What This Wheel Seal Helps Address

• Grease leakage at the wheel bearing area
• Contamination from road dirt, dust, and moisture
• Premature wear caused by compromised wheel-end sealing
• Service issues on front hub and bearing assemblies
• Application mismatch when replacing an OE-style wheel seal

Installation Notes and Tips

Verify the seal type, bore diameter, outside diameter, and width before installation. Match the vehicle position exactly, since this part is listed for both front and front inner applications depending on the model. Confirm brake and axle notes such as JD5 brakes, 8600 lb. G.V.W., I-beam suspension, or IFS axle requirements before ordering. Clean the hub and bearing surfaces thoroughly and inspect the bearing and spindle for wear before installing the new seal.
