* Loss of power to one or both axles: This is the most common problem. You might only have 2WD capability even if it's a 4WD truck, or you might have no drive at all.
* Severe damage to other drivetrain components: Driving with a broken transfer case can cause damage to the axles, differentials, and even the transmission. This will lead to far more expensive repairs.
* Loss of control: A broken transfer case can lead to unexpected shifting of power or a complete loss of power, making the vehicle difficult or impossible to control, especially in slippery conditions.
* Further damage to the transfer case: Continuing to drive with a broken transfer case will worsen the damage, making the repair even more costly.
In short, if your transfer case is broken, you should have it towed. Driving it risks causing further and more expensive damage, and it puts yourself and others at risk.
