Have you ever thought about what keeps your engine from moving when you drive? Something has to hold all that torque power in the block in place, right?
It doesn’t go anywhere it shouldn’t because of the motor mounts. But what happens when these mounts wear out? How would you know? How much would it cost to replace them? Just keep reading, and we’ll tell you everything you need to know. Also about signs of a loose motor mount.

Motor Mount Basics
You’ll need to know the basics about the motor mount whether you’re taking your car to a mechanic for repairs or trying to figure out what’s wrong. It’s not a very hard part, but it’s a very important one!
What Motor Mounts Do
Your motor mounts keep your engine in place even when it’s putting out crazy amounts of power and torque. Without motor mounts, every time you revved your engine, it would pull the engine straight up off the frame.
What is a Motor Mount?
Motor mounts are bushings that rub against each other and have a hole in the middle for a bolt. This rubber bushing sits between the frame and engine of the car, and a bolt goes right through it to connect the two parts.
Most engines have four motor mounts, one at each of the four corners. Yes, there are only four bolts holding the engine to the car. Don’t worry, though; these bolts are strong enough to handle all the torque that your engine can throw at them. In fact, the frame of your car will often bend before these bolts break.
Top Signs of a Bad Motor Mount
If you pay attention, it’s not hard to tell if a motor mount has seen better days. If you see any of these signs, you should find your motor mounts and take a closer look.
1. Repeated Loud Noises in the Engine Bay
It might be the first thing you notice when your motor mounts fail. Your engine is held in place by your motor mounts. If one or more of them are worn out, your engine will start to move, which usually makes it bang around a bit.
It’s usually loud, and even people who don’t care about cars will notice it. If you hear loud noises when you rev your engine or turn it on, look more closely.
2. Excessive Vibrations
Even though your engines are moving, you don’t have to hear it, but you will definitely feel it. The engine is very big, and when it moves, it moves the car’s weight around. Whether you’re driving or sitting in the passenger seat, these vibrations will let you know something is wrong.

But just because you feel vibrations doesn’t mean that the motor mount is definitely the problem. There are many things that can cause vibrations that are too strong, so if you feel things you shouldn’t, you need to take a closer look to figure out what’s going on.
3. Engine Moving
Having a friend with you is the best way to check if your engine is running. When someone revs the engine, open the hood and look straight at the engine block. Your engine shouldn’t move if everything is working right.
But if you need to replace one or more of your motor mounts, the engine will “jump” up a little (or a lot if the mounts are really bad!). If your engine moves when you rev it, it’s always the motor mount. But you’ll still need to figure out if you need to replace all of your motor mounts or just one of them.
Engine Motor Mount Replacement Costs
Several things go into figuring out how much it will cost to replace your motor mounts. The two most important things to think about are what car you drive and where you get it fixed. Dealerships will always charge more, while smaller shops tend to be a little cheaper.
But when you take your car somewhere, the most important thing is to find a place you can trust to do the job. Even if it costs a little more, it’s better to know that the mechanic did the job right so that you and everyone else on the road are a little safer.
Part Costs
Motor mounts are not expensive on their own. Depending on what you drive and how big it is, a motor mount usually costs anywhere from $40 to $200. The cost goes up with the size of the engine and the motor mount.
If only one motor mount is broken, you don’t have to replace them all. But since most motor mounts need to be replaced every five to seven years, you might want to get them all done at once to save yourself some trouble in the future.
Labor Costs
You might get lucky and find the motor mount for your car for about $40, but the most you can expect to pay for a mechanic to fix the problem is about $180. Depending on what kind of car you have and where you take it to get fixed, the labour alone could cost you close to $400.
Sometimes the motor mounts on your car are easy to get to, and sometimes you have to take off other parts to get to them. This is the main reason for the big differences in prices.
But if you need to replace one motor mount, it usually doesn’t cost much to do the others at the same time. That’s because all the mechanic has to do to take the pressure off that mount and replace it is move the jack to a different part of the engine. After you’ve set up everything for the first one, it’s easy to move the jack and change the mounts.

When you add up the costs of labour and parts, replacing your motor mounts costs between $220 and $600. But this is usually how much it costs to replace one motor mount. If you decide to replace all four mounts at the same time, you can save money.
The average cost for all four mounts will be between $360 and $1,200, and all of the extra costs are basically just part costs. That’s because it’s easy for the mechanic to switch out the other mounts at the same time as he or she changes out one mount.
Replacing Your Own Motor Mounts
Changing your motor mounts isn’t as hard as it might sound at first if you have the right tools. After you take the bolts off, you’ll need to be able to lift the engine off the mount. If you have the right lifts and jack stands, this is a pretty easy process.
If you do the job yourself, you can save a lot of money on labour costs. A 300-dollar job can quickly become a 40-dollar job if you do it yourself. Even though it might be pretty easy if you know what you’re doing, it will still take you a few hours to finish everything.
But if you don’t know much about mechanics, it’s best to let a pro do it. If you don’t know what you’re doing and you jack up your engine a little and move parts around, it could fall on you and seriously hurt or kill you.
What Happens If You Don’t Replace Your Motor Mounts?
Motor mounts are an important part of your car that is often overlooked. But when they act up, they go from being in the background to being the centre of attention. They are important parts of your car, and even though they can be hard and expensive to replace, you shouldn’t put it off if you don’t have the right tools.
When a motor mount breaks, the engine no longer has a place to rest. As it jumps and skips around the engine bay, it hits all kinds of things it shouldn’t and puts a lot of pressure and torque on parts that can’t handle it.
As it gets worse, it’s only a matter of time before it hurts your engine or other parts of your car in a way that can’t be fixed. Motor mounts aren’t too expensive, but if you don’t fix the problem in time, you might have to replace the whole engine or transmission.
Don’t take a chance. As soon as you see that your motor mounts are getting worn, you should get new ones.
Summary
Don’t forget about your motor mounts. They usually work in the background and aren’t noticed, but if your engine starts jumping around in the engine bay, you’ll miss how reliable they are.
Motor mounts are important parts of your car. They can be hard to replace, but you shouldn’t put it off. Once you know that they are the problem, you need to take it to the shop as soon as possible. If you don’t, your small problem can quickly become a big one.
