Steering Wheel Vibration: My Car Shakes While I’m Driving
Your car shakes while driving down the highway, the steering wheel vibration is driving you crazy, and without you even realizing it, it's causing you to feel tired. It can be quite exhausting holding onto a steering wheel that’s shaking.
Do You Need an Alignment? Probably Not!
I hear this from customers all the time; they pull into the garage and say, "I need to have an alignment on my car because my steering wheel shakes when I drive on the highway."
The truth is an alignment has nothing to do with your car shaking or your steering wheel vibrating. If you tell your mechanic you need an alignment and they don't ask why, find a new mechanic. A good mechanic will always ask why you need work done on your car so they can get enough information to decide how to fix the problem on the first visit.
Alignment, Balance: Two Different Things
Mechanics use these words to refer to different operations, though sometimes you get them both done at once.
Alignments only realign the tires so they are all pointing in the proper direction while driving down the road. If a car’s tires need alignment, it may pull one way or the other instead of straight when you let go of the steering wheel, or the tires may wear unevenly (deeper on the inside than the outside or vice versa).
Alignment is something you might do routinely every year or so. It won't stop a steering wheel vibration, but it's good preventative maintenance, especially if you often drive on potholed, cracked, or dirt roads.
If a car's tires need balancing, on the other hand, it may shake at freeway speed, or the tires may wear in a cupped or scalloped pattern. Balancing a tire means making sure the weight of the tire-and-wheel unit is balanced all around the axle, with every section having equal weight.
The first step in balancing a tire is to match the heaviest part of the rim (usually the valve stem) to the lightest part of the rim (a yellow dot painted by the manufacturer on the tire's sidewall). Then the mechanic places the tire and rim on a balance machine, which positions plastic or metal weights as needed on the outer part of the rim to fine-tune the balance.
Balancing is something you might do routinely whenever you rotate the tires, every six months or 6,000–7,500 miles. Sometimes tire stores will offer you lifetime tire balancing and rotation. I highly recommend this service. Checking the tires routinely to see if they are wearing oddly will make them last longer and cost you less in the long run.
Tires Out of Balance
The most common reason your tires shake or your steering wheel vibrates is simple: Your tires are out of balance. Tires take a beating when they hit potholes, bridge expansion joints, and curbs. Hitting any one of these objects could knock off a wheel weight, dent a rim, or cause a bubble in the sidewall of the tire, causing it to be out of balance. If you lose a wheel weight, it's an easy fix; you just need to have your tire balanced at the local garage.
Balancing should cost around $15–20 a tire. Of course, denting a rim or damaging a tire could end up costing you more, because you might have to replace the tire instead of just balancing it.

Foreign Objects, Snow, and Ice Can Make a Steering Wheel Shake
Another common cause of steering wheel vibration or car shake is having something lodged in a tire, like a large bolt, or any metal object you may have picked up from the road's surface (I have seen even wrenches and screwdrivers impaling a tire).
If you live in an area that has snow, plowing through a snowbank could cause snow and ice to become trapped in the rim or wheel and cause a serious steering wheel vibration. Luckily, this is easy to fix: Just rinse out the snow and ice with a garden hose or pressure washer.

Low Tire Pressure Can Cause Your Car to Shake
In addition to being a common cause of steering wheel vibration or car shake, low tire pressure can cause the following problems:
- poor fuel mileage
- abnormal tire wear
- tire-edge wear
- chopping or scalloping
And the list goes on. A quick check of your tire pressures can save you money in the long run, in many ways.
In cold weather, tire pressures drop. When the temperatures outside drop below 30˚F, I recommend raising the tire pressure about 3 psi above where you would normally keep it.
It's smart to keep a tire pressure gauge in your glove compartment.
Bald Tires Cause Very Bad Vibrations
If your tires are so worn that the ridges on the tread are smoothed out or steel fibers are showing through the rubber anywhere, change your tires immediately. Bald tires will definitely cause your steering wheel to vibrate and your car to shake. Furthermore, if you continue driving on bald tires, they are likely to blow out, and having a tire blow out at highway speeds is extremely dangerous, especially if it's a front tire.
Don't be afraid to look at your tires to see if bald tires are causing your problems. You need to physically look at each tire. Turning the steering wheel to one side will give you a better view of the tread surface on your front tires. You will need to get on your hands and knees to check your rear tires closely.
Other Vibrations That Could Be Confused With Tire Vibration
Vibrations in your car don't always come from tire problems. In the first video, there is not only bad shaking from an unbalanced tire, but also a wheel-bearing noise that is louder when the steering wheel is turned to one side. In the second, the car shakes hard when the brakes are applied; the problem is with the brake rotors.

Questions & Answers
My steering wheel shakes when I brake doing 70 down to about 50. It is a 2016 Ford EcoSport. I have had discs checked, the balance corrected, and the tires are fine. I'm just wondering if you know what else it could be?
The most common reason for steering wheel shake when braking at highway speeds is a warped rotor. To repair the vibration you would need to either cut the rotors or replace them.Helpful 42
The whole front end of my car shakes when I get up to 60. It gets worse the faster I drive. The shaking is very inconsistent, though. Sometimes it hits 65 before it shakes, but other times its barely 60. I just had my tires balanced, and the shaking isn't consistent. It'll shake for a second or two, then stop, then shake, then stop and so on. What could this be?
If your vehicle is a front wheel drive car, it's possible one of the inner CV joints has a problem, especially if the vibration is while accelerating. If the shaking wasn't there before the balance, I recommend bringing back to the mechanic so they can recheck their workmanship.Helpful 29

I purchased a 2012 Jetta, but I'm having trouble with the vehicle shaking and vibrating starting at 60 mph. After 80 mph it lessens slightly. I had brand new tires aligned and balanced, but that didn't work. I changed the left CV joint and wheel bearings on both sides, and nothing. I'm running out of options, can you help?
I truly believe the problem is in the tires. I recommend bringing it back to the shop that installed the tires and go for a road test with them so you can point out the issue. If they rotate the tires front-to-rear and rear-to-front, the vibrations should change if the tires are the issue. If it doesn't change, the problem is somewhere else. Balance issues are very time consuming and nine times out of ten, if the vibration wasn't there before the tire swap, it's most likely the tires.Helpful 4
I just bought a car in 2008, and it's a 2008 Volkswagen Passat. When I'm driving down the highway and have to give it gas, it feels like my car wheel wants to break off or something. Whenever I'm not on the gas it's fine, but the moment I give it gas, my vehicle starts to shake really bad. It has new tires and has been balanced and has had an alignment done. Any thoughts on my problem?
The first thing to check is the wheel lug nut torque just to be on the safe side. The most common cause of vibration on acceleration is the inner CV joints. When the CV joints have play or looseness, it can vibrate on acceleration. If the CV joints are ok, have the front suspension checked for any loose or worn ball joints or tie rod ends. If the front suspension is tight, it's possible your tires are the cause, especially if they are cheap tires. I recommend bringing it back to the place you bought it and have a mechanic go for a ride with you so you can point out the problem, if they are reputable they will most likely fix it for you. Hope this helps.Helpful 1
