* 4WD won't work: The front axle will be completely disengaged.
* ABS may malfunction: Some ABS systems rely on the front driveshaft's rotation for proper function. It might throw a code or fail to work correctly.
* Speedometer inaccuracy: The speedometer on some models may be inaccurate, relying on the front driveshaft for input.
* Possible binding issues: With a transfer case in neutral, it might be better to also remove the front axle disconnect (if present) to prevent binding in the drivetrain.
Driving a Jeep Wrangler without the front driveshaft is perfectly possible *in 2WD only*, but it limits functionality. If you're taking it off for repair or replacement, that's fine. Just remember to re-install it to regain 4WD capability.
