Rubbing Noise, What did I do?

I just changed front brake pads on my stock 03 SR5 V8. I have changed brakes in the past, but never messed anything up until now.

I put it all back together and now I get a noticible rubbing noise fron the left wheel when driving and turning left, and very slight from the right wheel when turning right. No issues driving when driving straight.

I drove a few circles hanging out the window like an idiot trying to get a fix on where the noise is coming from. After I parked I hoped I could find some visual signs of friction to find out where it is coming from. Nada. It sounds like maybe the dustguard rubbing on something, maybe the rim. Maybe I bent the dustguard when re-mounting the tire or bumped it with the caliper? I would think there would be visual signs, but right now i am seeing nothing to indicate.

Any ideas?

Any rubbing on either the mud flaps or the fender liner should be very visibly noticeable, especially if either are already dirty and don't have any rub marks. My guess is you bent one of the dust shields.

I pulled off the left tire. It is the caliper rubbing on the the rim. I never removed the disk, but I figured maybe it was slightly off and I did not torque the lugs down enough despite using a star pattern. So I tightened them a bit, and the noise got much queiter but did not go away.

So I went to torque them down a bit more. Nothing crazy, but definately to ensure everything is seated properly against the hub.

Then on the last lug doing the star pattern I stripped the stud. F......

If the noise is very "tin-y" then its usually a dust shield that got banged in toward the rotor when installing the wheel. If the noise is more high pitched and "squeal-y" then I would disassemble the brakes and take a closer peek at the pads and how they are seated. Ive had many sets of pads not slide in the caliper smoothly. Perhaps clean everything up and put some grease on the pad slide hardware. Also be sure that the wheel was seated flush against the rotor and nothing is behind the wheels hub mounting area when you torqued it down.
 
I replaced the stud I stripped out, then once again put it all back together. Same issue! Caliper is scraping the rim. Stock rims, stock rotors and calipers. Nothing changed besides new pads, and that should not affect the top of the caliper scraping the inside of the rim.

I circled the part of the caliper I am talking about. Both caliper bolts are seated properly. Lugs are tightened in a star pattern.

It only happens when I turn hard to the left.... Is it a hub issue?
 
It's not possible for the rim to rub on the caliper "only" in a turn. They're both going to be turning at the same time. That's probably not your noise. Jack up the front, throw it on stands. Move the wheel back and forth full lock while rotating the tires and you should be able to figure out what's hitting. I'm still betting on the dust shield. Something would have to be seriously off for the rim only to hit the caliper during turning.

I could swear that that looks like you have the rear caliper on the front .

Sorry I should have mentioned, this is a random picture off google. I only used it to point out what part of the caliper is rubbing against the rim. I do not have rear calipers mounted on the front.

Yes I double checked and it is my noise. I am going off the fresh scoring on the inside of the rim and the fresh scoring that is on the top of the caliper. And yes, it is only happening while turning hard left. I am positive now it is not the dust shield. The rubbing is audible, but has not caused significant scoring over the last 100 miles now. I could probably shave a mm or two off the caliper and it go away, but I would rather isolate the problem them jerry rig it.

I can try and get some more pictures later to show exactly what I am looking at if it would give you the warm and fuzzy that I am not a complete idiot trying to put a rear caliper on the front.

Ok, taking this at face value, when the wheel and caliper are correctly installed they DO NOT move relative to each other, (other than the wheel spins, obviously). To get what you're describing, they must be shifting closer to each other when you turn, so one or both of them is incorrectly installed.

I'm guessing the caliper is shifting, because there'd be fifty kinds of hell if your wheel had that much play on the studs.
 
could that be your hub bearing? it might be loose.
