The lifespan of engine mounts can vary depending on several factors such as the type of vehicle, the quality of the mounts, and the driving conditions. On average, engine mounts can last between 60,000 to 100,000 miles or around 5 to 7 years. However, some engine mounts may last longer or shorter than this depending on the factors mentioned above.
Rubber engine mounts tend to wear out sooner than hydraulic engine mounts because rubber tends to harden and crack over time. While hydraulic engine mounts are more expensive than rubber mounts, they tend to last longer and provide a better isolation of the engine vibration.
It’s important to keep in mind that even if the engine mounts are still functioning, they may have lost some of their effectiveness over time. This can lead to increased engine vibrations and noise, which can be uncomfortable for passengers. That’s why it’s important to have worn engine mounts checked and replaced as necessary to ensure proper engine alignment and performance.
