1990 Mercedes-Benz 300CE Question: Rattling

 

Question

Visitor, Redwood City, CA, May 28, 2011, 20:45

The rattling noise occurs while driving, all bumps and manhole covers. Sounds like the middle of the car. Sounds like a heat shield or thin tin sound. When its up on a hoist I cannot make the noise happen. Not exhaust or catylyst.

    The lift that your car has been checked on. were the wheels suspended or was it a drive on lift were the car would be as it would be ride height wise as it would be on the road? It sounds like it's a heat shield problem but it would be best to check the car at road ride height suspension "loaded".

    You can always drive two wheels onto a curb and crawl underneath...

    Good morning. From your description it does sound like a heat shield. If you can please stop by I will be glad to go on a test drive to determine what it is. There will be no charge for the check out.
    Thanks, Mike Young, Service Manager.
