TOYOTA 90311-62001 Rear Wheel Hub Oil Seal

The TOYOTA 90311-62001 is a genuine OEM rear wheel hub oil seal (shaft seal ring) that plays a critical role in the reliable operation of the vehicle's running gear and suspension system. This precision sealing component ensures proper lubrication of the wheel hub bearing while protecting the assembly from environmental contaminants.

Technical Features and Functions:

• Lubricant Retention: Prevents the leakage of wheel hub bearing grease or axle housing gear oil.
• Contaminant Protection: Forms an effective barrier against dust, mud, water, and other road debris, preventing them from entering the bearing cavity.
• Brake System Protection: Prevents leaking lubricant from reaching the brake drum or brake disc, directly contributing to maintaining safe and reliable braking performance.
• Premium Material Quality: Manufactured from a high-temperature and wear-resistant elastomer capable of withstanding continuous friction and extreme temperature fluctuations. Features an integrated metal reinforcement casing and tension spring for an exact, reliable fit.

Technical Specifications:

• Manufacturer: TOYOTA (Original Equipment Manufacturer)
• Part Number: 90311-62001
• Product Type: Rear wheel hub oil seal (shaft seal)
• Fitting Position: Rear axle, wheel hub

Typical Signs of Wear or Failure:

• Oil or grease stains appearing on the inner side of the rear wheel rim or on the brake backing plate.
• Sudden or gradual loss of braking efficiency due to lubricant contaminating the friction surfaces.
• Abnormal humming, rumbling, or grinding noises from the rear wheel hub caused by bearing wear due to lubricant starvation or debris ingress.

If the seal is damaged or deteriorated, immediate replacement is recommended to prevent premature failure of the wheel hub bearing and degradation of braking performance.
