Timken SP550201 Wheel Bearing and Hub Assembly - Front

Timken Hub Bearing Assembly for Front Applications

The Timken SP550201 wheel bearing and hub assembly is built for front driveline service on select Ford and Lincoln trucks and SUVs. It combines OE-developed testing, low runout, and precision bearing construction to support smoother operation, reduced noise, and stable braking performance.

Key Features

• Front wheel bearing and hub assembly for driven applications
• 33-spline design with 5 wheel studs and 3 flange bolt holes
• Low runout construction helps reduce noise and vibration
• Premium seals use reinforced and contamination-resistant features for improved sealing
• Precision bearing profiles and uniform internal geometry support load capacity and bearing life
• ABS sensor is 100% tested for wheel speed monitoring

Detailed Description

Timken SP550201 is a front wheel bearing and hub assembly engineered for 1997-1999 Ford Expedition and 1998-2000 Lincoln Navigator models with M12 bolts. This Timken hub assembly uses OE-developed validation methods to control design, materials, and manufacturing processes, helping deliver consistent performance in demanding front-end service. The bearing design uses enhanced surface finishes and precision internal geometry to support load handling and fuel efficiency, while the seal design helps protect against contamination and installation damage. If you are replacing a worn front hub on a Ford Expedition or Lincoln Navigator, SP550201 provides a direct-fit service part for the specified applications.

This part cross-references MOOG Hub Assemblies 515004 and SKF BR930208 for the same application.

Common Problems This Part Can Address

• Front wheel bearing noise or growling
• Excessive wheel play or looseness at the hub
• ABS wheel speed signal faults related to the hub assembly
• Brake vibration or inconsistent braking feel from hub runout
• Seal wear that allows contamination into the bearing area

Installation Notes and Tips

Verify front position, bolt pattern, spline count, and M12 bolt application before installation. Confirm the vehicle is a 1997-1999 Ford Expedition or 1998-2000 Lincoln Navigator with the listed front fitment. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear before installing the new hub assembly.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The SP550201 also includes a 100% tested ABS sensor to support accurate wheel speed monitoring for anti-lock braking systems.
