After a day or two while parked. My boom truck rear outrigger creeps down a few inches. Only the one does it. Any idea what would let that happen?? Thank you
Well if you don't see a leak on the cylinder or hoses, fittings, valve etc. Chances are good you have a leak past the piston seals in the cylinder. But not having ESP and not knowing your boom that is as far as I can go. You can support the outrigger, pull off the lines at the cylinder, cap the cylinder fittings, remove the block and wait.
