Ive got this droning noise at about 60-70mph i notice especially when the wheel is being turned to the left. I do have a warranty on the car and it has all ready been in for wheel bearings although i have changed from that garage because i havent been happy with previous work that has been done. I dont no what wheel bearings they changed it may have only been 1 which was done, also changing gears is ok although reverse can sometimes grind a little but is ok if i release the clutch and do it again...
