Started out a quiet hum under car now it's getting louder like a small motorcycle

Answers :

Your most likely solution will be to check the exhaust system for leaks, especially near any of the joints.

The job only takes a few minutes, and leaks can usually be isolated to a specific area without ever getting under the vehicle.

While the engine is running, leave the vehicle in Park or set the Parking Brake. Exit the vehicle and listen closely for an area about the middle of the vehicle where the noise is louder and more pronounced.

That will be the area to check if you intend to get under the vehicle to inspect the exhaust yourself, or the area you suggest to the mechanic to check.

My air conditioning is acting up. When i turn it on I eventually begin to hear a humming type noise that gets louder. When this starts I feel a loss of power from my engine. At times I hear a loud screeching noie coming from one of my belts (along with the humming) and when it gets too loud it sounds like something gives up and I lose my cold air. I have checked the levels and recharged my coolant (R134a), that has not solved the humming, loss of power, screeching and occasional loss of cold

Wheel Bearing? Hi. I have a 2005 Pontiac G6. Recently there is a noise coming from the front end of the car, I think its coming from the front tire area. The best way I can describe it is like a humming, almost like I have agressive tires on the car that "hum" on the road. As I drive faster the hum gets louder and it starts around 20km/h. What could this be? wheel bearings? The car is a lease and I'm handing it back in 2 months. Is it ok to leave this? Or could it be major repairs or dangerous t

I have a 1998 4 cylinder Toyota Camry. There was a loud noise from underneath of the car which was followed by loud noise, like a Harley motorcycle. I was also experiencing some issues with a lack of power being given to the car even w/ the gas pedal being pushed down to the floor. With the gas pedal pushed down the floor the RPMs would jump between 3-5 and the noise would get louder. I wasn't able to get passed 30-45 (60 coasting) while driving. Once stopped we open up the hood and the exhaust

I have a 1987 Dodge caravan with 216K on it. I have a humming - grinding sound coming from the front. I replaced the left front wheel bearing assemble ( it was pretty bad) but still have the same noise and it is getting louder. To see if the left wheel bearing was going, I jacked up the car and let the wheels spin. I could not hear any difference between left and right and I am starting to think it is the transmission. Does this have a trans-axle that would make a grinding noise like that? Thank

Try making tight turns to the right and then to the left. see if the grinding noise comes and goes. It could be your C/V joint and they need to be replaced. The noise will only come when your making the tight turns, you don't have to go fast. ... Dodge Caravan

1994 dodge ram van b250. when warm, starts easily. when cold, will crank but not start. eventually, fuel pump kicks in and primes lines, starts rough, sputters, dies, then finally starts rough and runs smooth after warming up. i get it to start by cycling the ignition key, hitting the gas tank. clicking noise from two modules on the firewall on drivers side, first quiet and faster and louder then slower, check engine light flashes, then the fuel pump hums on.

I have a 2004 dodge neon the problem is above 30mph there is a what sounds like a wheel bearing whine and vibration which gets louder with speed on the drivers side,when you turn the wheel to the right it quiets down,but it is not the wheel bearing,the noise appears to be comming from the transaxle?

This certainly has the sound of a bad wheel bearing. Be sure that both front wheel bearings are good, as I have many times seen professionals pick the wrong bearing. Another possibility however is that the cv shaft or drive axle is making the noise. ... 2004 Dodge Neon
