Why does the front wheels turn so hard when jacked up?

When the front wheels of a vehicle are jacked up, the weight of the vehicle is removed from the suspension and steering components. This can lead to reduced friction and resistance in the steering system, making it easier for the wheels to turn. Additionally, if the steering system is not under load, it may feel like the wheels turn more freely or "harder" because there is no weight pressing down on them to provide resistance. However, if there is excessive difficulty turning the wheels even when jacked up, it may indicate issues with the steering mechanism or suspension components.
