Q: My Car Is Shaking When Idling But It Does Not Vibrate While Driving Or Moving Does This Mean That There Is Nothing Wrong With It

Can transmission cause car to shake?

A: Not necessarily. Even though your car vibrates when you are moving, this doesn’t rule out a problem with your engine. If you have never had an engine fault code check performed or any work done on your front-end assembly, getting these services may be necessary to pinpoint the root of the issue with your car shaking when idling.

Loose Or Bad Wheel Bearing

Loose or worn wheel bearings and loose steering components are closely linked and have similar symptoms. The wheel bearings are mounted on the steering hub and allow the wheels to rotate freely.

If these bearings wear out, the wheel can move freely from side to side at any speed, causing disturbing vibrations.

You will often also hear a high noise while driving at a higher speed when your car suffers from a bad wheel bearing.

Worn Suspension Parts And Joints

Looseness in suspension or steering system components can cause your steering wheel to shake. Excessively worn ball joints or tie rod ends make it impossible to properly align your vehicle. Take your vehicle to a mechanic and have them inspect your ball joints and other components to help identify what is causing your steering wheel to shake.

    No : Worn Or Bent Parts

    The brake rotor isnt the only part that can wear out and cause your vehicle to shake. And, if youve been in an accident, your car could have a bent axle that makes your vehicle vibrate as you drive.

    A bent driveshaft and worn-out CV, or constant velocity, joints also could lead to making your car shake when youre driving.

    Your Tires Are Out Of Balance

    Ifyour tires need to be balanced, you might not even notice the vibratinguntil you get to about 55 MPH or so. While it’s possible for the entirecar to shake with this issue, it’s also possible for it to be localizedin the steering wheel. If the vibrating is a result of a tire imbalance, your tire would be exhibiting unusual wear and tear in the form of several flat spots. A simple balancing will stop the uneven wearfrom continuing as well as the shaking.

    Bad Mass Air Flow Sensor

    Can a bad alignment cause shaking?

    A bad mass airflow sensor can cause your vehicle to run rough while idling or accelerating. The mass airflow sensor is responsible for calculating the best air/fuel ratio for the engine to run efficiently.

    If your mass airflow sensor is bad your air/fuel ratio will not be balanced. An unbalanced air/fuel ratio causes your vehicle to run lean or rich and misfire under a load. The driveable of your vehicle is difficult and rough while your air/fuel mixture is unbalanced.

    Signs Of A Bad Mass Air Sensor

    • The engine will run rich or Lean
    • Hard to start
    • The engine will stall out
    • Jerking and hesitating

    A Bent Axle May Be At Fault

    If your car started shaking after an accident, or some other mishap like running over a large pothole or hitting a curb, you might have bent an axle.

    If you do not know already, an axle delivers power directly from the transmission to the wheel. It is basically a shaft connecting these two parts, that rotates with the wheels. If you do have a bent axle, youll usually notice the shaking intensifies as you accelerate.

    Repairing or replacing an axle can be costly, from as low as $170 to as much as $900. It all depends on the extent of the damage and whether a repair is even possible. The make and model of your car also influence the cost.

    If its more than a shake, you might want to stop driving altogether until its fixed. Otherwise, you may wreak havoc on the rest of your suspension system, which can become expensive rather quickly. If the shake is minor, you should be ok driving for at least a little while.

    Why Does My Car Shake When At Idle

    Rough idle is a symptom of a problem within your vehicle that you shouldnt ignore, as it may indicate a serious underlying issue. If your car shakes at idle, take it to a certified mechanic, like the ones at our Honda dealership, for diagnosis and correction.

    Here are some of the common reasons for rough idle:

  • Motor mounts: Its the job of the motor and transmission mounts to dampen vibration. When they break, youll feel excessive vibration, especially at idle. You can diagnose this yourself by putting your car in neutral. If the shaking lessens, you very well could have broken mounts. A professional mechanic can quickly confirm this.
  • Timing belt: The timing belt choreographs the actions of several components and accessories. A stretched, torn or worn-out belt will result in inconsistent timing, which causes shaking. This most often occurs in high-mileage vehicles. If you start seeing cracks, ribbing or looseness in any of your belts, have them replaced right away.
  • Fuel intake: Engines dont like dirt, and thats especially true of the fuel injectors and intake valves. If they become befouled by dirt or debris, they will deliver uneven amounts of fuel with each engine cycle, causing a high-frequency shutter or shake. A technician can clean out the dirt, and you can often avoid the problem by using quality fuel and perhaps additives that clean the fuel intake system.

    Low Profile Or Low Rolling Resistance Tires

    causes of engine vibration

    Tires are often the cause of your car’s moving vibrations, so the next two pages will examine different tire problems and how they can affect the way your car runs.

    Low rolling resistance tires, also known as low-profile tires, are becoming increasingly common along with the rise in hybrid cars and EVs. These tires reduce drag and resistance, which in turn boosts the EPA fuel economy rating, a critical measure for these types of vehicles, particularly from a marketing standpoint. However, low rolling resistance tires are harder than most drivers are used to, and simply aren’t pleasant to drive on because they don’t absorb much of the road’s imperfections.

    Even though they’re also referred to as low-profile tires, that term can be confusing because the “low profile” may also be attributed to other performance tires. In either case, you’re looking at tires that have less material, or harder material, and therefore tires that are less able to absorb bumps, pits and texture on the road.

    If your car is equipped with low-profile or high-performance tires, that could be the source of your vibration problem. However, it’s best to eliminate other potential causes.

    You May Have Engine Issues

    There are several components under the hood of your car that can cause it to vibrate while idling or accelerating.

    The first is bad spark plugs, which are in charge of igniting the air/fuel mixture inside each combustion chamber. If any of them are worn, it can interfere with them firing correctly. When an engine misfires, it can cause a shake with each cycle.

    A shake doesnt explicitly suggest faulty spark plugs, since, before air or fuel reach them, they each pass through their own filter. If your air filter or fuel filter is clogged, the spark plugs wont receive enough of either to function. This can also cause a misfire, and thus a shake.

    You might also have worn motor mounts. If you didnt know, the engine is secured directly to the chassis of your car by motor mounts. Thankfully, they usually last for between 5-7 years. Beyond this, they may weaken, which might lead to a noticeable vibration.

    The good news is that spark plugs and fuel or air filters are cheap to replace. Motor mounts, on the other hand, range from about $200 to nearly $600.

    Can Transmission Cause Car To Shake

    Yes. If the car shakes only when the transmission is in drive, you may have a bad torque converter that needs to be rebuilt or replaced. Several components may cause a shaking movement in your vehicle.

    These include the brake, tire and wheel assemblies, and a control arm. In addition, the transmission could also be causing a shaking movement in your vehicle.

    Any shifting issues, along with worn-out engine mounts or loose drivetrain components, can result in excessive shaking felt while driving or stopped at idle.

    If your car starts shaking and jerking when you press down on the accelerator, or if starts to feel like youre driving over a rumble strip when you hit certain speeds, it could be time to check the spark plugs. Spark plugs make a big difference in how smoothly your car operates, and if your engine isnt getting a sufficient amount of spark, youre going to feel it. Faulty spark plugs can also contribute to a phenomenon known as “rough idle” which can also cause your vehicle to shake.

    Even if the spark plugs themselves arent the problem, have the spark plug wires checked to see if theyre properly connected or if they need replacing.

    Air Intake Hose Disconnection

    Another common reason your car may shake when idle is due to an air intake hose disconnecting under the hood. This often causes similar symptoms as a loose engine mount since it will affect the engine’s position.

    The air intake hose typically connects to the big metal tube from your air filter box and sticks into your engine. If this hose becomes disconnected, you will notice increased vibrations when idling.

    A loose clamp often causes this on one side or another, which can also cause damage to your car’s other components over time if not dealt with immediately.

    The solution: depending on where the air intake hose is disconnected, you may need to tighten both clamps on either end to reconnect it properly. If the connection was at the other end , you should also inspect for any cracks or dents to ensure no damage was done to the pipe itself.

    If Your Vehicle Is Shaking It’s Not Just An Irritating Nuisance It Means There’s Likely Something Wrong With Your Car

    Vehicles shaking or vibrating while accelerating, driving down the highway, braking or idling are among the most frustrating and common automotive complaints. A shaking car is scary, especially if you dont know why its shaking. Understanding and recognizing the causes and what you can do to fix it are critical to your safety and the overall health of your car.

    Dirty Or Worn Spark Plugs

    Spark plugs that are dirty or fouled up can cause the engine to misfire. While the problem is usually first noticed when at a stop, it may also make it seem like the car is vibrating when driving.

    If you dont remember the last time you replaced your spark plugs, it may be time to do so. If you remove one and notice a bunch of dark buildup on the tip, theres good chance the rest of your spark plugs are bad as well.

    Hoses Are Loose Or Disconnected

    Clunking Noise When Braking

    Those of you dont know what houses are in your car. The hoses are the cooling systems weakest structural component, and hoses are made of flexible rubber.

    For many reasons, your cars hoses can be loose or disconnected from the engine mount. When hoses are disconnected from the mount, the car shudders when AC is on.

    Whenever you inspect hoses that are loose or disconnected, you should tighten the loose hoses.

    If you see hoses disconnected, connect back to the mount and fix your BMW shakes when AC is on the issue.

    Vibration Through Gas Pedal Or Seat

    Letâs say you only notice a vibration through the back of the seat, the gas pedal, the floorboard or maybe the seatâs bottom cushion itself. If thatâs the case, thereâs a good chance that itâs coming from the vehicleâs drivetrain.

    A vibration through the gas pedal is common on a front-wheel-drive vehicle that has CV joints that are starting to wear and fail you might also notice a clicking or ratcheting sound while rounding a corner, or feel a distinct âclunkâ when you step on or let off of the gas pedal. On a rear-wheel-drive car, a vibration through the floorboard can mean a driveshaft thatâs out of balance or a U-joint thatâs starting to wear, allowing slop in the driveline and the same âclunkâ you might notice on a FWD vehicle.

    Other causes for this kind of vibration can include exhaust system mounting problems, exhaust leaks or emission control issues.

    Regardless of whether your vehicle is RWD or FWD, youâll want to get any of these kinds of issues looked at promptly because, once again, they donât just get better on their own.
