This was my situation as well. I had nasty howling coming from the front right when I was at highway speeds. You could feel it in the gas pedal it was so bad. The weirdest thing was that it came out of nowhere. Like no warning, just one day got loud. I jacked the car up to inspect, and the wheel bearing had 0 play, none. Rotated quietly and everything. I replaced it anyways knowing that was probably still the problem, and it was. Go figure.

To the OP, glad you found your problem.

 

now i have to check my car. lol. it was doing the same thing but on left turns. then it went away after awhile. I even took it to the dealer to take a look and they found nothing.

 

If your lugnuts were loose and you heard the grinding, check your rims for any scraping on your caliper. it does depend how loose the lugnuts were but if your wheel was wobbling it make have scraped against your rim.

 

I really thought this was going to apply to my problem as well. I have some sort of noise coming from the left wheel when making sharp right turns only. The sharper the turn, the more noise it makes. I shook the wheel looking for evidence of a bad bearing, but no play. I peeked around the wheel with the front end in the air to look for any rubbing with the fender liners and didn't see anything obvious. I guess I'll check out the backing plate next.

The sound almost sounds like tires scrubbing if you've ever heard that on a car with REALLY BAD alignment. (The alignment on my car is near perfect.)

 

good think u found it quick but I always torque my lug nuts to be sure they are tight.

 

Yeah, if I had a torque wrench I would but I don't.

And it wasn't nearly as bad as it could have been. While I could finger tighten/loosen all the lugs, it wasn't to the point where the wheel was wobbling. I checked my calipers and didn't see any major scraping, of couse I have some usual fading in a few spots.
