What This Seal Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from dirt, debris, and moisture entering the housing
• Seal wear that can lead to driveline fluid loss
• Service issues on rear outer axle assemblies with Spicer 60, Spicer 60-35, Spicer 60-3, and related ring gear configurations
• Maintenance needs on classic Ford, Dodge, Chevrolet, GMC, Jeep, and Lincoln driveline systems

Installation Notes and Tips

Verify the housing bore, shaft diameter, and thickness before installation to confirm the seal matches the axle assembly. Clean the sealing surfaces thoroughly and inspect the pinion area for wear, scoring, or contamination before pressing in the new seal. For best results, confirm the axle type and rear outer application against the vehicle’s service information before reassembly.
