rear drop
 

my h2 drops in the rear suspension when parked--tested for line leaks- none i can find -is there a sensor that is screwing up or what is the problem

Did you spray the airbags themselves with soapy water? They do rot and will eventually leak all the time. ez replacement and not too expensive if its just the bags.

I second that, most likley the rear bags are the problem.

Im having the same problem. Did you ever find anything?
