AAM 9.25" Front Differential Ball Joint Kit

The Yukon Ball Joint Kit is designed as a direct replacement for AAM 9.25” front differentials, providing essential components for your vehicle's suspension system. This comprehensive kit includes two upper and two lower ball joints, along with all necessary small parts for a complete installation. Constructed for durability and longevity, the kit features a CNC-machined forged SAE 1045 carbon alloy steel housing. This material choice contributes to extended joint life under demanding conditions. The ball stud is engineered from hot-forged, induction heat-treated 4140 chromoly, offering exceptional strength and resistance to wear. Furthermore, the ball joints incorporate extrusion rolled threads, which are significantly stronger than traditional cut-thread construction, ensuring a more robust connection. This kit is backed by a lifetime warranty against manufacturing defects, reflecting Yukon Gear and Axle's commitment to quality. Owners should note that a break-in period of 300 to 500 miles may be experienced, during which memory steer might occur as the components settle in.
