How does my diff work?

2012 GTS. Pulling out of my drive slowly and turning full lock left to keep to the left of the road as there's a blind bend close, I get a chattering from rear left wheel area. (Not the wife!!) Never happend before but last twice I've been out that way, it's done it.
Like the diff is locked and it doesn't like the sharp turn, tyre perhaps skipping?
I'm not sure how diffs work so don't know if it's causing damage and needs sorting. Doesn't do it any other time so maybe when the diff warms up it sorts itself?.
Any thoughts?

Yes, Pzeros. But not sure how would swapping tyres change issue?
The difference in wheel speed means that the diff will try and lock the wheels together. The tyre grip is low so the noise is the tyre slipping on the surface. When it is or the tyres are warm have more grip and so it doesn’t slip.

What it really means is your diff is working.

So nothing to worry about! - excellent, thanks.
