Jack up both rear wheels and spin them, if both spin the same direction then LSD..

You can also look at the metal tag.  If it says 's4.10', you're LSD.  They also usually have a large 'S' painted on top of the case.  Hard to see unless you've pulled it.  It might be worn out regardless, the magic doesn't last forever.
