Car Shaking At 60-80 MPH? 5 Most-Common Reasons (Solved)

Driving at higher speeds can be a smooth and comfortable experience, but when your car starts shaking between 60 and 80 mph, it’s a cause for concern.

This article will discuss the possible reasons behind this issue, providing valuable insight for those facing this problem.

By understanding these reasons, you’ll be better equipped to take the necessary steps to address and fix the issue.

Common Causes of Shaking between 60-80 mph

Diagnosing the cause of your car’s shake can be a complex task, but our aim is to make it easier by identifying common factors contributing to the vibrations at high speeds.

Cars shouldn’t shake – even at high speeds.

Let’s start with the most common reasons.

Unbalanced Wheels

A common cause of car shaking between 60 and 80 mph is unbalanced wheels.

When the tires are not properly balanced, the car may experience significant vibrations due to uneven weight distribution across the wheels. Inspecting the wheels and addressing any balance issues can help restore a smooth ride.

Worn Out Tires

Worn out tires can contribute to a shaky vehicle at higher speeds.

tire crack (dry rotting)

As tires wear down, their surface becomes uneven, and this can affect the way they come into contact with the road.

When this occurs, the car may shake when traveling between 60 and 80 mph. Regular tire maintenance and replacements can prevent this issue.

Damaged Suspension

A damaged vehicle suspension system can also cause shaking between 60 and 80 mph.

The suspension helps to manage the car’s weight and supports the vehicle as it travels over uneven surfaces. If any components within the suspension are damaged or worn out, it can result in shaking at higher speeds. A thorough inspection of the suspension system can help identify and address any possible issues.

Loose Wheel Bearings

Loose wheel bearings are another possible factor with a car shaking at higher speeds.

Wheel bearings are responsible for allowing the wheels to rotate smoothly. If they become loose, they can contribute to the unsettling vibrations experienced when driving. Diagnosing wheel bearing issues can involve checking for play while the car is raised and attempting to move the wheels by hand.

Faulty or Worn-Out Drivetrain Components

Lastly, faulty or worn-out drivetrain components can lead to a shaky ride around 60 MPH. The drivetrain is responsible for connecting the engine to the wheels and facilitating smooth power transfer.

Any damaged or worn-out parts within the drivetrain can contribute to shaking at higher speeds.

My car is shaking when I use the brakes

Sometimes, it’s especially during braking the shaking occurs. I’ve had this issue myself, and it was due to uneven breaking.

Brake problems, like warped brake rotors

One common cause of car shaking when braking is warped or damaged brake rotors. Brake rotors are the large metal discs between the brake pads on each wheel.

Over time, they may become worn, rusty, or damaged, leading to an uneven application of the brake pads, causing the car to shake while braking.

Some possible reasons for warped or damaged brake rotors include:

  • Excessive heat from aggressive braking
  • Rust from exposure to moisture
  • Uneven wear due to poor brake pad quality or irregular pad replacement

To resolve this issue, it is recommended to have a certified mechanic inspect the brake rotors and replace them if necessary.

Issues with the steering system

Another potential reason for a car shaking when braking is problems with the steering system. Some components that can contribute to shaking include:

  • Unbalanced or misaligned wheels: Wheels that are improperly balanced or misaligned can cause uneven pressure on the tires while braking, leading to shaking.

  • Suspension problems: Damaged or worn suspension components, such as ball joints or tie rod ends, can cause irregular movement and vibrations during braking.
  • Worn brake pads or shoes: Uneven wear on brake pads or shoes can also lead to an unsteady braking experience, causing the car to shake.

Here is a table summarizing some issues within the steering system and their potential solutions:

Issue Solution
Unbalanced or misaligned wheels Rebalance or align wheels
Suspension problems Inspect and replace damaged components
Worn brake pads or shoes Replace brake pads or shoes

To address steering system issues, consult with a qualified mechanic to diagnose and repair any problems.

By maintaining your car’s braking and steering systems, you can help prevent shaking and ensure a safer and more enjoyable driving experience.

Inspecting Your Vehicle

Checking Tire Inflation

Proper tire inflation is essential for a smooth and safe ride.

To check your tire inflation, use a tire pressure gauge and compare the readings with the manufacturer’s recommended psi (pounds per square inch) levels. These recommendations can usually be found in the vehicle’s owner’s manual or on a placard inside the driver’s door jamb.

Maintaining proper tire inflation can help prevent vibrations at higher speeds, and it also promotes even tire wear and improved fuel efficiency.

Rotating and Balancing Tires Regularly

Rotating and balancing your tires helps ensure even wear and extends their lifespan.

Regular tire rotations can prevent uneven wear patterns that cause vibrations at high speeds. It is generally advisable to rotate your tires every 5,000 to 8,000 miles or as specified by the vehicle manufacturer.

Balancing tires requires a professional to examine them on a balancing machine, ensuring that the tire weight is evenly distributed. This process can significantly reduce vibrations while driving at high speeds.

Examining Suspension Components

The suspension system plays a crucial role in ensuring a comfortable and stable ride.

Worn or damaged suspension components, such as shocks and struts, can cause vibrations while driving between 60 and 80 mph.

Inspect the suspension system for signs of wear, such as leaking fluids or damaged bushings, and consult a professional mechanic if any issues are detected.

Regular suspension inspections and timely replacements of worn parts can help prevent vibrations and ensure a smooth drive.

Assessing Wheel Bearings

Faulty wheel bearings can cause vibrations while driving at high speeds.

To assess the wheel bearings, safely lift the vehicle off the ground and attempt to move the wheel by hand. There should be minimal play in the wheel, and if it feels loose, the bearing may be the culprit.

If you notice vibrations while turning or lane-changing, it’s a good idea to have the wheel bearings checked by a professional. Inefficient wheel bearings should be replaced promptly to promote a smooth and safe ride.
