Has anybody experienced rattles with their sunvisor? Whenever I go over a bump, and it can be as small as a sewer cover, I notice this rattle coming from both my sunvisors. I'm pretty sure it isn't the dreaded windshield crackle that many here have complained about because when I move my visor to different positions, it lessens the noise. I tried greasing the part where it connects to the roof of the car with no luck.

Help anyone?
