A number of components can cause vibrations. first thing to check is the tires and wheels. Improper wheel balance can cause vibrations at certain speeds. The tires and wheels should also be checked for run out – side to side movement. A shifted belt in one of the tires or a bent wheel can cause vibrations. Loose or worn suspension components such as tie rods or ball joints can also contribute to vibrations. If the condition of the wheels and tires are within specs, have a certified technician inspect the suspension for loose/worn components.

Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
Tire issues: The most frequent causes of a vehicle shaking while driving stem from tire issues. Tires begin to behave differently when worn or out of balance. Tire replacement, realignment, and rebalancing are common solutions.
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.
Worn suspension or steering system components can come loose and begin to shake or vibrate as you drive. And if you find your vehicle shakes particularly when accelerating hard or at highway speeds, that can even be caused by a worn rear suspension.
If your vehicle vibrates when accelerating, some most likely causes include a faulty braking system, imbalanced tires, a bent axle, or misfiring spark plugs. If the vibrations get even worse every time you accelerate, a bent axle is the main culprit.
The only fix is to completely replace the CV joint. The main purpose of motor mounts is to attach a car`s engine to the frame of the vehicle. A secondary purpose is to dampen or reduce engine vibration so the occupants of the car don`t feel the constant shaking or vibrating of the engine while it`s running.
Some simple warning signs that the transmission is having problems: Transmission is slow to respond when shifting. Grinding, shaking, vibrating.
Installing new spark plugs is the best way to resolve such vibration related issues. The timing belt ensures the accurate functioning of many critical components of the engine. Any issues with the timing belt can cause your car`s engine to vibrate.
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.
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.
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.
As you get into the higher speeds, if you distinctly feel vibrating coming from the engine, this could be a result of a lack of power, fuel, or oxygen getting to it. The spark plugs, fuel filter, and air filter should all be checked and replaced as needed.
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 likely cause of the shuddering most often happens in the vicinity of your car`s rims and tires. They plant your car to the road, and if anything is broken, will feel it. On a serious note, it may be a broken transmission mount or a broken caliper.
Vibration when 65+mph or when stoping
Whenever there are multiple causes of vehicle vibration, which is probably the circumstance you face, it is best to fix the obvious causes first because that will greatly simplify diagnosis and identification of the remaining causes. So, in your circumstance, you should request replacement of the motor mounts and then continue on with the vibration diagnostic. If you do end up replacing motor mounts, genuine OEM mounts are recommended in order to maximize the chances of resolving that portion of the vibration problem. If the vibration at idle, during parking, is not resolved by replacing the motor mounts, be sure to rule out engine operating conditions. For example, rough running at idle can be caused by faults in the air induction system as well as the ignition and fuel systems. To get an evaluation of the running condition of the engine, please request a rough idle diagnostic.
Vibration at high vehicle speeds, felt through the car body and/or the steering wheel, is usually due to dynamic imbalance of the wheel/tire assembly and/or various types of tire defects such as belt separations or excessive radial force variation. Vibration on braking is typically due to excessive thickness variation in the brake rotor, pad defects, or excessive rotor runout as installed on the hub. Typically, thickness variation can’t exceed .001 inches and rotor runout, as installed, should ideally be no more than .002 inches. To determine if the rotors are the cause of the vibration in your case, rotor runout has to be carefully measured. To have the root cause of the brake vibration identified, please request a brake and suspension system diagnostic.
