A while back someone here taught me that you can identify an LSD by the fact that turning one output shaft (or wheel if it's still on the car) causes the other one to turn in the same direction, whereas on a conventional diff, it would turn in the opposite direction. This worked on the rear wheel drive car I was fiddling with, but could someone please confirm whether this is also true for front wheel drive cars? I don't see why it shouldn't be, but it would be nice to know for sure. If that's a yes, does anyone know if a limited slip diff was standard on a Mk2 Golf GTI (8 valve, 1986)?
If you haven't already figured out where this is going, I'm trying to establish whether I've just found something valuable in the Golf I'm currently scrapping. Seeing the rest of the car, I'd be surprised if it's been modified, but you never know.
