Hi, I have a problem with my manual 4x4 2013 SR Hilux and was wondering if anybody has had any similar problems or may know what the problem may be. When it gets up to 80kph it makes a whirring or humming noise. It continues up to 90kph but stops after that. Also stops when I depress the clutch. Makes a sound like it is winding down. Have had it at mechanics. At first they thought it was the spigot bearing/ clutch so put in a new clutch. Then put in new gearbox and the noise continues. At this stage they are not sure what it is. Has anybody had any similar issues or know what the problem may be? They are thinking maybe, center bearing or Diff but not sure.
