Yes I have replaced nearly everything at the front end to no avail.

I have tried swapping alloys and tires with a friend (OE 168 alloys) and still the same.

Tyres are all mounted correctly too.

I have not replaced wheel bearings as of yet but a few trusted mechanics who have had a good look round the beast have all said the wheel bearings seem fine as there is no movement and the 'normal' bearing whine you would hear is not present.

I'm at a loss at the mo.
