When you watch a vehicle gliding down the street, one of the first things you notice is the wheels moving seemingly effortlessly, but what you may not think about is the construction that makes this movement possible and ensures that all of the wheels move at the appropriate rate for the circumstances. On your Jeep, your Dana 30 front axle handles this responsibility. The axle is an assembly featuring a housing and a shaft. It is through this shaft that the torque transfers from the engine and transmission into the wheels so that they can move. The Dana style is predominantly an independent suspension system, meaning that each wheel has independent support and can respond to the bumps and changes in the road by moving vertically. This creates a smoother ride that reduces wear and tear on your vehicle. To further protect your tires and transmission, a Dana 30 locker prevents your wheels from rotating at different rates except in certain circumstances, such as when turning.
