I am new to 4WD systems. I have had various cars with AWD, but never a 4WD system. From what I understand on the Tacoma there is no center differential, only a transfer case. Because of this the front and rear wheels are locked at the same speed, so there will be wheel slippage going around corners.
How should I drive the truck this winter, say when the roads are mixed with ice, snow and dry patches? Is it safe (non damaging) to make a 90 degree turn in 4WD if the road is dry? Frequently in New Hampshire we have rods that go from snow, to ice, to dry depending on plowing, traffic and sunlight on the road. It would be nice just to leave it in 4wd on days when it is mostly snow and ice, but this seems like a bad idea. I am tempted to just treat it like a 2wd car and put it into 4wd when off road, or on really snowy days.
According to Toyota we can drive the truck up to 55mph in 4WD mode. Realistically is this only on the highway where it is mostly straight line driving?
Also, why doesn't Toyota add a differential, with locker, in front of the transfer case? Seems like a simple thing to do to give you more flexibility. I would have paid a $1000 more for that.
