05 PSD noise?

At 185,000 the car in question developed almost a grinding sound during tight turns. On the way to get this checked out, it would make the sound on longer higher speed curves ie clover leafs.

We changed the PSD fluid and the sound went away. It hasn't been changed before. Put in Toyota ws. The fluid coming out looked burnt and dirty but no metal filings.

Now at 200,000 km the sound is coming back. We checked the fluid today and the level is good ad well as quality. The sound will come on the first two turns, but then disappear all day after that.

I'm kinda thinking it is wheel bearing related. Front brakes are worn but I do think theyre shot. Cv joints seem fine and theres no clicking or popping.
