I was told it could be the driveline but I want to make sure.. It's been making this sound for a few months now. Here's a video of it.. Does anybody know what it could be? It's a pretty unique sound im pretty sure theres only one thing it could be. Any help is apreciated! Thanks


Help me diagnose this problem on my 1998 audi a4 2.8l quattro - YouTube

 

sounds like a heat shield or possibly bad cv but sounds like something is rattling in there. It does it when the wheel is straight and when the wheel is turned correct?

 

Does it only do it under acceleration, or anytime you're moving? May want to have a friend drive and you lay down next to it and see if you can narrow down more of the source of the sound. ie: driver's or passenger side, front or rear.

 

That's deff a CV joint mine is doing that now. Replacing the half shaft in mine soon... Get under it and see if any of your boots are split and I bet that's the one. You can usually tell which side it's coming from though

 

Yes it does it either way I go..

 

I'll look under it tomorow but it sounds like it's coming from under the e-brake

 

You actually can't hear it from the outside and it only does it when I start out in 1st gear it makes that sound for a few seconds then stops. Only does this on take offs, and when it's done I can still drive in 1st gear without the sound. Also it sounds like it's coming from under the e-brake

 

I would check the tranny and diff mounts. I'm guessing that on takeoff, the center drive shaft is allowed to contact the body or exhaust head shield. That would account for it sound as if it is below the e-brake.

 

could the center driveshaft be the culprit? popping up further when its not spinning as fast
