This part cross-references no listed interchange numbers in the provided data. For service work on Cadillac DeVille, Chevrolet K10, or GMC Jimmy driveline assemblies, confirm the seal dimensions against the housing and shaft before installation.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from road debris and moisture
• Seal wear caused by age and heat cycling
• Loss of sealing integrity around the shaft interface
• Service issues on front or transfer-case-related applications

Installation Notes and Tips

Verify the shaft diameter, housing bore, and seal dimensions before installation. Clean the sealing surface thoroughly, inspect for scoring or wear, and install the seal squarely to avoid distortion. For vehicles such as Cadillac Fleetwood, Chevrolet K20 Suburban, or GMC K2500 Suburban, confirm the exact application notes, including transfer case or transmission requirements, before service.
