Switch my ford exxpo into 4l or 4h and then back to normal. now the back tires grab when i turn.
Thats odd. It would make more since if the front tires were grabbing. If there are NO signs that you are stuck in 4x4, then you may have a limited slip differential installed in the rear chunk. Normally when you turn a corner the inside when spins slower than the outside; the problem with that is when you get stuck, the differential acts like you are turning and sends all of the power to one wheel. So sometimes for traction, a limited slip differential is installed, so that when one of your tires starts to spin out, the differential locks up and sends power to both wheels. It is only supposed to do that when you are spinning a tire in the mud, or peeling out. But, sometimes the limited slip gets a little unlimited and needs to have new oil, or be replaced. You may also have a full locker, which is engaged by air or electric signal by a switch(sometimes the 4x4 switch), and it could be locked up. Either way, if they are locked up, when you turn both wheels will turn the same speed and you will know it. It could also be a brake problem. It would serve you best to have a proffessional look at it, as a brake problem is always a serious problem. Good luck!
