Loud noise from car while driving slow

Very loud, intermittent noise coming from the front driver's side. It varies between a high-pitched squeal and a banging or grinding noise. While it is not consistent, it is getting worse, and seems to happen while driving at lower speeds.
Experienced mechanics share their insights in answering this question :
The fact that it is speed related leads me to think it is somehow related to the tire area. Calipers are what actually apply the brakes on the car when you step on the pedal. If one of the caliper bolts broke, the brake pad will dislodge possibly making a squeaking or grinding sound. The banging could be the caliper hitting the inside of the wheel. Because brakes are a safety concern, I suggest seeking a mechanic such as one from YourMechanic to help you properly diagnose the noise that your car is making.

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.
Usually, leaking or worn-out bearings will create a high-pitched grinding or squeaking sound. On the other hand, bearings that are seized or seizing will deliver more of a grinding sound. You may also hear a loud belt squeal.
If you hear this grinding noise both while you`re driving and idling, it`s possible that worn-out bearings are to blame. If the grinding noise comes when you shift, it`s likely due to a worn clutch. Grinding when you turn a corner could be due to a CV joint that needs to be replaced or another suspension issue.
The suspension system absorbs the shocks and vibrations from bumps, potholes and other defects on the road. It normally provides a smooth ride, but a squealing noise could indicate wear and tear in the springs or shock absorbers. It`s best to get a qualified mechanic to take a look.
If you`re hearing a grinding sound in your car, this could indicate that the alternator is going bad. The grinding sound may be caused by a worn-out bearing. Your car can also make a whining sound when the voltage regulator is sending signals to the alternator to charge more than is necessary.
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 …
When your engine oil is running low, your engine`s components stop receiving the lubrication they need to function properly. Once this happens, you may start to hear clunking, knocking, ticking, or grinding noises coming from your vehicle`s engine.
If you ever hear growling or whining noises coming from under the hood, you could have alternator problems, which should be checked out by a professional ASAP. This growling or whining sound happens when the belt that turns the alternator`s pulley becomes misaligned or rubs against the side of the pulley.
A broken bearing will compromise your ability to recharge your battery. You`ll know you have issues with your alternator if you hear grinding or squeaking from under the hood. Another sign is if your electrical components have stopped working or are not working at total capacity.
The most typical source of this screeching noise is a broken alternator belt. It`s much worse if the alternator belt squeals after being replaced. Make an appointment with a vehicle technician by searching online for a car service in Reading to completely diagnose the problem and perform the required repairs.
If you are getting a grinding noise from the front wheels when driving then the most common cause is the brakes are worn causing the brake pads backing plate rubbing on the rotor metal to metal. Have you brakes inspected to see if just the one side is worn down indicating the caliper is sticking.

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.

Oil leaking from under car and "remote control car" sound when car is first started for a few minutes until it warm up.
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

Noise when car starts and side noise brake
ANSWER : This is a common question among many Honda owners and is a valid question. This sound is usually due to the brake pads floating inside the brake calipers. I have seen numerous questions about this and had the same question myself when this design first came out. This design was intended to combat the oxidation or rust of calipers and caliper brackets which causes them to expand and create additional pressure on the pads themselves. When this happens, this can cause premature brake pad wear and breakdown of the brake pad lube (usually what is called Molykote) which then causes additional heat.

When this happens, depending on the amount of heat present, this can cause the caliper pins to freeze up causing the calipers to stick. This can cause excessive brake wear and damage. The intention of this design is purely preventative in nature and is generally not something that requires attention, however you may want to consult a professional from YourMechanic to have them come to you location to perform an inspection of your brakes to be sure this is actually the case and that they are not in need of further repair.

My car makes several loud clicking sounds that go on for about 15 seconds, is it ok to keep driving the car?
ANSWER : There are a number of things that may cause a ticking sound, however one of the most common is usually when the vehicle is low on engine oil. This can happen when the engine oil is low and the lack of proper lubrication causes the valve train components to make a ticking sound for a period of time usually upon starting the car until the engine has enough time to pump the oil to the rest of the motor. Usually, this does not cause immediate harm to the motor, unless it is dangerously low on oil. I would recommend having a professional from YourMechanic come to your location to take a look at your vehicle and change your oil.

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.

As I drive there is a loud thump noise in my rear driver side tire.
ANSWER : The description of the noise you hear is most likely a tire has a separation in the tread. The tire will still hold air but the tire will be coming apart between the treads. You should have the tire checked and if that is the case replace it as soon as possible and do not drive at high speeds with it. You may want to put the spare tire on.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

The car makes loud shaking/jarring noise when the steering wheel is only slight turned rightward. There is no noise when turning left.
ANSWER : Hi there. From the description you have provided, the noise you are hearing from the rear of the vehicle and the feeling your vehicle has while driving, should be looked at sooner than later. The swaying (fish-tail) action, could be a broken sway bar. It could also be a broken shock absorber. These are safety concerns that you’ll want to have addressed soon. I recommend having your vehicle’s noise inspected and repaired by a certified technician, like one from YourMechanic.
