What It Helps Repair

• Front wheel bearing noise or rough rotation
• Excessive hub play or looseness
• Wheel mounting issues related to worn hub components
• Front-end vibration traced to hub and bearing wear
• Service needs on Ford F-250 Super Duty and F-350 Super Duty SRW front hubs

Installation Notes and Tips

Verify SRW configuration and model year before ordering, since fitment is limited to the listed Ford Super Duty applications. Confirm the 55-spline, 170 mm bolt circle, and flange dimensions against the original part before installation. Because the ABS sensor is not included and the unit is listed without ABS provisions, check the vehicle’s front hub setup and transfer any required external components from the original assembly if applicable.

Quality Assurance

Dorman replacement parts are engineered for specific vehicle applications and built to restore the original hub and bearing service function on the listed Ford trucks.
