Is yours a V8 with full time AWD?
Or does your switch say "Auto 4hi 4 lo"?
Either way, leave it alone. The "Auto" feature only engages when the rear wheels slip. It is fairly smooth, and will keep you straight most of the time.

As previously said, 4x4 Hi gives you manual control while Auto engages the front wheels automatically. But please note that you can't drive a vehicle like this in a 4hi mode on a road, unless you are going slowly and the road is REALLY bad (like deep snow etc.) Driving on a hard surface in 4hi or 4low will result in damage to your transmission and possible loss of control as there's no central differential in Explorer, so when you turn, the tires will have to slip. Auto is for road conditions, though bear in mind that until your rear wheels slip, it's a purely rear wheel drive car (and then it may be too late), so driving on slippery roads should be very careful, regardless of 4x4 auto. I had such a slip once. There's a 5.0 version with AWD scheme (viscous clutch), it's less likely to slip, but, on the other hand, you cannot control 4x4 there at all, so it's not for offroad.
However, if you mean just disconnecting the front wheels, 2wd mode, there's no such option starting from either 1997 or 1998. But I don't see any reason why you should want it, it gives you no advantages and doesn't save fuel, because the front wheels are engaged only when the rear ones slip.

The reason I want the 2wd option is mine tries to go into 4wd driving down the highway , randomly. I have taken it to several Ford dealers to have the system diagnost , there have been no faults detected. I keep the transfer case unplugged at this time , but would like to correct this issue. Any thoughts ?

So you just drive on a straight road and suddenly you feel that the front wheels start working too? Or it's when you turn? How do you know that it has engaged 4x4?
As for the reasons, well, I see one which is pretty obvious. The car must receive information about the front and rear wheels speeds from some sensors, tbough I am not sure where they are located, but it's possible to find out. If it suddenly engages 4x4, it means the car thinks that the rear wheels are slipping. I don't think that the rear wheels sensor suddenly starts showing a very high speed, but if there is some problem with the front wheels sensor or its wiring which makes it suddenly stop sending signals (or the signal becomes much weaker), the car may see this as rear wheels slippage and engage 4x4. And this may be an intermittent problem which appears and disappears, so the dealer may not be able to find any error codes. Also, the car may not see it as an error as such, just as wheels slippage, so maybe no fault codes are recorded at all. So my thoughts are to find out where the car gets wheels speed information from and check these sensors and their wiring.

The HALL sensors are in the back of the transfer case....
Make sure your tires are all inflated to the same pressure, that the tires have good tread and are even in circumference..
Drain the fluid from the transfer case and refill with a good quality ATF, remove and clean the hall sensors... Philip
