I recently finished doing an axle swap. I went from a Super 35, to a Ford 8.8. In the process, I went from a Detroit in the rear to an ARB. After installing the axle and Compressor, I proceeded to do the leak-down test. Sitting in the driveway it will hold pressure for at least 30 mins. (Probably longer but I didn't want to wait for it to turn on.)
My problem is when I am out wheeling, it will hold pressure fine until I get on an incline. Once on an incline, it pumps about every 3 seconds until I return to level ground. Once I get to level ground it holds pressure fine.
Any ideas what is going on?
