There is a lot of relays, valves and lines under there. Your gonna have to build pressure up and get under there and hope it happens and find the leak.

You're going to have to search for the leak. There's literally a mile of air lines and a couple dozen valves in that truck. You're going to have to make the leak appear and then search for it.
Remember, air valves normally sit with the exhaust port open, so if you find a valve leaking air out the exhaust there's a good chance its something else backfeeding it.truckdriver31, Rideandrepair and spsauerland Thank this. -
