NISSAN 40579-VB000 Grease Seal Kit

The genuine NISSAN 40579-VB000 (Grease wiper seal kit / SEAL-GREASE) is a premium quality, original OEM part designed for the reliable sealing of the vehicle's front axle and swivel hub assembly. This seal plays a critical role in protecting suspension and drivetrain components by ensuring lubricant retention and excluding external contaminants.

Key Technical Features and Functions:

• Effective Lubricant Retention: Prevents leakage of the specialized grease required to lubricate the constant-velocity (CV) joint and wheel hub bearings.
• Protection Against Environmental Influences: Seals the assembly against water, mud, dust, sand, and other abrasive contaminants, preventing premature wear and corrosion of internal components.
• Premium Material Quality: Manufactured from a high-grade elastomer (special rubber compound) offering high thermal and chemical resistance, withstanding continuous mechanical stress, friction, and the chemical effects of lubricants.
• Factory Fit (OEM): Manufactured to genuine Nissan specifications, ensuring exact dimensional tolerances and a reliable seal in the installation position.

Common Symptoms of Wear or Failure:

• Visible Grease Leaks: Grease deposits appearing on the inner side of the swivel housing or the inside of the wheel.
• Contaminant Ingress: Crunching, clicking, or growling noises when turning, indicating lubricant starvation and contamination inside the CV joint or bearings.
• Visual Deterioration: Cracking, hardening, tearing, or deformation of the seal ring noticed during routine maintenance inspection.

Replacing the seal in a timely manner helps prevent costly repairs to the drive axle and suspension components. For maximum service life and safe operation, the use of genuine NISSAN parts is recommended.
