    Hard to say without listening to it. I'd get the car jacked up, take wheel off and look for any shiny metal & turn hub/disc while listening. Maybe you can narrow it down a bit.

    hello mate x2 what khufu said.

    also is the noise only when going round left hand bends and also does it increase id you increase speed and the angle of the turn? i have had this problem before. some woman crashed into me and it affected the engine mounts. it took them ages to find where the noise was actually coming from. they replaced the drive shafts as they thought it was them so id check them too. then they placed microphones under the bonnet and found out that it was that the inside of the engine mounts, the honeycomb structure had been disrupted. (it was on the left hand side of mine as if you are looking under the bonnet) (so it will be the other side for yours) check for signs of scraping on the outside of the mount againts the connecting part to the engine which is where it was on mine. hope this helped

    My guess would be wheel bearings as i had a similar thing, but when i was turning right. Drive in a straight line at 30/40mph and trun left and right slightly to see if you get the sound to get louder or quiter.

    ARBs are anti-roll bars

    And by mtgs I think he means mountings - specifically the shock absorber mountings.

    Probably the wheel bearings as mentioned above..
    Always obvious when accelerating into a turn.
    If the sound is from the rear then the diff or haldex could be to blame
    Either/or
