Possibly bad transfer case.
If a GM compact (T) truck, consider a bad 4x4 switch.
If an Explorer you might have a bad contact plate, replace the encoder motor.
Because your transfer case might be shot it could be the bearings..auto locking? get manuals, it costs 100 and u need to get out, but it won't fail you. if electronic 4x4 switch, you need a new switch if manuel linkages, adjust linkages
a range is were a cowboy washes his bull.
your accuater is starting to go its located on the front differential drive safe
how does 4x4 auto work
That would be the 4L60E and yes it will work. The 4L80E will NOT work
Press the low range button again, or turn the 4x4 off all together.
That would be the 4L60E and it is the ONLY 1 that will work.
With electronic 4x4 there will be a rotary dial below the radio and to the left ( 2H 4H 4L ) With manual 4x4 there will be a selector lever on the transmission hump also , when the vehicle is first started , there will be 4x4 and LOW RANGE lights on momentarily in the gauge cluster in order to check that the bulbs work
The 'kilogram' would work fine.
Lock your hubs and put the car in neutral, then push the 4X4 button, same thing with low range
All the way forward is 2wd next back 4wd high range, newtral next, 4x4 low range all the way back.
4x4 dash lights on a Dodge Durango don't work
