Timken 515031 Wheel Bearing and Hub Assembly - Front

Timken 515031 Front Hub Bearing Assembly

Timken 515031 is a front wheel bearing and hub assembly built for driven applications that need stable wheel support, accurate ABS wheel-speed monitoring, and consistent braking feel. It is a direct-fit option for 2000-2002 Ford Expedition and 2000-2002 Lincoln Navigator front applications with M14 bolts.

Key Features

• OE-developed testing used to control design, materials, and manufacturing process
• Low runout construction to reduce noise and vibration
• Premium seals with reinforced outer case, ribbed inner diameter, contamination exclusion features, and vent holes
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes
• 100% tested ABS sensor for wheel-speed monitoring
• Driven hub assembly for front axle applications

Detailed Product Overview

This Timken hub bearing assembly is engineered around the demands of full-size SUV front driveline service. The assembly uses premium bearing surfaces and controlled internal geometry to support load capacity, improve bearing life, and maintain smooth wheel rotation. Its low-runout design helps reduce vibration and noise while supporting more consistent braking performance. Timken 515031 also includes an ABS sensor that is tested to monitor wheel speed for anti-lock braking systems, making it a practical replacement for vehicles that rely on integrated wheel-speed input.

Fitment includes 2000-2002 Ford Expedition, front, M14 bolts and 2000-2002 Lincoln Navigator, front, M14 bolts. This part cross-references SKF BR930236 for the same application.

What It Helps Address

• Wheel bearing noise from worn or rough hub components
• Front-end vibration caused by excessive hub runout
• ABS warning lights related to wheel-speed sensor issues
• Uneven braking feel linked to hub instability
• Reduced wheel support from bearing wear in driven front applications

Installation Notes and Tips

Confirm front axle fitment, bolt pattern, and M14 bolt application before installation. Inspect the knuckle, axle splines, and mounting surfaces for wear or corrosion that could affect hub seating. Clean the mating surfaces thoroughly and torque fasteners to the vehicle manufacturer’s specification to help maintain proper bearing preload and ABS sensor performance.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The design emphasizes seal durability, bearing surface quality, and ABS sensor verification to support consistent performance in service.
