Product Description
The genuine Nissan 20640-37J00 exhaust insulator (hanger rubber / mount) is designed for the secure and flexible mounting of the exhaust system to the vehicle chassis. Its primary function is to provide mechanical support for hot exhaust pipes and mufflers while absorbing vibrations caused by engine operation and road irregularities, preventing them from transferring to the body structure (NVH dampening).
Technical Specifications and Operation:
- Part Type: Exhaust system hanger rubber / mount (Insulator)
- Manufacturer: Nissan (OEM)
- OEM Part Number: 20640-37J00
- Mounting Location / Position: Mounting points between the exhaust pipe and the chassis frame
- Material Construction: Industrial elastomer rubber compound resistant to high temperatures, weathering, road salt, and deformation
Wear and Failure Symptoms: Under continuous thermal stress and dynamic mechanical loads, the rubber can harden, stretch, or crack over time. Typical signs of failure include metallic knocking noises over rough surfaces (the exhaust contacting the underbody), excessive sagging or swinging of the exhaust pipe, and increased resonance felt inside the cabin.
