Vibration noise when over 40mph

[Tim85]

I've developed a constant vibration noise at the rear of my A3 2.0t. It sounds a bit like the tyre is rubbing. (It isn't, I've checked) so I just wondered if anyone knew what it might be? It gets a bit annoying as the quicker I go, the louder it is!

anything loose in the rear arches or underneath the back that's catching passing air maybe?

 

[Tim85]

Not that I can see. It's a weird one, only started happening after the cars MOT a week or so ago

It also makes a bit of a grinding noise when I corner right.....but only on a fairly tight turn

Could maybe be the doughnut coupling.

Ive checked the near side rear wheel and it seems a tiny tiny bit loose. Could it be the bearings??

Probably, yes.

Yep if you've got movement in it then your bearings will be the cause of it yes.

Was the bearings! Thanks
