I will be painting my calipers next weekend, so will take a look at the brake clips and everything else under there. My Overland does it as well. Really doesnt bother me, but I do feel like its coming from the speaker.
It sounds very mechanical to me but I will take note whether the audio is on-off next time it happens.
Did you notice the frequency of occurrence getting more seldom?
I'd love to see how the calipers turn out.
I've only noticed in maybe 4 times since i got the vehicle a week ago. I swear I noticed is 2x in a row when switching from FM to XM radio. we'll see! I'm not too worried about it. Seems like something too obvious to not fix once dealers/chrysler get involved.
Just painting them black, but will post pics when done. have done it on my last 3 vehicles. Really cleans up the wheel.
