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:

• Horn operating intermittently.
• Horn sounding continuously without pressing the horn button.
• 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.
