Detailed Product Description

The WH512301 wheel bearing and hub assembly from MPA Electrical is a new, precision-engineered component designed to meet the specifications of Chrysler and Dodge vehicles including the 300, Challenger, Charger, and Magnum. Its 27-spline design ensures proper drivetrain connection, while the steel construction provides the necessary strength to withstand road stresses. The flange features a modified rectangle shape with four bolt holes and a diameter of 5.9 inches, ensuring a secure fit. This assembly supports an encoder-type ABS system, allowing integration with the vehicle’s anti-lock braking without including the sensor itself. Additionally, the included gasket or seal helps maintain proper sealing and prevents contamination. The assembly is not greaseable, which aligns with many OEM designs for sealed hub units.

Common Applications and Problem Resolution

• Replacement for worn or noisy wheel bearings causing vibration or roughness
• Fixes wheel hub looseness or play affecting vehicle handling
• Restores proper ABS signal function when the hub encoder is damaged
• Addresses wheel stud damage or corrosion impacting wheel security
• Resolves seal failure that leads to grease leakage and premature bearing wear

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. Clean the mounting surface thoroughly to remove debris and old sealant. Verify the flange bolt hole alignment and torque specifications according to the vehicle manufacturer’s guidelines. Since this assembly is not greaseable, avoid adding grease to the bearing area. Confirm ABS sensor compatibility and wiring connections if applicable, as the sensor is not included with this part.
