National 4898 Wheel Seal - Front Outer or Rear Outer

National 4898 Wheel Seal Overview

National 4898 is a metric wheel seal built for front outer and rear outer applications on select import vehicles. It uses nitrile material and precise dimensional sizing to help maintain a reliable seal at the wheel end, including 52.000 mm shaft diameter and 66.120 mm outside diameter specifications.

Fits 1988-2002 Toyota Corolla, front outer; fits 1987-1989 Toyota MR2, rear outer; and fits 1998-2002 Chevrolet Prizm, front outer. This National 4898 seal also cross-references Beck/Arnley 052-3432 for the same application.

What This Seal Helps Address

• Wheel-end fluid leakage at the seal interface
• Contamination from road debris, water, and dust entering the hub area
• Wear-related seal failure on high-mileage front outer or rear outer positions
• Noise or service issues caused by compromised wheel-end sealing
• Dimensional mismatch when replacing an OE-style metric wheel seal

Installation Notes and Tips

Verify shaft diameter, housing bore, and overall width against the vehicle service information before installation. Clean the bore and shaft surface thoroughly, inspect for scoring or corrosion, and install the seal squarely to avoid lip damage. Confirm the application position matches the vehicle listing, such as front outer or rear outer, before final assembly.
