Detailed Description

SKF 14393 is engineered as a wheel seal for rear-position driveline service, with dimensions that support proper sealing at the shaft and housing interface. SKF has a long history in seal design and uses premium materials and application-specific construction to help keep lubricants in and contaminants out. This part is listed for 1990-2002 Chevrolet Astro, rear and 1990-2002 GMC Safari, rear, making it a direct-fit option for those rear axle seal repairs. If you are servicing a Chevrolet Astro rear wheel seal or a GMC Safari rear wheel seal, SKF 14393 provides the dimensional accuracy needed for a proper replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Helps Address

• Gear oil or lubricant leakage at the wheel end
• Contamination entering the axle or hub area
• Seal wear from age, heat, and road exposure
• Noise or driveline issues related to low lubricant levels
• Repeat seal failure caused by incorrect sealing dimensions

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation to ensure the seal matches the hub and axle dimensions. Inspect the sealing surface for scoring, corrosion, or wear before fitting the new seal. Clean the bore and sealing area thoroughly so the seal seats evenly and maintains consistent contact. For Chevrolet Astro and GMC Safari rear applications, verify the rear position and compare the removed seal to SKF 14393 before assembly.
