TOYOTA 90301-99182 Wheel Bearing O-Ring

The Toyota 90301-99182 is a genuine original equipment manufacturer (OEM) wheel bearing O-ring that plays a crucial role in ensuring the seal integrity of the wheel hub and wheel bearing assembly. This precision sealing ring prevents lubricant leakage while offering effective protection against external contaminants.

Key Features and Functions:

• Optimal Sealing: Prevents the premature loss of bearing grease, ensuring continuous and optimal lubrication of the wheel bearing.
• Protection Against Contamination: Forms an effective barrier against water, dust, mud, and road salt, which can penetrate the bearing's internal structure and cause premature wear or failure.
• Superior Material Quality: Manufactured from a specialized, high-temperature and friction-resistant elastomer that withstands engine oils, greases, and extreme environmental conditions.
• Genuine OEM Fit: Engineered to strict Toyota standards, ensuring precise dimensions and long-lasting durability.

Technical Specifications:

• Manufacturer: Toyota (OEM)
• Part Number: 90301-99182
• Product Type: Wheel Bearing O-Ring (Ring, O)
• Material: High-resistance synthetic rubber / elastomer

Signs of Wear or Failure:

• Grease leakage or moisture visible around the wheel hub area.
• Metallic, growling, or humming noises coming from the wheels while driving, caused by lubricant loss or the ingress of dirt.
• Premature wear and free play in the wheel bearing.

When replacing or servicing the wheel bearing, replacing the sealing O-ring is also strongly recommended to ensure maximum safety and prolong the lifespan of the bearing.
