Fitment and Application Details

Compatible With 2008-2017 Buick Enclave, front and rear; 2009-2017 Chevrolet Traverse, front and rear; 2017 GMC Acadia Limited, front and rear; 2007-2016 GMC Acadia, front and rear; and 2007-2010 Saturn Outlook, front and rear.

How This Hub Assembly Helps

• Wheel noise from worn or rough hub bearings
• Vibration felt through the steering wheel or body
• ABS warning lights caused by wheel-speed signal issues
• Uneven braking feel related to hub runout
• Loose or unstable wheel support at the hub

Installation Notes

Verify spline count, bolt circle diameter, hub pilot diameter, and brake pilot diameter before installation. Confirm front or rear placement against the vehicle listing, and inspect the mating surfaces for corrosion or damage so the new hub seats evenly. For Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook applications, matching the OE-style dimensions is important for proper fit and ABS operation.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process of its hub bearing assemblies. The HA590227 uses premium seals with reinforced construction and contamination control features, plus precision-profile bearings with uniform internal geometry and enhanced surface finishes to support load capacity, bearing life, and fuel efficiency.
