Question about 1998 Ford Expedition
I have a 1998 Ford Expedition that just had the shift motot and 2 hall effect speed sensors replace by a local FORD dealer. Now when the truck is in 4AWD mode, the 4WD engauges at a speed between 2 and 8 MPH when turning. It never did that before, but the dealer says that is normal. What concerns me is that when the $WD engauges, it feels like it is engaugeing at the front wheels, not at the transfer case. And when it engauges, it does so very hard. So hard that the whole front end shutters. Where should I start looking as far a s a fix.
Go back and talk to the service manager. If he wont do anything go to his higher up.

Its weird but I had a fuse blow out awhile back that is the same fuse that works the cab lights when you open the doors. When this fuse went out it also made it shift odd and hard when it did shift. Since it is only intermittent in your case, It may just be a weak fuse.

it is not a speed control sensor it is a speed sensor. it needs replacing when it fails. the problems to look for from it failing would be intermittent or no speedometer or cruise control kicking in and out. these sensors do not fail very often they are just a prox switch picking up metal tabs on a ring as they pass by the end of the sensor

First you should check the ground cable and ensure good contact. Second make sure the battery is fuly charged (over night is best on a slow charger). It looked like you said a new battery so a good charge should fix it if it is the problem. I assume you have good connections on the parts you already changed. It is probably a bad starter (motor). You can remove it and have it tested. If it is good you might have an internal engine problem. Try turning the crankshaft. It should turn by pulling on the drive belts. Well it sounds like a bad starter.

Encoder motor located on the transfer case is usually the problem. It is the motor that shifts the transfer case.
