An analogy is a term that mimics the sound or movement of the object it represents.We’re sorry you’re here because your car won’t stop grinding, but there’s nothing we can do. When accelerating, why does an automobile create a grinding noise?
Cars grind when they accelerate for one of the following reasons:
There are problems with the transmission.
Problems of the Differential
An issue with one of the wheel bearings
CV Joint Damaged
Motor Mounts That Are Damaged
Each of them is distinct, and each has a specific remedy for it.For each of the above difficulties and how to fix them, we’ve put together a comprehensive tutorial in this article.Get to the root reasons and possible solutions first!

Does Your Car Grind When Accelerating? 5 Possible Causes And How To Fix Them
Cause #1 – Transmission Issues
A transmission can generate a variety of sounds, all of which indicate that it’s about to fail. Even if you don’t hear a grinding sound, it’s probably too late if you do hear something from it. The planetary gear system of an automatic gearbox may be worn out if it makes a grinding noise when accelerating. In order to comprehend how even a small amount of damage might affect the system, you must first grasp how the system operates. The video below can help if you don’t understand. The problem originates from the fact that the engine’s speed is not in sync with the vehicle’s wheel speed. A grinding sound may be heard while you’re accelerating, or it may only be heard in a single gear. If you don’t mind a hefty repair fee (which we doubt), don’t disregard this problem.
How To Fix
Working on an automatic gearbox on your own is not suggested because it is one of the most complicated parts of an automobile. If you hear a grinding noise as you accelerate, and it turns out to be the transmission, you’ll need to take it to a mechanic. Your best bet is to get a new one installed. To learn more about transmission repairs and their associated costs, see our prior post.
Cause #2 – Differential Problems
Drivetrain components such as the differential allow the wheels to move at different rates. With out it, your car’s performance would be erratic and risky.
As a differential takes the power from the engine and distributes it among the wheels, the vehicle can be driven at multiple speeds at the same time. A whining sound may be heard if something isn’t working properly. However, if the situation worsens, it may begin grinding (especially when accelerating or turning). When this happens, it indicates that the internal gears of the differential have worn out and are no longer functioning properly.
How To Fix
The differential will almost certainly need to be replaced if it has already reached the grinding stage. There could be a lack of diff fluid, which lubricates the gears so they don’t scrape against each other, causing a whining noise. See our earlier article on differential repairs here for more details.
Cause #3 – Bad Wheel Bearing
The wheel assembly includes a wheel bearing, which serves as the mechanical link between the wheel and the axle. In a nutshell, it’s a metal ring containing a set of steel balls. Wheels can spin freely without causing excessive friction thanks to these bearings. Your tires may wear unevenly if one of your wheel bearings has been worn or broken. Another sign might be… The sound of a grinding machine (especially while accelerating or turning). When a poor wheel bearing is ignored, it can cause the wheel to lock up, putting you, your passengers, and everyone else on the road at risk. Leaving the problem unattended can also lead to further transmission and CV joint problems, as well as a deterioration of the wheel hubs.
How To Fix
If a wheel bearing is found to be defective, the best course of action is to replace it. As it turns out, this isn’t a difficult task at all, so you may do it yourself if you choose. For a step-by-by-step explanation, see the video below. Otherwise, the cost of hiring a repair business should be around $300. (this can vary depending on the make and model of your car).
Cause #4 – Damaged CV Joint
Transmission and wheel are connected by constant-velocity joints (also known as CV joints). They’re most commonly found on cars with front-wheel drive. A clicking, grinding, or popping sound is a sign that something is wrong with your car’s performance when it’s accelerating at low speeds and making a tight bend. To shift out of Park, you’ll need a good CV joint, and if you don’t have one, that’s not good. Additionally, you may notice vibrations while driving, as well as a greasy residue on the tires’ inner edges. The risk of losing control is too great to risk driving a car with a damaged CV joint.
How To Fix
Replacement is the only option for a worn CV joint. The part itself costs between $150 and $500, while the labor charges are between $500 and $800. You can easily replace it yourself if you’re prepared to put in the time and effort.
Cause 5 – Worn Motor Mounts
Engine mounts support the roughly 300-pound weight of a typical sedan’s engine. To avoid rusting, they’re built of metal, which makes them susceptible to breaking or separating. Your automobile may create a grinding noise as the engine shifts when you start it up. If your vehicle is equipped with a serpentine belt, it may cause the swirl pot hose to rub against the underside of the belt. When the weight of an engine is not properly secured, it can quickly lead to expensive repairs because the weight of it rests on other components.
How To Fix
Fortunately, repairing an engine mount is a relatively inexpensive procedure. An hour’s worth of effort should be enough to spot-weld the issue region at an auto shop. However, a shop will charge you up to $800 to replace it, so plan accordingly. It’s not difficult to do it yourself, and the cost of parts ranges from $100 to $300. For a step-by-by-step explanation, see the video below.
