Experiencing Car Shaking Over 60 mph can be unsettling and potentially dangerous. This vibration indicates an underlying issue that requires immediate attention to ensure your safety and prevent further damage to your vehicle. Understanding the common causes of this problem can help you diagnose the issue and take appropriate action.
Common Causes of Car Shaking Over 60 MPH
Several factors can contribute to car shaking at high speeds. Here are some of the most frequent culprits:
Tire Issues:
- Unbalanced Tires: Uneven weight distribution in a tire can cause wobbling and vibration, especially noticeable at higher speeds. Regular tire balancing is crucial.
- Wheel Alignment Problems: Misaligned wheels can lead to pulling, uneven tire wear, and shaking. Proper wheel alignment ensures your tires make consistent contact with the road.
- Worn or Damaged Tires: Tires with uneven wear, bulges, or damage can cause vibrations. Regularly inspect your tires for signs of wear and tear.
Brake System Problems:
- Warped Brake Rotors: Rotors can warp due to excessive heat or wear, causing pulsations felt through the steering wheel and car body when braking or at high speeds.
Suspension System Issues:
- Worn Shocks or Struts: These components absorb bumps and vibrations. Worn shocks or struts can lead to a bouncy ride and shaking.
- Damaged Control Arms or Ball Joints: These parts connect the wheels to the suspension system. Damage can cause instability and shaking.
Drivetrain Problems:
- Worn or Damaged CV Joints: Constant velocity (CV) joints allow for smooth power transfer to the wheels while turning. Worn CV joints can create a clicking or popping sound and vibration.
- Driveshaft Imbalance or Damage: A bent or unbalanced driveshaft can cause significant vibration at higher speeds.
Other Potential Causes:
- Loose Lug Nuts: Improperly tightened lug nuts can cause wheel wobble and shaking.
- Engine Problems: Issues like misfiring spark plugs or worn engine mounts can contribute to vibration.
Diagnosing and Fixing the Problem
While this guide provides potential causes, diagnosing the exact problem requires professional expertise. A mechanic can perform a thorough inspection, including:
- Visual Inspection: Checking tires, brakes, and suspension components for visible damage.
- Test Drive: Experiencing the shaking firsthand to assess its severity and characteristics.
- Road Force Balancing: Measuring tire uniformity and identifying hidden imbalances.
- Suspension System Check: Inspecting shocks, struts, control arms, and ball joints for wear and tear.
Conclusion
A car shaking over 60 mph should never be ignored. It signals a problem that could compromise your safety and lead to costly repairs if left unaddressed. By understanding the potential causes and seeking professional help, you can ensure a smooth and safe driving experience. Contact a qualified mechanic for a comprehensive inspection and diagnosis to resolve the issue and restore your vehicle’s performance.
