If your car shakes when accelerating on the road, it could be a few things. First, check whether your tires are wearing unevenly. If so, you'll need to get them rotated or changed. If not, it could be that the engine is vibrating due to a problem with its mountings or the transmission.
Your car shakes when accelerating is a widespread issue. While it does not usually indicate that your car is about to burst into flames, it can still be a sign of bigger issues further down the road.
There are countless reasons why your car might shake when accelerating or going over bumps in the road: bad spark plugs, worn out brakes, faulty tires among other examples.
Luckily for you, we have compiled this list of 12 causes of shimmy and vibration in cars -- along with easy solutions.
Different Things Can Cause Your Car To Shake When Accelerating
First, let us get some things out of the way. The first thing to do is to identify what is causing your car to shake when accelerating.
There are many different causes for this problem and it is important to know exactly what you are dealing with before moving on to solutions.
If your car shakes when shifting gears or accelerating, there might be something wrong with the transmission or its motor mounts; if it only shakes at high speeds, then perhaps it has something to do with how well-balanced your tires are; among other examples.
Once you have identified and understood the source of your problem, you can proceed with a fix.
Some fixes will be easier than others. For example, replacing worn-out parts with brand new ones may cost quite a bit of money but will not require much work on your part.
While changing out gas filters might require more skill/time investment but save money overall in repair costs over time (since they prevent clogged fuel lines).
Regardless of which solution works best for each person's situation, there are always ways around these problems, so do not give up hope just yet.
12 Causes of Car Shakes When Accelerating
#1. Faulty Spark Plugs
If you’re experiencing a car shakes when accelerating, one of the most likely causes is faulty spark plugs. You need to replace spark plugs every 100,000 miles or so, and they’re inexpensive and easy to replace by yourself.
However, if you do not know how to replace your own spark plugs (or even if you do), we recommend taking it into a mechanic instead of trying this at home as it may cause damage if done incorrectly.
The ignition coil is the heart of your engine, and it's one of the most important parts in your car. It's what fires off your spark plugs so that you can get your car moving. If your ignition coil isn't working right, then it could be making your car run slower or not at all.
#2. Faulty Ignition Coil
The ignition coils are responsible for producing a high voltage to ignite the spark plugs. If the ignition coil is faulty, the car will shake violently when accelerating. The shaking can be severe enough that you may find it difficult to control your car while driving.
A short in wiring or a bad connection could cause faulty ignition coil. This type of problem is often easily solved by replacing the defective part with an identical new one and installing it correctly on your vehicle's engine block.
#3. Dirty Fuel Injector
A dirty fuel injector is another cause of shaking when accelerating. The fuel injectors mix gasoline with air and create pressure in the engine to ignite it. If you have a dirty fuel injector, the engine may not be getting sufficient gas or air to work properly and may shake when you accelerate.
To check your fuel injectors, follow these steps:
Start your car and let it run for two minutes without touching anything inside the vehicle or outside of it (Do not close your garage door). This will allow any fumes from cleaning chemicals or old gasoline in the lines to dissipate before you start testing them out.
Turn off your car completely by pulling out its ignition key once again; this is important because if there are any fumes still lingering inside your vehicle they might interfere with our test results later down below. Now that we have got that covered let us go ahead ensure everything else checks out okay too...

#4. Worn Out Air Filter
If your air filter is dirty, replace it. If you have an old or inexpensive car, it might already have a clogged air filter that you need to replace with a better one. If not, clean the old one thoroughly and wash out any loose particles before replacing it.
If changing the air filter does not solve your problem, change the engine oil in your car and check if it improves its performance at all.
#5. Bad Oxygen Sensor
A bad oxygen sensor can cause the car to shake when accelerating. The sensor measures the amount of oxygen in the exhaust, and if it is faulty, your car will shake when you accelerate. To check for a bad oxygen sensor:
Turn on your car and look at your dashboard display screen. If it is not working properly, then you may want to consider replacing it with a new one.
Open up your hood and locate where the engine is on top of your engine compartment (the area behind your windshield). Next, go underneath where there should be two hoses coming out from each side that look like "T"s connecting both sides together by crossing over each other (this is O2 sensor). You will want to disconnect these two hoses so that we can swap them out with our new ones.
#6. Loose or Worn Out Engine Mounts
Engine mounts are the rubber or plastic bushings that connect the engine to a car's chassis. They serve two main purposes:
To isolate vibrations from the engine, so they do not transfer to the body of your vehicle and make it feel shaky or rattle when you accelerate.
To reduce noise levels by absorbing some of those same vibrations before they ever reach your ears (and also prevent rattles).
If you have loose or worn out engine mounts, they can cause all kinds of problems—including an increase in wear and tear on other parts like your struts and springs. They may also cause alignment issues with your tires.
A faulty transmission system can also cause other problems such as erratic acceleration or deceleration, excessive engine temperatures and oil leaks. If you notice any of these symptoms, then there perhaps something wrong with your transmission system and it should be inspected immediately by an experienced mechanic.
#7. Faulty Transmission System
Transmission problems can also cause a car to shake when accelerating. A transmission problem is often caused by lack of lubrication, but it can also be the result of a repair that was not done correctly or with the right parts.
Replacing the transmission fluid can help prevent further damage and keep your car operating properly. If you notice that your car is shaking more than usual while accelerating, check the oil level and ensure it is full before taking it in for service to avoid expensive repairs down the road.
#8. Excessive Wheel Alignment
If you have a wheel alignment problem, it can cause your car to shake when accelerating. To check if this is the case, you need to take your vehicle in for a wheel alignment check. You can also do this at home by following these steps:
Drive the vehicle on a level surface and note how many degrees each wheel is out of alignment from true center line (if they are). Take the measurements with tires you inflate to recommended pressure levels and aligned according to factory specifications listed on the driver side door jamb sticker or owner’s manual. If any of these measurements exceed specifications by more than three degrees in any direction, then correct them using an adjustable wrench until they fall within limits again before driving off-road again!
You should also check worn tire patterns; scuffing from improper camber settings will create excessive wear on one edge of each tire tread pattern, causing unusual wear patterns that could lead to dangerous conditions, such as blowouts or skidding during sudden acceleration.
#9. Loose or Damaged Wheel Bearing
A wheel bearing is a mechanical device that allows for the rotation of wheels with little friction, and it’s commonly fitted to vehicles.
If your car’s wheel bearings damage or wear out, you might notice excessive play in your steering wheel when you turn it. If this happens, chances are you have a loose or damaged wheel bearing.
To check if your vehicle has a loose or damaged wheel bearing:
Inspect the steering system; listen for clunking sounds while turning the steering wheel back and forth.
Feel around each end of the axle shaft; if there is play between it and its hub, then there is likely damage to some part of its structure (wheel bearings).
#10. Loose or Damaged Brake Rotor or Drum
If you are experiencing a vibrating or your car shakes when accelerating, it may indicate a damage to one or more of your brake rotors. Brake rotors are the discs attached to the wheels and help to stop the wheels from spinning.
The rotors can become damaged when driving over bumps or potholes, which will cause vibrations in your car. Damages can occur if you drive too fast down hills (especially at high speeds).
When you're traveling down the highway, it's important to keep your tires in good condition. Tires that are damaged or worn can cause a car to shake when accelerating. It is also important to ensure that the tire pressure is correct, as this can cause problems as well.
#11. Loose or Damaged Tires
If your car shakes when accelerating, you may have a problem with the tires. It is important to remember that when checking for this issue, you should look at both the front and back tires. They often wear differently and can affect the way your car handles on the road.
When you check your tires, ensure they are not bulging, cracked or leaking air. Ensure they are all the same size and do not have any uneven wear. And ensure they are all properly inflated.

#12. Worn Out Universal Joints
The universal joint transmits the rotation of an input shaft to an output shaft at angles or rotational speeds different than the input shaft, due to its construction and principle of operation.
The most common type of universal joint consists of a pair of concentric cylindrical joints (cages) housed within two end rings (spools).
They are typically made from bronze or brass, but stainless steel is also used because it is corrosion resistant and has good wear resistance at higher temperatures.
Common causes of worn out universal joints:
Wrong driving style -- if you drive fast with poor control over your car's acceleration, then the gears will wear out quickly causing them not only to vibrate but also produce noise due to friction between their surfaces;
Under-powered engine -- An under-powered engine creates problems with wear and tear because it cannot provide sufficient torque or power;
Tires that wear out -- If your tires are badly worn out then they will not be able to handle your car's speed very well, so they will shake when accelerating;
Weak suspension system -- A weak suspension system may not be able to support heavy loads like extra weight in your trunk or trailer hitch.
Diagnose Car Shaking When Accelerating in a Few Steps
A thorough inspection of your car’s components is the best way to diagnose a car shakes when accelerating problem.
Additionally, checking for obvious signs of trouble, such as worn engine mounts or cracked tires, you should also look for less obvious issues that could cause vibrating when accelerating.
Check the brake pads and rotors (if equipped), transmission fluid level, spark plugs, fuel system and shocks and struts.
Solutions For Your Car Shaking When Accelerating
Do you notice that your car shakes when accelerating? If so, then you might have a serious problem. In this article, we will discuss the causes of car shaking when accelerating and how to fix them.
Tire Rotation
Tires wear differently, so you need to rotate them. Rotate your tires every 5,000-10,000 miles. Ensure you rotate the tires front to back, not side to side. This keeps the wear even on each tire and will help reduce vibrations that result from uneven traction.
A brake rotor is a component in the braking system of a vehicle. The brake rotor is attached to the wheel hub and it rotates with the wheel when you step on the brakes. When you press down on your brake pedal, hydraulic pressure forces brake fluid through small channels in the caliper to push pistons which squeeze pads against the rotor and slow down your car or truck.
Check Brake Rotor
A brake rotor is the part of a vehicle’s braking system that the pads press against when you hit the brakes. Hitting a curb or driving over potholes can damage the brake rotor, causing it to warp. If you notice that your car shakes when accelerating because of this issue, you will need to replace your existing rotors with new ones.
Worn Engine Mounts
Engine mounts absorb vibration and keep the engine from moving around. They do this by connecting the engine to the chassis of your car through rubber or metal.
Engine mounts can wear out or break, which causes the engine to shake violently when accelerating.
This will cause a rattling sound in your engine compartment, as well as a shaking motion on the dashboard of your vehicle.
There are several ways you can check for worn out mounts:
Check for any cracks in engine mount rubber pieces. If one has cracked, it will not be able to hold as well as it should, which means vibrations may cause more damage and lead to further wear sooner than expected.
Feel for loose bolts holding together metal parts of an engine mount assembly.
Inspect other parts located near where you expect there might be problems with this particular component (such as transmission shifter brackets).
Transmission fluid is a special oil that helps your car's transmission work smoothly and efficiently. When it leaks out of the system, it means there's a crack in the transmission that you need to fix.
Transmission Fluid Leaks
If you notice that your car is shaking while accelerating, it’s likely due to a transmission leak. Transmission leaks can cause the following symptoms:
A wet spot on your driveway or garage floor.
A metallic smell when you start your car.
Increased oil usage.
You Have a Bad Wheel Bearing
Bad wheel bearing is a common cause of car vibrates when accelerating in your car. Here's how to check for and replace a wheel bearing:
Grab your vehicle manual and look up the torque specifications for the wheel bearing bolts. You will need to know these before you begin this job, as well as what size bit you will need for each bolt (if applicable). Also note where you can locate your jack points on the car, so that if necessary, you can lift it off safely.
To determine if your car has faulty bearings, spin them by hand -- they should be smooth with no rough spots or grinding sounds noted at any point during their rotation. If there is resistance anywhere along its path around its center axis, then there perhaps some play in that wheel bearing which could lead to early failure down the road if not repaired soon sufficient.
Faulty Spark Plugs
You can check your spark plugs for continuity and ensure they are not cracked by using a multi-metre. We recommend a digital multi-meter, as they typically have more accurate readings than analog meters.
Take the spark plug out of the engine bay and clean it with a wire brush to remove any dirt, oil or corrosion that may have accumulated on the surface of the cylinder head where it contacts with its mating surface.
Place one end of your multimeter's probes on each terminal at either side of each spark plug (the label "R" and "L"). There should be no connection if you connect nothing to those terminals. If you see voltage there, then something else might be wrong. This process ensures that there is not an electrical problem elsewhere in your car's wiring harnesses since you know these terminals are open circuits when you connect nothing across them.
Remove each spark plug from its respective cylinder using pliers, then rotate counterclockwise until its threads disengage from their seats within their respective holes before removing completely.
Repeat steps two through four until you remove all four plugs.
Clean off any dirt or grime that may still remain inside these holes by spraying compressed air directly into them while rotating them manually with pliers.
Issues With the Fuel System
Check the fuel filter. The fuel filter is a small screen that gets clogged with dirt and debris over time, which can restrict the flow of gas through your system. If you are having issues with acceleration, check to see if your vehicle's fuel filter is dirty or needs replacing.
Check the fuel pressure. Low pressure in your car's fuel system can create a rattling noise when accelerating because there is not sufficient force pushing gases through the engine at a quick enough rate to cause smooth acceleration. A faulty or damaged hoses can cause this by restricting airflow through these parts of your engine, so take a look under the hood to see if there are any cracked or holes in them. Also ensure that everything is properly secured so nothing gets loose while you are driving down the road—loose screws and bolts could ruin everything from your muffler to something more important like an axle bearing!
Check all injectors' operation while idling; if they are not firing properly then it could lead to poor throttle response during acceleration attempts.
Shock absorbers and struts are essential to your vehicle's stability, comfort, and safety. Shock absorbers dampen shocks, or vibrations, during acceleration and braking. Struts provide a constant spring force that keeps the tires in contact with the road surface.
Need New Shock Absorbers and Struts?
Shock absorbers and struts are part of the suspension system. They are responsible for maintaining the height of your vehicle, which is important because it affects how much clearance there is between your tires and any obstacles that might be in their way.
Shock absorbers also control ride quality, helping to ensure that bumps do not affect your driving experience by sending you bouncing around from side to side.
The shock absorbers on each corner of your car work together with springs to cushion impacts as well as maintain body roll when cornering at high speeds or over rough terrain.
