Spicer Front Hub Unit Bearing to Steering Knuckle Mounting Bolt Kit for Jeep Wrangler, Cherokee & Grand Cherokee (Set of 6, Both Sides)

Eliminate unsafe front-end hardware fatigue, ensure absolute torque retention on your wheel hub assemblies, and maintain factory-spec structural security with this genuine Spicer Hub Bearing to Steering Knuckle Mounting Bolt Kit. Specifically packaged as a complete, 6-piece dual-side hardware overhaul for classic Jeep Wrangler, Cherokee, and Grand Cherokee models, this high-tensile fastener set replaces stretched, rusted, or rounded-off factory hub bolts.

On vintage Jeep open-knuckle Dana 30 or Dana 44 front axles, the wheel hub unit bearings are clamped tightly to the steering knuckles by a pattern of three specialized 12-point bolts per side. These fasteners endure massive shear stress, continuous chassis vibration, and severe leverage forces from cornering loads, heavy braking, and the added weight of oversized off-road tires. Over high mileage, or during routine front-end teardowns for axle shaft, U-joint, or brake rotor service, the factory bolts naturally stretch, corrode, or suffer from damaged heads due to over-impacted tools. Reusing compromised or fatigue-stretched hardware risks clamping failure, which can lead to severe wheel hub looseness, catastrophic brake tracking issues, or hazardous hub-to-knuckle separation on the road or trail.

This original equipment manufacturer (OEM) hardware master pack includes 6 premium-grade, heat-treated mounting bolts to fully service both the driver and passenger side steering knuckles simultaneously. Sourcing genuine Spicer components guarantees the exact factory thread pitch, thread-locking compound properties, and specialized heavy-duty flanged 12-point head geometry engineered to survive rigorous daily commuting and demanding off-road conditions.
