Detailed Description

Timken SP450202 is engineered as a wheel bearing and hub assembly for front axle service on select 2003-2010 Ford Ranger, 2003-2009 Mazda B4000, 2003-2005 Ford Explorer Sport Trac, 2005 Mazda B3000, and 2003 Ford Explorer Sport models. The assembly uses precision bearing geometry and refined surface finishes to support load capacity, bearing life, and fuel efficiency, while the low-runout design helps limit vibration and brake noise. Timken SP450202 also includes an ABS sensor that is tested to monitor wheel speed for anti-lock braking system operation. This part cross-references SKF BR930452 for the same application.

What It Helps Fix

• Wheel bearing noise from the front hub area
• Steering wheel or chassis vibration related to hub runout
• ABS warning concerns tied to wheel-speed signal issues
• Brake pulsation or uneven braking feel linked to hub condition
• Front-end looseness caused by worn hub bearing components

Installation Notes and Tips

Confirm front-position fitment and verify the ABS round connector on 2010 Ford Ranger applications before installation. Match the hub dimensions, spline count, bolt circle, and pilot diameters to the original part before service. For best results, inspect the mating surfaces, axle interface, and brake components for wear or contamination during replacement.
