Detailed Description

National 714675 is an oil seal engineered for differential pinion service where accurate shaft fit and housing bore dimensions matter. The seal measures 1.844 inches on the inside diameter, 2.753 inches on the outside diameter, and 0.425 inches in thickness, with a 3.089-inch flanged outside diameter. Its fluoro-elastomer material and bi-directional lip design are suited to axle assemblies that need dependable fluid control at the pinion area. This part cross-references Gates 18472 for the same application. It is a direct-fit option for vehicles such as Ford Ranger, Mazda B4000, and Jeep Grand Cherokee in the listed front outer or rear outer positions.

What This Seal Helps Address

• Gear oil leakage at the differential pinion area
• Contamination entering the axle housing through a worn seal
• Fluid loss that can lead to noisy or overheated differential operation
• Seal wear from age, heat, and driveline movement
• Service replacement needs on front outer and rear outer axle positions
