〰️ Car shakes at highway speed
Steering wheel or seat shakes around 50–70 mph. Jump to the card to show your mechanic ↓
Not a diagnosis. This explains common causes so you can ask better questions. A technician who inspects your car is the only one who can diagnose it.
What you're noticing
- A vibration in the steering wheel or seat that shows up at a certain speed, often highway speed, and may fade when you slow down.
- Shaking only when you press the brake is a different problem (usually rotors).
Likely causes (most to least likely)
- Tires out of balance. The most common cause. A lost wheel weight or new tires that need balancing. RepairPal says if vibration appears at certain speeds or grows with speed, tires get balanced first.
- A damaged tire or bent wheel. A pothole can bend a wheel or damage a tire. Look for a bulge or bubble on the sidewall.
- Worn suspension or steering parts. Worn tie rods, ball joints or wheel bearings can cause shaking, sometimes with clunks or humming.
- Alignment. Alignment usually causes pulling and uneven tire wear more than shaking. It is often sold for a shake it will not fix.
Safe to drive?
Usually OK to drive gently to a tire shop. Stop if it is getting worse.
- Pull over and check your tires if the shaking is sudden or severe. A bulge on a tire sidewall means do not drive on it. Use the spare or call for help.
- Stop and call for a tow if you hear clunking, the steering feels loose, or the car wanders. A loose wheel or failing joint is dangerous.
- Slow down until it is checked. Avoid the speed where it shakes.

Questions to ask
- Did you find a missing wheel weight, bent wheel or damaged tire?
- Will balancing alone fix this? If not, what did you find and can you show me?
- Did you test-drive it at the speed where it shakes?
- Is balancing covered by my tire purchase?
Upsells to question
- An alignment for a shake that only happens at certain speeds. Ask how alignment fixes vibration.
- New struts or shocks before the cheap balance check. RepairPal says balancing comes first.
- Tire rotation earlier than your manual's interval. RepairPal says early rotation should never be recommended.
