2009 143k miles. Noise happens under load while in drive. I typically notice it when driving in neighborhood streets and when I accelerate (even a soft acceleration).

In the video you can't hear it at first from the top, but at 0:16 I go down underneath and you can clearly hear it. At this point, the car is in drive and under medium acceleration (brakes on of course).

Toward the end, we put it into park and accelerate and you can't hear it.

Any thoughts on this? I was initially thinking idler pulley bearings, but it doesn't appear to be localized there.

Thanks for any input!

 

Mystery solved...Turns out to be the cuffs around the exhaust. All 4 have broken loose and when you accelerate the whole engine shifts backwards and they lean and start to rattle.

Any thoughts on what to do with those cuffs? Should I take it to an exhaust shop and have them fixed? Or just cut them out?

 

Any thoughts on what I should do with these? Should i take it to an exhaust shop...anyone know if they're repairable? Or should i just cut them off?

 

Mine are all loose too, I just leave them be. But the local mechanic said I could cut them off without issue YMMV!

 

I feel like I have this same exact issue. Only two cuffs were loose when I went under the car so I cut those two off but still getting the rattle. I might take a look and see if the other two came loose as well.
