Listen To Your Vehicle! (Squeals, Clunks, Grinds, and Whines Explained)

Cars make noise—but not all noises are normal. When something sounds off, it usually is.

The good news is that Big O Tires speaks your vehicle’s language! We can translate that weird “Krplnk-plnk-plnk” or “eeeeeeyyyyuuuussskkkrrrrreeeeccchhhhh”. We know what your vehicle is trying to tell you and how to fix it. And while diagnosing exact repair issues can be tricky, even for a trained professional, there are some basic rules of thumb you can use that provide clues to what might be going on ‘under the hood’.

Here’s a breakdown of common car noises, what they often mean, and when you should get them checked.

Squealing Sounds

Often heard when braking or starting the vehicle.

Common causes:

• Worn brake pads
• Loose or worn belts
• Moisture on brake components (temporary)

If the squeal happens regularly, it’s likely time for service.

Grinding Noises

Grinding is never a sound to ignore.

Common causes:

• Brake pads worn down to metal
• Transmission or differential issues
• Wheel bearing failure

Grinding usually means parts are damaging each other—repairs get expensive fast.

Clunking or Thudding

Typically heard when driving over bumps or turning.

Common causes:

• Worn suspension components
• Loose steering parts
• Failing engine or transmission mounts

These noises often affect handling and safety.

Whining or Humming

A steady whine that changes with speed can point to rotating components.

Common causes:

• Tire issues
• Wheel bearings
• Power steering problems
• Transmission wear

These sounds tend to grow louder as the problem worsens.

Clicking Sounds

Often noticeable when turning.

Common causes:

• CV joint wear
• Axle issues

Clicking during turns is a classic early warning sign—and catching it early matters.

Rattling Noises

Rattles can be tricky, but they’re worth investigating.

Common causes:

• Heat shields
• Loose exhaust components
• Interior trim or fasteners

Some rattles are minor; others aren’t. A quick inspection can tell the difference.

Rule of thumb: If a noise is new, louder, or changing—don’t ignore it. Cars are very good at warning us before something breaks.
