When a wheel starts slipping does it simply apply power to the other?
-Jesda
depends, there are 3 main types of lsd. clutch type, helical, and viscous.
in a clutch type, there are clutch plates that are preloaded with a spring on both sides of the spider of the diff that force the wheels to turn at the same speed, unless making a turn.
helical has a complex setup of gears within the diff case that can transfer a predetermined amount of power to the wheel with traction. [helical lsd will not work with one wheel in the air, both wheels must have some degree of friction]
viscous units have a device thats filled with silicone viscous fliud that heats up when one wheel spins faster, becomes stiff and locks both axles together
