Car Shaking After Hitting a Curb: What to Do
If your car starts shaking after hitting a curb, stop in a safe place and arrange an assessment. New vibration may involve the tire, wheel, steering or suspension. The symptom alone cannot identify the damaged part.
Do not continue driving or make repeated test runs to see whether the shaking clears. Tell roadside assistance or the repair shop about the impact and ask how the vehicle should be transported.
Severe vibration, changed steering or braking, a flat tire, visible damage or a fluid leak makes prompt assistance especially important. Follow your vehicle’s emergency instructions; a reassuring appearance does not rule out internal damage.

Treat new shaking as a reason to stop and get help
Treat shaking that begins after an impact as a new fault to investigate, not a normal reaction to drive through. Michelin advises professional attention at the first sign of vibration or shimmy.
The repair may be straightforward or may involve more than one component. Neither the cost nor the time to repair can be established from a general article.
What a professional may need to inspect
An inspection should identify the actual problem before an alignment, balancing service or replacement part is prescribed. Michelin distinguishes alignment from wheel balancing: they address different conditions, and one service does not prove the other is needed.
The areas below are possibilities to discuss with the repairer, not nine equally likely diagnoses or a home inspection procedure.
1. Wheel Alignment Issues
Alignment concerns the measured wheel angles. Pulling or an off-center steering wheel after the impact is useful information, but vibration alone does not prove that adjustment will fix the problem. Damaged parts need assessment before the alignment is corrected.
2. Bent Wheel or Rim Damage
An impact may damage a wheel. A technician can inspect its condition and check rotation and mounting as appropriate; an outside view may miss damage. Do not try to straighten a wheel at home.
3. Damaged Suspension Components
Steering and suspension components may need inspection after an impact. The repairer can check their condition and geometry against the vehicle’s service information. Do not infer a bent control arm from vibration alone.
4. Wheel Bearing Damage
Timken’s wheel-end symptom guide explains that noise and vibration have overlapping causes. A hum or shake is not enough to diagnose a bearing or identify which side needs replacement.
5. Tire Damage or Imbalance
The tire may have impact damage, pressure loss or a balance problem. Michelin’s inspection guidance includes tire and wheel condition checks before mounting. Internal damage can require removal by a tire professional; simply adding air or balancing does not establish that a damaged tire is safe.

6. Hub Damage
The hub, wheel mounting and bearing assembly can require inspection if the findings point there. A vibration does not prove the hub is bent, and owners should not jack up the car to investigate it from this checklist.
7. Vibration while stationary
Tell the technician if the vibration is also present while the car is safely stationary. That observation may change the investigation; do not assume the curb strike damaged an engine mount.
8. Wider impact or mounting-point damage
Describe any underbody contact and visible displacement. If the impact or inspection suggests wider damage, the repairer may need to assess mounting points or structure. A shaking symptom alone does not establish a bent subframe.
9. Tie Rod Damage
Changed steering can call for inspection of steering linkages, including tie rods where fitted. Component replacement should follow an actual finding and the manufacturer’s procedure, not a guess based on the noise or direction of pull.
What to do after stopping
Keep your observations limited to what you can see safely from outside the parked vehicle. Do not enter traffic, crawl underneath, jack it up or drive a test route to identify the failed part.
Take a Deep Breath and Assess the Situation
Once safely stopped, make the vehicle secure according to its manual. Keep people away from traffic and the vehicle’s potential path. If the location is unsafe, contact roadside assistance or emergency services as appropriate.
Conduct a Visual Inspection of the Wheels and Tires
From a safe position, note an obviously flat tire, bulges, cuts or visible wheel damage. Our guides distinguish sidewall bulges and bead damage. Do not use an external check to clear the vehicle for driving.
See tire damage after a curb strike for the information to give a tire professional. The photograph illustrates a flat tire; it does not diagnose why it lost air.
Describe changes in steering
Report pulling, an off-center wheel or reduced steering response that you already noticed. Do not drive again to reproduce those symptoms. Ask the repairer to inspect before prescribing an alignment.
Leave suspension inspection to the repairer
A workshop has suitable lifting equipment and vehicle-specific service information. An internet search identifying a control arm does not establish how to inspect it safely or whether it is serviceable.
Report noises without a diagnostic drive
Describe any grinding, rumbling or clunking already heard, including whether it occurred while braking or turning. Do not drive slowly around a lot to test for bearing noise, and do not choose a bearing replacement from sound alone.

Ask what testing is appropriate
Let the technician decide whether tire/wheel inspection, balance measurements, alignment measurements or other checks are required. A balance service cannot repair structural tire or wheel damage.
Use proper workshop assessment for the wheel end
Hub and bearing checks belong to the repairer’s diagnosis. The component photo is illustrative; it does not identify a damaged hub or describe a removal procedure.
Report vibration already noticed while parked
Tell the repairer whether the symptom was present at idle or only while moving. Do not run additional engine or driveline tests to provoke it.
Describe the impact location
Record which tire or underside area contacted the curb, the direction of travel and any warning lights or leaks. Photos taken from a safe position may help the repairer plan the inspection.
Ask for findings before approving parts
Ask which component failed the inspection, what measurements support the finding and what related checks are needed. Obtain an itemized estimate rather than replacing a tie rod, bearing or mount by elimination.
Give the repairer a clear account
Provide the impact history and symptoms, including any changes in braking, steering, tire pressure or warning messages. Michelin’s handling guidance treats new instability and severe vibration as urgent concerns.
Ask how the vehicle should reach the workshop and what must be confirmed before it returns to service. Follow the repairer’s and vehicle manufacturer’s instructions.
After repairs, keep an eye on your car’s performance. Any recurrence of unusual noises or vibrations should be addressed immediately to avoid long-term damage to your vehicle.
Common questions
Have more questions about car wobbles and curbs? We might have answered them below:
Can I still drive while it is shaking?
Do not continue using the car to investigate shaking that began after a curb strike. Arrange professional assessment and ask for an appropriate transport plan, especially if there is tire damage or changed braking or steering.
What will the repair cost?
The total depends on the actual damage, vehicle, parts and labor. Ask for an estimate separating diagnosis, tire/wheel work, alignment or other repairs, and transport. A universal alignment price is not an estimate for this incident.
How can I reduce repeated curb contact?
Follow vehicle tire-care guidance and review the route or maneuver that led to contact. Our guide to repeated curb contact can help with that separate issue. A driveway curb ramp changes a compatible rolled-curb crossing; it cannot repair vibration or guarantee prevention.
Arrange assessment before further use
Arrange inspection and a repair plan before further use. A symptom disappearing briefly does not establish that impact damage is resolved.
