Help Guys and Gals,

I have a rumble, wheel bearing for sure. But...
Everyone who sits in the car thinks different.
I think front right.
Others rear, some left some right.
Rumble goes away when turning left...
So prob a left one. ( When un-loaded )

But, can't put car in air and run some wheels because of quattro and diff locks etc, as you would for a 2wd with no LSD.
Is there an easy way of sorting out which one to change?

Have tried a long run and feeling the warmest but no result?
Can anything be done with all 4 wheels off the ground?
