Detailed Description

Timken HA590071 is engineered as a direct-fit front hub assembly for vehicles that rely on a driven hub design. It uses OE-developed testing methods to control the design, materials, and manufacturing process, helping maintain consistent performance in everyday driving. The assembly features precision internal geometry, a 64.97 mm wheel pilot diameter, a 65.45 mm brake pilot diameter, a 90.00 mm hub pilot diameter, and a 39.00 mm flange offset for proper fitment on the specified applications.

This part cross-references MOOG Hub Assemblies 513215 and SKF BR930314 for the same application. For shoppers searching for a 2004-2007 Chevrolet Malibu front wheel bearing hub assembly or a 2005-2007 Pontiac G6 front hub assembly, Timken HA590071 provides the fitment and dimensional details needed for a correct replacement. The ABS sensor is tested to monitor wheel speed for anti-lock braking system operation.

What It Helps Fix

• Wheel bearing noise from a worn front hub assembly
• Excess wheel play or looseness at the hub
• ABS warning light concerns related to wheel speed signal issues
• Brake pulsation or vibration linked to hub runout
• Uneven rolling resistance caused by bearing wear

Installation Notes and Tips

Confirm the vehicle’s front application, spline count, bolt pattern, and pilot diameters before installation. Clean the mounting surface thoroughly and inspect the knuckle, axle interface, and brake components for wear or damage that could affect hub alignment. Verify ABS connector routing and sensor seating during installation to avoid signal issues after replacement.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed testing and controlled production processes. Premium seals, precision bearing profiles, and tested ABS sensing support consistent performance, reduced contamination risk, and long service life in the specified applications.
