TOYOTA 43436-60011 Knuckle Gasket

The Toyota 43436-60011 genuine (OEM) knuckle gasket is a high-precision sealing component designed to seal the critical junction between the front axle and the steering knuckle (spindle). This part is essential for protecting drivetrain and suspension components, particularly in Toyota solid-axle and independent suspension four-wheel drive (4WD) systems.

Key Functions and Importance:

The primary role of the knuckle gasket is to provide dual-sided protection:

• Lubricant Retention: Prevents specialized grease within the knuckle housing from leaking out, ensuring continuous and proper lubrication of the constant velocity (CV) joint.
• Contaminant Exclusion: Creates an effective barrier against environmental elements, preventing water, mud, dust, and other abrasive debris from reaching the bearings and axle shaft.

Typical Symptoms of Failure or Wear:

• Grease or differential oil leakage on the inner side of the wheel hub and the knuckle ball surface.
• Metallic, grinding, or clicking noises from the wheel hub area during cornering due to debris contamination.
• Visible cracking, tearing, or deterioration of the gasket detected during maintenance inspections.
