Timken HA590187 Wheel Bearing and Hub Assembly - Front

Timken Front Wheel Hub Assembly

Timken HA590187 is a front wheel bearing and hub assembly built for driven applications that demand stable wheel support, accurate wheel speed signal performance, and consistent braking feel. It is a direct-fit option for select Volvo S60, V70, XC70, and S80 models.

Key Features

• OE-developed testing helps control design, materials, and manufacturing process
• Low runout helps reduce wheel-end noise and vibration
• Premium bearing profiles and uniform internal geometry support load capacity and bearing life
• Enhanced surface finishes help reduce friction and improve fuel efficiency
• Premium seal design helps resist contamination and improve sealing life
• ABS sensor is 100% tested for wheel speed monitoring
• 36-spline driven hub design with 5 wheel studs and 4 flange bolt holes
• Bolt circle diameter: 108.11 mm / 4.256 in; flange diameter: 135.62 mm / 5.339 in

Detailed Description

This Timken wheel bearing and hub assembly is engineered for front axle service on 2001-2009 Volvo S60, 2001-2007 Volvo V70, 2003-2007 Volvo XC70, and 1999-2006 Volvo S80 applications. Timken HA590187 uses precision bearing construction, a driven hub layout, and integrated ABS sensing to support accurate wheel-speed input for anti-lock braking systems. The hub pilot diameter measures 87.41 mm (3.441 in), with a wheel pilot diameter of 65.00 mm (2.559 in) and brake pilot diameter of 68.00 mm (2.677 in), helping match the original mounting geometry on the vehicle.

This part cross-references SKF BR930277 for the same application.

What It Helps Address

• Front wheel bearing noise or humming
• Wheel-end vibration or runout-related brake pulsation
• ABS warning light caused by wheel speed signal issues
• Loose or worn hub assembly feel at the front axle
• Reduced braking consistency from worn hub components

Installation Notes

Verify spline count, bolt circle diameter, flange offset, and pilot dimensions before installation. Clean the mounting surface thoroughly and inspect the knuckle, axle interface, and brake components for wear or damage. Because this assembly includes ABS sensing, confirm connector routing and sensor alignment during installation. For best results, follow the vehicle service procedure and torque specifications for the specific Volvo model.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test standards and controlled production methods. The bearing, seal, and ABS sensor features are built to support consistent performance in front-wheel applications such as Volvo S60, Volvo V70, Volvo XC70, and Volvo S80. Part number HA590187 is engineered to meet the dimensional and functional requirements of the listed fitments.
