TurnI get a rumble when turning backing up or going forward for the first 20 feet

park it...put it back into 2wd...slowly drive forward about 20 feet...it should reset back into 2wd...let me know if it doesnt please and we can go to the next step. Good luck

go to the magicmechanic website and send him this--hes the best there is and will rply

Isn't this the wire that provides power TO the ICM not from it? if so trace that wire back and see where it does.. look for a short or open.

Are the front hubs still locked in?

If you have manually locking front hubs, you probably have a bit of binding in the drive train due to the front wheels being locked to the drive system

After unlocking the hubs, back up about 20 feet, then back forward about 20 feet.....see then if the transfer case can then be disengaged. You MAY need to just yank on the transfer case shifter while the vehicle is moving (slowly of course).....

I had an older ford pickup which did the same thing.....disengaging the hubs and just yanking the shifter had disengaged the 4 wheel drive then I was able to put it back into 2wh high.

This happens now and again on 4X4's. You must not continue to operate it on normal "dry" surfaces until you disengage these hubs. Permanent damage will result. First thing to do is make sure you are on wet, loose gravel, sand, dirt, etc. Switch transfer case back to 4Low. With steering straight move a little forward and without hitting the brake slip in neutral allowing truck to come to rest by itself. Switch Transfer case to next position, I assume 4low. Place in drive and drive forward and backward until you feel it come out of 4 low. You don't have to drive it crazy back and forth, just 5MPH normal back and forth maybe 20 feet forward and 20 feet backward. It's good to allow the truck to stop by itself allowing the hubs to spin freely then placing in reverse doing the same. Apply brake, repeat until unlocked. You may find that if it is not unlocking, try to push lever back into 4low, power on, the release accelerator, switch to 4high all the while it is drifting and gently power on again. If you drive on solid surfaces ignoring the driveline, you will bind the axles and destroy some element of your drive line...The weakest points first. Hope this help and do not forget to rate this high if it helped you.

never shift on the fly. its just not a good idea. try shifting while at a stop. then go forward 20 feet and then back up 20 feet repeat this a few times. do this also when you go to disengage . there is a solenoid that is pumpkin of the front axle this may be bad or weak. a easy fix cheap too for a 4wd fix

With all due respect, what the H___ are you doing driving in 2 Feet of SNOW? The rumbling noise you hear is most likely caused from Snow being impacted in the CV Joints, Wheel Wells and anywhere else from freezing in place after driving in the "Deep Snow". The solution is to have the care raised on a Hoist and Pressure Washed to remove all Snow and Ice from the the entire Bottom Side of the Vehicle. It then should be allowed to dry thoroughly in that building before being driven. Additionally, if any noises occur upon exiting that facility turn around and have it repaired before it costs you untold thousands of dollars to repair.

Next time you have "DEEP SNOW" wait until the Roads have been cleared, salted or sanded and are back down to pavement before driving on them.

You can move the drivers seat back by turning on the power, getting in the seat and position your feet firmly on the fron flor with your back firmly against he seatback, and then engage the switch pushing back - while pushing like hell with your feet. You can actually hear the seat drive shaft turning while the seat moves back. The principle should be the same for moving forward, but pressure would have to be aplide to the back of the seat.

With the selector in 2WD, attempt to slowly move the car forward (drive)and backward (reverse) in an area of 15 or 20 feet. That should release the 4WD gearing engagement.

Good luck

You probably have a bad wheel bearing or bad tire on left front. when making right turn left front wheel wil spin faster than right making noise louder.
