Lockers on a 2007 Jeep Rubicon are used when you encounter challenging off-road conditions, such as mud, snow, or rocky terrain. Engaging the lockers helps provide equal power to both wheels on an axle, improving traction and stability. It's typically recommended to use them in low-range gearing and at lower speeds to maximize their effectiveness and prevent damage. Avoid using lockers on high-traction surfaces, like pavement, as this can lead to drivetrain stress.
