I believe the axle on one side of the differential is separated in to two pieces. There is a spline that can slide over the two axle pieces effectively either locking the axle up or allowing the two pieces to rotate independently. Someone correct me if I'm wrong.
I just let my lights hyper-flash. I kind of like it because it will usually flash normally a few times then go hyper. It's almost like if I don't complete the turn quick enough my truck gets impatient and starts quickly tapping it's foot.
Someone mentioned to me that it could cause something...
I just received a press release email from ARB. Looks like these are going to be available shortly if they are not already. They don't mention the 4Runner as a supported platform but they do reference the FJ so they should work.
The KM2 would have poor wet traction based on their design. However, if you get them siped their wet traction will improve to at least "good". Siping KM2 is pretty much a requirement if you drive in wet/snow.

I haven't sealed up the drain hole yet. I figure any rain I suck up right now is going to precipitate out of the air flow and drain out of the drain hole.
I figure once the drain hole is sealed the water will still precipitate out of the air stream but then will collect in the box. That could...
The FTS snorkel doesn't seem to have the same water shedding setup as the safari snorkel. Can you independently purchase a better snorkel head? Could you even suck down enough rain water that it would matter?
I finished installing mine today. I posted the info over in the FTS Snorkel Install thread: http://www.toyota-4runner.org/5th-gen-t4rs/164189-fts-5th-gen-snorkel-install-8.html#post1745528
I got mine installed:
For those with the TRD CAI you'll want this part to mate the snorkel to the CAI box. It fits perfectly and you won't need to RTV anything (except maybe the little drain hole in the bottom of the CAI): Amazon.com: Spectre Performance 9741 Black 4" x 3.5" Intake Coupler...
