What This Seal Helps Address

• Gear oil seepage at the front differential pinion area
• Contamination from dirt, dust, and moisture entering the seal surface
• Lubricant loss that can affect differential operation
• Wear at the pinion seal interface on high-mileage driveline service
• Replacement needs for front differential maintenance on Silverado, Sierra, Tahoe, Yukon, and Escalade models

Installation Notes and Tips

Verify the bore diameter, outside diameter, and seal width before installation. Clean the housing and pinion surface thoroughly, and inspect the mating surface for scoring or wear that could shorten seal life. Confirm front axle and ring gear configuration against the vehicle listing, especially on applications with 8.25-inch or 9.25-inch ring gear notes.
