That's a start. (That site is good for really general info about recalls, as well.)

look on back of front diff.looks like windshield wiper motor

Didn't know there was a transferr case motor. I have a 91 and when it's cold out, I have to push my 4x4 button 3 or 4 time before it will engage. I hear the solenoid clicking, but it will not engage until it warms up a little. Could this be the motor, and have you found it yet???
thanks in advance for any help
