* Potential Damage: The front differential will still be rotating with the front wheels. This will cause binding and significant wear on the front differential components, potentially leading to damage. This is especially true if you attempt to drive at any significant speed.
* Uneven Tire Wear: The turning radius difference between the front and rear axles will result in uneven tire wear, potentially accelerating tire wear on the front tires.
* Unpredictable Handling: The engaged, but disconnected, front differential can contribute to unpredictable handling, especially in slippery conditions.
To properly disable 4WD, you need to either:
* Engage a 2WD mode (if your vehicle has one): Many 4WD vehicles have a switch or shifter to select 2WD, disconnecting the front driveshaft electronically or mechanically. This is the correct and safe way to disable 4WD.
* Use a 4WD system with manual locking hubs: Some vehicles have manual locking hubs on the front wheels. Unlocking these hubs disconnects the front wheels from the driveshaft. This allows for 2WD operation without the issues mentioned above.
Removing the driveshaft is a temporary and potentially damaging workaround. It's crucial to use the intended method for switching between 4WD and 2WD in your specific vehicle. Consult your owner's manual for the correct procedure.
