2005 dodge dakota 4x4 transfer case stuck in 4 w low

hi i have a problem with my 2003 dodge Dakota i have it in 2h but it switches into fwd on its own can anyone help me with this problem

1. • 1 Start your Dodge truck's engine.
     
   • 2 Turn the electronic transfer case from "2WD" to "4WD Lock" to engage the high range 4WD, if the dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" to "4H." The electronic transfer case is located on the instrument panel and is marked with "2WD," "4WD Lock" and 4WD Low." The lever-equipped transfer case is located to the right of your leg and is marked with "2H," "4H" and "4L."
     
   • 3 Shift the transmission into "Neutral" while the vehicle is either stopped or rolling at 2 to 3 mph to begin engaging in the low range 4WD. Turn the electronic transfer case to "4WD Low," if the Dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" or "4H" to "4L."
     
   Tips & Warnings
   • Indicator lights will come on and alert you that your vehicle is in either the high or low range of 4WD.
     
   • Do not engage in the low range of 4WD drive if the transmission is in gear; you must shift to "Neutral" first.
     
   • Many Dodge trucks allow you to shift from 2-wheel drive to the high range of 4WD at up to 55 mph--consult your truck's manual to ensure that this is possible. Do not exceed 55 mph while engaged in the high range of 4WD. Do not exceed 25 mph while engaged in the low range of 4WD.
     
   • Do not engage in 4WD unless you are on slipper or rocky roads.
     

That maybe the case however I would check to make sure the linkage from the 4wd shifter did not pop out from the transfer case first.

you will need to replace the transfer case electric motor on the side of the transfer case

A Dodge Dakota with 4-wheel steer? Do you happen to mean 4-wheel drive?

If so, you should not operate the vehicle in 4-wheel drive when you are traveling on a hard, high-traction surface. When in 4x4, the transfer case connects the front and rear axles, and does not allow for differentiation of wheel speeds necessary when turning. This is compensated for when driving over low-traction terrain because the tires slip easier.

Basically, the jerking, bucking and locking of the truck is due to the binding. This will eventually lead to damage in the driveline. If the roadway isn't covered in snow, there is no need for the 4 wheel drive to be engaged.

My 2005 Serria 4x4 truck will not work in 4 wheel drive high or low, but my Auto 4 wheel will work. Is there something wrong in the transfer case with electrical or mechanical?

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

U MUST remove the remove the drive shaft or u will damage the trans, this is true of all modern cars and trucks, have been doing this 35 years and am 100% sure on this.

No this trans would not fit as it has the wrong output shaft for the transfer case.

check the rear differential as well as the transfer case...you may have broken something in both of them...i have seen it happen...since 4low uses a different gear it is possible for it to move in low and not 4 high
