Description
Whiteline W93394 provides rear differential mount center support bushing for 06-15 Mazda MX-5 Miata (NC) / 04-11 RX-8.
How It Works
Differential mounting bushings support the housing as it reacts to acceleration and deceleration loads. Excess movement at a deteriorated mount can contribute to an inconsistent driveline response. Restoring support targets movement at the mounting interface, rather than changing the differential’s internal operation or increasing engine power.
Key Specifications
- Manufacturer part number: W93394
- Position: Rear
Installation & Selection
Inspect the mounting brackets, adjacent bushings and fasteners before fitting. Support the differential securely and use the correct installation orientation. Changes in mount compliance can transmit more noise or vibration into the vehicle; assess the complete mounting system rather than replacing parts solely on the basis of a symptom.
