1999 AUDI A4 2.8 QUATTRO REAR NOISE

[ROUTY]

Hi Don't know whether anyone can help but i've got a slight droning noise which seems to be coming from passenger rear wheel area it sounds like a wheel bearing noise but i've had the bearings checked and they are fine. I've also had rear drive shaft seals replaced as one was leaking slightly.
Any ideas on what could be wrong

I know it sounds daft but it could just be the tyre. I had one on my car that ended up with 4 slight flat spots on it (for no apparent reason) and this caused an awful drone at motorway speeds. Worth a try swapping the wheels?

Thanks we'll give that a try
Cheers

You were right about the tyres i've swopped the wheels and the noise is now coming from the front. Thanks very much as this was really baffling me cheers
