(The gear box is a 6 speed manual by the way) Can't turn the radio up!, since they did the gear box, they had to disconect the battery and the radio code I have is not the correct one, so no radio !! :) (but thats another story!) Sparky Paul, some good info there, thanks....Most of it I can pretty much rule out with all the work and checks Ive done but the bit about the half shaft bearing has got me thinking! I did unbolt it recently and spun it as best I could while it was still on the car and it felt smooth, but how about I remove the bolts or slacken them,and take it for a run, see if it changes the noise. I'll give it a go. I used to have a Scorpio 2.0 L so I know all about turning the radio up,.... To cover all the noises it was never turned off in that car :D Thanks guys
