Detailed Description

Timken HA590286K is engineered for front-wheel applications that demand stable hub support, accurate wheel speed signal performance, and consistent bearing operation. The assembly uses precision bearing profiles and controlled internal geometry to help maintain load capacity and bearing life, while the sealed design helps protect internal components from contamination. This part cross-references SKF BR930286 and BR930567K for the same application.

Compatible With 2001-2012 Ford Escape, front; 2001-2006 Mazda Tribute, front; 2008-2011 Mazda Tribute, front; and 2005-2011 Mercury Mariner, front. For shoppers searching for a front wheel bearing hub assembly for Ford Escape, Mazda Tribute, or Mercury Mariner models, Timken HA590286K matches the listed OE-style fitment and wheel-end dimensions.

What It Helps Address

• Wheel bearing noise from worn hub components
• Front-end vibration caused by excessive hub runout
• ABS warning concerns related to wheel speed signal issues
• Uneven braking feel linked to hub or bearing wear
• Loose or rough wheel rotation at the front axle

Installation Notes and Tips

Verify spline count, bolt circle, wheel pilot diameter, and brake pilot diameter before installation. Confirm front-position fitment for the exact year and model, especially on Ford Escape, Mazda Tribute, and Mercury Mariner vehicles. Inspect the mating surfaces, axle splines, and ABS connector condition during replacement to help ensure proper seating and signal operation.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures and controlled design, material, and process standards. The ABS sensor is 100% tested, and the bearing and seal design is built to support consistent performance in front-wheel service.
