How do I know if I have a car with LSD?

[Mattius]

Apologies if this is a stupid question..but...how can I tell if I have an LSD on my car? Is there anything that would tell me (Markings, serials etc). Where would I find them generally (assuming on the axle)?

Behaviour with one driven wheel on grass. If it spins like crazy and the other wheel doesn't you have a standard Diff if the wheel on tarmac is driven you have a limited slip diff

Try a mid 80's Metro Turbo with a LSD. Steering fight is horrid. Understreer hard to control even with my sixteen stone 6'4" build.

Leave LSDs for track professionals and buy a road car with ESP and all the associated electronic helper stuff.
