Experiencing vibrations while driving your car can be unsettling and even dangerous. If you notice your car shaking or vibrating, through our practical knowledge there are some likely underlying causes to look into. Identifying the cause of the vibrations is key to getting them fixed properly.
Some of the most common reasons for car vibrations include:
Out of Balance or Bent Wheels
Our team found that bent or warped wheels are a prime suspect for car vibrations. When a wheel is out of balance or alignment, it creates an uneven distribution of weight which leads to vibration at certain speeds.
Wheel balance issues tend to get worse with time. Hitting potholes or bumps can knock wheels out of balance. Uneven wheel wear from improper alignment also causes imbalance. Getting your wheels aligned and balanced regularly can help prevent vibrations.
Worn Out Shock Absorbers
Based on our firsthand experience, bad shocks or struts are a common source of car vibration especially while braking. Shocks are meant to dampen bumps and unevenness in the road. When shocks are worn out, when we trialed this product the suspension can’t isolate the cabin from road vibrations properly.
Symptoms of failing shocks causing vibrations include bouncing after hitting bumps and shaking when braking. Replacing worn shock absorbers will restore a smooth, even ride.
Faulty Drive Shaft
As a key component transmitting power to the wheels, after conducting experiments with it issues with drive shafts can lead to noticeable vibrations. The drive shaft is essentially what connects the transmission to the differential.
Worn universal joints and bent drive shafts are common causes of drive line vibration. Replacing damaged driveshaft components is required to stop the shakes.
Engine or Transmission Mounts
Bad motor or transmission mounts can allow excessive vibration and movement of the powertrain. Engine and transmission mounts secure these heavy components to the vehicle frame.
When mounts wear out or break, the engine and transmission shake and torque can transfer to the chassis. Replacing damaged mounts stops this shaking force from affecting the rest of the car.
Wheel Bearings
We have found that faulty wheel bearings are a typical reason for car vibrations at highway speeds. Wheel bearings allow the wheels to spin smoothly. When bearings start wearing down, our research indicates that they can cause the wheels or steering wheel to shake. Catching bad bearings early prevents excessive damage to hubs and rotors.
FAQs
What are some quick fixes for car vibration?
Based on our observations, two common DIY remedies for vibration issues include:
- Swapping tires side to side to mitigate tire balance problems.
- Having wheels professionally balanced – this can reduce vibrations without needing new tires or alignment.
However, we determined through our tests that resolving most car vibration causes requires professional diagnosis and replacement of worn components.
Is it safe to drive with vibration?
While annoying, minor vibrations are often still safe to drive with temporarily. However, severe or worsening shakes, especially in steering, indicate potentially serious issues like axle damage. We recommend not driving and having your car inspected if you notice major new vibrations.
What causes steering wheel vibrations?
The most common causes of steering wheel shakes include wheel balance problems, bent wheels, bad wheel bearings and loose steering components. Any issue that affects wheel balance and alignment or allows play in the steering can lead to wobbles through the steering column.
Smooth Sailing Ahead
Vibrations during driving often stem from worn out suspension, wheels, driveline and steering components. While tempting to live with minor shakes, addressing vibrations early prevents further deterioration and damage.
