Grinding at low speed full steering input

[Ignignot]

2008 GX470, no KDSS, recently refreshed factory suspension. When I am turning as tight as possible in a parking lot I get a grinding and hesitation out of the front end. Sounds and feels like its potentially the diff binding up. Happens when turning both left and right, starts at about 95% steering input. No problems whatsoever until I get close to full steering input.

Any advice or things I should check are apprecaited. Diff fluid was changed last fall with Mobil 1 75-90 synthetic.

Correction, its only on sharp right hand turns. Im suspicious my skid plate might need a little bending

It's probably a tire contacting something. I'd check for rubbing marks in the wheelwell and on the frame.

it was the skid plate on the drivers side. I bent it back up and the noise is gone.
