Motor mounts serve several purposes: They reduce engine vibrations, ensuring a smoother and more comfortable ride for you and your passengers. They keep the engine securely in place, preventing it from moving around or shifting during acceleration, braking, or turning.
When your engine mounts have failed you may notice your vehicle lurching forward when you start the engine. This lurch then usually turns into a constant vibration, but you may then also feel a lurch when the ignition is turned off.
An engine mount's primary purpose is to secure an engine into machinery and absorb any shocks and vibrations when the machinery is operating. Engine mounts and anti-vibration mounts are essential for preventing damage to the engine and improving operator comfort (where applicable).
