Detailed Description

MB40345 is a front wheel bearing and hub assembly engineered for select Ford Explorer and Lincoln Aviator models. The assembly uses a Gen 3 bearing generation and arrives pre-greased, which supports efficient replacement of a worn hub unit while maintaining the correct wheel-end interface. Mevotech MB40345 is built for high-usage passenger vehicles, SUVs, fleets, and working trucks, making it a practical choice where repeat service and consistent performance matter.

This part cross-references Ford and Motorcraft applications (e.g., HUB446, LB5Z1109A) for the same application.

What It Helps Solve

• Wheel bearing noise from a worn hub assembly
• Excessive wheel play or looseness at the hub
• Rough wheel rotation caused by bearing wear
• ABS-related service concerns when the sensor is not part of the assembly

Installation Notes

Verify front fitment before ordering. Confirm hub dimensions, stud count, and flange bolt pattern against the original part. Because the ABS sensor is not included, transfer or source the sensor separately if your application requires it.

Quality Assurance

Mevotech Supreme Parts are engineered in-house with application-specific upgrades for durability and performance. The Supreme hub bearing assembly line also incorporates Labor Saver designs to make installation faster and easier.
