Rattling And Clunking Noises
If the motor mounts in your car are beginning to go, the engine will shake and rattle more than usual, because its not held firmly in place by something thats absorbing the movement. When this happens, the car will begin to make some rattling noises, that hopefully get your feelers up.If the mounts arent fixed, that will lead to a clunking noise whenever you put your car in gear, which will eventually evolve into a clunking noise whenever you use the gas pedal, brake pedal, or drive over any bumps.When your car talks, listen.

How Important Is This Service
Engine mounts hold your engine and transmission in place. The mounts absorb the shocks of the road and the vibration of the engine and transmission, and keep these two elements securely in place. When a mount brakes, the engine and transmission are less secure, and theyre subject to a higher amount of vibration and shock. This can cause damage to any number of vehicle components, and will also make your ride much rougher.

When Should You Have The Motor Mounts Replaced
Like just about every part of your car, the motor mounts are affected by wear and tear and can eventually fail over time. Car engines are large, heavy bits of equipment and a lifetime of stops, starts, bumps and turns will all take their toll on the mounts. They can crack, the rubber fixtures can wear out or become spongy, and they can even just crumble apart in the right circumstances.
One way in which the erosion is accelerated is by liquid from the engine making its way into the mounts. Common culprits include motor oil, transmission fluid, power steering fluid and any other liquid involved in the operation of an engine.
Other common reasons for motor mount failure include engine modifications which make your 2015 Jeep Patriot more powerful than the original design, as well as aggressive driving and cornering.
For smaller cars, its a little easier to check for cracks in the mounts than with larger cars. Usually a strong two-handed push should move the engine enough to check the mounts for any cracks or breaks in the mount. For larger cars, a visit to a garage is the best option to assess any possible damage.

What Are Motor Mounts
The majority of cars have several engine mounts, usually made from steel and rubber. In the event one of the mounts breaks, you will be aware of a substantial amount of movement in the engine, including increased vibration and shaking.
If you notice this additional movement in the engine, make sure you have it inspected by a mechanic as soon as possible. If you drive your 2015 Jeep Patriot for too long with a broken engine mount theres a real chance of causing significant damage to the transmission and the axle shafts, which will be a far more expensive repair.
The mounts are not usually checked during the general maintenance of a car, so its important that youre aware of any major changes to how your 2015 Jeep Patriot feels when you drive it. If you experience any of the symptoms described here, take it in to your local garage to have it checked out.
Any unusual noises or vibrations could be linked to engine mount issues, but the main things to look out for are clunking noises or engine movement, significant vibration when accelerating, any movement in the engine compartment when turning, or leaking oil which may be from a damaged mount.
How Does The Engine Mount Work
There are typically two or more engine mounts in a vehicle. Depending on the vehicle configuration, the engine will either rest on mounts bolted to the vehicle subframe, or will be suspended by mounts bolted to the vehicle’s actual frame. In the case of front wheel drive vehicles, these mounts may also support the transmission from the side, and with stabilizers from above. There are several styles of mounts, ranging from solid rubber, to liquid filled.
Most modern motor mounts use a liquid filled core, which is contained inside of a composite rubber insert. This allows the mount to flex as needed while still preventing the vehicle from absorbing the vibrations and noise from the engine. This composite rubber insert, also called the insulator, is encased in a metallic housing to provide a firm, stable mounting surface for the engine and transmission, and the portion that connects to the engine is inserted into the insulator and secured via bolts. This design suspends the engine by composite rubber instead of metal.
