When your car vibrates every time you drive at 50-70 mph, it is most likely that your wheels are out of balance. The vibrations will emanate from the steering wheel across the seat and through the vehicle`s floor.
Tires are one of the most common causes of car vibrations. One of the possible issues are out-of-balance tires. Your problems may not be noticeable at slow speeds, but the shaking will intensify as you accelerate to 55-60 miles per hour. The steering wheel, or even the entire car, will start to vibrate.
The source of the problem could be from tires that are not balanced or a worn-out spark plug. It could also be loose lug nuts. A car also vibrates for a number of reasons when you accelerate. Typically it`s from a damaged inner CV joint.
The most common cause of vehicle shakes at 50 mph or higher is tire balance. Again, transmission or drive lines can cause this, but the tires should be the first thing to have checked.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. This shaking starts at around 50-55 miles per hour (mph). It gets worse around 60 mph but starts to get better at high speeds.
A bent axle can lead to shaking between 40-50 mph, with the vibrating increasing along with speed. On the other hand, bent driveshafts cause shaking at lower speeds, which fluctuates based on acceleration and braking. If your axle and driveshaft pass inspection, the cause might be a worn CV joint.
If your car shakes when accelerating, the source of the issue can range from imbalanced tires to worn-out spark plugs, loose lug nuts, and more. Most of these problems can be handled with a quick (but possibly pricey) trip to the mechanic.
There are a range of reasons why your car is juddering when you accelerate. Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture.
Low automatic transmission fluid can cause shaking. If the shaking is accompanied by the check engine light, it`s time to visit a mechanic. Drivers of manual cars might discover their clutch master cylinder is the source of the shaking.
Gearbox vibrations are often caused by damaged or worn out gear teeth. When gear tooth engagement involves a damaged tooth, the force cannot be transferred as with the other gear tooth engagements. If a gear tooth is broken, less force can be transferred at this point of the cycle. Vibrations occur as a result.
If you begin to feel persistent shaking in your car, it`s best that you get to the problem right away before continuing to drive. Continuing to drive with the shaking can result in further damaging parts, ruining your tires, and other costly problems that could be avoided by a quick trip to your mechanic.
Loose or damaged engine mounts may also be to blame if your car shakes when accelerating. As previously mentioned, damaged and loose engine mounts can`t efficiently absorb the vibrations produced by your cranking engine, so you`re likely to feel them when you step on the gas.
Typically vibration (shakes) are due to something that is out-of-balance. Given the tires and wheels have been balanced, it could be a wheel bearing vibration, as a worn, loose, or bad wheel bearing could cause shaking. It could also explain the noise getting louder as you accelerate.
If vibration is felt at certain speeds, the tires may need to be balanced. If the tires are wearing unevenly and causing the car to vibrate, the driver may need a tire rotation. In some cases, the driver may need new tires to solve the problem of vibration.
Wheel balance

Tyres that are out of balance will cause a vehicle to vibrate at higher speeds (usually around 50–70mph). A tyre is out of balance when one section of the tyre is heavier than another.

The most common reasons for your car to excessively vibrate are a problem with your tyres, wheels, brakes, steering, suspension, axle or engine.
If the caliper or caliper pistons become stuck, it is unable to properly squeeze the brake pads against the rotors, which may cause you to feel some vibrations when you hit the brakes.
Faster Driving (45 mph+)

Tires can get unbalanced from wear or tear, or because of more severe issues. If you think this might be your problem a normal tire rotation and balance should solve the shaking problem. Another thing that can cause shaking above 45 mph is a brake caliper that is sticking to the wheel.

The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. This shaking starts at around 50-55 miles per hour (mph). It gets worse around 60 mph but starts to get better at high speeds.
Tires. Tires are the most common reason a car shakes when it reaches 60 mph. Tire balance, or lack thereof, makes the steering shake as the car increases in speed. Typically, the shaking begins as an automobile gets to 55 mph and only becomes more problematic as the speedometer increases to 60 or more.

Typically, the shaking begins as an automobile gets to 55 mph and only becomes more problematic as the speedometer increases to 60 or more.
Driving with unbalanced tires can be dangerous and cause significant wear and tear on the vehicle`s suspension system, such as vibrations in the steering wheel and seat, poor handling and stability, uneven tire wear, and increased road noise.

Between 50 and 70 mph when I accelerate the car is shaking…. Any ideas whay ????
ANSWER : The things we check first with vibration problems are tire and wheel inspection and undercar components such as tie rod ends, rack and pinion steering, and wheel bearings. It may be as simple as a balancing weight that has come off your Jag’s wheel. I’d recommend getting some assistance from an experienced technician who can perform an inspection which will find the cause of the shaking you’re experiencing and fix it accordingly.

car shakes when idle and accelerating
ANSWER : It is very possible that you have a valve cover gasket or spark plug tube seal leak on your vehicle. These type of leaks will allow oil to leak onto the spark plugs causing misfires. When the engine misfires due to oil getting on the spark plug, the engine oil will burn. Since oil and tires are both petroleum products, they will both smell similar when they are burning. I would recommend having an oil leak inspection performed by a qualified professional to determine if there is an oil leak. Consider YourMechanic as an Oil/Fluid leak inspection can be peformed at your home or office.

My car is hesitating / jerking at speed intervals of 20 mph, 30 mph, 35 mph and 40 mph.
ANSWER : This may be a sign of a dirty or failing mass air flow sensor. The mass air flow sensor is a unit in the intake system that monitors air intake as it is mixed with fuel prior to being injected into the motor. When this fails, this can cause an imbalanced air/fuel load to be supplied to the motor which results in an over fueling or under fueling situation depending on the conditions. This may cause a hesitation, loss of power or jerking reaction when this sensor is malfunctioning. When this is not working properly, you may also notice a strong smell of fuel. I would suggest having a professional from Your Mechanic come to your home to diagnose your mass air flow sensor.

When driving my car has begin to skip and also my car shakes when i get up to about 70 mph 2010 Chevrolet Traverse
ANSWER : Hi – the shaking you are experiencing could be caused by either an out-of-balance tire/wheel assembly, bent wheel, or a failed Constant Velocity (CV) joint in your front axle. If you feel the shaking directly in the steering wheel, the problem is a front tire/wheel. If you sense shaking through "seat-of-the-pants", it could be a rear tire/wheel, or a CV joint problem. As for the misfire, check for problem codes first, whether the Check Engine light is illuminated or not. There are many possible causes for a misfire – worn spark plugs, weak ignition coil, fuel supply issue, etc. The problem code will provide guidance here. I recommend a vibration inspection to address the shake, and an engine misfiring inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose these problems, and give you an accurate assessment of damage and cost estimate for repairs.

Car begins to shake at or about 50 mph. It’s almost like a motor mount maybe broken. Could that be the issue?
ANSWER : Hello there, many faults will cause a vibration above 50MPH in your 2009 Chevrolet Malibu. It is great you have noticed the vibration is not in the steering wheel, as this rules out potential issues. The vibration is not likely due to your engine mounts, engine mounts can be felt as a jerk or clunk when the vehicle is accelerated or put into gear. Common faults that will cause a vibration are tire balance, failing tire, wheel bearings, ball joints, or suspension bushings. A qualified Technician such as one from YourMechanic will be able to diagnose your vibration issues and make any repairs required.

My car shakes when I accelerate, but stops once I let off the gas.
ANSWER : Hi there. Typically when you accelerate and the engine or steering wheel is vibrating, it’s due to motor or engine mounts being worn out. During acceleration, the motor mounts the engine vibrates naturally as RPM’s increase. Engine mounts are the component responsible for securing the engine of a vehicle to the chassis. They come in a variety of shapes and sizes to fit a wide variety of needs, but they all serve the same purpose of mounting the engine and dampening engine vibration. However, it’s also possible that a vacuum leak exists or something entirely different is causing this vibration. It’s probably best to have one of our professional mechanics come to your location to complete a steering wheel is vibrating inspection. This will allow them to isolate the source of the problem and recommend the correct repairs.

My car shakes when I accelerate above 30 mph.
ANSWER : There are many things that can potentially cause your vehicle to shake at that speed. Some of the potential causes of this issue would include but are not limited to tires with cupping wear due to bad shocks, tires are out of balance, brake rotors may be warped excessively, suspension parts may have free play or be broken, or the transmission/cv axles may have an issue. It is even possible that the engine itself may be causing this issue due to a misfire or a faulty mount of some kind.

I would recommend having a full vehicle inspection performed by a certified technician, like one from YourMechanic, paying particular attention to the tires, brakes, and suspension. Once this inspection has been performed, the mechanic will be able to give you a better idea as to what repairs will be required to resolve the issue you are experiencing.

My car starts shaking when i accelerate over 50 mph. I have had my tires balance and rotated. I put air tires and new brakes.
ANSWER : Common causes of the vibration you are describing include wheel bearing faults, wheel/tire assembly imbalance, and defective tires. Other, less common possibilities include suspension faults (strut/shock failure), loose or worn out motor mounts, and even exhaust system faults. Certain tire defects, particularly internal belt damage or separations, as well as irregular tire wear will cause vibration. Defective tires will vibrate no matter how "well" balanced they are and indeed some brand new tires with irregularities in sidewall stiffness and excessive radial force variation will vibrate no matter how well balanced. Contributing factors in the circumstance you are describing could be worn struts in the suspension. If there are flat spots on the tire tread, that would be indicative of worn struts. If you request a noise/vibration diagnostic, a certified mechanic from YourMechanic would evaluate all the possibilities and resolve this for you.
