We have exactly the same problem. Scraping on right hand turns. This happens sporatically. When it appears, it stays present for the remainder of the trip. It only happens at speed on right turns. The higher the speed for a given turn radius.. the louder the scraping sound. The sound does NOT happen at low speeds like in a parking lot. At 10-20 mph the sound is usually not present and if it is at this low speed it is very quiet. Very noticable at 35 mpoh and above on a circle. There is no knocking, rumbeling, or ticking. It is a metal scraping sound ONLY on fairy tight right handers
