> **Quick Answer:** Stop driving if you hear a new grinding, clunking, or thumping noise after hitting a pothole. A one-time clunk that goes away is usually just the suspension compressing hard. A noise that continues means something is damaged, possibly a bent wheel, blown tire, broken tie rod, or damaged CV axle. Any of those can cause you to lose control. Pull over safely and assess before driving further.
## What Kind of Noise Tells Me Something Is Actually Wrong?
A continuous or rhythmic noise is the red flag. A single loud bang when you hit the pothole is normal, but if you now hear a repeating thump at low speed, a grinding when turning, or a clunking over every bump, something took a real hit.
Here is what each noise usually points to:
- **Rhythmic thumping that speeds up with the car:** Flat or damaged tire, or a bent wheel causing the tire to bounce.
- **Clunking over bumps:** Worn or broken ball joint, strut mount, or sway bar end link. These are suspension components that locate your wheels. A broken ball joint can cause a wheel to fold under the car.
- **Grinding or humming from one corner:** Wheel bearing damage. Pothole impacts can crack the bearing race and cause it to fail progressively.
- **Clunking or clicking when turning:** CV axle or CV joint damage. This is especially common on front-wheel-drive cars.
- **Knocking from underneath at highway speed:** Bent rim causing vibration, or a loose heat shield rattling against the exhaust.
A bent rim on a steel or alloy wheel is one of the most common pothole results. A 3-inch-deep pothole hit at 40 mph can put enough force through the wheel to crack the bead seat and crack the rim. That is not always visible from outside the car.
## Is It Safe to Drive to a Shop, or Do I Need a Tow?
Do not drive it if the noise is accompanied by any of these: pulling hard to one side, vibration in the steering wheel, a visible lean in one corner, or a tire that looks low or misshapen. Those signs mean a structural component or tire is compromised, and driving risks losing steering control.
If the car drives straight, the steering feels normal, and the noise is a mild hum or rattle rather than a clunk or grind, you may be okay to drive slowly to a nearby shop, within a mile or two. Anything farther than that is a gamble. A damaged wheel bearing can seize completely without much additional warning. A cracked rim can fail and drop the tire off the bead while moving.
When in doubt, tow it. The repair cost of a wheel bearing or rim is far less than a blown-out crash caused by a failed suspension component. If you have roadside assistance through AAA or your insurer, use it now. Your insurer may even cover the tow if the damage is significant enough to be a claim.
## What Parts Are Most Likely Damaged After a Hard Pothole Hit?
The four components that take the most abuse are the tire, the wheel, the wheel bearing, and the suspension geometry.
**Tire:** Look for a sidewall bulge. A bulge means the internal cords are broken. That tire can blow out without further warning. Do not drive on it.
**Wheel/Rim:** Look for a visible crack or a bend in the inner lip of the wheel. Bent rims cause vibration and prevent the tire from sealing properly.
**Wheel bearing:** Not always visible. A mechanic will spin the wheel by hand and feel for roughness. On a front-wheel-drive car like a Honda Civic or Toyota Corolla, the front bearings are especially exposed because they handle both cornering and drive forces.
**Tie rod:** If the car now pulls sharply to one side or the steering feels vague, the outer tie rod end may be bent or broken. A broken tie rod means you cannot steer the car. This is a do-not-drive situation, call a tow. Read more about what happens when axle and steering c

**Strut or strut mount:** A clunking noise over every small bump often means the strut mount plate is cracked or the strut itself is bent.
## What Do I Do Right Now If I'm Still on the Road?
Get out of traffic first. Turn on your hazard lights, slow down gradually, and move to the right shoulder or a parking lot. Do not brake hard if the car feels unstable.
Once stopped:
1. Walk around the car and look at all four tires. Any sidewall bulge or obvious flat means you do not drive it.
2. Look at the wheel from the front and back. A visible lean or tilt in one corner is a suspension failure.
3. Put it in drive or reverse and creep forward a few feet while listening. Grinding or clunking during that short move confirms something is broken.
4. If anything looks or sounds wrong, call roadside assistance. If you are on an interstate or freeway, get fully off the travel lanes before you stop to inspect.
If you are stuck somewhere and need help figuring out who to call, [Car Died on Interstate: Who Do I Call First?](/car-died-on-interstate-who-do-i-call-first/) covers the priority order clearly.
If you have a full-size spare and only the tire appears damaged with no noise from the wheel or suspension, changing the tire is a reasonable option. If the noise is coming from the suspension or wheel bearing itself, swapping the spare does not fix the underlying problem.
A car shaking violently after a pothole hit is a separate warning. That article covers the threshold at which shaking becomes dangerous: [Car Shaking Violently at Highway Speed: Safe to Drive?](/car-shaking-violently-at-highway-speed-safe-to-drive/)

## Common Questions
**Q: Can a pothole damage my alignment without breaking anything?**
A: Yes. A hard impact can knock your camber or toe angle out of spec even when nothing is visibly broken. You will notice the car pulling to one side or the steering wheel sitting crooked when driving straight. Get an alignment check at any shop with a four-wheel alignment rack.
**Q: My tire looks fine but I hear a humming noise after hitting a pothole. What is it?**
A: Most likely a wheel bearing. The impact can crack or dent the bearing race, and the humming gets louder as speed increases. It often sounds like road noise but is localized to one corner of the car. A shop can confirm it by lifting the car and spinning the wheel by hand.
**Q: How much does it cost to fix pothole damage?**
A: A wheel bearing runs $150 to $400 parts and labor depending on the car and which corner. A new rim is $75 to $300 for steel, more for alloy. A tie rod end is $80 to $200 installed. A full alignment after any suspension impact is $80 to $150. If multiple parts are damaged, costs stack up quickly.
**Q: Will my insurance cover pothole damage?**
A: Comprehensive coverage does not cover road hazard damage. Collision coverage can apply if you swerve to avoid a pothole and hit something, but a straight pothole hit is typically not covered under standard policies. Some states allow you to file a claim against the municipality if the pothole was reported and not repaired, though that process is slow and not guaranteed.
**Q: Is it okay to drive slowly on a rim if the tire is flat and there is no spare?**
A: No. Driving on a flat destroys the tire, damages the rim, and can damage the brake rotor and caliper. Even at 5 mph, a flat tire on a rim for more than a block can turn a $200 tire replacement into a $1,000 repair. Call for a tow or roadside assistance instead.
