Why is my Steering Wheel Shaking? – How to fix it
What could be more annoying than a shaking steering wheel when you are out and driving at high speeds or when you are braking at high speeds?
Not a lot of things actually. But don’t worry
In this article, I will teach you the most common causes of a shaking steering wheel and how you can fix it as fast as possible. I’m working as a car technician and have fixed these problems hundreds of times.

Possible Causes of a shaking steering wheel
There can be a lot of different causes for a shaking or vibrating steering wheel, but I will list the most common parts and I will teach you in what direction you should start your troubleshooting. This is a general list of possible causes. Go further down in the article to find the topic that fits you the most.
- Unbalanced /Damaged Wheels, Tires, Rims (Most common)
- Unbalanced /Damaged braking discs
- Worn out bushes / Worn front suspension
- Unbalanced / Damaged Driveshafts (If front wheel drive)
- Unbalanced / Damaged Cardan shaft (If rear wheel drive/4wd)
The steering wheel is always shaking at high speeds
If your steering wheel is shaking at high speeds and you can’t feel a more/less shaking when you are braking or accelerating, the most common problem is unbalanced tires or a damage to one of your wheels.
If you feel heavy shaking in the steering wheel when driving, the problem is most likely at one of the front wheels.
Check the tires & rims
Start by jack up your front wheels and turn them in the air while looking at the tires for any uneven signs. Tire separation can happen and the tire gets humps that will make your steering wheel to shake. Check for any uneven signs and damages at the rims also. If there is a lot of dirt on the rims, clean it up and try again. Check that your tire pressure is correct with a tire pressure meter. If you want to buy one you can check out this on Amazon: TEKTON 5941 Digital Tire Gauge, 100 PSI
Switch the front and rear wheels
You can try to switch place on the front and rear wheels to see if it is getting better. If you notice a difference, you do probably have an unbalanced tire.
Check front suspension
Check for any worn bushing or damaged/loose parts in your front suspension. Try to push your both front wheels in all directions when the front is jacked up, to check for any plays or strange sounds.
Balance the wheels
If you can’t find any damage to the tires or rims and no loose parts in the suspension, it can be the balancing of the tires that may be the problem.
If you check the inside or outside of the rim, you can see some weights fitted. These weights are to balance the wheel. Sometimes the balance weights are coming loose and fall off and make unbalance in the tires.
To balance with new balance weights, you have to use a wheel balancer. The most workshops do have one and it does not often cost that much to get it done. Count around 20-100$ depending on where you live.
4wd and rear wheel drive cars
If you have a rear wheel drive or 4wd car, the shaking can be caused by an unbalanced Cardan shaft. This can be really difficult to diagnose without a balancer, and you should always check the things listed before this before replacing the Cardan shaft. What you can do is to check the joints to see if they are damaged. If you have a damaged joint, you can often replace only the joint, but it’s hard to get it 100% balanced. So I recommend to let a workshop do it for you, or replace the whole Cardan shaft.
The steering wheel is only shaking when braking
If your steering wheel is only shaking when you are braking, there is most likely a problem with your front brake discs. If you can feel shaking when braking, but not in the steering wheel, the problem may be with your rear brake discs.
Inspect for any damages on the front brake discs
Jack up the front of your car and check your front discs for any damages or rust. It’s important to check the inside of the discs also, you can do it easy if you remove the tire to inspect it.
In many cases, the disc itself got unbalanced (Especially BMW) and makes shaking and vibrations in the steering wheel. If the discs are in good shape and got a lot of material left, you can give the discs to a workshop to let them lath them for you. But with my experience, it’s often cheaper and will give a lot better result to buy and replace them to new front discs.
Inspect the front suspension
The shaking when braking could also be caused by a play or any worn bushing in your front suspension. This is not that common problem, but it can be worth to check instead of replacing the discs the first thing you do.
The steering wheel is shaking when I’m accelerating
If your car is only shaking when you are accelerating and you have a front wheel drive, a possible cause is an unbalanced drive shaft or a cv joint. Start to check for any damages on the shafts and the cv joints. Check if you can feel any play that should not be there. If you have a rear wheel drive and can feel vibrations when accelerating, but not in the steering wheel, there is most likely a problem with the rear driveshafts or Cardan shaft.
In my experience, this could be really hard to diagnose with the right tools. (Even with them).
I can tell you with good confidence that if you can feel a heavy increase of vibrations when you accelerate hard – There is a driveline problem.
Give the driveshaft to a real professional to diagnose them properly, or replace them if you feel confident about it.
To figure out if it’s the left or right driveshaft can be really tough without balancing them.
The steering wheel is shaking when I’m turning and accelerating
If your steering wheel is shaking only when you are turning and accelerating, it is most likely a worn out CV joint. You could probably also hear some clapping noise from them.
If you hear that sound, check the CV joint gaiter for any leaks. If the grease is leaking out from the gaiters, and water pours in, the joints will get damaged really fast and you do probably have to replace the CV joint. Sometimes you can replace the gaiter and fill them with new grease, but it’s often just a temporary solution and after some miles, the sound will come back.
Test if it is the left or right CV joint
Go to a parking lot and turn the steering wheel max to the left and start accelerating. When you are doing this you will get the sound noticeable and you can probably identify if it’s the left or right CV joint.
The most common cause of shaking in the steering wheel is an unbalanced wheel or a damaged tire or rim. Always start by checking these the first thing you do, if the shaking is consistent.
Balancing your wheels at a workshop is often not that expensive and could absolutely be worth it, even if there is another fault.
Uneven Front brake discs is a common cause if the steering wheel is shaking when braking.
