? Thank you.

Were the air bags installed with spacers or were the leveling sensors installed with spacers? If the former, your sensors think you're at stock height and won't auto level.
If you want the diff drop, its your money and your rig. However, I'd advise uninstalling it. Here are a couple of videos why:

There are separate sensor left and right. They need to be adjusted to read within the tolerance or it would just confuse the system. A higher end scanner should be able to see the values sent from the sensor.
