I am trying to understand more about limited slip with respect to the 2004 Xterra.

My father has a 1991 Toyoto Land Cruiser, which has a viscous coupling in the transfer case. This makes it so that even when he doesn't engage his lockers, one wheel slipping on one axle will NOT prevent the other three tires from getting power.

What I am wondering is if (for example) I got only a limited slip for my rear differential, what would happen if one of my front tires was off the ground? Would my rear tires still get power and propel me forward, or would all my power get dumped into that one wheel that is off the ground?

Thanks for any info.
