I just got the truck listed above. This morning I threw the 4x4 on just to test it out (on pavement). It seems to kick in fine and drive ok until.... I make a turn. When I turned left fairly hard the back driver side tire start screeching a little bit. Almost like I was tapping the break and the back tire caught but the front kept trying to pull it therefore making the back tire screech. It was not a constant screech but more like a chirp. This happened in both 4low and 4high.

I've had 1 4x4 SUV in the past and know a few guys with it but have never seen this happen. What could cause that and if you know, how long or (roughly) how much for repairs? Any advice is appreciated!

Check your tire size,, make sure they are all the same size tire,, and in addition different make of tire , even though it says that size is the same , being a different manufacture, could actually be a different height.

Well... I just learned something that I probably should have known. You can't drive on dry pavement in 4x4? I read the manual and it didn't say that.

Did it do that just because I was turning on dry pavement?
I'm getting ready to go out and check the tires.

It depends on how fast and how sharp of a turn. On a sharp turn , the rear tire has to have the
ability to" slip" because of the radius of the turn on the front tires is not as small of a radius, compared
to the rear radius.
Also check tire air pressure..

The screaching tires is entirely normal. In fact, most times driving with 4WD on on dry pavement will make the front tires "hop" as you turn. As jgate mentioned, it's because the inside tires are taking a shorter path than the outside tires, and the rear tires overall are taking a shorter path than the front tires overall. Since the front and rear axles are tied together when you have 4WD on, you can see why one tire will have to skip to catch up with the others.

It's also hard on the differentials and the transfer case, so not only is it a disturbing ride, but it can cause permanent damage. But, since you did experience the skipping effect, you can feel pretty good that it actually works.
