Detailed Product Overview

The Mevotech MB50325 hub assembly is built for front axle service on high-usage applications where durability and consistent fit matter. As part of the Supreme line, this assembly uses in-house engineering and vehicle-specific design updates to address the demands of larger GM trucks and SUVs. The MB50325 also cross-references MOOG 515197 and Timken HA590843 for the same application.

Use MB50325 when replacing a worn front hub on Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, or GMC Yukon platforms that call for this configuration. The pre-greased design helps simplify service, while the hub’s dimensions and stud count support proper wheel mounting and front-end operation.

Common Problems This Part Can Address

• Front wheel noise from a worn hub bearing
• Excessive play or looseness at the wheel end
• Vibration or rough rotation from hub wear
• Wheel stud or hub mounting wear on the front axle
• Service replacement for high-mileage truck and SUV front hubs

Installation Notes and Tips

Verify front position, stud count, flange bolt pattern, and bearing dimensions before installation. Confirm ABS sensor requirements separately, since this assembly does not include an anti-lock brake sensor. Always inspect related suspension and brake components during hub replacement to help ensure a complete repair.

Quality Assurance

Mevotech Supreme hub bearing assemblies are engineered for commercial and passenger vehicle use, including fleets and working trucks. MB50325 is built around application-specific design updates and Labor Saver features that help reduce installation time and effort.
