Detailed Description

Timken HA590002 is a rear wheel bearing hub assembly engineered for driven rear applications on the Pontiac Vibe and Toyota Matrix. The assembly uses a 5-stud wheel mounting pattern, 4 flange bolt holes, a 3.928-inch bolt circle diameter, and a 5.315-inch flange diameter to match the specified wheel-end geometry. Timken’s manufacturing process emphasizes controlled runout, precision bearing surfaces, and seal integrity to help maintain smooth operation under everyday driving loads. This part number, HA590002, is a direct-fit wheel bearing and hub assembly for 2003-2006 Pontiac Vibe, rear, and 2003-2006 Toyota Matrix, rear.

What It Helps Address

• Wheel bearing noise from worn or rough hub components
• Vibration or looseness at the rear wheel end
• ABS warning concerns related to wheel-speed signal issues
• Uneven braking feel caused by hub runout or bearing wear
• Contamination-related bearing deterioration from failed seals

Installation Notes and Tips

Verify rear fitment by year, make, and model before installation. Confirm spline count, bolt pattern, flange dimensions, and ABS sensor configuration against the original part. Clean the mounting surface thoroughly and inspect adjacent brake and suspension components for wear before installing HA590002. For 2003-2006 Pontiac Vibe and 2003-2006 Toyota Matrix rear applications, follow factory torque specifications and service procedures.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The ABS sensor is 100% tested, and the bearing and seal design are built to support consistent wheel-end performance in service.
