17 June 2025 (updated) Why is the steering wheel shaking?
Does your car’s steering wheel shake and at higher speeds the vibration is clearly stronger? Then you probably don't have a problem with the steering, strictly speaking. The issue most likely lies elsewhere as there are many possible causes of car vibrations. Here, we will investigate the most common causes of a shaking steering wheel and what to do to get your car fully "under control" again.
Top causes of a shaking steering wheel
1. Unbalanced wheels
One of the major causes of steering wheel vibrations is unbalanced wheels. When the distribution of mass around the tyre and wheel assembly isn’t even, it creates centrifugal forces that cause the steering wheel to wobble, typically more noticeably at speeds of 70 mph or above. However, at very high speeds, the vibrations might even lessen again due to resonance effects.
2. Uneven tyre wear
Tyres that are worn unevenly, due to overinflation, underinflation, or poor alignment, can also lead to a vibrating steering wheel. In this case, it is easier to detect when the vehicle is accelerating or cruising at moderate speed. Sometimes uneven tread wear is caused by misalignment or suspension issues.
3. Loose or damaged wheel bolts
Never overlook the importance of secure wheel bolts in maintaining safe wheel attachment. Loose bolts can cause wobbling wheels and unsafe driving conditions. If your steering wheel shakes when braking or cornering, check your wheel bolts immediately.
4. Brake system issues
If the vibration only occurs during braking, your brake discs could be warped. When the brake disc surfaces are uneven, it causes pulsations in the steering system. This problem often appears gradually and becomes worse over time, especially if the vehicle is driven aggressively or if the brakes are old.

5. Suspension or steering component wear
While less common, worn suspension parts, such as control arm bushings, ball joints, or tie rods, could be causing the steering wheel to shake. Over time, these parts can become loose, misaligned, or damaged, reducing their ability to absorb road impacts.
6. Power steering system issues
In cars with hydraulic assistance, low power steering fluid levels can also cause the steering wheel to tremble slightly, especially when turning. Other symptoms include difficulty turning the wheel and squealing noises. Moreover, a lack of ventilation or issues with the pressure relief valve can also be the underlying problem.
If you’re experiencing any of these symptoms and drive a 4x4 or off-road vehicle, you may need to install new parts for your car. You can easily find compatible replacements online using the VIN, registration number, or OE part number, or by simply selecting the vehicle make and model, e.g. Suzuki Samurai steering parts.

When and why to change your power steering fluid
Changing the power steering fluid is an important task though car owners rarely think about it. Over time, the fluid can degrade or become contaminated, reducing the effectiveness of the system and potentially contributing to steering-related vibrations.
How it’s done:
A mechanic will typically remove the old fluid using a pump, flush the system while the engine runs and the steering is moved lock-to-lock, and then refill it with new fluid. This process ensures no contaminated oil remains in the system.
Cost estimate:
You can typically expect to pay between £80 and £130, including labour, depending on your location and vehicle type. Additional costs may apply if seals need replacing. Doing it yourself could save costs if you have the right tools and experience.
Why an early diagnosis matters
Neglecting the issue can lead to more severe and expensive problems further down the line. Suspension and steering components are also checked during your annual MOT test, such as the steering rack, so ensuring everything is in good working order beforehand can save you from failing the test.

Conclusion
A shaky steering wheel is not just annoying, it’s a signal that something in your vehicle needs attention. Whether it’s the wheels, tyres, brakes, or steering components, pinpointing the problem early can save money and ensure your safety on the road. If basic checks don’t reveal the issue, visit a professional garage. It’s better to act now than risk further damage or unsafe driving conditions.
