Timken HA590394 Wheel Bearing and Hub Assembly - Front or Rear

Timken HA590394 Wheel Bearing Hub Assembly

Timken HA590394 is a front wheel bearing and hub assembly engineered for BMW driveline and axle applications that demand stable wheel support, low noise, and consistent ABS signal performance. It is built for non-driven front positions and is a direct replacement for select BMW X3, X4, 5 Series GT xDrive, 7 Series xDrive, and Gran Coupe models.

Key Features

• OE-developed testing is used to control design, materials, and manufacturing process consistency.
• Low runout helps reduce wheel-end noise and vibration while supporting braking performance.
• Premium seals use a reinforced outer case, ribbed rubber inner diameter, contamination exclusion features, and vent holes to improve sealing and durability.
• Precision-profile bearings with uniform internal geometry and enhanced surface finishes support load capacity and bearing life.
• ABS sensor output is 100% tested to monitor wheel speed for anti-lock braking systems.
• Non-driven hub assembly for front axle service on select BMW applications.

Detailed Description

This Timken wheel bearing and hub assembly is built around the needs of BMW front-end service, where hub accuracy, seal integrity, and wheel-speed signal quality matter. The HA590394 uses precision bearing construction and controlled runout to help maintain smooth rotation, reduce vibration, and support efficient operation. For BMW X3, BMW X4, and BMW 640i xDrive Gran Coupe or 650i xDrive Gran Coupe front axle repairs, this hub assembly provides a direct-fit replacement option that aligns with OE-style engineering expectations. This part cross-references SKF BR930929K and 513391 for the same application.

What It Helps Fix

• Wheel bearing noise from the front hub area
• Steering wheel or chassis vibration related to hub runout
• ABS warning lights caused by wheel speed signal issues
• Uneven braking feel linked to worn hub bearing components
• Excessive play or rough rotation at the wheel end

Installation Notes and Tips

Verify front axle fitment by year, model, and drivetrain before installation. Inspect the knuckle, axle interface, and mating surfaces for wear or contamination, and confirm the ABS connector and sensor routing match the vehicle configuration. Proper torque procedures and clean mounting surfaces are important for maintaining hub alignment and sensor performance.
