Need professional dash rattle help

Postby Rych » Mon May 24, 2010 2:18 pm

Well I have this really really annoying rattle coming from the middle of the dash somewhere around where the gear stick rods go into the firewall.

I've pulled the dash out and looked everywhere, held the revs to make it rattle and can't locate where it is coming from. When driving it starts rattling around 3 - 4k rpm.

I must find, it is driving me crazy! Any special techniques to locating the exact source of a rattle?

Thanks heaps!

I don't know how sure you are it's coming from within the cabin but I had a noise coming from directly below that same area and it turned out to be a heat shield on the exhaust that had come loose. Worth checking I guess

I had a rattle that i was CERTAIN was coming from the far left corner of the dash. Turned out it was the busted up catalytic converter in the exhaust!

As suggested above, check all the heatshields on the exhaust, but also don't confine yourself to looking in a single area of the car for the cause, as the sound can travel to another area of the car it seems.

Yea that is true, just it's a small rattle, like a loose screw sound rather than something big. The reason I am pretty sure is I can hold the revs in neutral at around 3k and put my head right up to this area and it sounds so so close but possibly behind that big white plastic heater cover or something.

I'm not sure how easy it would be to take that apart..

Well I have sourced the rattle finally after removing the center console and unbolting the gear stick.

Rattle is coming from the yellow area and is the smallish metal casing the gear changer rods go through sorry I don't know the names. But I can't make it stop the rattle, I can push it to make it stop but once I take my hand off there is no way to stop it rattling..

Any suggestions, could get replacement or take it completely off somehow and examine?

Cheers.

There is always a way to get rid of a rattle, its just a case of trying until you get it right. Can you glue it to whatever it is rattling against? can it be screwed down better? if it's a reasonance rattle try sticking some sound proofing to it or putting a dent in the metal to change its behaviour.
