Posted: Tue Mar 05, 2024 11:01 am
Nothing ensures a driver more than a firm and well-balanced car, especially at high speeds. So, it can be worrying when your vehicle starts shaking and bouncing while driving down the road. Have you recently started wondering "Why Does My Car Shake"? Well then, you have come to the right place.
Car Shakes When Braking
There are many reasons why a car might start shaking. It can happen due to an engine issue, faulty suspension, or something else entirely. Continuing to drive your vehicle while it is in this condition is just a disaster waiting to happen.
Having a clear understanding of the sources of the issue will go a long way in helping you perform the necessary repairs. Let's dive into some common reasons why your car might shake when you apply the brakes.
1. Sticky Calipers
When you push the brake pedal, you expect it to be firm and reassuring. However, this is not the case every time. One occasion where many drivers find themselves wondering "why does my car shake" is when they press the brake pedal.
2. Dry Guide Pins
The brake calipers of your vehicle come equipped from the factory with two caliper guide pins. These take the form of round metal pins, and they make sure that the brake pads meet the brake rotor at the correct angle.
3. Tire Imbalance
Out-of-balance tires are another common issue that makes drivers wonder "why does my car shake?" when they hit the anchors.
4. Worn Brake Rotors
Brake rotors are one of the most crucial parts of your braking system. These take the shape of large metal disks and attach to the hub assembly of each wheel.
5. Deformed Brake Drums
Although most modern cars have disk brakes on all four corners, there are still a significant number of vehicles with rear drum brakes driving around our roads.
6. Suspension Issues
One of the primary reasons for your car shaking is issues with the suspension system. The suspension system is made up of several components, so there are plenty of things that could go wrong.
7. Overloading
Sometimes, the reason behind your car shaking might be simply due to you having too much weight inside or on it.
8. Low-Quality Tires
Nowadays, there are hundreds of different tire brands you can choose from. Some come from well-reputed and recognizable brands that have been in the business for generations.
9. Road Conditions
On some occasions, your car might start shaking while braking even when there isn’t anything mechanically wrong. In this case, the most probable cause is rough road conditions.
Car Shakes When Accelerating
Although most issues that cause a car to shake when accelerating are minor, there are still cases where it may be an indication of something more severe. Here are a few of the most common culprits that make your car vibrate when you put your pedal to the metal.
1. Loose Lug Nuts
Similar to braking, the lug nuts can cause shaking during acceleration too.
2. Axle Damage
Bent axles are another cause that makes a car shake when accelerating.
3. Bent Driveshaft
The same goes for bent driveshafts too.
4. Damaged Motor Mounts
Have you ever wondered what keeps the engine attached to the frame of your vehicle? Well, the answer is the motor mount.
5. Issues With The CV Joints
The final problem which may cause your car to start shaking under acceleration is a damaged CV joint.
No matter the cause, it is important to apply the necessary fixes as soon as possible. Continuing to drive the vehicle in a damaged state may end up getting you in catastrophic accidents.
