Why does my car shake at high speeds

If your car shakes at high speeds, it usually points to a mechanical or balance issue. Here are the most common causes:

1. Tire Imbalance

  • Most common cause of shaking at high speeds (especially around 55–70 mph).

  • Even a slight imbalance can cause noticeable vibration.

  • Solution: Have your tires balanced at a tire shop.

2. Wheel Alignment Issues

  • Misaligned wheels can cause vibration and uneven tire wear.

  • Usually accompanied by the car pulling to one side.

  • Solution: Get a wheel alignment check and adjustment.

3. Worn or Damaged Tires

  • Bulges, flat spots, or uneven wear patterns can cause shaking.

  • Solution: Inspect tires for damage; replace if needed.

4. Bad Suspension Components

  • Worn tie rods, ball joints, or control arm bushings can create vibration.

  • Usually includes clunking noises or poor handling.

  • Solution: Have the suspension inspected.

5. Warped Brake Rotors

  • If the shaking happens when braking at high speeds, it’s likely due to warped rotors.

  • Solution: Resurface or replace the brake rotors.

6. Driveshaft or Axle Issues

  • For rear-wheel or all-wheel drive vehicles, an imbalanced or bent driveshaft or worn CV joints can cause vibration.

  • Solution: A mechanic needs to inspect and possibly replace these parts.

7. Engine or Transmission Mounts

  • Worn mounts can cause vibration, especially under load or at certain RPMs.

  • Solution: Replace worn mounts.
