I concur with Dave.
WTF is all this. It went from a thread that should've been locked to a thread that is full of misinformation.
I'll end this right now.
Open diff = one wheel will rotate the opposite direction.
Vlsd/1.5/2way = Both wheels move in the same direction.
Helical= When one wheel slips, the one with more traction gets more power.
LSD stands for lysergic acid diethylamide
But it also stands for LIMITED SLIP DIFFERINTAL
An open diff is not and will never be considered a LSD.
Learn how to fucking search.
And if you STILL don't know how to figure out what type of diff you have, drive to california, and I'll tell you for $50.
I request this thread be lockd for misinformation, and overall bs.
