What It Helps Address

• Contamination from dirt, dust, and moisture
• Grease or fluid loss around the seal area
• Wear-related sealing issues on high-mileage drivetrains
• Noise or driveline concerns tied to a compromised seal

Installation Notes and Tips

Verify the vehicle year, make, model, and position before installation, since this seal is used in rear, front, and right-side locations depending on application. Measure the bore, outside diameter, and width against the original seal to confirm proper fit. Inspect the shaft surface and housing for scoring or corrosion before installing the new seal.
