Having a noisy car with an engine whine can be annoying and embarrassing for you and those around you. Luckily if you have a noisy car, the repair is often relatively inexpensive. First, you need to determine what sort of noise your car is making.
Noises a broken car makes:
- Low rumbling a buzzing noise coming from the middle or back of your car
- Screeching or squeaking noise when driving that comes from the front of your car
- Squeaks creaks or clunks coming from near your wheels
- Grinding noise when turning the steering wheel or ringing noises while breaking
- Whining noise while driving coming from the front of the car
Why Does My Car Make a Rumbling or Buzzing Noise?
These types of noises are normally associated with an exhaust leak. Over time, your exhaust system will rust due to the temperature swings and moisture in your exhaust gases. This rust can eventually cause holes in the piping and mufflers allowing exhaust gas to escape which can cause a lot of noise. Luckily, fixing exhaust issues is usually relatively inexpensive and you can learn how to fix leaks in this article !
Why Does My Car Make a Screeching or Squeaking Noise?
Screeching noises are almost always associated with slipping engine belts. This can be due to a worn out belt, a bad belt tensioner or a worn or frozen accessory pulley. For more information about that, check out our article about squealing engine belts .
What Is Causing My Car's Squeaks, Creaks, and Clunks?
These sounds usually come from out near your wheels and indicate a worn suspension component and happen on rough roads, speed bumps or when pulling into or out of parking spaces. Where the sound is coming from exactly can be difficult to pinpoint. Try bouncing each corner of your car while your car is parked, or turning your steering wheel from lock to lock while stopped and listening for the sound. For a more in-depth procedure for diagnosing where your suspension problems are, check out our article about suspension noise .
Why Does My Car Make a Grinding or Ringing Noise?
Grinding noises usually start as ringing sounds that were left unattended to and are due to badly worn brake pads. Most high quality brake pads have small tab that will ring on the rotor when the pad gets worn down. If the pads aren't replaced soon enough the pad friction material will be completely worn away and the metal backing plate will start grinding on the rotor.

Why Is My Car Making Whining Noises When I Turn the Steering Wheel?
It is very common for car owners to experience a whining noise when accelerating. Cars can make these whining noises from 1 of 2 places. The transmission or the power steering system. They make similar noises because the working fluid and pumps in each have very similar designs. Luckily, the pumps are in very different places so it's usually easy to tell if you are experiencing an automatic transmission problem or if you need to check the power steering fluid. If the noise is from the front of the engine, then it's a power steering pump noise.
Generally, there are three different types of power steering systems commonly used in vehicles in the US today. A pitman arm style system uses a rotary valve and steering gear to transfer the motion of your steering wheel into hydraulically powered motion of a pitman arm. The pitman arm then moves the steering linkage to turn your wheels. The other system is called a rack and pinion system. This system turns the motion of your steering wheel into the lateral movement of a steering rack which is used to move your steering linkage turning your wheels. Lastly, many new vehicles are being fitted with electric power steering systems to help increase fuel mileage. In all belt driven power steering systems, the pump is the same. In electric power steering systems, some use an electric motor to pressurize the fluid while others skip the hydraulic fluid and just use an electric motor.
Usually, your power steering system will develop a leak in the steering gear or rack rather than in the pump, so if you're searching for a leak that would be the best place to start looking.
Once you've discovered a leak in your power steering system either by drips under your car, a visible leak or steady drop in power steering fluid level, it's important to stop the leak.
The best way to quickly stop a leak in your power steering system is to add BlueDevil Power Steering Stop Leak to the reservoir. BlueDevil Power Steering Stop Leak is guaranteed to permanently stop your leak and, best of all, it is quick, easy and significantly less expensive than replacing equipment. Once you've added BlueDevil Power Steering Stop Leak, top off your reservoir with BlueDevil Synthetic Power Steering Fluid .
After discovering the leaking power steering gear in my Dodge truck, I purchased a bottle of BlueDevil Power Steering Leak Stop from my local parts store and added half of it to my power steering reservoir. After a 1700 mile cross-country road trip, my power steering system is still leak free!
There may be some other places that noises are coming from in your engine, so we'll talk about a few of the most common just in case your noise is coming from somewhere else!
Can an Alternator Cause My Car to Make a Whining Noise While Driving?
Yes, it sure can! Your alternator has bearings inside that allows the pulley and stator to spin with the engine belt. If the belt is rubbing on the pulley due to misalignment or the bearings are worn out your alternator could indeed make a whining noise. Usually, these sounds would be described more as a squeak with the engine belt or a hum with bad bearings, so get your car started, then pop your hood and listen carefully to what the noise sounds like.
Why is My Car Making a High Pitched Noise?
Usually, high pitched noises like a squeak or a squeal are caused by your engine belts. The engine belts are typically made from a hard rubber and run on metal and plastic pulleys. If a pulley is misaligned or seized it will rub on the edge of the belt causing this squeaking or chirping. If you think this is your problem check out our article about squealing engine belts so you can fix the high pitched noise your car is making.
Why Does My Car Make Noise When I Accelerate?
When your car is accelerating the engine is working hard to push your car faster and faster so the noise you are hearing may be normal sounds. If a sound has just popped up, it could very well be an indication of a problem. The most common noises cars make during acceleration is either a sucking wooshing sort of sound or a loud exhaust noise. The wooshing noise usually indicates that you've got a vacuum leak somewhere in your engine. If this is the case, inspect your vacuum hoses and intake piping for leaks as vacuum leaks can make your vehicle run poorly and potentially damage your engine. If it is exhaust noise you're hearing, check out our article about locating exhaust leaks to find and fix your problem.
