If your expedition is a 4wd have the front CV joints checked. The 4WD models have auto 4WD that sometimes lock into position and don't unlock ~ even when you don't 4WD. This have very negative effects on the front wheels when turning (especially at lower speeds on 4WD high).
Dead battery if it is having trouble turning over or the starter motor is going out. Check the battery cables and ground straps at both ends for corossion
Wheel speed sensors, or your ABS Sensor on rear axle housing if so equipped
That would probably sicking calipers or warped rotors or both
Auto Zone will check your computer codes for FREE... And go from there.
without more information i would say it sounds like the wheel bearing.
If relay & fuse OK then you will need to remove overdrive solenoid from the side of the gearbox and clean it - gunk can build up around the small holes stopping the flow of auto fluid therefore stopping the gearbox going into overdrive. It can happen intermittently until orifices block completely .
brake switch ???
If the odometer also quits, the problem is probably the speed sensor or wiring to it. If the odometer keeps turning when the spedo quits, it is in the spedo itself and needs to go to the speedo shop.
yes i have a 99 and a 01 expedition both stock with 33x12.5x17 on them the only problem is you got to watch turning i put 3/8 spacers in the front so they would not rub on the inside
The battery needs to be replaced
A bad wheel bearing also when turning it sounds worst or straight driving
5 speed or automatic?
