I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.
View 1 RepliesI bought a 2002 accord with 105800 miles 3 weeks ago. I got the timing belt and water pump replaced within a week of that. I have noticed that the car makes a high pitch noise upon accelerating after replacing the belt. It does not happen always, but sometimes. I have noticed it on 3 days in last 2 weeks. A preliminary web search tells me that it could be a tight timing belt.
View 3 RepliesI have a '99 Chevy Lumina 3100 V6 with 54k miles. There is a loud, high-pitch buzzy whine that changes pitch with engine RPM/transmission speed. The whining noise is only evident while the car is accelerating (forward or reverse), and above 5 mph. I removed the serpentine belt and drove it briefly (500 feet) - the noise is still there without the belt. I figure it's safe to assume it's not the power steering pump, alternator, H20 pump, idler or belt tensioner. The transmission has had regular service, and shifts smoothly in all gears (fluid is clean and level is full). There is only a slight raspy "scraping" noise in park or neutral, which becomes almost undetectable when shifting to drive or reverse with the brake still applied.
View 1 RepliesRecently had my 105K maintenance done which was water pump and timing belt plus whatever other misc belts go with that. Had it done at an indepentdent shop. Since the job was done we have noticed a high pitched whine that increases in pitch with RPM or speed that we drive (literally sounds like a jet engine whine). I took it back to the independent shop and he suggested it was our transmission. I have noticed no difficulty when changing gears nor any engine warning lights. I contacted Honda and our vehicle was part of a transmission recall in 05 that was done already. Other sources have suggested that the whine could be the belt being too tight or the water pump. Shop supposedly used all honda parts. Should I take it back to him again and suggest that the belt is too tight? Take it to the dealer and see what they think?
View 11 RepliesI'm battling an odd suspension issue...over the last 5-7,000 miles, I've had a strange vibration issue surface that has varied in intensity depending on speed and road surface. I've had a damaged wheel trued, replaced all four tires and had all four wheels/tires RFV balanced. The vibration has changed but not quite gone away. Instead, it's been joined by an increased vagueness in directional stability (tendency to wander) at highway speed.
Last week, the tech balancing my tires said he felt my right hand front rear control arm bushing was worn. The more I've thought about this, the more I'm wondering if this is what might be the source of this mystery vibration issue. So, I really have two questions?
First, bad front CA rear bushing replaced under warranty? 15,000 miles does NOT seem like an acceptable service life for a suspension bushing? Do these bushings have a history of premature wear and failure, or am I just lucky?
Second, if I do have to replace one or both bushings (left and right pt. no. 5C407183A,) I'd like to ask if the solid bushing (pt. no. 1J0407181) from a Jetta or Beetle will work in a Passat control arm? If I do have to replace the bushing, it might be better to put a more solid piece of rubber in there instead of the flimsier original part.
I have a 99 tahoe 4x4. It has 220000 miles. I had a wheel hum that got loud when I went faster and the pitch changed with speed. It doesn't seem to matter if I swerve left or right. I took it to a dealer and was told I needed bearings, both wheels. I bought the wheel hub assembly and changed them out. I figured it is just better to change the whole assembly. Well, I still have the hum and it seems to be getting worse. I don't know if the u-joint would do that or if it could be a shaft thing. I can not tell what needs to be fixed but can usually fix them when I know what it is. I don't know if there is a transfer case problem either? I know the shaft spins when I turn the wheel. I assume the lock for 4x4 would be in the transfer case? It seems to be getting worse and I don't want to do any damage. I don't get paid for another week and have to drive 50 miles a day.
View 9 RepliesI have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.
My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.
I have a 2009 Gen. II with 48000 miles on it and it started having a high pitch noise when driving. Thought it was wind noise at first but does it at low speeds also. When you roll the right passenger side window down you can hear it much louder sounds like it is coming from the right front.
View 7 RepliesEvery morning for the last 3 days I've gone to go warm up my car and each time i turn on the car only from a cold start up i hear this loud high pitch noise from the motor. If i turn the car off and restart it. It goes away and the car is at perfect idle. what is this and do i have some serious problems?
Is this true? If it's only on a cold start up, and then it goes away during normal driving, you have no need to fear....that's the Secondary Air Injection Pump that turns on during cold starts, and the plastic hose just needs to be replaced.. If so where is it located so i can replace this hose.
My Civic started to make high pitch noise when turning right or left, and also when accelerating. It makes more noise when I keep the wheels turning but ceases the noise when I let the handle go and go straight. When accelerating, it ceases the noise as it reaches 30 mph or so. It has got 93000 miles on it. It started the noise about 10 months ago and I feel like it increased the noise over the time. I don't drive everyday and I try to drive my wife's Prius when I drive since it has better gas milage. But this noise is quite annoying and wonder what it is.
View 6 RepliesOur 2008 Honda CR-V w/120k one owner, always dealer maintained, vehicle has recently started exhibiting a little high pitch whine coming from the engine area which increases when you rev the gas. I checked the transmission dipstick and the level is just below the bottom hole (owners manual says it should be between the bottom and top hole). Would this make the whine? By adding some fluid should it go away? Is it okay to use a fluid other than Honda's?
View 3 RepliesI bought a 1995 k2500 sheyenne. There is a rather loud high pitch grinding/ squeaking noise emitting from what I would say the rear right of the truck. I have completely replaced the brake shoes and new pins and springs. No luck. What I can say is:
1. It hardly gets any louder as I speed up.
2. Still screams when in neutral, as long as the truck is rolling.
3. Rear differential has plenty of fresh fluid when I bought it.
4. If i hit a good size bump, it will run quiet for about 15 seconds.
I have a 2004 F-150 SCrew Lariat 4X4 with 80K miles. Over the past month or so, every once in awhile there would be a loud metallic "clacking" sound (kind of like sticking a peice of aluminum in a bike's spokes) that would start at higher speeds and would turn into a low pitched whirring gear sound as I slowed down and eventually there would be a thud followed by a sensation of running over a small bump and the noise would be gone. Kind of confusing I know, but that is the best way to describe it. My gut feeling is a wheel bearing or transmission problem....
View 9 RepliesI had the car checked for an odd noise that I've been noticing once the engine is warm. Almost like a humming or low pitch squealing. It's noticeable at idle and low speed from inside and outside the car. Very annoying considering the thing is a month old. Any way, I spent nearly 4 hours waiting and they came up with no solutions. Not a clue, a guess, nothing. The car is still driving normally and i needed it for tomorrow so I didn't keep it over as they suggested. The service manager said he hasn't seen anything like it, but also admitted he knew very little about the '10s. great.
View 10 RepliesI know that the injectors make a clicking/tapping noise but am I imagining the lower pitch sound here? It doesn't seem so loud all of the time but I'm sensitive and paranoid.
I have an intake too. [URL].....
I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?
I have an 03 2.0 jetta manual shifter. Never had issues before this morning. Got in car and sounded like it wanted to turn but wouldnt turn over. After a few attempts the turning sound stopped and I heard an electric pop. Now engine won't even try turning when I turn key it just clicks and engine makes a high pitch noise. Took starter and battery out got both tested and they are fine...
View 3 RepliesI lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.
View 1 RepliesI recently had to replace my drive belt on a 97' dodge grand caravan sport 3.3 engine. The belt shredded and this is how i knew i had to replace it. Since i replaced it i notice a whine type of noise that increases in pitch as the engine is accelerated. The other thing I've noticed is that all electrically related operations work better as it is accelerated. For example, the air blows harder, the wipers move faster, and the lights brighten. Now i honestly can't say that it didn't do this before i changed the belt. I wonder if a bearing is going out on a pulley. I have noticed the same behavior on my daughters 98 sable. Also note that i did get all of the pieces of the old belt out from the pulleys and i did spin each of them to make sure the were moving without any resistance.
View 8 RepliesI have a 2007 Sonata, 2.4L 4cyl. and it is making some weird noise as of late. I have done some research and from what I have read it seems like it may be a bad engine mount. One thing to note is that the noise really only happens when the car is cold and hasn't warmed up yet or on a cold day.
Basically the best description is that the noise is a high-pitched rattle/vibration noise. The noise seems to match the vibrations of the engine but doesn't seem to get more intense if I rev the engine. The noise does get quieter if I put it in neutral but it is still there. The noise also happens even if the car is parked and off, and I do something like shut the door or trunk. I haven't gotten a chance to get in there and look under the hood myself to try...
what could be causing this. The faster I go the higher the pitch sound. It only occurs when pressing the gas pedal. As soon as I let off the gas the noise is gone.
