XtRmn8 570Nm @1800rpm Donating Members 2,441 Member For: 21y 4m 29d Gender: Male Location: Perth, WA Posted 07/03/10 07:35 AM Share Posted 07/03/10 07:35 AM I have a rattle under my car somewhere that I can not find. It appears to be worse when it is hot, but that could just be me It sounds like a loose bracket that is attached to the body somewhere and rattles only when going over bumps in the road (sharp bumps). I thought it was the exhaust hitting the body somewhere, but if move it around via tail pipes I can not hear it hit anywhere. Also the heat shields around cat section have been removed.Anyone else had a similar issues with their BA or BF ute? This is defiantly not that tray line, but more a metal on metal clunk and it can be pretty loud at times.Cheers. Link to comment Share on other sites More sharing options...

Also check the torque on the U-bolts.Failing that it could be the style side box floor panels "oil-canning" (rolf harris style) against the support rails underneath.

The tray is going to come off soon to do fuel pump and also a bunch of rear suspension work. Will need to do something to address the floor panels also. U bolts I checked and tightened not long ago. I have fixed a few noises so far but this rattle is driving me nuts Cheers Link to comment Share on other sites More sharing options...

But I think its my exhaust heat shields, sounds like crap and you can really hear it outside the car.. Was in a car park with the worlds biggest speed humps and I scraped every single one, think that's the cause.. Link to comment Share on other sites More sharing options...

Try to figure out what sort of road surfaces, speeds, temperatures, and other inputs result in the noise, and whether you can replicate them consistently. Then try and turn the noise off temporarily over the same conditions. For the oil canning, I'd say throw something rather heavy in the back and drive around as a start, with some more complicated disassembly as a further step.
