    I have a 99 tacoma trd with 99k miles on it I just got a week ago. When I put it the truck in 4 high and make a sharp, slow left or right turn it almost feel like the tires are rubbing and the truck kind of lightly lurches forward? It does not do this in 2 high. What could be wrong?

    did you have the 4wd engaged on pavement? if so than the 4wd system was binding

    Yes, I was on the pavement when I was turning sharply/slowly but it was snowing out so I engaged the 4wd in case the roads got slippery. And just realized I posted this in the wrong section.

    .
    When you are in four-wheel mode, both tires are driving at the same rate, when you turn, whatever tires are on the inside of the turn rotate slower that the ones on the outside, but they are still wanting to spin at the same speed, hence the 'jerkiness' you describe. Because of this, it's very important to the life of your drive train to only use four wheel drive on surfaces that allow the tires to break traction if they need to. If you drive like that on hard surfaces, this will cause the drive-train to do what's called 'binding', a nasty thrashing of your drive-train which can ruin it.

    its completely normal...unless it is really slippery out..I would be careful about engaging 4wd on pavement.

    no you can engage it whenever. Just don't try and turn unless the tires can slip (like in soft dirt, ice, snow, etc.)

    Well, yeah, off-road in dirt or mud, snow and ice on roads is OK, just have to be aware of what the road conditions are suitable for four-wheel drive. If the conditions improve or start to dry, put it back in two-wheel drive. Basically use four-wheel drive on pavement only when you absolutely have to. Like Pete said, I wouldn't turn too sharply either, it's just tougher on the drive-train.

    The tight u-turns and fast tight 3 point turns are not for 4 wheel drive.

    More radius turns when engaged.

    That's why you have a front & rear diffs.
    The problem is caused by the front wheels covering more ground than the rear wheels on turns.
