Passenger side suspension woes

2008 r350

tye passenger side started drooping

i ran the vin, air suspension in the back, but not the front. Since the drivers side is upright (strong like bull) I conclude it can’t be the compressor, because in my head they would both be down.

what would cause just one side to droop?

what should I check first?

thanks all, this site has helped a lot

the pics are the good side vs bad.

Air valve under the right headlight.
Get at it through the right inner fender (after taking the right tire off).

The inner fender is in 2 sections divided over the axle. You might as well remove both and have a good look around.
You be able to see how the heater line is routed, and the air filter for the air compressor.
The hose supplying the filtered air likely has pulled off the compressor end, but maybe not...

That hose is thin, one end is different inside diameter than the other. Is an oddball.
It is possible to shorten/remove the couple inches or so that loosened off the compressor. But there's not a lot to play with.
