Weird noise
When going over 20 mph my truck starts to make a rhythmic thud noise. When I brake, the noise stops and when I turn there is no noise. Just want to see if this problem needs fixing right away or if I am good to go
My car has 105566 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi, thanks for writing in. This may be a variety of things ranging from bad or worn wheel bearings to loose or broken suspension parts or potentially a driveline problem. Often times U-joints that have too much clearance in them can cause a thud type sound when the engine RPMs are up and will stop as the car slows down. I would recommend having an expert from YourMechanic come to your home or office to confirm a diagnosis on the issue and make or suggest the necessary repairs or replacements.
How to Identify and Fix Common car Problems ?

Common reasons for this to happen:
Low Transmission Fluid: For both manual and automatic transmissions, the primary cause for whining when in gear is low transmission fluid. If the fluid is too low, then the internal components of the transmission are not lubricated properly.
Air in the Heater Core: Your car`s heater core uses coolant to provide the heat for your cabin. If air makes it into the heater core, you`ll hear a bubbling or gurgling sound from the passenger side, behind the glovebox.
The most common reasons a Chevrolet Silverado 1500 makes noise when braking are bad brake pads, bad brake rotors, or bad brake caliper. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Sway bars can help keep a vehicle from rolling over when going around a sharp corner. If the sway bar breaks or is damaged it may produce a clunking or knocking sound, especially when going over bumps. Your vehicle may also had more difficulty handling when the sway bar is damaged.
Whirring or Whining
Whirring and whining noises from the engine vary as the car runs fast or slow. These sounds can indicate a number of different problems, including a failing water pump, a bad power steering pump, low power steering fluid, a failing alternator, or problems with the air-conditioning system.
Strange Noises
If the sound resembles humming, buzzing, or clunking, you may be experiencing transmission failure. Bad automatic transmissions may emit humming, buzzing, or whining noises while manual transmissions have harsher “clunking” sounds.
To gurgle is to make a sound like bubbling or splashing water. Not to be confusing, but when you gargle mouthwash, you probably gurgle. People gurgle when they say something (or make a noise) with an accompanying wet, gurgling sound. Your stomach might gurgle too, especially when you`re hungry.
“The smooth muscles that line the gut contract and squeeze food and gas through 30 feet of small intestine and large intestine. This process, called peristalsis, generates stomach sounds,” Dr. Alsheik says. “Even when you can`t easily hear these noises, your doctor can hear this digestive activity with a stethoscope.”
Creaking sounds indicate your suspension joints may be worn out or broken. These sounds are more likely to happen when you`re driving at a low speed. Alternatively, a creaking sound that gets louder over time typically indicates your car`s ball joints may be faulty.
Squeaking trucks are by no means a serious issue and is a common problem, it just means your bushings are a little dry. The simple solution to this is to apply a small amount of lubricant to the bushings.
Knocking occurs when fuel burns unevenly in your engine. When everything is going as it should, and the cylinders have the correct mix of air and fuel, the mixture burns in a controlled, progressive manner. After each cylinder`s air/fuel mixture burns, it should create a small “shock wave” in your engine.
It`s easy to misdiagnose the cause of engine knock, so you might have to pay a visit to your mechanic. Each of the engine knock causes on the previous page has a specific cure, and most of these fixes are simple. However, it doesn`t guarantee the knock will go away.
A squealing or chirping noise from the front of the engine can also be an indication of a failing water pump. It can sound very much like when a serpentine belt is making noise, and in many cases, that`s because it is.
Droning. A droning noise that gets louder as you accelerate may be coming from your tires—particularly if they`re old or worn. It could also be a sign that you have “feathered” tires, meaning the treads are wearing unevenly. Your tires are an important safety feature, so get them checked.
Buzzing and hissing
If the gear shifter or the shift linkage are making a hissing of buzzing noise while the car is moving, particularly while the vehicle is accelerating or decelerating, a loose bolt or worn rubber isolators in the shift linkage is the most common cause.
While the transmission is the most likely cause, whining while accelerating can also be caused by low power steering fluid or more serious damage like faulty alternator bearings, a malfunctioning water pump, a broken piston or a bad AC compressor.
Home radiators tend to make gurgling noises on account of trapped air within them, which is trying desperately to escape the component. Though hot water is used to heat radiator pipes, air can occasionally become trapped with this water, leading to cold spots at the bottom of the radiator.
This usually means that there is air trapped in the coolant that circulates through the core. This can happen for a number of reasons, including a blown head gasket or a leak developing in the heater control valve.
A squeaky suspension system is not just embarrassing with those squeaking noises and grinding noises, but it is also dangerous and can be extremely difficult to diagnose and fix. Your vehicle`s weight is supported using coil springs, leaf springs or torsion bars.
There is a rattling sound. A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.
Detonation knock is a knocking noise that you`ll hear when the air fuel mixture in the cylinders is detonating in more than once place at a time. Parts of the air/fuel mixture can start to ignite too early. When these mini fireballs collide, they create a knocking noise.
Adding more oil will make the noise go away, but it won`t solve the underlying cause of the noisy engine – the oil leak.
Spark Plugs That Are Worn or Misfiring
If your spark plugs are overdue for replacement, your engine knock could be attributed to that and you may also lose engine power.

Clicking noise in idle (link of Video of noise included)
ANSWER : Hi there. Although it is hard to pinpoint the exact source of this noise via a video, it sounds a lot like an exhaust leak. When the exhaust manifold of exhaust tubes age, they are exposed to elements, creating weakness in the metal and eventually will crack or break. It is also possible that this sound is caused by cylinder head hardware that is loose (such as lifters or rocker arms) or not getting enough lubrication. Again, without being there it is impossible to know for certain, but you might want to have a professional mechanic complete a car is making a noise inspection to determine what is causing this issue.

when i turn it make little noise. when press on brake and put on reverse it’s makes weird noise and shakes. thank you
ANSWER : It sounds like you may be dealing with a few issues. I would start by asking if there is a check engine light on? If there is, then getting the engine control module scanned for faults would be the first step to diagnosing the low power issue. As far as the noise over bumps and when turning, there could be a damaged CV joint or axle shaft, or there could be a loose suspension or steering component. Weak motor mounts could cause a weird noise and shake when going into reverse with your foot on the brake, so it’s possible those have failed as well. I would suggest having a qualified mechanic, such as one from YourMechanic, diagnose the noise over bumps and the noise when put in reverse.

I have a 1995 dodge ram 1500 with a 5.9 L Magnum and it is making this weird noise that started after a heater core exchange
ANSWER : Hi and thanks for contacting YourMechanic. First find all of the vacuum lines that are cracked and replace all of them. Then check the heater control valve to see if it has a vacuum leak on it. With the heater off, the valve should be off and shutting the flow to the heater core off and redirecting the coolant back to the engine. Check the coolant hoses to see if they are all the same temperature with the engine at operating temperature. It is possible that the valve has stopped working and is allowing coolant to pass through the heater core making the coolant temperature lower since the heater core acts as a second radiator. The misfire on the engine could simply be a vacuum line split and causing all of the problems. If all of the vacuum lines are replaced and the engine still misfires, then check the distributor cap, rotor, plug wires, and spark plugs for any wear and burn spots. If there is, then I suggest performing a tune up to fix the misfire. If you need further assistance with your vehicle, then seek out a professional, such as one from YourMechanic, to help you with your coolant temperature and engine misfire issues.

When I turn my car slightly to the left, I hear a humming noise almost like a rubbing noise. The steering wheel doesnt vibrate
ANSWER : The noise could be from the wheel bearing rubbing as it may have dry grease inside the bearing. The noise also could be the power steering pump as there is a load applied to the pump more than steering the other direction. Also, check the tires on the vehicle and see if the tread is rubbing on the fender or the frame as if the tires may be too wide for the steering of the vehicle.
If you need further assistance with the vehicle making a rubbing noise when turning to the left, then seek out a professional, such as one from Your Mechanic, to help you.

Timing issues? Weird noise when accelerating.
ANSWER : Hi there. Although it’s true that faulty or incorrect ignition timing will impact how smooth an engine runs, other issues like mass air flow sensors, O2 sensors and crankshaft position sensors can also cause similar symptoms. The best way to know for certain is to have a professional mechanic complete an engine is running rough inspection. By allowing them to inspect your Hyundai, they can determine if the timing is the issue, make the appropriate adjustments, or recommend the best replacement procedures.

weird noise with cold air intake and idle
ANSWER : This is a common symptom of the mass air flow sensor needing to be upgraded due to the increased air intake. The mass air flow sensor operates based upon predetermined stock tuning in the ECM. When the air flow changes, this can cause the jumping in RPM’s due to the imbalanced air/fuel mixture being created by increasing the air flow. I would recommend having an expert from YourMechanic come to your home to diagnose and replace your mass air flow sensor.
