Juddering and grinding noise on full opposite lock??

My 07 f430 makes a grinding noise when at slow speeds full opposite lock..is this normal??anything to do with the lsd??car has a couple of months so fairly new to me this noise...advice welcome

 

This type of query comes up in the Autumn and I usually reply Ackermann effect because it can be due to the cooler rubber on the concrete skipping sideways - Wikipedia has a good article on it

 

I would advise against keeping the steering wheel at full lock for very long or very often. It's a strain on the steering components.

 

I had this on mine when I first got it (Sept last year). New tires fixed it.
