Thank you mate, but you can’t fit the wheel bearings wrong. They just bolt on and torque up to required setting. It’s definitely front, I reduced front pressure from 37 to 31 which has helped a little, it seems the higher pressure amplified the drone, acting like a microphone. It is road surface dependant, which is bizarre, I opted for the Goodyear as every seems to say they are the quietest. I still have my d3 so I might try these wheels on that to totally eliminate it, but as I say I tried the d3 wheels on here and noise was the same. The D3 is silent and travels round like a magic carpet! I have a bmw m3 with race suspension and track tyres with ridiculous geometry and I think it drives quieter than the d4......I’m going to change fluid in front diff also as I didn’t realise there was on separate to the gearbox
