Features & Advantages
- OE Quality: Manufactured to strict dimensional and material specifications for perfect fit and function
- Precision Sealing Lip: Engineered to maintain consistent contact pressure for reliable lubricant retention
- Garter Spring Design: Ensures lip tension remains constant, compensating for minor wear and temperature fluctuations
- Durable Material: High-grade NBR rubber provides excellent resistance to gear oil, heat, aging, and weathering
- Rust-Protected Casing: Metal casing is coated or treated to resist corrosion from road salt and moisture
- Contaminant Exclusion: Effectively blocks water, mud, dust, and debris from entering the wheel bearing cavity
- Lubricant Retention: Prevents rear axle lubricant leakage, avoiding bearing starvation and potential axle damage
- Extends Bearing Life: Proper sealing dramatically increases rear wheel bearing service intervals and reliability
- Direct Replacement: Simple installation during rear axle or brake service
- Cost-Effective Maintenance: Prevents expensive wheel bearing, spindle, and axle repairs

Installation Procedure
- Raise and secure the vehicle – Safely lift the rear axle and remove the rear wheels, brake drums, and hub assembly
- Remove the old outer seal – Carefully pry out the old seal using a seal puller, taking care not to score the hub bore
- Inspect hub bore and spindle – Check for scoring, pitting, or wear; repair or replace components as needed
- Clean thoroughly – Clean the hub bore and spindle surface with solvent; ensure no old seal debris remains
- Lubricate the new seal lip – Apply a thin coat of clean axle oil or assembly grease to the sealing lip
- Position the new seal – Align the seal squarely with the hub bore (lip facing inward toward the bearing)
- Install the seal – Use a proper seal driver or appropriate-sized socket to press the seal evenly into the bore until fully seated
- Pack bearings and fill with lubricant – Repack wheel bearings with grease or fill hub with axle oil per manufacturer specs
- Reinstall hub assembly – Mount the hub, ensuring the seal lip rides smoothly on the axle spindle surface
- Adjust bearing preload – Tighten the bearing nut to the specified torque and set end-play per service manual
- Top up axle oil – Refill the rear axle differential with the correct grade and amount of gear oil
- Test for leaks – After a road test, inspect for any signs of lubricant leakage at the hub seal
Quality Control
- Material Verification: Confirms rubber compound and metal composition meet OE specifications
- Dimensional Inspection: Inner diameter, outer diameter, and width verified against OEM tolerances
- Lip Geometry Check: Sealing lip profile and angle inspected for optimal sealing performance
- Garter Spring Tension: Spring force measured to ensure consistent lip pressure
- Hardness Testing: Rubber durometer tested to OEM standards for durability
- Visual Inspection: 100% checked for cracks, flash, molding defects, or damage
- Packaged Safely: Individually sealed to prevent contamination and protect the sealing lip during transit
