What This Seal Helps Address

• Gear oil seepage at the front axle shaft
• Contamination entering the axle housing
• Seal wear from age, heat, and road exposure
• Fluid loss that can affect driveline lubrication
• Noise or driveline concerns related to low lubricant level

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation to match the axle housing and shaft interface. Inspect the axle shaft surface for scoring or corrosion, since surface damage can shorten seal life. Clean the sealing bore thoroughly and install the seal squarely to avoid distortion. For front left or front right Hummer H3 and H3T applications, verify side-specific placement before service.
