Car Grinding Noise When Accelerating: Causes & Fixes
Are you experiencing a grinding noise when accelerating in your car? If so, it can be quite concerning. Fortunately, there are some steps that you can take to diagnose and potentially fix the problem yourself. In this article, we’ll discuss what could be causing the grinding noise in your car and how to go about finding a solution.
The most common cause of a grinding sound while accelerating is worn brake pads or rotors. This happens when the brakes have been used for too long without being replaced, resulting in metal-on-metal contact which causes the loud grating sound. Other possible causes include an issue with suspension components such as shocks or struts, problems with wheel bearings, or other mechanical issues with drivetrain components like driveshafts or axles.
Figuring out exactly what’s wrong with your vehicle can seem daunting if you don’t know much about cars. But not to worry — our guide will help walk you through diagnosing the source of the grinding noise in your car and potential solutions for fixing it!
Causes of Grinding Noises While Accelerating
Grinding, grating, and groaning noises can be a source of worry when accelerating in your car. From wheel bearings to cv joints, numerous causes could explain the grinding noise while you’re pressing down on the accelerator.
Wheel bearings wear out over time due to the constant rotation and friction produced by the wheels turning. As they become more worn, they commonly start making strange noises, like a grinding sound. This type of problem is generally found at low speeds or when cornering sharply with a heavy load in the vehicle.
To fix this issue, it’s necessary to replace the faulty bearing as soon as possible since driving around with a damaged one will further damage other parts of your car, such as the drive axles.
The CV joint, on the other hand, may also produce some noises during acceleration if it’s beginning to fail or has been damaged in an accident. It can cause loud clunking sounds when shifting gears and abnormal rattling while driving above 50 mph (80 km/h).
To determine whether it’s broken or just worn out, it’s best to inspect it closely and see if any pieces have come loose or cracked off entirely. If so, then replacing it should resolve any issues you’re having with grinding noises while accelerating.
Types Of Grinding Noises From A Car
Grinding noises from a car can be caused by different issues. It’s important to identify the type of grinding noise in order to determine its source and make necessary repairs. There are three common types of grinding noises that you might hear coming from your vehicle: wheel bearings, CV joints, and brake pads.
A wheel bearing usually makes a low-pitched hum or roar when accelerating, accompanied by vibrations felt through the steering wheel. This indicates damage to the bearings inside the hub assembly, which will need to be replaced as soon as possible.

A damaged CV joint also produces a roaring sound at acceleration, but it is more pronounced than with a bad wheel bearing. The best way to diagnose this issue is to remove the axle shaft and inspect the joint for wear and tear.
Lastly, worn brake pads cause an annoying squeal while braking; if ignored, they can eventually lead to metal-on-metal contact between the rotor and pad surfaces, so don’t forget to check your brakes regularly!
If you suspect any of these problems are causing grinding noises in your vehicle, have it inspected immediately by a qualified technician who can properly diagnose and repair it.
Common Symptoms Of Grinding Noises
Grinding noises from a car are often caused by worn-out or failing wheel bearings. If you’re hearing these grinding sounds while accelerating, this could indicate a more serious issue, and getting your vehicle checked as soon as possible is important. Common symptoms include:
- A loud grinding noise that increases with acceleration is usually the most noticeable sign of a worn-out or failing wheel bearing. As you speed up, the sound may become louder and higher pitched.
- Vibrations felt through the steering wheel: In addition to a grinding noise, you may also feel vibrations in your steering wheel when driving at high speeds (or even low speeds). This can sometimes point to issues such as bad tires, brakes, or shocks, but if there isn’t an obvious cause for the vibration, it can indicate a problem with your wheel bearing.
It’s important not to ignore any unusual noises coming from your car, as they can indicate an underlying mechanical issue that needs addressing quickly so that further damage does not occur. Take note of any changes in performance and contact a qualified technician immediately if you experience anything different from normal operation.
Diagnosing the Problem
If you hear a grinding noise coming from your car when accelerating, it could be due to a damaged CV joint or a faulty wheel bearing. To diagnose the problem, first check for any visible signs of damage on the exterior of the vehicle—such as fluid leakage.
If no signs are present, take your car for a drive and listen closely to where the sound is coming from. It’s also important to note if the sound changes in pitch or volume with acceleration.
Once you suspect that there may be a mechanical issue causing this noise, bring your car to an authorized mechanic so they can perform an inspection and determine what needs repair. The technician will likely look at other components such as the brakes, suspension system, and transmission before narrowing down their diagnosis. They’ll then make sure all parts are properly lubricated and functioning correctly.
At this point, the cause of the grinding noise should be apparent—whether it’s a damaged CV joint or a faulty wheel bearing. With these results identified by the technician, they can provide you with an estimate for necessary repairs so your vehicle runs smoothly again!
Checking for Loose Parts and Connections
Now that we have determined the source of the grinding noise, it’s time to check for any loose parts or connections. We’ll start by inspecting the wheel hubs and engine mounts. Make sure each part is properly secured, tight, and free of corrosion.
Also, take a look at the automatic transmission linkage; make sure all components are correctly attached and not coming apart in any way.
If everything looks good with these components, you can perform one more test to ensure nothing else is causing an issue: run your car up to about 40 to 50 mph on a flat surface and listen for any strange noises as you accelerate.
If there’s still a grinding sound present, then this could be indicative of something else needing attention. It may be worthwhile to get a second opinion from another mechanic if you’re unsure what might be causing the problem.
Inspecting Belts and Pulleys
If your car is making a grinding noise when accelerating, it may be due to damaged wheel bearings or some other belt-related issue. To inspect any potential issues with the car’s serpentine belt, power steering pump, and other components, you’ll need first to turn off the engine. Then, use a flashlight to check for signs of wear on the belt itself; if there are worn spots along its length, that could indicate a problem.
Additionally, look at all of the pulleys connected to the belt; they should be spinning freely without catching or wobbling, as this could indicate damage such as warping or rusting. If any part appears to have damage, it will need to be replaced before further troubleshooting can occur.
You should also listen carefully while inspecting these parts to determine whether any additional noises are present, which could help pinpoint where the issue lies. It is important not to attempt repairs unless you are confident that you know what needs replacing and how to do so safely. Otherwise, contact a professional mechanic who can diagnose and repair any underlying problems correctly and efficiently.
Inspecting the Wheel Bearings
Inspecting the wheel bearings is like digging through a dark mine to find hidden treasure. It’s essential that you check for any signs of damage, as bad wheel bearings can cause an array of problems.
To start off, take a look at your tire wear and make sure it’s even across each side; this could be an indication that one or more of your wheel assembly components are not working properly. You’ll also want to visually inspect the entire area around the tires and wheels, looking out for any rust spots on the metal parts; these could indicate corrosion in the system itself.
Finally, suppose all else fails and you still can’t determine what’s causing the grinding noise when accelerating. In that case, it may be time to take your car to a professional mechanic who specializes in repairs related to cars’ wheel assemblies.
Checking Brake Pads, Rotor, and Calipers
If you’re hearing a grinding or scraping noise while accelerating, your brake pads, rotors, or calipers are likely worn out. It would help if you started by inspecting the brake pads for any wear and tear. If they’ve become too thin to function properly, then they’ll need replacing.
Next, take a look at the condition of the brake rotors and calipers. Rotors can get warped over time if not replaced regularly, causing them to make a loud screeching sound when brakes are applied. The same applies to brake calipers – they may be sticking or otherwise malfunctioning, leading to an abnormal braking sound. In either case, both parts will need replacing in order to fix the issue with your car’s acceleration noises.
