    weird noises...what are they?!?!

    so whenever my car is heated up and in drive, reverse, 1, 2, or 3, it makes a really weird relatively loud rattling noise coming from the engine area. it sounds like it could be a belt but i have no idea...its a difficult noise to explain. it doesn't happen when the car is cool or when it is in park or neutral. i didn't notice it until i got my car back from the shop. i recently had a moderate tranny rebuild....automatic

    any thoughts?
    --------------------

    the other noise comes from the rear of the car. any time i drive over a bumpy road or a bump or anything it makes a rattling noise as if a few pieces of metal are clanking together. i don't know much about cars, but i went to the drivers side rear tire and kicked it and it made a similar noise. could it have something to do with the breaks? they are relatively new...only a few thousand miles on them.

    AHHH

    Its brakes, not breaks. COuple of things to check....RSM could be bad, anti-rattle clip on caliper loose, or maybe diff bolt issue.

    One odd thing I had that took me ages to track down was...
    The jack! It was loose and would make a REAL scary sound over bumps as it rattled. Some bits of foam is all it took to fix.

    Haven't experience that with my Bimmer yet, but when I had an Integra it turned out to be the heat shields on the exhaust. ???
