This is pretty common. As you put more miles on the car the SC coupler wears causing the marble rattling noise at idle. Only way to fix it is to replace the coupler but it is normal.

I hear a noise when I drive sometimes but I have no clue what it is and where it's from it happens after I rev just at the time the rev is going down. sounds like a fan tapping something....but not hard is more of a soft sounds. u know sorta like the sound a cat makes.....
