no more hard questions exits on cars than SWAPs

1. it has to fit bolt on
2. must fit both PROP shafts and splines and lengths
3. and not make the PCM angry. wiring mods?

q1 is did dodge even offer it as an option
why not ask on a real Durango forum

google found that in 1 second flat.

I doubt if the encoder motor is causing the transfer case to stay in low 4WD. It is more likely a problem inside the transfer case.

look at the transfer case shifter knob, if it has 2h, 4h, 4pt, n, 4l, you have a 242.

This will set C (chassis) codes. You need to start there as the encoder motor (what performs the electronic shifting for the T-case drive modes {4-hi,2-hi-4lo}) will set codes that will enable you to quickly confirm if the encoder motor is indeed the problem. This is very common given the age of the vehicle.

It means your 4 wheel drive system needs to be serviced or is detecting a malfunction.

It is probably the encoder motor attached to the transfere case. look under the vehicle to see if there is signs of corrosion between the encoder motor and transfere case.

ok let me tell you my problem 200 bravada acts like stuck 4wd when slow turns parking lot this is whati did and fixed it first changed fluid tract 2 / 3 times no change replaced module in right kick pnl no change replaced encoder motor no change replaced transfer case with a low mile case no change took old case apart to see what makes it tick i found out that a spring is in there to push the encoder motor back into 2wd and it was not doing its job knowing this is a common problem i took the spring out and streched it and shimed it till it pushed the encoder motor back to 2 wheel drive instaled that spring and shim into the used transfer case that was in the truck wala problem gone the spring is very easy to get at on the bottom of the transfer case is a nut remove it and the spring will come out this is only true till 2001 then the case changed on 02

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

How may buttons for the 4X4 two , three , or four ? Do the lights flash ? Any messages - service four wheel drive system ? Which transfer case does it have ?

Transfer Case - NVG 246-NP8 (Two Speed Automatic)
The transfer case shift control module uses the VIN information for calculations that are required for the different calibrations used based on axle ratio, transmission, tire size, and engine. The system does not know which calibration to use without this information.
Transfer Case Encoder Motor
The transfer case encoder motor consists of a permanent magnet (PM) DC motor and gear reduction assembly. It is located on the left hand side (drivers side) of the transfer case. When activated it turns the sector shaft of the transfer case (clockwise or counter clockwise) to shift the transfer case. The encoder motor is controlled with a pulse width modulated (PWM) circuit within the transfer case shift control module. This circuit consists of a driver on both the Motor Feed A and Motor Feed B circuits. The encoder motor is bi-directional to allow the motor to shift the transfer case from 2HI or 4HI to NEUTRAL and 4LO positions.
Transfer Case Encoder
The encoder is mounted to the transfer case encoder motor assembly and is replaced as an assembly. The encoder converts the sector shaft position (representing a mode or range) into electrical signals inputs to the transfer case shift control module. The module can detect what position the transfer case is in by monitoring the 4 encoder channels (P, A, B, and C). These inputs translates into AUTO 4WD, 2H, 4H, NEUTRAL, and 4L or in transition between gears.
Transfer Case Motor Lock
The transfer case motor lock is used to provide a 2H, 4H, and 4L lock-up feature. When the lock circuit is energized, the transfer case encoder motor is allowed to turn. When the transfer case is placed 2H, 4H, or 4L the motor lock circuit has no power provided to it and the lock is applied. This assures that the transfer case remains in the current gear position. When AUTO 4WD is selected the motor lock remains applied until an adaptive mode (torque is applied to the front propshaft) is required. During an adaptive mode the motor lock circuit is energized and the motor lock is released, enabling the encoder motor to turn and apply torque to the front propshaft.


SERVICE indicator (4WD/AWD) Lamp
The SERVICE indicator (4WD/AWD) lamp is an integral part of the cluster and cannot be serviced separately. This lamp is used to inform the driver of the vehicle of malfunctions within the automatic transfer case (ATC) system. The SERVICE indicator (4WD/AWD) lamp is controlled by the transfer case shift control module via a Class 2 message or by a Sevice Indicator Control Circuit.

The first thing to do before assuming it's a loose wire would be to have it checked for codes , auto zone , advance etc... can not check this codes .
