Hey Guys,

The past couple weeks my car has been making a strange rattling sound (thats the best I can describe it). I could have sworn it was the heat sheild for the exhaust, but I brought it to a local shop real quick and it all checked out.

It sounds like marbels in a tin can or sheet metal rattling. My initial thought was IMS BEARING, however, it comes from the front area of the car... the engine purrs, no ill sounds at all... so it has to be the heat shield, right? It only is noticable when in low gears and accelerating. It is quiet in 4th and 5th gear and on the freeway.

Maybe I should bring it for a second opinion....

Any thoughts?
