I'm assuming that model has a simple 4WD transfer case and not one with a front-to-rear differential. That means that there is no "slip" in the driveline. Generally you feel this when you try to turn at low speeds as a "binding" often accompanied by creaking or popping.
For a vehicle in normal condition, this causes no damage other than slipping the tires.
If the vehicle is damaged, however, the added stress of this may cause something to break but that's unusual in my experience. 4WD vehicles are designed to handle this, it's not a good practice because it causes difficulty in steering under some circumstances and hurts fuel-economy but should not cause any long-term damage to your driveline.
If the vehicle has a fancier transfer case, then there is slip allowed there and there is no issue at all. Often these vehicles say "Full Time 4WD" or similar.
