4 Reasons Why Your Car Shakes When Accelerating

If your car shakes when accelerating, read on to discover why this happens and what you need to do.


You may have experienced your car shaking when accelerating. The car may shake and vibrate while driving as a result of wear and tear and lack of routine maintenance. You should not ignore these symptoms, though, as they could potentially be caused by certain car parts. Although the shaking of the vehicle when accelerating is typically a result of the engine, this specific problem could indicate the presence of the most complicated problems.


If your automobile starts to tremble as you accelerate, that is not a good sign. It makes no difference if the noises start when you accelerate, move, or even if the car stops. There will be several vibrations, each for a distinct purpose. You can save money by identifying the source of problems as soon as possible. You can achieve this by repairing and replacing some engine components.


Why Your Car Shakes When Accelerating

Your car’s vibration could be caused by several things, from unbalanced tires to more serious engine problems. The problem may occasionally be simple, like wheel rotation. Sometimes they are more bloated, such as with steering wheel or suspension troubles. It’s critical to distinguish between moderate and dangerous vibrations.


Here are some of the reasons why your car shakes when accelerating:


Engine Problems

The engine is where most vibration issues begin. Your engine may shake or shudder at different times.


Such vibrations could be an indication that your engine needs more air, spark, or fuel. These are necessary for a smooth engine.


Signs that you need to pay attention to when your engine shakes include:

  • Car jerking when accelerating.
  • Shaking as if you’re driving fast over highway rumble strips.
  • The car handles well, but after a while, it begins to shake.


You should check your spark plugs as soon as the aforementioned symptoms appear. While you’re at it, thoroughly inspect the order in which the spark plug wires connect. The spark plugs or wires might need to be replaced.


The condition of your engine oil could also be a contributing factor to engine shake. Your engine will run out of fuel or oxygen if the oil filter or the air filter is dirty or clogged.


Filters are inexpensive, and changing them is not difficult. To make sure you change them on schedule, follow the manufacturer’s recommendations.

Axle Problems

There are a lot of rotating components in vehicles. Within predetermined limits and tolerances, each of these components must operate at peak efficiency.


Simple impacts can easily bend an axle. Your axle may cause your automobile to sway when this occurs. When you accelerate, the vibrations will likewise become more intense.


The driveshaft can be another connected problem. In rear-wheel-drive automobiles, it is the component that spins quickly to transmit power from the engine to the back axles.


You should inspect them for bends. If so, that might be the cause of the vibrations you feel while your car accelerates.


The constant velocity joints can present an issue occasionally. On the ends of the driving axles, some coverings resemble boots.


They are only complete when the rubber is in good condition, the clamps are tight, and no lubricant is leaking out. All the road debris will go inside the joints if the boots are destroyed, which will harm the moving parts.


If your vehicle has front-wheel drive, damaged CV joints require that you repair both of the axles.


Faulty Tire Balance

First off, improperly balanced or repaired tires might cause your car to shake when you accelerate. This typically occurs when you purchase new tires. Tires never have the same mass all the way around when they are installed on the wheel. Any weight imbalance will manifest as a small vibration when a tire rotates.


The shaking will be more noticeable and your steering wheel will shake at much greater speeds where the tire is rotating considerably faster. You may have an imbalanced tire if your car vibrates continuously and worsens at higher speeds. Another possibility is that one of the wheel weights fell.

Defective Motor Mounts

The main job of motor mounts is to fasten an automobile’s engine to its frame. A secondary goal is to reduce engine shaking so that the car’s owners won’t notice the engine trembling constantly when it’s on. Because engine mounts are composed of firm rubber, they can absorb the shaking.


In addition to the car shaking a lot, damaged motor mounts can cause other engine components to become out of alignment and finally break because the engine is no longer in its proper place. While the car is idling, you can see that the motor mounts aren’t working properly, but the shaking is more noticeable while the car is accelerating.


Are These Problems Serious?

You may cause an accident that harms you or someone else on the road if you choose to continue driving and disregard the problems we described above. Even a tire that is out of balance can endanger your safety and make driving at highway speeds more difficult.


What Will It Cost to Fix the Vibration?

If you’re lucky, the vibration you feel will only be a minor inconvenience, such as a tire that has to be balanced. If your tire store offers additional services for goods you buy there, you might be able to get out of these situations for little to nothing. Remember that these costs are approximations based on average costs. Use this merely as a starting point because your experience can be very different.


Wrapping Up

With routine maintenance, your car will continue to run more efficiently. It will solve all kinds of auto problems. Make sure your car is well-maintained to replace worn-out parts. Ensure you repair these components before they harm your car’s engine.


You can solve most of them by yourself. However, some problems can only be solved with expert assistance. If you don’t know how to replace damaged parts, you could end up doing more harm to the car.


It’s important to figure out what’s wrong and take the appropriate action if your car shakes when accelerating. If you don’t, you could get into an accident or have to pay a lot of money to replace the part or even the whole engine.
