Suspension Noises: What That Sound Means

If you’ve driven around Spokane lately, you know the roads can be rough—especially after winter. Between freeze-thaw cycles and heavy traffic, potholes are one of the biggest causes of suspension damage in the Inland Northwest.

If your car has started making new or unusual noises, your suspension could be trying to tell you something. At Japanese Auto Service (JAS), we help Spokane drivers diagnose and repair these issues before they turn into bigger (and more expensive) problems.

Why Spokane Potholes Are So Hard on Your Suspension

Spokane’s winters create the perfect storm for road damage:

• Water seeps into cracks 

• Freezing temperatures cause expansion 

• Roads break apart under pressure 
  

The result? Deep potholes that hit your suspension hard.

When your vehicle hits a pothole, the impact can affect:

• Shocks and struts 

• Control arms 

• Ball joints 

• Tie rods 

• Wheels and tires 
  

Even one bad hit can throw things out of alignment or cause hidden damage.

Common Suspension Noises (and What They Mean)

Not all car noises are equal. Here’s a breakdown of the most common suspension-related sounds and what they could indicate:

1. Clunking Noise

When you hear it: Going over bumps or potholes.  Possible causes:

• Worn ball joints 

• Loose or damaged control arms 

• Failing sway bar links 

This is one of the most common signs of suspension wear in Spokane

2. Knocking or Thudding

When you hear it: Driving on uneven roads Possible causes:

• Worn shocks or struts 

• Damaged suspension components after a pothole hit 

3. Squeaking or Creaking

When you hear it: Turning or going over bumps Possible causes:

• Dry or worn bushings 

• Aging suspension joints 

4. Rattling Noise

When you hear it: At low speeds or over rough roads Possible causes:

• Loose suspension parts 

• Worn sway bar components 

5. Humming or Grinding (Wheel-Related)

When you hear it: While driving at speed Possible causes:

• Wheel bearing damage (often pothole-related) 

• Tire damage or uneven wear 

6. Steering Feels Loose or Noisy

When you notice it: Turning the wheel Possible causes:

• Worn tie rods 

• Steering system wear or misalignment 

Common Suspension Damage from Potholes

Potholes don’t just cause noise—they can lead to real mechanical issues.

Here’s what we commonly see at JAS:

• Blown shocks or struts → reduced ride comfort and control 

• Bent wheels (rims) → vibration and air leaks 

• Tire sidewall damage or bulges → potential blowout risk 

• Misalignment → uneven tire wear and pulling while driving 

• Worn or damaged ball joints → unsafe steering conditions 

• Broken sway bar links → increased body roll and noise 

Signs You Shouldn’t Ignore

Even if your car is still drivable, these symptoms mean it’s time to get things checked:

• Vehicle pulls to one side 

• Uneven or rapid tire wear 

• Steering wheel vibration 

• Car feels bouncy or unstable 

• Visible tire or wheel damage 

• New noises after hitting a pothole 

When to Have JAS Inspect Your Suspension

Not every noise means immediate danger—but some situations shouldn’t wait.

It’s a good idea to schedule an inspection if:

• You recently hit a large pothole in Spokane 

• You hear persistent clunking, knocking, or rattling 

• Your steering or handling feels different 

• Your vehicle has over 75,000–100,000 miles and hasn’t had suspension work 

• You notice uneven tire wear or alignment issues 
  

Catching problems early can save you from more expensive repairs down the road

Why Suspension Health Matters

Your suspension system isn’t just about comfort—it directly impacts:

• Safety (steering control and braking stability) 

• Tire lifespan 

• Fuel efficiency 

• Overall vehicle handling 
  

Ignoring suspension issues can lead to a chain reaction of wear and damage.
