any luck with this I've had the same. It started with what sounded like road noise its now louder with vibration and knocking whether in gear or neutral, did wheel bearings back in june so discounted these. replaced driveshafts + intermediate, no difference. the bearings were cheap so suspected them, replace drivers side with skf and new strut, no difference and the cheap bearing looked in good order! tomorrow the other side will have new bearing and strut fingers crossed.also it was due for new tyres which were fitted today no difference. originally when diagnosing this I had her up on blocks in gear and engine running the noise was there, any thoughts cheers
