What Does It Mean If My Steering Wheel Shakes When I Drive
A shaking or vibrating steering wheel means a mechanical problem with your vehicle, usually with the tires or wheels, braking system (brake rotors, brake pads, or brake calipers), or the vehicle's suspension system.
With some troubleshooting, you may be able to narrow down the cause of steering wheel vibrations or shaking. Still, the vehicle should be taken to a professional auto shop to fix the problem, as the problem could worsen and lead to a serious accident.
1. Tires Out Of Balance
A common cause of a shaking steering wheel is unbalanced tires.
After a tire is installed on a rim, the technician will balance the tire using small weights that are hammered onto the rim wherever needed.
The weights can fall off, which will cause the steering wheel to shake.
Fixing an unbalanced tire is a relatively straightforward and inexpensive fix at a tire shop.
Steering Wheel Shakes Then Goes Away
The most common sign that a tire is unbalanced is a steering wheel that shakes intermittently.
This happens as the vehicle's tires rotate; they will alternate between being balanced and unbalanced with the other tires on the car.
2. Bad Wheel Bearings
If the steering wheel only shakes while turning, it could point to a bad wheel bearing .
A wheel bearing in the wheel hub allows the wheels to rotate while connected to the vehicle's suspension system.
A failing wheel bearing can lead to catastrophic consequences like a wheel falling off the vehicle, so you should fix it as soon as possible!
Symptoms of a Bad Wheel Bearing
Signs of a bad wheel bearing include a shaking steering wheel and groaning or grinding noises that increase as the speed of the vehicle increases, loose feeling steering, or maybe an ABS sensor failure.
Troubleshooting A Bad Wheel Bearing
Diagnosing a bad wheel bearing involves a couple of steps:
- First, take your vehicle out on a deserted road and listen for a grinding or groaning noise that increases or decreases depending on the vehicle's speed.
- Second, if it is safe, try listening for noises that increase while quickly changing lanes. When quickly changing lanes, the vehicle's weight will shift, increasing the load on the wheel bearing on the opposite side of the direction of the lane change. So, if you make a lane change to the right lane and the noise increases, it points to a problem with the bearing on the left side of the vehicle.
- Thirdly, you can raise the vehicle, firmly grasp the wheel in the 3 and 9 o'clock positions, and wiggle the tire violently in and out. There will be very little play in a wheel with a good wheel bearing.
- Finally, while the wheel is raised, you can spin the tire and listen for grinding noises coming from the wheel hub, which would signify a bad wheel bearing.
3. Problems With Braking System
Another common cause of a shaky steering wheel is problems with the vehicle's brake system , such as warped brake rotors, worn brake pads, or a malfunctioning or stuck brake caliper.
What Causes Steering Wheel To Shake When Braking?
If you notice steering wheel vibrations or shaking when you press down on the brake pedal, you have a problem in your vehicle's braking system, which could include:
- Warped brake rotors: brake pads press against the rotor to stop a vehicle by creating friction. If the brake rotor is wavy, it will lead to vibrations while braking.
- Worn or new brake pads: overly worn or brand new brake pads can chatter and shake the car.
- Malfunctioning brake calipers: a malfunctioning or stuck brake caliper due to corrosion or debris buildup could engage intermittently, which may cause the car to shake while driving.
Steering Wheel Shakes When Braking At High Speeds
Braking at higher speeds puts more load on the brakes versus braking at lower speeds. This leads to more vibrations at higher speeds due to warped brake rotors, worn brake pads, or malfunctioning brake calipers that may not be noticeable at lower speeds.
4. Worn Suspension Components
Components in vehicle suspension systems can cause shaking that you could also feel in the steering wheel. Parts like tie rod ends, ball joints, and parts in the steering rack like a worn-out bushing.
Can A Bad Alignment Cause Steering Wheel To Shake?
A bad wheel alignment could cause a steering wheel to shake, but it's more likely to cause the vehicle to drift on the highway, making it challenging to maintain a straight line.
5. Improperly Inflated Or Worn Tires
A deflated tire will cause the entire vehicle to shake, which you will feel in the steering wheel.
If your car tires are worn unevenly, you may feel a slight vibration in the steering wheel.
6. Loose Lug Nuts
Loose lug nuts will most definitely cause your steering to shake, often quite violently, and need to be fixed immediately as your tire is at risk of falling off!
Steering Wheel Shakes At High Speeds?
Steering wheel shaking is often caused by a rotating component, such as a wheel or driveshaft, that is out of balance. The faster the vehicle goes, the faster the unbalanced part rotates, which amplifies the shaking or vibration you feel in your steering wheel.
It is common only to feel the vibration or shaking from an unbalanced wheel at higher speeds, while the shaking is muted or unnoticeable at lower speeds.
Steering Wheel Shakes At 60 MPH
As mentioned above, if you only start to notice your steering wheel vibration or shaking at 60 MPH, it is most likely due to an unbalanced wheel. At lower speeds, the unbalanced wheel may not rotate fast enough to cause a vibration, but as you speed up, the wheel turns more quickly, increasing the severity of the shaking.
Steering Wheel Shakes At 70 MPH
A slightly unbalanced wheel might only be noticeable at higher speeds like 70 MPH or higher. This is because the wheel won't spin fast enough to notice the vibration or shake at lower speeds.
Steering Wheel Shakes At Low Speeds?
When a steering wheel shakes at low speeds, it could point to a more serious problem than if you only notice the shaking at higher speeds.
A steering wheel that shakes at low speeds then worsens significantly at higher speeds could mean that you have a wheel out of balance or a problem with your driveshaft, such as a bad u-joint.
If the shaking does not worsen significantly at higher speeds, you may have a stuck brake caliper or a problem with your suspension system, like a bad ball joint .
What Causes Steering Wheel Shake At Low Speed?
If a steering wheel shakes at low speed when a wheel is unbalanced, there is a problem with part of the steering system, like a bad bushing in the steering rack, a bad drive shaft, or a u-joint.
Steering Wheel Shaking When Accelerating?
During acceleration, various components in the vehicle are put under a higher load than usual. This includes the suspension, transmission, engine, and motor mounts, among other things.
If the car only shakes while accelerating and does not shake while maintaining a constant speed, it may be a faulty motor mount or a problem in the transmission as it tries to change gears to accelerate.
Engine problems could also cause shaking at higher engine RPMs when accelerating the car.
Is It Safe To Drive With A Shaking Steering Wheel?
It is usually unsafe to drive with a shaking steering wheel, and you should get the problem fixed as soon as possible before it leads to an accident. A shaking steering wheel prevents the driver from safely handling their car, can lead to driver fatigue, and could be problems like a bad wheel bearing, a flat tire, or loose lug nuts, which can worsen quite quickly and create a serious accident.
How Do You Fix A Shaky Steering Wheel?
The fix for a shaking steering wheel will depend on the problem.
If an unbalanced wheel causes a shaky steering wheel, the fix is a relatively simple and inexpensive wheel balancing at a local tire shop. On the other end of the spectrum would be a problem with the transmission, which would cost you thousands of dollars to either rebuild or replace.
Tire problems like being improperly inflated or worn unevenly can also cause steering wheel vibrations. If the tires are worn unevenly, a set of new tires, properly inflated and installed correctly by a professional mechanic, will solve the problem.
Conclusion
If your steering shakes while driving at a constant speed, you will most likely have an unbalanced wheel. If the steering wheel shaking worsens when turning, you could have a problem with a wheel bearing. If the steering wheel shakes only while accelerating, it could be a problem like a bad motor mount or a failing transmission.
In any case, it is important to get the car looked at by a professional mechanic as soon as possible.
The above problems can worsen quickly, leading to an increased chance of an accident or a more complex and costly fix later.
