How Come There is a Vibration from My Gas Pedal When I Accelerate?

In recent decades, car manufacturers have slowly but surely transitioned from using heavy materials for creating their car parts to more lightweight materials, such as polymer matrix composites to reduce vehicle fuel consumption.

While it’s true that this shift has significantly reduced fuel consumption in modern cars, it’s also had an adverse effect where car parts are becoming more fragile, which is true of both OEM parts and aftermarket parts.

Another big factor is road quality. Currently, the US sits at the 17th spot in terms of road quality worldwide. Driving on deteriorated roads is one of the main causes of vehicle degradation and vibration, with some of the first victims being the following car parts.

What are the Usual Causes of Car Vibration?

The following things might be the reasons why you’re experiencing vehicle vibrations, shaking, and other inconveniences.

CV Join Issues

The CV joints are part of your car’s axel system. As far as car parts go, they’re quite resilient. Still, it isn’t unheard of for a CV joint to malfunction occasionally. This usually happens whenever the rubbery parts get loose, which may lead to vibrations in the affected axel.

Damaged Driveshaft or Axles

A malfunctioning driveshaft is particularly troublesome if you have a rear-wheel drive vehicle that requires power to be sent through the driveshaft to propel the vehicle forward. The damage can either be a bend or a misalignment, both of which will cause vibrations.
Damaged axles are another reason why you might be experiencing vibrations. A damaged axle makes your car feel like it’s constantly bouncing on one side, which is an inconvenience at best and a hazard at worst.

Unbalanced Tires

If you’ve recently had work done on your wheels and are experiencing vibrations, it’s most likely the result of an unbalanced tire or two. Thankfully, this is easy to fix with a little pit stop time.

Malfunctioning Brake Clippers

A malfunctioning brake clipper may sometimes apply pressure to your wheels even when you’re not pressing the brakes, which may cause vibrations. If this is the case, then vibrations are the least of your concern.
Driving with malfunctioning brakes is one of the leading causes of traffic incidents. If you suspect your brakes are damaged in any sort of way, contact A Plus Auto Parts for a replacement ASAP to avoid any accidents.

Degraded Input Shaft Bearing

Input shaft bearing degradation is a nasty little defect that can often cause vibrations in your gas pedal as well as a droning sound. To diagnose this defect, simply put your vehicle in neutral to see if the vibrations stop. If they do, then it’s definitely a busted input shaft bearing.

Loose Lug Nuts

You checked all the other car parts, but the vibrations remain. Why is that? Well, the problem might be in your lug nuts. Loose lug nuts are known to cause slight vibrations. Thankfully, they can easily be fixed with a lug wrench and a couple of minutes of your time.

Faulty Spark Plugs

Spark plugs rarely go out, but whenever they do, they’re known to cause nasty engine misfires, which tend to rattle the entire car. That’s why it’s a smart idea to replace them every 30k miles or so to ensure that never happens.

Loose Motor Mounts

Motor mounts are the thing that holds your motor in place. With time, these might get loose, leading to some vibration. The changes are subtle, which is why most drivers don’t pick it up right away.
Unlike other car parts, you probably won’t be able to fix this problem by yourself unless you have some know-how and the right equipment. If the vibrations become too unbearable, take your car into the shop for a quick tune-up.

Some Tips to Avoid Car Vibrations

Most of these issues can be avoided with frequent maintenance and a little more care when driving your vehicle. Make sure to employ the following tips when driving, and you should be just fine.

Refrain from Flooring the Throttle

Most of us like to think, “I paid for the entire speedometer, so I’m gonna use the entire speedometer.” But that’s actually one of the worst things that you can do. Driving your vehicle at full throttle will only degrade your car parts faster and nothing else. Because of the laws of physics, the faster you’re going, the more vibrations you’ll experience whenever you make a slight deviation. Just stick to an appropriate speed – it’s safer for you, your vehicle, and any pedestrians walking on the road.

Perform Regular Maintenance

Are you thinking, “She’s got a couple more months in her?” It is the worst thing you can think about your car whenever you start noticing anomalies. What started as a strange noise or slight vibration may lead to complete engine failure later on down the line. That’s why taking your car in for a check-up every year is so important. Although time-consuming, annual maintenance can save you hundreds, if not thousands, of dollars.

Clean Your Vehicle Regularly

It costs 0 dollars to clean your vehicle. However, it can save you hundreds of dollars in maintenance fees by doing so. Pay special attention to the areas around your pedals and the shift stick if you’re driving a manual. Don’t forget the outside of your car, too. Make sure to clean your wheel well often, especially after a muddy season, as that’s how dirt and grime get into your axles.

Avoid Bumps & Holes

As we mentioned previously, poor roads are one of the main reasons for vehicle degradation. Particularly nasty bumps may even cause long-lasting damage to your vehicle, like a bent component or a misaligned axle. If your vehicle is not set up for off-road travel, steer clear of any dilapidated roads you come across.
