Engine hydro-mounts may show surface cracks. This will not effect performance and mount should not be replaced. Only replace the engine hydro-mounts when leaking fluid:
- Driveshaft diagnosis. Refer to Transmission and Drivetrain.
- Any front end structural damage (after repair).
- Isolator replacement.
