2000 Honda Odyssey Q&A
2000 Honda Odyssey Question: what can cause a constant rattling noise when the vehicle travels over bumpy road?
A good physical inspection of your steering and suspension should reveal where a noise is occurring. My guess would be that you may have a strut mount with a worn bearing causing some noise. Just a guess. - DaveJHM
Very likely that a strut mount is bad. If the strut mounts have been replaced, I have seen the actual spring seat break and cause noise as well. May have to disassembly the struts in order to pinpoint the location and cause of the noise - Visitor
