How do these seals help when I have a rear hub oil leak?

Replacing worn or damaged inner axle seals stops oil from escaping the hub area and prevents dirt and moisture from entering bearings. Proper sealing preserves bearing life and maintains correct axle lubrication, which is important for safe, reliable operation under load. Use new o-rings to ensure seal retention and proper engagement with the hub housing.

• Stops lubricant loss that can damage bearings
• Prevents contaminants from entering hub and axle assembly
• O-rings ensure a secure seal between components
• Two axle seals and two o-rings included for both sides

Eterpace subjects each kit to inspection routines before shipping to reduce the chance of dimensional or material defects. You’ll also see listed replacement part numbers to help confirm correct selection for your vehicle.

How do I install these seals and what should I watch for?

Installation typically requires removing the hub assembly and carefully extracting the old seal without damaging the bore. Press the new seal squarely into place and replace the o-ring where indicated; use proper torque on hub fasteners during reassembly. If you’re unsure, consult a service manual or a qualified mechanic to avoid drivetrain damage.

• Remove hub and clean seating surfaces thoroughly
• Press seals evenly to avoid lip damage or misalignment
• Replace o-rings and lubricate sealing surfaces lightly before install
• Re-torque hardware to manufacturer specifications
