Detailed Description

Timken SP450201 uses OE-developed testing methods to control the design, materials, and manufacturing process of the hub bearing assembly. The result is a front hub assembly with precision bearing profiles, uniform internal geometry, and enhanced surface finishes that support load capacity, bearing life, and fuel efficiency. Low runout helps reduce noise and vibration while supporting more consistent braking performance. Premium seals add contamination exclusion features and reinforced construction to help maintain sealing performance during installation and service. This part cross-references SKF BR930343 for the same application.

What It Helps Solve

• Front wheel bearing noise
• Wheel vibration from excessive runout
• ABS wheel-speed signal faults
• Uneven braking feel related to hub wear
• Loose or worn hub support at the front axle

Installation Notes and Tips
