Grinding noise when turning right issue
3 Attachment(s)
When I searched for this problem I didnt see alot out there so Im posting what I did to correct the problem for anyone else searching for answer. Subaru apparently is instructed to just grind down the inside lip of the rotor. I flattened the dust shield with an air hammer. took a few minutes. No noise now.

Might have nothing to do with you problem but ill throw it out there. But at Toyota on the tundras the rear rotors get like that because.... Bad wheel bearings

Only when turning? Hmmm, it just might be what hawk eye said if that's the case.

The tundra is exact same problem. I bet if you put new rotors on the noise will be 10x worse because the metal is closer to the backing plate causing it to rub all the time. Does the edge of the rotor that create the labynth seal ( creates the seal between the edge of rotor and backing plate) does that look shinny ?

OP, can you please pull the wheel and examine your hub.
This can be a dangerous issue if let go.

Please respond after your findings.

just take those backing plates off. haven't had a problem in 10 years...

you [I]should [/I]double check the wheel bearing slop though. takes minutes to do all 4 corners.

Yea no play in wheel bearings although a bad wheel bearing would make sense why this would happen. Its a common problem apparently which is why subaru grinds rotor lips down instead of replacing wheel bearings. Cutting or chiseling the dust shield out is just the easiest way to fix the noise. Removing it, although more time consuming isnt really a horrible idea since dust and heat arent going to affect close components like the front. In my case, removing it wouldnt affect much since it basically looks like swiss cheese now.
