does anyone know if a freelander diff is LSD?

Not as standard, but you can get a Quaife LSD for it.
But brace yourself before looking at the price http://www.motorsport-tools.com/quaife-land-rover-freelander-lsd-atb-differential-p-269048.html

I did exactly that. Bought a £50 diff from scrappy and a £600 diff direct from Quaiffe. Job done. Only pisser is u will need to shim into position with very fine tolerances, so you will probably spend another £50 on getting professionally installed.
