Its precise wheel pilot diameters of 2.776 inches (70.51 mm) and brake pilot diameters of 3.226 inches (81.94 mm) ensure proper alignment of wheels and brake components, reducing vibration and wear. The hub pilot diameter of 3.350 inches (85.08 mm) centers the hub accurately on the axle, while the flange offset of 1.927 inches (48.95 mm) maintains correct wheel positioning relative to the suspension and steering geometry. This assembly is compatible with Ford Explorer, Lincoln Aviator, and Mercury Mountaineer models, providing a direct replacement for OEM parts.

Common Applications and Problem Resolution

• Replacement for worn or damaged wheel bearing and hub assemblies
• Eliminates wheel vibration and noise caused by bearing failure
• Restores proper wheel alignment and brake component fitment
• Addresses issues with uneven tire wear due to hub misalignment
• Supports driveline integrity on driven axle configurations

Installation Notes and Tips

When installing the Timken SP470200, ensure the axle spline count matches the 27-spline design for proper engagement. Verify the flange bolt hole pattern and bolt circle diameter (114.30 mm) align with the vehicle’s hub mounting surface. Use appropriate torque specifications for flange bolts and wheel studs to avoid premature wear. Inspect brake pilot diameters to confirm compatibility with existing brake rotors or drums. Proper hub centering using the 3.350-inch hub pilot diameter is critical to prevent vibration and ensure smooth operation.
