Description
The Axiom Supply AX104A Front Wheel Bearing & Hub Assembly is engineered as a heavy-duty replacement for the factory front wheel hub on 2023–2026 Ford F-250 and F-350 Super Duty 4WD SRW trucks.
Developed with Axiom Supply's proprietary bearing and hub structure, this assembly is designed to reduce hub-face deflection under load, helping provide tighter steering response, improved braking stability, and increased durability under demanding conditions.
Heavy towing, oversized tires, lifted suspension systems, rough terrain, and commercial use can place substantial loads on the front wheel-end assembly. AX104A combines precision bearing components, premium grease, high-strength wheel studs, and an integrated ABS sensor into a complete bolt-in assembly designed for long-term reliability.
The assembly fits either the driver or passenger side front position and is designed as a direct replacement for the factory SRW 4WD hub configuration.
