Do you guys meaure rear ride height when you suspect Airbags going out

[jsoto]

I dunno....
I'll have to look more closely at the rear ridge height (air springs in back).
For the last week, I've noticed the compressor kicking in almost every time I start the car. Compressors in the back , lid closed and all - and I can hear it working. I've eyeballed the rear height and it looks fine before I start the car.

Maybe it's a slow leak....on the bags.
