Cant get it out of 4wheel drive i switched it over to 4wheel drive without putting it into neutral

Does it shift to 4wd high range ? If so then shift to 2wd . What is going on here is the transfer case motor is stopping due to the motor position sensor has gone bad which means that you replace the transfer case motor assembly. But if you wish to make it a 2wd for awhile then remove motor and manually turn shaft . This can be done by raising and supporting rear axle truck in park remove motor turn shaft slowly with pliers and rotating the play in drive shaft. There are stamped markings on back of case showing gear positions..

Could be your neutral safety switch is bad.

4 wheel neutral vehicle will not move that for towing or moving around --put in 2wh --4hi or if have 4low transfer case has to be in a setting to move

it has to be running and in neutral to engauge the 4x4. shift to neutral,then push the 4x4 option that you want. 4wheel high you can use almost any sensible speed.4wheel low is only for low speed 15 to 20mph is best for 4wheel low,otherwise will damage engine or transfer case. when you take it out of 4x4 it has to be in neutral also. thank you for choosing fixya.com

the vacuum lines run to the hubs behind the brake rotors on the front wheels

Try disconnecting the battery for a few minutes, that might get you out of trouble for now. There are some common problems with these 4wd systems. Most common is the mode position sensor on the encoder motor. Sometimes it can be the switch on the dash. Fact of the matter is I can't tell you what is wrong without using a scantool to retrieve the fault codes from the computer controlling the 4wd.

Have you tried putting the vehicle in neutral and than selecting it into 2 wheel drive? Try driving it in reverse and froward a couple of times and than selecting neutral before selecting 2 wheel drive

replace u-joints

this is common on these trucks just put your witch in 2 wheel and go ahead and drive it will let loos when it sees the correct secquence and drive a little and shift to netural.
just neve do it from high to low range

Put the transmission in neutral, emergency brake off, foot off the brake pedal, now try shifting out of 4 wheel drive low. If that doesn't work, drive forward, and again do the above, trans. in neutral, roll to a stop, foot off brake, try to disengage. What you're probably experiencing is called drive shaft 'wind up', and it is very difficult to disengage, but do the above and it should shift out of 4 low. countrycurt0
