I started getting air leaks with the in cab contorller for my Rancho 9000 5 speed shocks. First it was the rear shocks. It turned out to be a bad O ring in the air bleed line. Next it was the front shocks. They would leak down to zero in about 30 minutes. I tried replacing the O ring but they still leaked. The soapy water test showed the air bleed valve is leaking. I talked to a service person who said they typically leak and as a result, he will not install them any more.
