I agree the circuit is sealed and generally those scroll compressors a pretty durable. I'd suspect "something" vibrating at the compressors frequency. Could be a panel cover, or even loose screw. If you're feeling adventurous pop the cover and check around. thump a few things with your thumb etc. Tighten or add a piece of tape if need be. Those units get jarred around bopping down the highway, grip the compressor like a football and jiggle it making sure it's seated on the pins correctly. The rubber isolators (on the feet) should be centered and not on a bind with the post retaining clips. Look on the inside of the cover or other surfaces for evidence of chafing or rubbing.
