Detailed Product Overview

National 3087 is designed for front inner wheel seal service where accurate sizing matters. The seal’s 2.048-inch shaft diameter, 2.732-inch outside diameter, and 0.590-inch width help match the hub and bore dimensions used on many classic Dodge Ramcharger, D150, D250, B-series van, and Plymouth PB applications. National has supplied sealing solutions for decades, and this part reflects that focus on dimensional accuracy and material selection.

This part cross-references SKF 20425 for the same application. If you are replacing a worn seal on a Dodge Dakota, Dodge Ramcharger, or Chrysler Newport front inner hub, National 3087 provides a direct-fit sealing option based on the listed vehicle data.

Common Repair Uses

• Oil seepage at the front inner hub
• Contamination entering the wheel bearing area
• Seal wear from age, heat, or mileage
• Loss of sealing at the shaft-to-housing interface
• Service replacement during front hub or axle work

Installation Notes and Tips

Confirm the shaft, housing bore, and width measurements before installation. Clean the hub bore and sealing surface thoroughly, and inspect the mating surfaces for grooves or damage that could affect seal life. Verify the vehicle’s hub and axle configuration, since several listed applications require specific stud counts or axle ratings.
