Detailed Description

Timken SP550202 is a direct-fit front hub bearing assembly for 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator models. Timken uses OE-developed testing and controlled manufacturing processes to maintain consistent dimensional accuracy, while the precision bearing profiles and enhanced surface finishes are intended to support load capacity, bearing life, and fuel efficiency. The reinforced seal design helps protect the bearing from contamination and supports reliable sealing in daily driving conditions. This part cross-references SKF BR930453 for the same application.

What It Helps Fix

• Wheel noise from a worn front hub bearing
• Steering or braking vibration caused by hub runout
• ABS warning concerns related to wheel-speed signal issues
• Loose or rough front wheel rotation
• Uneven braking feel from a deteriorated hub assembly

Installation Notes and Tips

Verify front axle application, bolt pattern, and pilot dimensions before installation. Clean the mounting surface thoroughly and inspect the knuckle, axle area, and brake components for wear or damage before fitting the new assembly. Confirm ABS connector routing and sensor alignment during installation on Ford Expedition and Lincoln Navigator front hub service.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures and controlled material and process standards. The ABS sensor is fully tested for wheel-speed monitoring, and the bearing design uses precision internal geometry and refined surface finishes to support consistent performance.
