They ended up fixing everything, and there is a "Rattle valve" on the driver side axle tube that vents pressure. well, they replaced it with a open atmosphere breather tube. problem, is that the tube was leaking tranny oil all over. they ended up puttin gthe rattle valve back on the next day as it needed some kind of EFEP (no idea) sealant.
when i had the tube on, no problem other than leaking oil. (bad)
now i have the rattle valve back on, the noise is back! AND WORSE. i have a video on my phone, and i'll have to find a way to link it to here so you can hear it. yea, its pretty obvious even from an iPhone camera and mono microphone. but the problem is back... wtf.
