2004 S80 Front End Rattle/Buzz

[wjkmd]

I have a 2004 S80 that has a passenger side front-end rattle/buzz when going over bumps/rough roads---but recently I hear it more often. It goes away in rainy weather. Could it be a sway bar link or bushing? Of note, the dealer had the passenger door panel off several times to fix the door actuator, but the dealer says no buzz is coming from door components. Any ideas? Thanks
