In this guide, we’re diving deep into what that clunk could mean, the common culprits (from ball joints to CV joints), and how to fix the issue before it leads to dangerous (and expensive) outcomes.
Let’s turn that mystery clunk into a solved problem.
What Is That Clunking Noise When Turning?
When your car makes a clunking sound during turns, it’s often a symptom of suspension or steering component wear.
The sound might happen:
- Only at low speeds
- When turning left or right
- While going over bumps
- After hitting a pothole
But here’s the thing: that “clunk” is diagnostic gold. The more specific the sound and when it happens, the easier it is to pinpoint the cause.
Common Causes of a Clunking Noise When Turning
Let’s break down the most likely suspects.
1. Worn Ball Joints
What they do: Ball joints connect your suspension to your wheels and allow them to move in multiple directions.
Symptoms of failure:
- Clunking when turning or going over bumps
- Loose steering feel
- Uneven tire wear
If ball joints are failing, they can allow too much movement, leading to that unmistakable metal-on-metal clunk.
Pro tip: Jack up the front end and wiggle the tire back and forth—if there’s play, your ball joints may be toast.
2. Bad Tie Rod Ends
What they do: Tie rods connect your steering rack to your wheels. They help your tires respond to steering input.
Symptoms of failure:
- Clunking or knocking noise
- Loose or wandering steering
- Vibration while turning
Loose or worn tie rods allow your wheels to shift independently—hence, the clunk.
3. Faulty Sway Bar Links
What they do: Sway bars keep your vehicle stable during cornering by connecting both sides of the suspension.
Symptoms of failure:
- Clunking, especially over bumps
- Reduced handling
- Body roll during turns
Storytime: I once ignored this clunk for months. When I finally checked, the sway bar link had snapped clean off. The clunk? Metal bouncing around inside the wheel well.
4. Failing Control Arms or Bushings
What they do: Control arms allow the wheels to move up and down while keeping them aligned with the car’s frame.
Symptoms of failure:
- Clunking on turns or bumps
- Vibration in steering
- Uneven braking or pulling
Bushings dry out and crack over time, which allows excess play—and that’s what causes the knocking.
5. CV Joint Problems (Front-Wheel Drive or AWD)
What they do: Constant velocity (CV) joints allow the front wheels to receive power and still turn smoothly.
Symptoms of failure:
- Rhythmic clunking or clicking while turning
- Grease on the inside of your wheel
- Vibration or juddering under acceleration
If you drive a front-wheel or all-wheel drive vehicle and hear a clunk, the outer CV joint is a prime suspect.
6. Worn Struts or Shocks
What they do: These components absorb road impact and keep your tires in contact with the ground.
Symptoms of failure:
- Clunking or thumping
- Excessive bouncing
- Nose dive during braking
A failing strut mount can especially cause a single clunk when turning or hitting bumps.
7. Broken or Weak Coil Springs
What they do: Coil springs support the weight of your car and help cushion road impacts.
Symptoms of failure:
- Uneven ride height
- Clunking or banging noise
- Sagging on one side
Springs can rust, crack, or break—and when they do, turning puts pressure on the suspension, causing a loud clunk.
FAQs About Clunking Noises When Turning
Is it safe to drive with a clunking noise?
Short answer: Not really. Some causes (like sway bar links) might not be urgent. Others (like ball joints or tie rods) can be downright dangerous if they fail at high speed.
Can I diagnose the clunk myself?
Yes, to an extent. Jack up the car safely and check for:
- Loose movement in wheels (ball joints, tie rods)
- Leaking or cracked boots (CV joints)
- Broken parts (sway bar links)
But when in doubt? Always see a trusted mechanic.
How much does it cost to fix clunking noises? (2025)
Here’s a rough breakdown:
| Component | Estimated Cost (Parts + Labor) |
|---|---|
| Ball Joints | $150–$400 |
| Tie Rods | $100–$300 |
| CV Joint/Axle | $250–$600 |
| Sway Bar Links | $80–$200 |
| Control Arm | $200–$500 |
Pros & Cons: DIY vs Mechanic Fix
| Option | Pros | Cons |
|---|---|---|
| DIY | Saves money, rewarding for gearheads | Requires tools, time, and mechanical skill |
| Mechanic | Accurate diagnosis, warranty on repairs | Higher cost, wait time |
Key Takeaways: Don’t Let the Clunk Slide
- A clunking noise when turning usually points to worn suspension or steering parts.
- Ball joints, tie rods, CV joints, and sway bar links are the top offenders.
- Diagnosing early can save money—and possibly your life.
- Don’t guess. If in doubt, get a professional inspection.
