Strange Noise Troubleshooter
Cars make specific noises when parts fail. Select the sound your car is making to find out if you have a bad wheel bearing, CV joint, or power steering pump.
Direct Answer
A rhythmic clicking when turning is usually a bad CV joint. A roaring or humming noise that gets louder as you speed up is usually a bad wheel bearing.

Assumptions we made
- Noises are distinct and match common failure profiles
Important limitations
- Sound descriptions are subjective and can be misidentified

Decision context
What this calculator helps you decide
Use Strange Noise Troubleshooter when you need a quick, structured answer before you spend money, approve work, prepare a trip, compare options, or share information with a buyer, seller, shop, lender, or insurer. Enter the inputs you already know, review the result, then use the assumptions and limits below to decide what to check next.
Inputs and outputs
Start with the inputs that most affect this decision: Noise Description. The output is meant to make the next step easier to compare, not to replace a written quote, inspection, policy document, loan disclosure, or local rule.
The main outputs are Failing Component, Severity, Can I Drive It?, Next Steps. If one input is uncertain, change that value and compare the result again before treating a single estimate as final.
Best-use cases
This page is built around the search intent: identify car noise, clicking noise when turning, humming noise gets louder with speed. It is most useful when you want to narrow a decision, prepare better questions, or avoid missing a cost, risk, fitment issue, paperwork step, or ownership detail.
Keep the assumptions visible while using the result. If your vehicle, location, driving pattern, quote, loan, insurance policy, or listing situation is unusual, use this as a planning screen and verify the final decision with the relevant document, professional, or local requirement.
