2000 Ford Explorer 6 cyl Four Wheel Drive Automatic 147500 miles
Hi, My 4wd high and low lights are flashing. Also, when we turn into parking spots and sometimes on curves the front tires lock up like the 4wd system is trying to engage causing a jerking motion and making a really horrible sound. It gets worse when we have been driving around a while. We have three different types of tires on the car and only one is all-terrain. Thanks.
