I am familiar with conventional 4x4 manual transmission and transfer case operation. Easy, clutch, stick, low or high range. Manual hubs. Easy. My newish to me vehicle is another matter. I need to understand what and why before I go any further or $$$. Purchased with 144,000 miles. The 4x4 worked. 3 Positions Auto High Low. In Low the front end would bind when turning in a paved parking lot, with the Low light on just as it should. Somewhere along some miles, the system quit. The indicator lights do not light, and any apparent 4x4 function is gone. The one time I needed, really needed my front axle, no dice. Stopped on a steep uphill with both rear spinning making clouds of dust, no, zero front traction. No buttons able to do anything.
So.... if the system defaults to 4x4 with 75% rear, and 25% front, why doesn't it bind at low speed on paved surface ?
And, what specifically would entirely disconnect the front axle ? Is this a function of the Traction control module, AKA 4x4 computer found behind the glove box ?
If the answer is a cpu, are the rebuilt ones a safe purchase and does the Vehicle CPU have to be integrated by a dealer or other effort ?
Thanks !!
