TOYOTA 69403-60011 Rear Door Stopper Sub-Assembly

The genuine TOYOTA 69403-60011 rear door stopper sub-assembly is a premium quality, genuine OEM component that plays a crucial role in the stable and secure retention of the vehicle's rear door or tailgate. This unit minimizes vibrations during driving and protects the latch and hinge mechanisms from unnecessary mechanical stress.

Key Functions and Operating Principle:

• Load Relief and Positioning: When the door is closed, the stopper precisely aligns the door panel relative to the body, absorbing a portion of the vertical and lateral loads.
• Vibration Damping: The specialized rubber and elastomer compound absorbs shocks caused by road irregularities, preventing unpleasant rattling and knocking noises inside the cabin.
• Structural Protection: Reduces stress acting on the hinges and latch assembly, thereby significantly extending the service life of adjacent components.

Technical Specifications:

• Manufacturer: TOYOTA (Genuine OEM part)
• Part Number: 69403-60011
• Material Composition: Weather-, ozone-, and wear-resistant rubber compound with a metal mounting core for maximum deformation resistance.
• Fitting Position: Rear door / tailgate frame.

Signs of Wear and Failure:

Over time, rubber components deteriorate due to UV radiation, temperature fluctuations, and continuous mechanical stress. Typical symptoms of failure include:

• Cracking, softening, or complete detachment of the rubber surface from the metal core.
• Metallic rattling or squeaking noises from the rear door while driving.
• Improper door alignment (shifted gaps) or difficulty closing the door.
