SKF 20431 Wheel Seal for Front Outer Applications

SKF 20431 is a wheel seal built for front outer driveline and axle service on select Toyota Corolla, Mitsubishi Mirage, Geo Prizm, and Dodge Colt applications. It is designed around precise dimensions and sealing materials to help maintain lubricant retention and keep road contaminants out.

Key Features

• Wheel seal for front outer positions
• Outside diameter: 2.603
• Shaft diameter: 2.047
• Width: 0.295
• Polyacrylate sealing surface type
• SKF part number 20431 for direct identification

Detailed Description

SKF 20431 is engineered as a sealing component for driveline and axle service where consistent fit and sealing performance matter. The listed dimensions, including the 2.603 outside diameter, 2.047 shaft diameter, and 0.295 width, help match the seal to the intended front outer wheel seal application. The polyacrylate sealing surface type supports the seal’s role in retaining lubricants while helping block dirt, moisture, and other contaminants.

This part is a direct fit for applications such as 1988-2002 Toyota Corolla, front outer; 1993-2002 Mitsubishi Mirage, front outer; 1989-1997 Geo Prizm, front outer; and 1993-1994 Dodge Colt, front outer. It also covers 1992 Mitsubishi Mirage, front outer from 6/92 and 1987 Toyota Corolla, front outer from 8/87. SKF 20431 is a practical replacement choice when servicing these wheel-end sealing points.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Gear oil or grease leakage at the wheel-end seal area
• Contamination entering the hub or axle sealing surface
• Wear-related sealing loss on front outer applications
• Noisy or rough operation caused by compromised lubrication retention
• Service replacement needs on Toyota Corolla, Mitsubishi Mirage, Geo Prizm, and Dodge Colt models

Installation Notes and Tips

Verify the shaft diameter, outside diameter, and width against the original seal before installation. Inspect the sealing surface and surrounding components for wear, scoring, or contamination that could affect sealing performance. Clean the mating surfaces thoroughly and install the seal squarely to avoid distortion. Confirm the vehicle’s build date when applicable, especially for 1987 Toyota Corolla from 8/87 and 1992 Mitsubishi Mirage from 6/92.
