Detailed Description

Built for OE-style fit and function, Timken HA590186 uses controlled design, materials, and manufacturing processes to support dependable wheel-end operation. The hub assembly’s low runout construction helps limit brake pulsation, road noise, and vibration, while the precision bearing geometry supports load carrying capacity and bearing life. Key dimensions include a 65.00 mm wheel pilot diameter, 70.00 mm brake pilot diameter, 90.00 mm hub pilot diameter, 39.00 mm flange offset, 137.00 mm flange diameter, and 110.00 mm bolt circle diameter. This part number is a direct match for drivers searching for a Timken HA590186 wheel bearing hub assembly for Saturn Sky or Pontiac Solstice service work.

What It Helps Address

• Wheel bearing noise from worn or rough internal bearing surfaces
• Steering wheel or chassis vibration caused by hub runout
• ABS warning concerns related to wheel speed signal issues
• Brake feel changes linked to hub instability at the wheel end
• Uneven wheel-end rotation or looseness on driven hub applications
