OK: About the rear end creaking sound. Someone posted (Problems/Maitenance) that they had their dealer do a check with the 'Electronic Ears' and found a few creaks, squeeks and rattles in the rear end area. One of which was the Rear Axle Flang. I've had this creaking sound since I got my car. I finaly got my dealer to look at the rear right axle and sure enough thats where it was coming from.

If anyone is getting this sound when accelerating/deccelerating, (a little like the sound of a bed spring) get your rear axle flang bolt retorqued.
