Hey guys hows it going i have a 07 dakota R/t with a flowmaster muffler and 2" drop shackles. i had the exhaust on it before i lowered it and now when i go over a couple of spots mostly speed bumps i get this rattling/ grinding noise anyone experience that before? The exhaust has enough play to hit the drive shaft if you puch it but i wired tired it back and i still heard it.

Also i get a noise in the dash when coming to a stop that sounds like a a cd changer changing cds

any and all help is appreciated thanks

 

Are the sway bar links and ball joints ok?

I have a rattle that I cannot locate either. My noise is worst when several very small potholes are close together. Best way i can describe it is a chunk of wood rattling around inside of a metal box. Try shaking every individual part you can find under the truck. Perhaps put the frame on some jackstands and play with all of the suspension components as well.

 

maybe swaybar broke happend to me on a 96 dakota

 

Yea ill have to look at it when i get home but it only makes the noise when im moving

anyone ever here the noise in the dash when coming to a stop

 

No that is new to me. Do you have a disc changer? Maybe the g forces being applied while braking are actually causing the changer to move some gears inside the head unit.

 

nope i dont have a disc changer

 

That is such a distinct sound too! Hmm what else could make a noise like that. And you said it sounds like it is coming from the dash right? Can you make the noise happen under hard acceleration too?

 

no it does it only when your about to stop, almost right after the truck downshifts

 

So i took bain64's advice and everything is ok so im going to go back to the shop that put the exhaust on tonite and tell them to fix the exhaust and hope that is the issue.

 

i have the same problem when i hit bumps i think its either the exhaust brackets shifting or the tips hitting my bumper. as far as the cd changer noise it might actually be the mechanisim that ejects the cd from the head unit might just need to change it out.
