Product Details and Specifications

The MPA Electrical WH590431 wheel bearing and hub assembly is specifically designed for compatibility with Mazda vehicles, providing a precise fit for improved driveline stability. The trapezoid flange shape and 4 bolt hole configuration allow for secure mounting, while the 4 wheel studs sized M12 x 1.5 ensure proper wheel attachment.
