Now, I don't know how it is possible if you are viewing your vehicle from the outside you would "see all 4 wheels spinning at once" Xray vision??? two on one side maybe. Then two on the other side maybe? Now, even without LSD it is possible to get slippage from both wheels equally, but very rare, only when all 4 see completely equal grip........they may all turn, but after a part revolution computers will quickly reroute the power to the ones (front/back) with the most grip, and that is constantly changing.

Pretty simple... bend down.. view the truck on a angle.
Park the truck on fresh gravel, and accelerate (noted by marks left behind), you will see with good tires that power went down to all 4 tires (Traction Control off).
I’m not talking about “Stuck” conditions, but slippery conditions, with the vehicle moving forward.
Now, don't confuse off-road conditions with slippery on road conditions. Deep mud, and you'll get a lot of 1, 2, 3 tires spinning as Terry said.
With 4Hi, power does go down to all 4 tires, unless your tires are garbage or you are in stuck situations.
My SUV was a different vehicle with all season tires. With 4 aggressive snows, it’s completely different. There is a great deal of lateral stability and acceleration, something even the Audi AWD’s can’t match. I’ve tested it with my neighbors.
Since the 4Runner has 4HI, 4LO selections, I would definitely get one!
