Which are the"drive wheels",the ones with power to them, when in 4wd? Is it left rear and right front or opposite?

4WD = 4 wheel drive.

That means all 4 wheels get the power, in 2WD, only rears get the power.

If you lift your rig in the air and hit the gas all 4 wheels will rotate if you are in 4WD, and only rears will rotate if 2WD.

Watch this vid.

Don't forget though that we have completely open diffs front and rear so whilst power is being transferred to the front and rear wheels 50/50 in 4WD Low it is going to the wheels with least resistance.... so really you could say we are only 2WDs

By this I mean if you end up lifting a front wheel off the ground then generally 100% of the power going to the front is now going to that wheel off the ground. That's why you see 4WD vehicles that get crossed up (one front wheel and one back wheel) off the ground end up going nowhere with both those wheels spinning in the air.

That's where the KK's Brake Lock Traction control comes into play... once it detects that lifted wheel is now in the air spinning it applies the brakes to that wheel, forcing the torque to be transferred back through the diff to the other wheel on the ground and keep you moving forward. It's no substitute for locking your diffs completely with lockers and giving you a true 50/50 torque split between each wheel but is still a great system that works surprisingly very well!

That's right, but I don't think our friend can understand how differencials work so fast, by reading the first post I guess he just started in the 4wd world, and that amount of info is hard to understand in one single day

Anyways, all this is explained in the video above, I love our BLD system.

Off topic: Mikzor, haven't seen new pics updates of your KK lately, don't keep the pics to yourself

Old trick for pre bld vehicles, if you play with the handbrake you can send power to the other wheel as well. It isn't a substitute, but an old trick none the less.

Thanks folks.The video was must helpful.I always assumed there was only power to one wheel front and rear,unless your vehicle was slipping. Thanks again!
