A common cause of grinding noises under your car are failing wheel or hub bearings. Wheel bearings allow the wheel and tire to rotate and are designed for low friction, while hub assemblies have an additional responsibility of securing the wheel and tire to the vehicle.
If your transmission makes a grinding noise when you shift gears, you are likely experiencing friction between gears due to insufficient transmission fluid, worn transmission linkage, maladjusted binding, or a “dragging clutch.” If you hear grinding sounds when shifting from neutral to any gear, you may be dealing with …
If you notice your car making a grinding sound when it accelerates, your issue is likely to do with your transmission, a problem with your differential, a bad wheel bearing, a damaged CV joint, or a worn engine/motor mount.
Hey there, this may be caused by a worn out or failing CV joint or potentially a brake pad with a rock or some kind of debris stuck in it. As you may know, a CV joint allows the wheels to receive power as well as turn.
Most likely, if it is true grinding that you hear, the problem is related to the starter. Causes include the starter not lining up correctly with the ring gear on the flywheel, missing or damaged gear teeth, or a faulty solenoid. Replacing the starter is most often the right solution.
If your car has an automatic transmission, one of the most disconcerting noises that you can hear coming from your transmission is a grinding noise. When a grinding noise occurs with your transmission, it could mean a serious problem with your planetary gear system.
A healthy transmission will shift between gears smoothly and there won`t be any slippage. Low fluid levels can cause gears to miss, which will result in a grinding sensation.
A grinding or shuddering sensation is common when a transmission has trouble shifting fluidly. Sounds: Any grinding noises while shifting or knocking noises while in neutral are clear indications of a transmission in trouble.
The most common causes of grinding noises in automobiles are worn-out brakes, a faulty CV joint, or transmission issues. It`s important to note that, whichever component is causing the grinding noise, it needs immediate repair.
Typically this is a sign of worn out wheel bearings, but that can also happen in reverse as well. It`s possible that you have a transmission issue or a front wheel brake rotor is warped.
One possible cause is debris or dirt stuck in the brakes, which can create friction and lead to a grinding noise. Another potential reason is a misalignment of the brake calipers, causing them to rub against the rotor instead of smoothly pressing against it.
Most of the time, the groaning sound that occurs when applying reverse brakes is the result of a worn-out brake pad. The squealing sound you hear is the brake pads grinding against the rotors. However, if the brake pads have shifted, you`ll hear that familiar click as well.
IMPORTANT: If a drive is making a grinding sound during use, this could mean that physical damage is being caused to the drive`s platters by continued use. If you absolutely need any data on the drive, contact Data Recovery Services immediately before troubleshooting.
If your gears grind frequently when driving, and it`s not due to driver error, it`s not a good idea to carry on driving your car. The grinding noise you hear is most likely due to a worn or faulty clutch, which will only get worse or more damaged the longer you continue to drive.

My Car drives forward not backwards. In N and R rolles forward, but will not roll back. Have to lift front to move the car beck.
ANSWER : Hi there. Make sure the vehicle is on level ground with the engine warmed up when checking transmission fluid. Check the fluid for color, smell, and contamination as these could be telltale signs of what is occurring inside the transmission. It does sound like there is a shift solenoid that is not activating; this could be the 1-2 shift solenoid or the low/reverse solenoid depending on how many are in your particular transmission. These are simply valves that control the flow of hydraulic fluid used by the transmission control computer to determine the gear selection for the transmission. These solenoids can be manually activated in the same way you have described by selecting D1, D2, and so on. Since there was no change in the transmission operation when you selected D1, this could be a solenoid or electrical circuit fault. The solenoid could be mechanically broken/stuck or there could be an open circuit in the solenoid or the electrical circuit itself. Properly testing this system and components should be performed by a qualified technician and I strongly urge you utilize one for this inspection to avoid replacing unnecessary parts.

Car makes grinding noise – 1996 Chevrolet Corsica
ANSWER : Hey there, thanks for writing in. I would have a professional mechanic check out the constant velocity joints on your vehicle. One or more of them may be worn enough to cause the noises you describe. S/he can diagnose and replace any failed CV joints.

The driver’s seat will not move forward and backward. When I move it forward it makes a sound and then stops.
ANSWER : There is a small motor and worm gear inside the seat that moves to allow the adjustment of the angle of the back of the seat. The motor may have a malfunction or there may be an obstruction on the gear that is making the motor work much harder to move the seat until it stops to keep from overheating. Consider hiring an experienced technician like one from YourMechanic who can come out to take a closer look at the malfunctioning seat adjuster and offer a more personal diagnosis.

Switched to 4WD – did fine for a little then started making grinding noise. Now car won’t move and the 4WD light is blinking.
ANSWER : Hi there. If the 4WD light is blinking and you hear a grinding noise when the transmission is in drive or reverse only, then the transfer case has either broken the fork inside the case or the syncronizer jammed up and is grinding the gears inside the case. If the noise is not coming from the transfer case, then the front differential could be damaged. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your 4WD not working issue.

Replaced both CV axles car still won’t move can shift the gears put in park made grinding noise automatic transmission
ANSWER : Hi there. In most cases, when a CV axle breaks while the vehicle is in motion, additional damage will be done to transmission components or gear system components as well. The only way we can really help is to have a professional mechanic come to your location and complete a car will not move forward inspection, to see if they can inspect the vehicle at your location and determine what is causing this problem.

My car makes a really annoying noise and sometimes dies right after
ANSWER : Hi there. From the description you have provided your vehicle’s moaning noise and intermittent stalling problem could be any number of things. It could be a failed alternator diode making the moaning noise and affecting the idle.

A failed alternator diode(s) allows voltage to flow both directions or no flow at all resulting in noise heard and erratic electrical operation. It could be a faulty idle air control valve. The idle air control valve can make noise and would account for the erratic idle and sporadic dying. It could be an accessory component, such as an A/C compressor, serpentine belt tensioner, or idler pulley, power steering pump making noise and placing undo load on the engine at idle. If you would like to have this done, a certified professional from YourMechanic can come to your car’s location to diagnose the noise and stalling issue.

When I put my car into drive it makes a loud grinding noise and doesnt move.
ANSWER : Hi there. The transmission may have broken the differential or a CV shaft (constant velocity shaft). If a CV shaft was to break, then all of the power will go to the broken shaft. When you said that you stopped really fast, depending on how you stopped the vehicle will determine on how the transmission failed. The grinding noise is the gear train being destroyed or the CV shaft spinning. Check under the vehicle to see what has failed. If you see the CV shaft spinning, then the CV shaft was broken and needs replaced. If the CV shafts do not move and are solid, then the transmission needs rebuilt or replaced, if the shell is not broken. If you need further assistance with your vehicle having a grinding noise, then seek out a professional, such as one from Your Mechanic, to help you.
