Why does my Chevy shake on the freeway?

A lot rides on your tires. Their condition impacts the way your car feels on the road, and how it responds to your directions. They are a direct link to road conditions and vehicle handling. If your tires are the reason why your Chevy shakes on the freeway, then there are a few things to consider.

Carefully inspect each of your tires for any of the following concerns: 

If you are not sure if the issue can be repaired, or if the tire needs to be replaced, consult a qualified technician.

Your tires require a specific amount of air pressure to perform properly. If your tires are under inflated, it could cause your vehicle to shake as you drive faster. There is also a higher chance of a blowout, if your tires don’t have enough air pressure. Check your owner’s manual to verify your tire pressure matches the manufacturer’s recommendations.

The wheels (or rims) also need to be inspected regularly. Rough roads, potholes and road debris can easily damage your wheels and be the reason why your car vibrates. Even bumping the curb when parking can lead to issues with your wheels that will need to be corrected.

Road hazards can cause damage to your wheel that may be hard to see. If you hit a deep pot hole or run over something in the road, your wheel can bend, crack or get out-of-round. When this happens, it may take a technician and special equipment to properly diagnose the issue. Often, the only solution is to replace the wheel.

When your Chevy shakes and you mostly feel it through the steering wheel, then the wheel bearings may be to blame. Worn or damaged wheel bearings generally make noise. It can sound like a mild humming, but also a sharp chirping, grinding or squealing noise that may change as your speed increases. Bad wheel bearings can be a serious problem, so get them checked if you suspect they are an issue.

The steering and suspension systems work hand in hand, so check them both to determine if anything needs to be addressed. Loose, worn, or damaged parts may need to be repaired or replaced.

If your vehicle is out of alignment, then you may notice vibrations at different speeds. It is good to have your alignment checked every time you rotate and/or balance your tires.

A ball joint is an important component in your vehicle’s suspension system. They help keep the wheels in alignment, while allowing it to turn. If the ball joint is going bad, you may hear a knocking or popping sound when you drive over large bumps in the road. When a ball joint breaks, it can be very dangerous. At high speeds, the damage to your car, and others on the road can be severe. If you suspect a faulty ball joint, get it serviced right away.
