Detailed Product Description

VAICO V40-0540 is a wheel hub assembly for the front axle of the 2008-2009 Saturn Astra, covering both front right and front left positions. The hub uses an angular ball bearing and a three-point mounting design to match the specified OE-style installation geometry. The integrated magnetic sensor ring supports wheel speed sensing at the hub, which is important for vehicles equipped with electronic stability and anti-lock braking systems.

VAICO’s VAICO product line focuses on application-specific replacement parts for European and import driveline service, and this wheel hub follows that approach with OE reference alignment and fitment-specific dimensions. The V40-0540 part number should be verified against the vehicle’s original hub specification before ordering, especially when matching sensor-ring and bolt-pattern details.

This part cross-references SKF BR930533 and Timken HA590297 for the same application.

What This Wheel Hub Helps Address

• Front wheel bearing noise from a worn hub assembly
• Wheel play or looseness at the front axle
• ABS or wheel speed signal faults related to the hub sensor ring
• Uneven wheel rotation caused by bearing wear
• OE-matching replacement needs for Saturn Astra front hub service

Installation Notes and Tips

Confirm the vehicle’s OE number, bolt circle diameter, rim hole count, and sensor-ring specification before installation. This hub is listed for 2008-2009 Saturn Astra front right and front left positions, so position matching matters during service. Clean the mounting surface thoroughly and inspect related suspension and brake components for wear before fitting the new hub.

Use the V40-0540 part number during parts lookup to confirm the correct Saturn Astra front hub assembly. For best results, compare the removed unit to the replacement part before final assembly.
