Rear wheel bearings

[boristhebold]

I am having all four discs,passage and sensors replaced shortly, there is a droning noise at the back end that I presume is worn wheel bearings. OE or aftermarket? It's an 07 coupe.

Before you spend the money Check two things.
Uneven tread wear on the tyres feathering for example I have experienced very similar noise from certain brands of tyres when they wear.
Jack the car up on the corner that you suspect. Check there is no roughness or noise from the wheel as it turns by hand. If nothing check the other side in a similar way as the noise can transmit over the axle
Oh three things actually........... check your calipers are not binding. Binding will increase as the discs heat.
Any quality bearing kit should be good if you find it is the bearing
Good luck.
