Tech Insight

This knuckle stud is responsible for securing the spindle or steering arm to the knuckle on Dana 60/44 front axles. A proper OE-grade stud is critical as insufficient clamping force can cause steering looseness, spindle movement, or premature component wear. Spicers D-Stud design provides the correct anti-rotation profile, ensuring the stud stays locked in place under steering load or off-road stress.
