Steering wheel jerking while driving can be caused by issues such as uneven tire pressure, misaligned wheels, worn suspension components, or brake system problems. These issues can lead to instability and make the vehicle difficult to control, especially at higher speeds.
Experiencing a steering wheel that jerks or pulls unexpectedly while driving can be alarming and potentially dangerous. This issue can range from a minor inconvenience to a significant safety concern, depending on the underlying cause. Understanding why this happens is crucial for maintaining your vehicle’s safety and performance.

Why does Steering Wheel Jerks When Driving?
Here are some common causes of steering wheel jerking –
1. Uneven Tire Pressure or Wear
One of the most common and easily fixable causes of steering wheel jerking is uneven tire pressure or wear. Tires that are underinflated, overinflated, or have uneven tread wear can cause the vehicle to pull to one side, leading to a jerking sensation in the steering wheel.
- Symptoms: The vehicle may pull to one side, especially when accelerating or braking. The jerking might be more pronounced at higher speeds or when making turns.
- Diagnosis: Check the tire pressure with a gauge and inspect the tires for uneven tread wear or damage.
- Solution: Adjust the tire pressure according to the manufacturer’s recommendations and rotate or replace tires if they are unevenly worn.
2. Alignment Issues
Improper wheel alignment can cause the steering wheel to jerk or pull to one side. This misalignment can occur due to hitting potholes, curbs, or general wear and tear.
- Symptoms: The vehicle may drift to one side, requiring constant correction with the steering wheel. The steering wheel might also appear off-center when driving straight.
- Diagnosis: A mechanic can perform an alignment check to determine if the wheels are properly aligned.
- Solution: Correcting the wheel alignment can resolve the jerking issue and improve overall vehicle handling.
3. Worn or Damaged Suspension Components
The suspension system, including components like control arms, tie rods, ball joints, and bushings, plays a crucial role in vehicle stability and steering control. Worn or damaged suspension parts can cause the steering wheel to jerk, especially when driving over bumps or uneven surfaces.
- Symptoms: You may feel the steering wheel jerk or wobble, especially when driving over rough roads. There might also be clunking noises or uneven tire wear.
- Diagnosis: A thorough inspection of the suspension system by a mechanic can identify worn or damaged components.
- Solution: Replacing worn suspension parts is necessary to restore proper vehicle handling and eliminate jerking.
4. Brake System Issues
Problems within the brake system, such as uneven brake pad wear, warped rotors, or sticking calipers, can cause the steering wheel to jerk when braking. This can be particularly dangerous if the vehicle pulls suddenly to one side.
- Symptoms: The steering wheel jerks or pulls when applying the brakes, and there may be a grinding or squealing noise.
- Diagnosis: Inspect the brake pads, rotors, and calipers for wear or damage. A mechanic can also check for any brake fluid leaks or caliper issues.
- Solution: Addressing brake system issues through repair or replacement of worn components can eliminate the jerking.
5. Power Steering Problems
Issues with the power steering system, such as a low fluid level, a failing power steering pump, or a malfunctioning steering rack, can cause the steering wheel to jerk or become difficult to control.
- Symptoms: The steering wheel may jerk or feel stiff, especially at low speeds. You might also hear squealing or whining noises when turning the wheel.
- Diagnosis: Check the power steering fluid level and inspect the system for leaks or damage. A mechanic can also test the power steering pump and rack for proper function.
- Solution: Replenishing the power steering fluid, fixing leaks, or replacing faulty components can resolve the issue.
6. Tire or Wheel Damage
A bent rim or damaged tire can cause steering wheel jerking, especially at higher speeds. This damage can occur from hitting a pothole, curb, or road debris.
- Symptoms: The steering wheel jerks or vibrates, particularly when driving at higher speeds or when making turns. You may also feel a thumping sensation.
- Diagnosis: Visually inspect the tires and wheels for signs of damage, such as bulges, cracks, or bends.
- Solution: Replacing damaged tires or wheels is necessary to ensure safe and smooth driving.
7. Steering Rack Issues
The steering rack is a critical component in your vehicle’s steering system. If it becomes worn or damaged, it can cause the steering wheel to jerk or feel loose.
- Symptoms: The steering wheel may feel loose or have excessive play, and you may notice jerking when turning the wheel.
- Diagnosis: A mechanic can inspect the steering rack for wear or damage and test its functionality.
- Solution: Replacing damaged steering rack will restore proper steering control and eliminate jerking.
Diagnosing Steering Wheel Jerking
Diagnosing the cause of steering wheel jerking requires a systematic approach. Here are some steps to help you or your mechanic pinpoint the issue:
- Visual Inspection: Start by visually inspecting the tires, wheels, and suspension components. Look for uneven wear, damage, or signs of leaks.
- Check Tire Pressure and Alignment: Use a tire pressure gauge to ensure all tires are inflated to the recommended levels. Check for alignment issues by observing if the vehicle drifts to one side when driving on a straight road.
- Test Drive: Pay attention to when the jerking occurs. Is it only when accelerating, braking, or at certain speeds? This can help narrow down the cause.
- Inspect the Suspension and Steering Components: Check for any play or wear in suspension and steering components. Worn parts can cause jerking and should be replaced if found.
- Check the Brake System: Inspect the brake pads, rotors, and calipers for wear or damage. Also, check the power steering fluid level and look for any leaks.
How to Prevent Steering Wheel Jerking issue
Once the cause of the steering wheel jerking is identified, it’s essential to address it promptly to ensure your vehicle’s safety and performance. Here are some preventive measures and solutions:
- Regular Tire Maintenance: Keep your tires properly inflated and inspect them regularly for wear and damage. Rotate your tires as recommended to ensure even wear.
- Routine Alignment Checks: Have your wheel alignment checked regularly, especially if you frequently drive on rough roads or hit potholes.
- Suspension and Steering Inspections: Periodically inspect your vehicle’s suspension and steering components for wear and replace them as needed.
- Brake System Maintenance: Regularly inspect and maintain your brake system. Replace brake pads and rotors before they become excessively worn.
- Address Power Steering Issues: Check the power steering fluid regularly and address any leaks or problems with the steering system promptly.
- Safe Driving Habits: Avoid hitting potholes, curbs, or debris on the road, which can damage tires, wheels, and suspension components.
Conclusion
A steering wheel that jerks when driving can be a sign of various underlying issues, from tire pressure problems and alignment issues to worn suspension components or brake system failures. Diagnosing the exact cause requires a careful inspection and sometimes professional help, but addressing these issues promptly is crucial for maintaining your vehicle’s safety and performance.
