1998 Ford Expedition XLT 4 wheel drive switch is frozen in 4H

It\'s electronic and inside or nest to computer on transmission. Electronically controlled tranny.

If your vehicle is a 4 wheel drive, than you are probably driving in 4low or 4 high on dry pavement. Put it back in a4wd (automatic 4 wheel drive) position and this shaking when turning should stop.

If you can't find the 4 X 4 switch, then your expedition is probably All Wheel Drive and it will not have an on or off. If it is "all wheel drive" it is like it is in four wheel drive all the time and will kick in when it feels a wheel slip. Check your owner's manual and you will probably find that it is all wheel drive. Hope this helps.

Most likely the controller module is bad, or the actuator for the front axle has gone bad.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

4L only to be used in extreme condtions
N
4H for off road/snow/ice
2H - normal driving

when switching to 4H vehicle must be stationary, as when changing from 4H to 4L
but it is possible to change from 4H back to 2H while in motion.
when 4wd is engaged a lamp will illuminate on dials telling that the hubs are free wheeling, when changing back to 2H you must press corresponding switch to dis-engage this function

There is another recall for the cruise control. This time it is about transmission issues and wiring to brakes and electrical issues. This could be a free recall repair.

one the transfer case there is a motor on the back side of the transfer case. most of the time that goes bad. if you don't have a trouble shooting guide with a wiring diagram, best to have a mech have a look at it. most of the time they rust and stick if not used a few times a year. best of luck.

Ford has 2 types of 4x4 system engagement. One is a knob on the dash that you just turn to 4wheel drive high or low. The other system is the 4x4 transfer case shift on the transmission tunnel (hump) between the driver and passenger seats. To shift into 4 wheel drive high while driving, just let off the gas and shift transfer case into 4H position, and continue driving. To shift into 4 wheel drive Low, stop the vehicle completely, put transmission in neutral, shift transfer case into 4Low position, put trans. in gear, and start driving. I am assuming before doing the above, you have locked in ( turned the front hubs to 4 wheel drive position.) Any further questions, let me know.

no you have it reversed....if the light is on its in awd if its off its not

4-wheel high or 2 wheel if it has it
