I noticed while driving with my window down today that there is a slight rattling sound when the car is moving. It stops when i come to a complete stop. Any ideas what it could be?

 

Does it come from the front or the rear?

If you have a froozen caliper or guide pins, you might have loose brake pads rattling around. The rear is very prone to this.

 

It's coming from the front.

 

rattling like something is inside the wheel ... or a ticking as the wheel turns ... or a popping sound when you turn the wheel/hit bumps or what?

 

if it's rattleing from the front tires, I had this problem and could only notice it with the windows down.. Like a metal on metal tapping sound.. Come to find out it was the clips that hold the wheel center stud on. It also had a washer type thing that the was hitting the clip causing the sound. I though it was a brake clip or something from the sound like a rattle.. But check to see if it is loose.. I know is hard to explain, but if you take your wheel off it would be on the center cap area o on the "car"..

 

i also only noticed when I was driving around high curbs or walls, center dividers that would reflect this metal sound back to the window.. What kind of rattle does it sound like, metal on metal?

 

it sounds like chain links rattling. It occurs when the car is moving. It doesn't have anything to do with steering. The rattling gets faster as the car gets faster. i will check the center caps tommorow.

 

yeah thats how mine sounded.. Like chains or something rattling inside the rim on the wheel stud.. My problem was the loose clips, hit them with a screwdriver/hammer to bend it in place... now it's quiet..
