Gimbal bearing or u joint?
I recently noticed a growling sound when running. Worse at speeds above 40 mph. Changes, but doesn't go away when wheel is turned, or when trim is adjusted. I have twin engine setup 2004 bravo xr's with Stellings extension boxes. Drives where gone through 2 running hrs ago. Pretty sure it is gimbal bearing or u joint. Is there a simple way to diagnose the problem, or to distinguish port from starboard? Can this be easily diagnosed without running the boat? Boat is in lift so I will need to run it to the launch to get it to the shop. Thanks!

Pull your drain plugs on your drives and look for metal first. You may have a gear going south.
