Check the solenoid at the front axel. This is a rather common prob. First check that power is at the axel, got power, clean and put it back. Please do not even look at the tranfer case! At worst you may need to replace the axel solenoid! Frankster016

The ECM or TCM may be the culprit, its also possible that a ground wire is no longer grounded or partially grounded giving you the erratic speedometer.

Very well could be taht the Computer is not recieving the Shift codes Correctly. Just for an Easy Solution, Remove the ECM Fuse from the Fuse panel for 2 or 3 Minutes to Reset the Computer and let me know what you get.

It's most likely the "four wheel drive actuator" This is located on the front differential housing. It's cylindrical shaped and has a large hex (about
1-1/4") and two wires coming out of it. Usually they short out and blow the fuse but, I've also seen where they just quit working and sometimes they just get slow to work. The "actuator" has a heating element in it and it warms up, some sort gas, causing it to expand thus engaging the front wheels. In cold weather it may take a minute or so for it to engage, so put in four wheel drive and wait for a bit and see what happens.
