The back end of my '86 is sitting about an inch too low. At first I thought the level ride system was leaking, but the light never comes on while driving, only for a moment when starting the car. When there is weight on the back end, the level ride pumps it back up, but it still sits about an inch too low.
Is there a way to set the 'level' position?

Also I'm going to post some pictures of it after I wax it :bouncy:

There's a sensor with a leveling arm attached to the chassis, located above the rear end. I can't recall if it's adjustable, though. Best to take a look there, make sure the arm isn't bent, or the sensor isn't askew or something.

Another thing to check is the actual hydraulic part of the rear shocks. Unless they're good and holding oil, there's nothing for the air section to work against. Mine are shot and the back-end is sitting low at present despite the air working ok.

I'm planning to get new shocks all round next week.

If the back is low the springs are no good. But since you say the air suspension actually works and raises it if you put a load in it sounds like either its as high as its supposed to be or someone made it low porposely.

Here's a picture from the side, maybe it is at the correct height?

That looks pretty good to me. Usually when they are low, the fender lip is down covering the top of the hubcap...

Thats right where mine sits.

This is what it looked like when I blew the suspension
