How many miles should motor mounts last?
Motor mounts, also known as engine mounts, are an essential component of a vehicle's suspension system. They are responsible for securely holding the engine in place and absorbing vibrations to provide a smooth and comfortable ride. The lifespan of motor mounts can vary depending on several factors, but on average, they should last between 60,000 to 90,000 miles.
What Are Motor Mounts?
Motor mounts are rubber or hydraulic components that connect the engine to the vehicle's frame or chassis. Their primary function is to isolate the engine from the rest of the vehicle, reducing the transmission of vibrations and noise. This helps to create a more comfortable driving experience and protects other components from excessive wear and tear.
Factors Affecting Motor Mount Lifespan
The lifespan of motor mounts can be influenced by several factors, including:
- Driving Conditions: Vehicles that are driven in harsh conditions, such as off-road or on rough roads, may experience more wear and tear on their motor mounts, leading to a shorter lifespan.
- Engine Power: Vehicles with more powerful engines tend to put more stress on the motor mounts, which can lead to faster deterioration.
- Age and Mileage: Over time, the rubber or hydraulic components in motor mounts can become worn, cracked, or hardened, reducing their effectiveness.
- Maintenance: Regular inspections and timely replacement of worn motor mounts can help extend their lifespan.
It's important to note that the recommended replacement interval for motor mounts can vary depending on the make and model of the vehicle, as well as the specific driving conditions and usage.
Signs of Worn Motor Mounts
When motor mounts begin to wear out, they can exhibit several signs, including:
- Excessive Engine Movement: If the engine is noticeably shifting or rocking during acceleration, braking, or idling, it may be a sign of worn motor mounts.
- Vibrations and Noise: Worn motor mounts can allow more vibrations and noise to be transmitted from the engine to the rest of the vehicle, which can be felt and heard by the driver.
- Uneven Tire Wear: Worn motor mounts can cause the engine to be misaligned, leading to uneven tire wear and handling issues.
If any of these signs are observed, it's important to have the motor mounts inspected and replaced as soon as possible to prevent further damage to the vehicle.
At what mileage do engine mounts go bad?

How do you know when engine mounts need replacing?
Signs you need to check or replace the motor mounts are clunking or knocking noise when shifting from park to reverse or park to drive, vibration at idle, vibration at the brake pedal, engine movements, fluid leaks from engine mount, cracked or missing rubber on mount.
How often should motor mounts be replaced?
How Long do Engine Mounts Last? Usually, engine mounts should last between at least 5-7 years, depending on the application.
Is it OK to drive with bad motor mounts?
A failing motor mount can lead to serious engine damage and will also greatly impact the performance of the vehicle. It is very unsafe to drive with a broken motor mount. If you feel a lot of vibration in the vehicle while you are driving, there's a good chance it's the motor mount.
