I have an awd rx 330 with peformance packageand currently has 2000 mi..After a 700 mile round trip to Destin,Fl.my wife noticed this loud squeking or creaking metallic sound which appears to be coming from the rear driver side of the vehicle when going through a curve at 30-40 mph and gets louder when applying the brakes.I noticed it too this evening .Any body that has had the same problem?Any thoughts on the cause of this will be very much appreciated.I have informed the dealer and was told to observe if it persists.
