Full time wont bind due to the center diff unlocked (in the case of the 4runner and FJ a 40/60 torsen)...
Itís a drag when basic terminology gets confused by marketing people because then it gets difficult to even have an intelligent conversation. Itís my impression (and I havenít studied this carefully) most car companies in the past have called a basic center differential setup AWD. 4WD, on the other hand, is a term that was reserved to describe a rear wheel drive vehicle with a transfer case that only allowed the front drive shaft to turn when you shifted the case to 4WD. Yes, there have been some variations on this theme not worth mentioning; but when car companies start calling AWD (or something else like Jeepís Quadra Trac, for example) full time 4WD, I call marketing bull shit. Donít fall for this nonsense. 4WD and AWD are not the same and there is no such thing as "Full Time 4WD" as you correctly point out. And, of course, AWD with a locked center differential is functional exactly the same as 4WD.
I am just saying this to clarify the terminology. I believe we are saying the same thing even though I find some of your language confusing. I am sure that most of us have found that 98% of the general population does not have a fawkin clue about the difference between AWD and 4WD and canít understand it even if you explain it to them with endless drawings and diagrams shoved up their arse. On the other hand, I believe you and most others on this board understand it very well.
That said, things do start getting interesting when you start adding and mixing gadgets like diff locks, LSD, and computerized brakes that are programed to control spin and slippage.
I think myself and other were surprised that Toyota used AWD with the manual rig and a basic T case with the auto. I dunno, maybe thatís not odd, but it surprised me. I, like you, really wanted regular rear wheel drive for basic driving for a number of reasons I wonít get into; but, I wouldnít have given up the manual 6 spd to get it. Short story, now that I have been playing in the snow with the AWD with the traction/stability control, I am about to be converted. Iím telling you, IT ROCKS.

This part doesnít sound correct to me. I didnít think that the auto setup has a center diff. Can anybody help with that?
