Timken SP550208 Wheel Bearing and Hub Assembly - Front

Timken SP550208 Front Hub Assembly

Timken SP550208 is a front wheel bearing and hub assembly built for driven applications that demand stable wheel support, accurate ABS signal performance, and consistent braking feel. It is a direct-fit option for select Ford F-150 and Lincoln Mark LT heavy-duty 7-stud front applications.

Key Features

• OE-developed testing used to control design, materials, and manufacturing process
• Low runout construction helps reduce noise and vibration
• Premium seals with reinforced outer case and ribbed rubber inner diameter
• Internal contamination exclusion system and vent holes help protect seal life
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes
• 100% tested ABS sensor for wheel speed monitoring
• Driven hub assembly with 45 splines, 7 wheel studs, and 4 flange bolt holes
• Bolt circle diameter: 150.00 mm (5.906 in); flange diameter: 190 mm (7.480 in)

Detailed Description

Built for front axle service, Timken SP550208 combines a wheel bearing and hub assembly in one unit for select 2005-2009 Ford F-150 and 2006-2008 Lincoln Mark LT heavy-duty 7-stud configurations. The hub uses precision bearing geometry and refined surface finishes to support load capacity, bearing life, and efficient operation, while low runout helps limit brake pulsation, noise, and vibration. Timken SP550208 is also engineered with an integrated ABS sensor that is fully tested for wheel speed monitoring, making it a practical replacement for vehicles that rely on accurate anti-lock braking input. This part cross-references SKF BR930459 for the same application.

What It Helps Address

• Front wheel noise from worn hub or bearing components
• Vibration or runout felt through the steering wheel or brake pedal
• ABS warning concerns related to wheel speed signal issues
• Uneven braking feel caused by hub instability
• Excess play or looseness at the front wheel assembly

Installation Notes and Fitment

Compatible With 2005 Ford F-150, front; 2006-2008 Ford F-150, front; 2006-2008 Lincoln Mark LT, front; and 2009 Ford F-150, front. Fitment notes include Heavy Duty - 7 Stud for 2005 and 2006-2008 F-150 applications, and Heavy Duty - 7 Stud - From 11/29/2004 for the 2005 F-150 listing. Verify spline count, bolt circle, pilot diameters, and ABS connector details against the original part before installation. Timken SP550208 is intended for driven front hub service on the listed vehicles.

Quality Assurance

Timken applies OE-developed testing to the design, materials, and manufacturing process of this hub bearing assembly. The result is a replacement part built around controlled fit, sealing, bearing geometry, and ABS sensor validation for consistent service performance.
