Why does my car shake at highway speed?

The short answer
Most highway shakes come from the wheels and tires. A wheel out of balance, snow packed inside the rim, a rim bent by a pothole, or a tire with a damaged belt can all cause it. Worn front end parts come next. A shake that appears suddenly or keeps growing means pull over and look.
When my car shakes at highway speed, where is it coming from?
Every wheel and tire has a heavy spot. We balance it by adding small weights to the rim until it spins evenly. When a weight falls off, the heavy spot comes back. Around town you may feel nothing. Near highway speed the wheel starts to hop, and you feel it through the steering wheel or the seat.
Where you feel it gives a clue. A shake in the steering wheel often points to the front wheels. A shake in the seat or the floor often points to the rear. Many balance shakes show up in one speed range and fade above it.
Worn steering and suspension parts can shake too. A loose tie rod end, a worn ball joint or a tired wheel bearing lets the wheel move in ways it should stay still. Those often come with a clunk, a hum, or a wander in the steering.
Could snow or mud in my wheels cause it?
In a Kootenay winter, often yes. Slush gets thrown inside the wheel and freezes there overnight. Mud does the same thing on a Forest Service Road. A chunk of ice on one side of a rim throws the balance off just like a lost weight.
If the shake started after a snowy drive, let the car thaw in a warm garage, or rinse the inside of the wheels at a car wash. If the shake goes away, you found it.
Spring is pothole season on Highway 3. A hard hit can bend the lip of a rim or break a belt inside the tire. A broken belt can show as a bulge on the tread or sidewall. Transport Canada says tires with bulges should be replaced. Put the spare on and bring the damaged tire in.
When does a shake mean pull over now?
- The shake started right after a tire change. Wheel nuts that have not seated can work loose.
- It came on suddenly, or it is getting worse by the kilometre.
- You can see a bulge, a cut, or tread lifting on any tire.
- A new clunk or a pull came along with the shake.
Any of those means get off the highway somewhere safe and look. A loose wheel or a failing tire can let go at speed. If you are unsure, call us before you drive on.
What does it cost to fix a highway shake?
It depends on what we find. Balancing comes with every changeover, at $60 for tires already on rims and $95 for a full swap. If the shake comes from worn steering or suspension parts, that work starts from $145. A bent rim or a damaged tire gets priced once we see it.
A shake that only happens when you brake is a different job. That usually points to the brake rotors, and our guide to grinding brakes covers what we check there.
Look up the highway shake line on our symptom estimator for the starting prices. Then book a bay and tell us the speed where the shake starts. We road test it, check the whole front end with the wheels off, and call with photos before any work begins.
Asked at the counter
Will a wheel alignment fix the shake?
Usually it will not on its own. Alignment sets the angles of the wheels, and when it is off you tend to see a pull or uneven tire wear. Balance and damage cause shakes. The same pothole can cause both, so we check the alignment whenever we find a bent rim. Alignment starts from $129.
Why does it only shake in one speed range?
A wheel out of balance hops at a rate set by how fast it spins. In one speed range that hop lines up with the natural bounce of the suspension, and the shake builds. Above that range it can fade. The imbalance is still there at every speed.
Can I keep driving on a small shake?
A small steady shake from balance is usually safe for a short while. It does wear tires and suspension parts faster. Transport Canada notes that the pounding from an unbalanced wheel can shorten suspension life and cause uneven tire wear. Book it within a couple of weeks, and sooner if it grows.
Do winter tires on their own rims need balancing?
Yes, when they are first mounted on the rims. After that they can lose a weight or pick up a bend over a season of frost heaves. If a shake shows up after you swap them on, a balance check is the first thing we do.
