Axle Mechanical Assembly - 5.75
SAF-Holland

The 02500557700Z Axle Mechanical Assembly in 5.75 inch size is a complete workpiece that forms the core mechanical connection between wheel hubs and suspension components. This assembly emphasizes precision alignment and rigidity to ensure consistent hub position, stable steering geometry, and reliable torque transfer under heavy loads. It supports the mounting of bearings, seals, and drums or rotors while providing the correct interface for other drive-line components. Material selection and machining tolerances are chosen to resist wear, reduce noise, and extend service life in demanding highway or off-road conditions. Proper installation requires careful seating, correct fastener torque, and verification of runout at the hub to prevent vibration and uneven wear. Regular inspection for signs of wear or misalignment will help maintain reliable performance over the vehicle’s lifetime. Source One Parts Center.
