Detailed Description

Timken HA590390 is engineered for rear hub service on 2009-2010 Chevrolet Corvette, 2012-2013 Chevrolet Corvette, and 2009 Cadillac XLR. It is a driven wheel bearing and hub assembly with a 72.41 mm wheel pilot diameter, 81.08 mm hub pilot diameter, 145.5 mm flange diameter, and 42.45 mm flange offset. The design uses OE-developed testing methods to control materials, manufacturing processes, and performance consistency. For drivers searching for a rear wheel bearing and hub assembly for Chevrolet Corvette or Cadillac XLR, the HA590390 provides the dimensional accuracy needed for proper fit and wheel-speed signal reliability. This part cross-references SKF BR930757 for the same application.

Common Issues This Part Can Address

• Rear wheel bearing noise or growling
• Excess wheel play or looseness at the hub
• ABS warning light caused by wheel-speed sensor issues
• Brake pulsation or vibration related to hub runout
• Uneven wheel rotation or rough rear-end operation

Installation Notes and Tips

Verify spline count, flange dimensions, and rear-position fitment before installation. Clean the mounting surface thoroughly and inspect surrounding brake and axle components for wear before replacing the hub assembly. On 2012-2013 Chevrolet Corvette models, confirm FE1 Soft Ride or FE2 Ride and Handling suspension application before ordering. Proper torque procedures and sensor connector inspection are important for accurate ABS operation after installation.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test controls for design, materials, and process consistency. The bearing package uses precision internal geometry and refined surface finishes, while the seal design includes contamination exclusion features to support long-term performance.
