Common Causes of Steering Wheel Vibration at 100 to 120 km/h

Experience a steering wheel vibration or shaking between 100 to 120 km/h? While the sensation can be alarming, it is important to identify the root cause to ensure a smooth and safe driving experience. This article explores the common causes and solutions for this specific issue.

Wheel Imbalance

Improperly balanced wheels can lead to vibrations at certain speeds. This is one of the most common causes, and it can often be resolved by having the wheels balanced. When the wheel weights are not evenly distributed, the rotation of the wheel creates a knocking or shaking sensation, especially at specific speeds. Regular wheel balancing ensures that your vehicle runs smoothly and reduces this vibration.

Tire Issues

Tire Wear

Uneven or excessive tire wear can also create vibrations. Check for bald spots, cupping, or other irregular wear patterns. These can be felt as vibrations through the steering wheel. Regular tire rotation and proper alignment help distribute wear evenly, reducing the risk of vibrations.

Tire Pressure

Incorrect tire pressure, either too high or too low, can cause vibrations. Always ensure your tires are inflated to the manufacturer’s recommended levels to maintain optimal vehicle performance. Proper inflation is crucial for a smooth ride and to prevent unnecessary vibrations.

Defective Tires

A defective tire, such as one with a bulge or internal damage, can cause shaking. If you notice any unusual symptoms in your tires, have them inspected promptly to ensure safety and prevent further issues.

Alignment Problems

Misalignment can lead to uneven tire wear and vibrations. If your vehicle pulls to one side or if the steering wheel is off-center, alignment may need adjustment. Proper alignment ensures that all wheels are in proper position, reducing wear and tear and minimizing vibrations.

Suspension Issues

Worn or damaged suspension components like struts, shocks, or bushings can cause vibrations, particularly at higher speeds. Suspensions are responsible for absorbing shocks and maintaining a smooth ride. If any of these parts are malfunctioning, it can cause a noticeable vibration through the steering wheel.

Brake Issues

While brake vibrations at low speeds are common, they can also occur at high speeds due to warped brake rotors. Warped rotors can cause vibrations when the brakes are applied, but they can also lead to vibrations at higher speeds due to uneven contact with the brake pads.

Wheel Bearings

Worn or damaged wheel bearings can cause vibrations that may be more pronounced at certain speeds. Wheel bearings support the wheel and ensure smooth rotation. If they are not functioning properly, it can lead to a noticeable vibration through the steering wheel.

Drivetrain Problems

Issues with the drivetrain, such as a damaged driveshaft or CV joints, can result in vibrations at specific speed ranges. The drivetrain transmits power from the engine to the wheels, and any malfunction can cause vibrations and other issues.

Engine or Transmission Mounts

Worn or broken mounts can lead to vibrations being transmitted through the steering system, particularly at higher speeds. Engine and transmission mounts are designed to isolate vibrations, and if they are not functioning correctly, it can affect the overall driving experience.

To resolve steering wheel vibrations or shaking, it is advisable to have the vehicle inspected by a qualified mechanic. This will allow for accurate diagnosis and appropriate solutions to prevent further issues and ensure a safe and comfortable driving experience.

Remember, if vibrations persist, take your vehicle in for a professional inspection. If it is a car you are considering purchasing, take it back and leave it if the issue is unresolved. This can save you from endless repair bills.
