Over time, the original insulating bush can become brittle, worn, cracked, or distorted through age, repeated steering wheel removal, and continual exposure to heat and vibration. A deteriorated bush can result in poor alignment of steering wheel components, intermittent horn operation, or constant horn activation caused by unintended electrical contact. Replacing the insulating bush restores the correct insulation and positioning of the steering wheel assembly, making this OE Match component ideal for Porsche maintenance, repairs, and restoration projects.  

What This Product Does:

• Electrically insulates steering wheel components.
• Helps ensure correct operation of the horn contact system.
• Maintains the correct positioning of the steering wheel assembly.
• Prevents unwanted electrical grounding.
• Replaces worn, cracked, or damaged insulating bushes.
• Supports reliable steering wheel and horn functionality.
• Provides an OE-style fit for straightforward installation.

Symptoms Of Wear Or Failure:

• Excessive play within steering wheel components.
• Cracked, brittle, or distorted insulating bush.
• Electrical contact wear within the steering wheel assembly.
• Difficulty correctly assembling the steering wheel components.
• Damage identified during steering wheel refurbishment or restoration.

Why Replacement Matters:

• The insulating bush is a small but essential component that electrically isolates parts of the steering wheel assembly while maintaining their correct alignment. If the bush becomes worn or damaged, unwanted electrical contact can occur, causing unreliable horn operation and reducing the overall integrity of the steering wheel assembly.
• Replacing a deteriorated insulating bush restores the proper insulation and positioning of the steering wheel components, ensuring dependable horn operation and preserving the original function of the steering system. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Insulating Bush for Steering Wheel provides reliable fit, performance, and durability for Porsche maintenance, repairs, and restoration projects.

The horn button bushing is a small but essential component that cushions and locates the horn button within the steering wheel. Over time, the original bushing can become brittle, worn, cracked, or distorted due to age and repeated use, leading to a loose horn button or inconsistent horn operation.

What This Product Does:

• Supports and locates the steering wheel horn button.
• Maintains correct alignment of the horn button assembly.
• Helps ensure reliable horn activation.
• Reduces unwanted movement and vibration.

Why Replacement Matters:

• Replacing the horn button bushing restores secure horn button fitment, dependable horn operation, and the correct factory-style appearance. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match component provides the correct fit, reliable performance, and long-lasting durability, making it an ideal choice for Porsche maintenance, repairs, and restoration projects.
