Golf IV / Jetta IV :: Vibration Accompanied With A Loud Droning Sound
Jan 18, 2015
So here is my situation, back in September I had to replace my passenger side cv axle on my 99' Mk IV Jetta and ever since then I have had a vibration whenever I exceed speeds over 70. This vibration is accompanied with a droning sound that gets louder the faster I go. But the weird part is all of this only happens when I am accelerating. If I push in the clutch or take my foot off of the accelerator it goes away immediately. Since all that started (for other reasons I might add) I have replaced the tires, both front ball joints, the driver side steering knuckle and both front struts.
Additionally and I'm not sure if this is related but it does seem coincidental. The muffler bumps on the body when I'm accelerating as well, but only after the exhaust has warmed up. I am at a loss. When the tires were installed they did a balance on the wheels and they didn't say anything about the wheels being bent or "out of round".

I had my A/C and dryer replaced because the last one basically wore itself out after 135K miles on my '01 TDI.
After I got the car back, whenever the air condition is turned out, I sometimes get a very loud intermittent vibration.
I made a video: [URL] ....
What could be the cause of this?

Couple days ago I took out the factory air box and cut the bottom out. I also cleaned my K&N filter at the same time. I cut the whole bottom edge to edge up to about 2" from the flapper on the motor side of the box. Re-installed and everything is tight. I drove the car and noticed a LOUD or what I consider loud noise from about 3,000rpm to redline. I am thinking it could be just the additional air being sucked from the air box. However its much louder then I would expect from a CAI. Does a CAI make a loud difference? I noticed a increase in performance so I know its working. Also, it could be described a a light, smooth sounding exhaust leak. But I am susceptible since this problem was not their prior to the intake mod.

So I have a 2004 gti that makes a very loud noise when i turn the wheel even slightly to the left there is also a vibration that shakes the whole right side of the car. I assumed based on the sound and vibration that it was the wheel bearing. the bearing was shot but when i replaced it nothing changed. so it has a brand new wheel bearing and the cv joint is good ive already checked it everything seems to be as it should. i cant think of anything else it could be. What the problem could be caused by?

So I replaced my rear coilovers on my gli assuming the driver side was broken because when over bumps it would make a loud banging sound as if it was bottoming out but after replacing them i have the same problem.

My new to me Golf makes a strange "whistle" sound around 2000+ RPM. In any gear only when accelerating. My car does not have a turbo so its not that, the sound is coming from the motor it self. Very strange.
I dont think it comes from the tranny or clutch.
Car has 95K miles on it, t-belt and water pump done at 68k (but in 2008!, inspected it and the belt looks fine, no cracks or fraying or anything) This whistle sound is so strange. My wife says it sound like a whistle then it changes to a slight vibration sound.

Driving my golf to take daughter to airport, all or a sudden there is this very loud metal scrapping sound. So I pull over and see this metal bat hanging from under the car and rubbing on the ground. At this point I'm not sure what it is and cant really budge it or dislodge it.
Anyway called for roadside assistance and a towtruck comes. The guy lifts the car a bit and is able to free this metal rod. Its about 1.8m (6ft) long and about 5mm thick (approx). Couple of photos below. Not sure if its part of suspension, steering or something else. Did have a mobile mechanic today doing some work on the cooling system (flange) he had to jack up the car.

So im trying to diagnose my girlfriends issue with her car. When she starts it, the car will make a very loud rattling sound, not really grinding, but like metal on metal contact. Sometimes the sound goes away, but when the car is cold it is a guarantee. The battery light is also on, which was not the case when the rattle first started. I first thought (and hoped) it was perhaps the serpentine belt tensioner as I researched that when it fails it can make a loud rattle sound.
Once replaced, the same issues occurred. So I went ahead and put the old one back on since it was not the issue. Note that the old one and new one both shared the same tension applied to the belt and the pulley was still smooth without issues.
Using a stethoscope to try to determine the location of the rattle a bit more precisely I found the noise to be coming more from the alternator. Weird because I recently replaced it within the last year. I went ahead and removed the tension from the belt and played with the alternator for a bit. The clutch felt good when i used a screw driver to hold the fan and tried to move the pulley. One direction moved with ease while the other direction refused to budge, perfectly normal as I researched. The thing that I noticed that I thought was unusual was the fact that the shaft of the alternator had some play (Video below).
The belt has plenty of tension on it so i do not believe that it is slipping on the alternator. I push the belt with the tensioner engaged and the tensioner does not budge.
I decided to measure the voltage coming off the alternator with the car running and it was at 10.95 which im pretty sure is very low for these cars.

I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.
When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.
Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.
I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.

We bought our 2010 RX last December--dead of winter--and never noticed this until this week, when the temps are approaching summer, like upper 80s.
The AC (and heater) fan makes a loud droning noise (low frequency, but quite loud) when the "auto" setting turns the fan to one of the two highest settings to cool the car down. Never noticed this until now because the fan never ran at the higher settings in the winter (parked in a heated garage). It makes no difference which vent setting is used, the loud drone from the fan is the same as long as it is running at the higher speeds.
Also, I'm NOT talking about the fans in the seats. This is the big fan behind the dash. Manually decreasing the fan speed reduces the drone, which becomes almost inaudible at lower fan speeds.

2004 Jetta 1.8t manual, sport package with about 85,000 miles on it and I've owned it since new.
About a year ago I had a shop replace the strut bearings while it was in for some other things. After I picked it up my alignment was jacked and there was a binding sound coming from the front end. The shop said the sound was just the springs settling in. It did go away after a while. Still don't understand why the alignment was off but I aligned it myself and all was good for a while.
About two weeks ago I myself replaced:
Lower control arms (stock VW) and ball joints (FEQ or Lemforder, not sure which) with R32 rear bushings and poly front (I HATE poly bushings but that's for another time)
Tie rod ends (FEQ)
Front brakes & rotors (stock VW)
I also threw in a oem Audi lower stress brace while I was under there but I don't think that has anything to do with my problem. Then I took it to a shop to have an alignment done on it. Everything is now within spec except that the caster is 6.6 degrees on the left front and 6.2 degrees on the right front. How does this happen?
So now my problem: There is a fairly loud binding sound coming from the front of the car randomly. It sounds like the coil spring is binding but maybe it is something else? it mostly does it when I reverse for a bit and then put it in first and drive forward or forward then reverse so something is shifting front to back. Steering doesn't really seem to have any noticeable effect.

I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.

My car has been making a loud droning noise that sounds like I am driving a jeep with some mud tires on it, when I turn to the left it gets smoother and when I turn to the right it gets louder.
I assume it is the wheel bearings. Unfortunately I now live in an apartment with no garage and no tools so it is a pain to check. My question is, what do I need if it is in fact the rear wheel bearings? The whole assembly is easiest I assume?

I know some of you can't get your truck loud enough and like to scare children and want everyone to look, but I like comfort and quiet. I'd prefer the stock exhaust and I may find one if I can't get mine quieted down but first I'd like to see if I can. The 4" MBRP exhaust was on the truck when I bought it. The thing was straight piped and I added the 30" muffler. Worked immensely but it's still too loud in the cab and there's droning at certain rpm.
Not a big deal on short drives but we use the truck for hauling and towing on long trips and that's when it becomes annoying. It looks like there's enough room for another muffler to easily fit (CC SB). Or I've thought about removing the MBRP muffler completely and putting on one of those crazy long Donaldson mufflers. Think a 2nd muffler would do much at all? Or get one long muffler?

My girlfriend has a 2007, v6, Honda Accord. She had difficulty turning the steering wheel, accompanied with a loud noise. She took it to a local garage and they diagnosed it as a leak in the power steering hose which she had replaced for about $400. When she used the car the following day, the problem was still there and seemed to be a little worse. She called the garage and they said for her to bring the car back which we'll be doing tomorrow. Also, coincidentally, we saw that Honda issued a recall for this. [URL] ...... As a result, we have the following questions:
-Is there any recourse for full or partial reimbursement from Honday? After all, if we took it to Honda, then Honda dealer would bill Honda Manufacturer anway.
-Should garages be familiar with recalls?
-Assuming the local garage fixes the problem, do you recommend that we still take it to the dealership?

My 2013 RX350 (all-wheel) has a super annoying droning sound when pressing gas pedal - it is not the smooth-humming but a kind of low cat-purring sound that is more pronounced when in low RPMs. The dealership can't tell the problem, Lexus Field Specialist acknowledged the sound and said I am not the first one to complain about it, but he doesn't think anything wrong with it. According to him, this is not the sound of the engine, but the exhaustion system. My overall experience with RX350 is not as good as I had expected: it is nosier than my previous highlander, it is also nosier than my wife's Odyssey.

I love the car, but had a few small gripes, including ride firmness and road noise. Well, the ride firmness has definitely calmed down a great deal over the first 3500 miles to now I find it has a perfect balance of handling vs. comfort. It's firm, but the bumps are not as jarring as those first 500 miles or so. I'm very happy with it.
The 2nd issue I hd/have, is road noise... or rather... I think... suspension noise. It's a faint droning/humming sound that I think comes mostly from the rear. You can start hearing it at 20-30mph on all but the smoothest of roads. The noise seems to be *in addition* to the very, very minimal tire noise I hear from the very nice stock Michelins. The harsher the road, the louder the noise of course.
My guess (and it's only a guess?) is that the metal bushing ('pillow ball') in the rear along with the other firmer suspension parts are the primary cause of this noise.
So I have tried a couple of things to try and counteract this noise:
1) Put D'amplifier Pro in the trunk - Got down the bare metal and put the stuff all of the place back there... Above the wheel wells also.
This did not stop the noise I hear.
2) I then put some sound deadening foam mats above both rear wheel wells.
This did not work.
The strange thing is that this noise is pretty faint, but unmistakable... however if I move my head forward (say, right in line with the steering wheel) 2 feet.... I barely hear it. But when I move back to the normal driving position, there it is.

I have a 2004 outback with just over 100k miles on it. It has been making a loud vibrating sound lately. It makes the sound when idling and even louder when I step on the gas, but at highway speeds the sound disappears. I do not actually FEEL a vibration, it just sounds as though something is vibrating/rattling. We had a mechanic check it out and they thought it was an exhaust issue. Apparently not, because the sound is still there.

Basically when I'm coming into my driveway (I turn to the right into it) I hit with the right front first and get this shuddering sound accompanied by a sloppy feeling in the steering wheel.
Sounds like the old door stop Springs. I sometimes get it as well when hitting bumps with either side at a time but not when hitting speed bumps or bumps where both wheels hit at the same time.
Went to the dealership but they couldn't reproduce it on the newly built read that's as smooth as glass.....

I have a 2004 Ford Focus that has always run like a champ; (71,000) miles. Two years ago it started having some really strange "issues." The car's dash light for the ABS would start to flash off and on, accompanied by a clicking sound whenever it flashed. The brakes are always fine. Next, though, the car starts kicking and "bucking" as though it wanted to die. Whenever I pulled off the road, turned off the car and turned it back on, everything was fine. This went on for weeks but it was sporadic in nature; and naturally it didn't do anything for my mechanic even when I left it there.
I finally took it to the Ford dealer who charged me $800 for a new alternator belt, but it came with no guarantee - they said they frankly didn't know whether it would work or not. Turns out it did, for a couple of years; but it has just now started doing it again. I can find nothing that I'm doing or not doing determines whether this happens or not. Now I've got the same scarey problem all over again, and every couple of years for a new alternator belt, I might as well give it up and sell. I'm getting so tired of hearing "I don't know what's wrong". Oh, by the way, the "check engine" light never goes on.

Recently I installed a GTA bluetooth system (about 4 months ago) and recently there is a squeaking noise coming from the passenger side. It almost sounds like an AC compressor issue (had the same problem with my F-250) but there is also an accompanying "gurgling" sound as well. AC problems with the Gen 2 after 160,000 miles?
