car shakes when going over 60
A car shakes when going over 60 mph due to several mechanical issues that worsen at highway speeds. The vibration typically originates from wheels, brakes, or suspension components and requires prompt diagnosis to ensure safe driving.
Can I Drive?
You can drive to a shop for diagnosis, but avoid extended highway trips until identified. Continued driving may worsen the underlying problem and create safety hazards.
Most Likely Causes
- 1
Unbalanced or Damaged Wheels
Wheels that are out of balance cause the car shakes when going over 60 mph. Weight distribution on the wheel rim becomes uneven, creating centrifugal forces that increase with speed. This is the most common cause of high-speed vibration.
- 2
Bent or Warped Brake Rotors
Warped rotors create pulsating vibration that feels like shaking, especially noticeable above 60 mph. Rotors can warp from overheating or uneven wear, causing the brake pads to contact an uneven surface. This often affects the steering wheel and brake pedal feel.
More common in vehicles with high-performance braking or towing history

Worn Suspension Components
Damaged struts, shocks, or control arm bushings allow excessive wheel movement and cause vibration at highway speeds. As suspension components wear, they lose their ability to control wheel motion, worsening the car shakes when going over 60 condition. The shaking may feel more pronounced in turns.
- 4
Misaligned Wheels
Poor wheel alignment forces tires to work against their natural orientation, creating vibration at higher speeds. Alignment drift occurs gradually from hitting potholes or curbs. The shaking typically worsens as speed increases.
Front-wheel drive vehicles often show this symptom first

Tire Issues (Flat Spot or Bulge)
Uneven tire wear, flat-spotted areas from skidding, or internal sidewall bulges cause rhythmic shaking as the tire rotates. A flat-spotted or damaged tire presents an uneven contact patch to the road. This mimics wheel imbalance symptoms.
- 6
Engine or Transmission Problems
Misfires, worn motor mounts, or transmission issues can create vibration felt throughout the vehicle at higher speeds. Engine vibration typically worsens with acceleration and RPM increases. This is less common than wheel-related issues but should be ruled out.
Usually accompanied by check engine light or rough idle
How to Diagnose It
- 1
Visual Wheel Inspection
Jack up each wheel safely and spin it by hand, looking for visible damage, bulges, or flat spots on the tire. Check the wheel rim for bent areas or corrosion that affects balance. Look for debris embedded in the tire tread that might cause vibration.
Tool: Jack, jack stands

Brake Rotor Feel Test
Safely accelerate to 40 mph on a quiet road and gently apply the brakes, feeling for pulsation in the pedal. Listen for grinding or squealing sounds. Feel the steering wheel for vibration that pulses with the braking action, indicating rotor warping.
- 3
Suspension Bounce Test
With the vehicle off, press down firmly on each corner of the bumper and count how many times the body bounces before stopping. It should stop within 1–2 bounces. Excessive bouncing (3+ times) indicates worn shocks or struts contributing to the car shakes when going over 60.
- 4
Alignment Check
Drive slowly on a straight, flat road and release the steering wheel briefly to see if the vehicle drifts. Check if the steering wheel is centered when driving straight. Misalignment typically causes the car to pull or drift, which correlates with high-speed shaking.

Professional Wheel Balance and Diagnostics
Take the vehicle to a shop with a wheel balancer and alignment machine for definitive diagnosis. Technicians will spin each wheel on a balancer to measure imbalance weight and check alignment angles. This test identifies the exact cause of the car shakes when going over 60.
Tool: Wheel balancer, alignment machine
How to Fix It
Wheel Balance and Tire Replacement
Have all four wheels professionally balanced to redistribute weight evenly around the rim. If tires show damage or severe wear, replace them. New balanced tires often eliminate the shaking at highway speeds completely.
Brake Rotor Replacement
Remove and replace warped rotors with new OEM or quality aftermarket units. If pads are worn, replace those too to prevent premature rotor wear. This fix eliminates pulsating vibration and restores smooth braking feel.
Suspension Component Replacement
Shop recommendedReplace worn struts, shocks, or control arm bushings as identified during inspection. Suspension repairs should be done in pairs (both front or both rear) to maintain balanced handling. Proper suspension restores control and eliminates vibration at speed.
Wheel Alignment
Shop recommendedHave a shop perform a four-wheel alignment to reset camber, caster, and toe angles to manufacturer specifications. Proper alignment improves tire wear, handling, and eliminates vibration caused by wheels fighting against their direction of travel. This is essential after suspension work.
Mistakes to Avoid
- Ignoring the shaking and driving at highway speeds; vibration often indicates a safety issue that worsens with time.
- Replacing only brake pads without inspecting rotors; shaking may continue if rotors are warped.
- Balancing wheels without checking alignment; misalignment causes new imbalance to develop quickly.
