Wrx GC8 unknown Rear End noise

Hi there everyone, hopefully someone could can shed some light on my situation, obviously diagnosis will be difficult without seeing the car in person, but ill try and get a video where you can hear the noise that is driving me nuts.

The Situation:

Over the past two days my V6 STi has develop some bad noises from the back of the car. First of which is a squeaking/ creeking noise, first off i figured it was no big deal as i thought it was probably just sway bar bushes. it appears to turn out the its most probably coupled with what every is causing the second noise, this being a rubbing noise coming from the back of the car(possibly rear hub?). this rubbing noise is the best way i can think to describe it, or a light grind. this noise is most noticeable on deccel at low speed (<30kph). the noise has a rotational frequency too it as something rotating is rubbing. My car also has the rather common knocking shock issue weather that has a bearing on anything.

My suspicion is that it could either be my wheel bearing or potentially a blown center or rear diff?

Any Input would be awesome. ive already lubricated the sway bar and it had no effect

will be something between the bumpers

Way to hard to even think about a diagnosis for this

it sounds like what i just had and it was a wheel bearing for me..

just a weee update. the rubbing noise was the stone gaurd rubbing the rotor, i gave it a little bend and now no rubbing. however the squeak has got worse. managed to catch the squeak when the car was idling in my driveway so i grabbed a video of it. the squeak is a little hard to hear over my exhaust but is noticable. this very well may be in the wrong section now as i suspect it might be the trans mount?

noise is most noticeable at the end of the vid.

my guess is check the exhuast for fouling somewhere

Pretty much nothing else is moving at idle under the car where the vid was taken

Once again it looks like you need a beer haha. i seem to find whenever you post on here your always right .

after some further investigation and some lubricating of every bushing i could find i found a snapped exhaust mount.

the one that attaches to the bottom of the transmission to be precise. Thank you for your advice
