Timken HA590132 Wheel Bearing and Hub Assembly - Front

Timken HA590132 Hub Assembly Overview

Timken HA590132 is a front wheel bearing and hub assembly for select 1999 Ford F-250 Super Duty and Ford F-350 Super Duty models with single rear wheels and coarse thread studs through 3/21/1999. Built for driven front applications, it is engineered to support stable wheel rotation, consistent braking feel, and reduced noise and vibration.

Key Features

• Front wheel bearing and hub assembly for driven axle applications
• 55-spline design with 4 flange bolt holes
• 8 wheel studs and a 6.693 in. bolt circle diameter
• Low runout design to reduce noise and vibration
• Premium seals with reinforced construction and contamination control features
• Precision-profile bearings with enhanced surface finishes for load support and bearing life
• ABS sensor tested for wheel-speed monitoring in anti-lock braking systems

Detailed Product Description

Timken HA590132 is built using OE-developed testing methods that guide the design, materials, and manufacturing process of the hub bearing assembly. The result is a front hub unit with controlled runout, precision internal geometry, and bearing surfaces engineered for consistent performance in demanding truck use. This part cross-references SKF BR930427 for the same application.

For 1999 Ford F-250 Super Duty and 1999 Ford F-350 Super Duty front axle service, this assembly is specified for single rear wheel trucks with coarse thread studs through 3/21/1999. The hub features a 124.97 mm wheel pilot diameter, 129.01 mm brake pilot diameter, 113.90 mm hub pilot diameter, 51.50 mm flange offset, and 203.00 mm flange diameter. Timken HA590132 is a direct-fit service part for restoring proper wheel support and ABS wheel-speed signal function.

What This Part Helps Address

• Front wheel bearing noise on Ford Super Duty trucks
• Wheel vibration caused by excessive hub runout
• Uneven braking feel related to worn hub components
• ABS warning concerns tied to wheel-speed sensor issues
• Loose or worn front hub support on driven axle applications

Installation Notes

Verify the vehicle is a 1999 Ford F-250 Super Duty or Ford F-350 Super Duty, front position, with single rear wheels and coarse thread studs through 3/21/1999 before ordering. Confirm spline count, bolt circle, pilot diameters, and ABS configuration against the original hub assembly. Proper torque procedures and clean mounting surfaces are important for correct hub seating and brake performance.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test standards and 100% tested ABS sensors to support wheel-speed monitoring. The design emphasizes sealing, bearing geometry, and surface finish control to help maintain consistent operation in service.
