• 26-spline design with a 5-lug, 4.5-inch bolt circle
• Wheel pilot diameter: 2.358 in. / 59.9 mm
• Brake pilot diameter: 2.433 in. / 61.8 mm
• Flange diameter: 139 mm / 5.472 in.
• Low runout construction helps reduce noise and vibration
• Premium seals use reinforced and contamination-resistant features for sealing performance
• ABS sensor is 100% tested for wheel-speed monitoring

Detailed Description

Timken HA590303K is a front wheel bearing and hub assembly engineered for 1992-2003 Toyota Camry and 1999-2003 Toyota Solara models. The assembly uses precision-profile bearings with uniform internal geometry and enhanced surface finishes to support load capacity, bearing life, and efficient operation. Low runout helps maintain smoother braking response and reduced road noise, while the integrated ABS sensor supports accurate wheel-speed input for anti-lock braking systems. This part cross-references SKF BR930303K for the same application.

What It Helps Fix

• Front-end wheel noise from a worn hub bearing
• Steering vibration caused by excessive hub runout
• ABS warning light concerns related to wheel-speed signal issues
• Brake pulsation or inconsistent braking feel tied to hub wear
• Loose or rough wheel rotation at the front axle

Installation Notes and Tips

Fits 1992-2003 Toyota Camry, front. Fits 1999-2003 Toyota Solara, front. Confirm the 5-lug, 4.5-inch bolt circle, 26-spline drive configuration, and pilot diameters before installation. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear so the new hub assembly can seat correctly.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes to support consistent hub bearing performance. The ABS sensor is fully tested for wheel-speed monitoring, and the seal design is built to support contamination resistance and longer service life.
