Not all axles are created equal. Quality Ten Factory front Jeep JK 44 hardened axle shafts are beefy and strong. Ten Factory includes a 10-year free replacement warranty with all their axle shafts. Note that the Ten Factory axles use the large OE Jeep JK Spicer 5004891 U-joints that have improved seals and are much stronger than earlier, smaller 5-760X joints. Some say that smaller joints are stronger because there’s less leverage on the cross. They’re mistaken. Make sure the axles you purchase use the larger, OE 5004891 JK U-joints. West Coast Differentials stocks the factory U-joints and had them to us next day.
