It is possible that one of the axels is twisted. I got the same thing with mine when I spun the right rear. Put iot up on jack stand and run it while watching the tires or have some one follow you while driving it. Sure hope I am wrong.
I have done the same to the same exact axle shaft.Stinger said:Yes I am talking about the shaft. I twisted the shaft on the right rear axle by about 33 degrees and it caused the wheel to wobble enough to make the wheel scrape against the dust plate.
