Question about 2002 Nissan Altima

A rattling from what sounds like the catalytic converter. It only happens as you slow down to a stop and then again when you accelerate from a stop. sounds like a part sliding back and forth on a bolt, but everything is tight?

Checked heat shield above it? Perhaps the inside of catalytic converter has broken up. Piece of the honeycomb like ceramics moving around. When it's cool, try hitting it with side of fist or rubber hammer slightly to see if you hear anything.

I would think the honeycomb ceramic "Brick" inside the Catalytic Converter has broken up, makes a terrible rattling when this happens.

Sounds like a rattle under the van when stopped or idleing


It is most likely an exhaust heat shield or a catalytic converter that is breaing apart inside. Get underthe van when it has cooled off and "thump" the exhaust with your fist to see if you can locate the rattle. Often, the heat shield welds break where they are attached to the catalytic converter. I have fixed many of them by taking 2 or 3 large screw-type hose clamps and screwing them together to make them long enough to reach all the way around the catalytic converter and tighten them down to stop the rattle. If the noise sounds like it is coming from INSIDE the converter, you will have to replace the catalyst. (or ignore the noise)

this may mean your catalytic converter is broken and the rattle from the exhaust hanger that could have broke when the catalytic converter was struck by hitting a speed bump too hard or a curb.
