Tight screws=quiet cab
We've been driving our '05 Dolphin and the noise level in the cab has been getting worse over time with some really irritating squeaks and rattles. Listening to audio while driving was getting harder. I thought it was a fact of life of a coach getting older and showing its age.
Before this trip, I did a major glass cleaning job. While sitting on the dash and washing the inside of the windshield, I noticed a couple of screws sticking out of the windshield pillar trim strip. So I got a screwdriver and proceeded to tighten them. Then I started going around the entire perimeter of the pillars, dash, and overhead panel. Almost every screw was loose! I tightened them all up. We noticed the difference right away on the first drive. Lots quieter and the major noise was gone.
Maybe I am slow, but you might want to check all your trim screws to see if any are loose. I can hear the radio now.
