Detailed Product Description

The MPA Electrical WH512401 wheel bearing and hub assembly is designed specifically for vehicles such as the Toyota 86, GR86, and FR-S, as well as Subaru models including the BRZ, Crosstrek, Forester, Impreza, Legacy, Outback, WRX, and WRX STI, plus select Scion models. This assembly features a 27-spline interface that ensures a secure connection to the drivetrain, while the included rectangular flange with four bolt holes and a 2.62-inch offset provides proper alignment and mounting stability. The flange diameter of 4.882 inches and a hub pilot diameter of 3.306 inches contribute to precise fitment and reduced vibration. Although the ABS encoder type is integrated, the ABS sensor itself is not included. The assembly is constructed from steel for durability and comes with a gasket or seal to maintain proper sealing and prevent contamination. This part is not greaseable and does not include a wiring harness.

Common Applications and Problem Resolution

• Replaces worn or damaged wheel bearing and hub assemblies causing noise or vibration
• Restores proper wheel alignment and rotation for Toyota 86, Subaru BRZ, and related models
• Addresses ABS encoder signal issues due to faulty hub components
• Eliminates wheel stud damage or wear affecting wheel mounting security
• Prevents seal leaks that can lead to premature bearing failure

Installation Notes and Tips

Ensure compatibility with your specific vehicle model before installation. The flange includes four bolt holes and five wheel studs (M12 x 1.25), so verify torque specifications for both flange bolts and wheel lug nuts. Since the ABS sensor is not included, retain or replace the sensor separately if needed. Properly seat the gasket or seal to avoid contamination and premature wear. This assembly is not greaseable, so no additional lubrication is required during installation.
