You Definately have a Gear Broken in the Transfer Case. It is not Easy to Rebuild. I would find a Tranny Shop and see if they could rebuild it for you. Tranny shops here in OKLAHOMA Do.

My SUV is in 4 wheel drive. I am putting it in neutral and turning the knob to 2 wheel drive. However it will not go out of 4 wheel drive. I really need help, can you help me?


Pull the lever from 4HI to 2HI and you're good to go. It'll take a couple of seconds for the actuator on the front axle to disengage and maybe even some driving, its not a problem though. 4LO is a different story, I usually get up to about 3 mph, put the tranny in neutral, and then shift into 2HI, it makes less weird noises that way :-P Do it in one swift motion though.

2000 chevy suburban stuck in 4 lo anyone out that cant help


Put truck in Neutral while key in run position engine off or on (doesn't matter which). If it's pushbutton 4wd then try hitting 4low again. if that doesn't work some of the chevy trucks required you to press 4hi to get into 4high and then press 4hi again to get back to 2hi, unless yours has a 2hi button. In that case press 4hi to get into 4high and then press 2hi to get back to 2wd. either way you need to be in neutral to get out of 4lo. I have shift on the fly (Mechanical Shifter on floorboard for transfer case) on my 1990 Suburban and still have to put it in neutral to get out of 4lo. Good Luck.

4Hi won't switch back to 2Hi


First try hitting the 2HI when in nuetral. If that doesn't work put the vehicle in reverse and hit the 2HI switch and tap the brakes at the same time. Usual if you do this, when you put it into drive it will release.

02 dakota wont shift from 4hi to 2 hi


Try commanding the drive ranges while in netural cycling them. This may normalize the controller that senses the position from the encoder motor assembly. There maybe a procedure for that in a service manual.

You should be able to put in 4x4 while in drive less than 35mph. Mine had a switch to turn to engage or dis-engage.
