Also, make sure you don't leave any bits of gravel between the shield and cat because that what I forgot to do......

I've tried to listen for exactly where it is, but it is not easily located. I'm hoping that someone may have experienced the same thing. The best I can describe the noise is as it sounds like something is loose and rattling and coming from the front left right behind the steering column. It never is there when I am in park, or when I am driving. Its fairly loud and can easily be heard in the cab. If I turn my steering wheel enough, the rattle stops but it seems more to be the changing of the idle that does it. If I put the truck in park, it immediately goes away. When I accelerate, the noise goes away. I'd say the noise is there about 50-75% of the time when I am in drive, but stopped. Mostly I notice it at stop lights, etc. Any help on this would be greatly appreciated. I took it to the mechanic twice and both times they said they could not get it to replicate, so I'm going to attempt to fix it myself if possible. I replaced the coils and plugs about 10K miles ago, oil changes are kept up, and have a new battery and alternator (I don't believe these have anything to do with it but just wanted to note) Any quick/easy fixes I'm more than happy to attempt and eliminate first if anyone has any ideas. Thanks!
