Grinding when turning left

2006 LR3 SE

Grinding noise when turning left (mostly). I can feel it under the drivers footwell. I've looked over every damn square inch under the truck, nothing is loose. It sounds as if something is rubbing as I'm turning but there's nothing there. We're running 265 65 18 tires which are slightly larger than stock, however, the sound was there with stock tires as well.

Any ideas??

I had a similar issue with my 06. Turned out to be the passenger side rotor cover or whatever that metal shield is around the rotor. During left hand turns, it would put stress on that side of the truck and cause the shield to rub on the rotor. Take the tire off, knock the shield back in a few places and see if that was the issue. Worked for me.
