Passat (B5) :: 2003 - Low Frequency Driveline Noise Started At About 35 Mph
Apr 14, 2013
I have been recently working on a 2003 1.8T fwd Passat that I have owned since new. I recently changed the front rotors, pads and CV axles. At low speed everything is great. No vibrations or unusual harshness. Starting at about 35 mph a low frequency driveline noise starts from the driver side and starts to get drummed out by engine noise above 60 mph. The noise is not very noticeable from the passengers seat. Initially I suspected a tire, but I swapped tires front to back and the noise didn't change. I have tried loading and unloading the front tires in 45-50 mph s-turns and the noise doesn't change.( I was thinking wheel bearings). I put the car back up on stands and tried hand spinning the wheels. No unusual noise was present. I have not found any clearance issues where there might be something rubbing. I got the axles from Raxles and am at a loss. Could this be a wheel bearing or a bad CV joint? How can I tell?

Essentially, I get a clunky/pop/crinkle sound from beneath my feet in the driver's side footwell. This sound/feel occurs when I either get back on the gas after slowing down but before the car fully stops or if I take my foot suddenly off the accelerator without touching the brake.
VW told me after three tries that the "noise is from the driveline changing directions, making some noise because loads are changing on the driveline when going from deceleration to acceleration" and that it was normal.
I have seen some posts about the subframe bolts either being faulty or worn on this site and other VW sites...

I have an RX400h with about 100k miles.
The car's ML Stereo System recently started to go mad a bit: Let's say I am listening to an FM radio station on 103.3 frequency. From time to time I notice that sound quality goes bad and I can notice on radio screen that frequency changed from 103.3 to 103.25. After hitting memory button again 103.3 comes back, but after a while the problem appears once again.

No error codes or warning lights (Forscan verified)
No smoke out of the exhaust
No oil or coolant leaks
Have banging noise from the motor. When cold truck sounds normal, quiet. When it warms up, the banging becomes audible. You can hear it at idle. You can hear it under acceleration. Frequency increases with RPM
When at speed, and letting off the throttle, noise goes away.....comes back when back on the throttle. Any time during driving when I let off, engine quiets down to normal. To me it sounds like exhaust leak, bur not sure how to check for those?

My driveline has been vibrating for some time now. I changed out the rear u-joints with no improvement. I found the spline to be sloppy. I think I need a new driveshaft.

Have 2008 Santa fe with a driveline hum noise. Originally thought is was a wheel bearing so I replaced what I thought was the suspect ones (1 in front and 1 in the back). Noise still there! Carrier bearing on the drive shaft? Front axle shaft? I'm at a lose.

1988 F-150 4X4, 302, 5 speed manual Mazda transmission. I picked this truck up from a teenager and have been going through it fixing the odds and ends, just when I thought I was done a new one popped up.
There is an odd "clunk" in the driveline, but I cannot pinpoint where it is coming from. It happens almost exclusively in third gear, shifting up or down into this gear. It has happened in first gear one time that I can remember. When it happens, I hear the pop (clunk), then feel a slight jerk like when a chain slips on a bicycle.
I spent some time under the truck yesterday trying to locate it, but had no luck. Did find the yoke on the rear end , 8.8, a little loose. Found that the U-joints at each end of the driveshaft were worn out. The transfer case, BW 1356, was quite low on fluid. And there was nothing out of the ordinary with the transmission.
Tightened the yoke, replaced the U-joints, drained the T-case and refilled with fresh ATF and pulled the fill plug on the tranny to ensure it had ATF instead of gear oil in it. It did.
I hoped all of that had solved my mystery noise, but I wasn't that lucky so now I need to isolate it. Seems that if there was a problem in the T-case or rear diff, the noise would be present trough all gears wouldn't it? With it being primarily in one gear, could the problem be in the transmission? If so, can it be rebuilt for a reasonable price?

I have been hearing a slight "bang" from the front of my car , mostly when I either step on the gas or let off. It's very faint, but annoying.
So last Monday I make an appointment for the car to be looked at, and after the dealership telling me I need two other things (recalls/TS done before they will even look at the problem I am calling about, I ask that a tech be available to ride with me to cut down on the diagnosing time. They tell me that all this work will take over 3 hours, and because I live 11 miles from the dealership, they won't give me a ride, I can either get a ride from someone, wait, or get dropped off at a local mall.
After dropping the car off they tell me, other than the banging, I need a ECM update and muffler clamps for the rattling heat shield. I tell them the heat shield was removed because it was falling off and I was on a long distance trip and couldn't stand the banging against the car. They tell me, don't worry, we'll fix it. I ask that a tech ride with me and was told that, if it's audible, we'll find the problem. So, my first mistake was that I trusted them, and I leave.
About 5 hours later I get a call telling me the car is all set. I ask about the banging, they tell me it couldn't be replicated by the tech after a 10 mile drive. I was a little upset. So I guess the whole point to this story, if having any kind of noise from the front end, or when shifting into park or reverse, it's probably the TSB for the driveline axle washers.....

It's NOT a truck. But my '97 Town car happens to use the same 4R70W transmission and 8.8" rear axle that the F150 from the same era used to use....
I'm troubleshooting what I first thought were bad pinion bearings in the rear differential. On the highway the car makes a shaking/growling kind of noise that fades in and out from 55 MPH and higher. Also when you're on the throttle there is a howling type of noise that comes from the rear of the car, the harder you're on the throttle the worse it is.
I got under the car convinced that my pinion bearings were shot, looking for the smoking gun. But I can't find any noticeable play on the pinion shaft of the rear axle. Slid on up to the front of the driveshaft and there's noticeable play on the extension housing of the transmission:

Any chance this is causing my issue, or am I in for some expensive rear end work?

My 2014 TDI SEL has just recently begun making a weird noise..
At around 48-60 MPH, a very low frequency hum begins and it persists until the car has slowed almost to a stop. It is not related to road speed or engine RPM.
It is getting louder and more noticeable every day. I took the car to the local dealer and they could not hear it. I'm wondering if it is an electronically controlled fan or pump or part of the stability or antilock systems.

When I'm in 4 high and I coast I can hear something from the front drive line. It's a soft whirring/grinding type noise.
If I'm accelerating there is no sound . Only when the driveline forces reverse and the engine starts to slow the truck do I hear something.
With my hubs locked but in 2wd I don't hear anything.
Is this something to be concerned about or is it regular noise?
We have had a brutal winter so I've been in 4x4 75% of the time.

I have posted several times about my 03 Ex and it's driveline vibes- mainly highway speed and when slightly on the gas... Took it to a local 4 wheel drive shop that specializes in lifts. They jacked it up and I ran the X up to highway speed with the rear in the air. It was amazing how rough it is, even at 55mph. I hardly feel it in the vehicle at that speed while driving.
Anyway, they felt the vibration but where it is coming from. They said pinion angle looked fine and since I have a retubed driveshaft and rebuilt rear, they ruled that out. The owner has an 04 with a 6 or 8" lift and 37's and seems to know about Excursions.
I then took it to the local Ford dealer and had the service manager drive it. He strongly feels it is gear mesh with the ring and pinion. I am not totally convinced as the rear is quiet, gear wise. For that matter, my slip yoke has quite a bit of torsional slop, likely as much as the backlash on the ring and pinion but the driveshaft shop said that it is acceptable.

This is on an 2012 SEL, 34K on it. Since the last couple of months, I have noticed that there some wub-wub-wub sound coming the wheels, well, at least from the road surface while drivng on highway speeds.
The sound is just like something is touching the tires, but can't be sure. I may have sensed some very minute shaking as well which may seem correlating with the wub-wub frequency. But as you can see, I am not quite sure how describe it. It is not a distinct sound, not something very obvious. But it is there. I asked my SO too, and both of use can notice the sound independently, so it is perfectly reproducible. The sound appears to be coming from the front, but it is hard to pin point. I also tried opening the window at 65 mph, but the wind and road noise just drowns out all other sounds.
I have thought of getting its wheels balanced as the first step. Went to Costco but apparently they balance only the wheel with tires sold by them on them. I am thinking of taking it to the dealership but want to be prepared by some basic info myself. Hence this question. Hopefully, they wont come and tell me that the wheel drive shaft or some such needs to be changed.

Have a 2008 with 23,000 miles on it. Recently, I noticed that there is a low-frequency noise (squeal?) that lasts for several seconds when turning the air conditioner on or off.

I have a very long commute, 60 miles each way and 1 hour minimum. I installed a low end Cobra 40 channel CB radio to pass the time and to get traffic information. The antenna was purchased and trimmed to my car from a communication store which carries CB radios. My problem is, there is so much Radio Frequency noise generated when the Prius is put into drive (not even driven and without the gasoline motor starting) that it is picked up by the antenna and makes tons of static on the radio. The radio is virtually useless.

I took my truck in for a clunking noise in the driveline as I come to a stop and sometimes when shift into park. It is now the 7th and I'm told parts have been ordered and the truck will be worked on when parts come in. I asked to speak to general manager and still no call back. I called customer relations and nothing they can do.
Honestly I think the have me on the back burner since I'm warranty work opposed to marked up repairs. Am I being unreasonable on my expectations of repair time? I called around and a ring and pinion job is quoted at 3 days at the most. Other repairs have been approved as well and parts are in for those, but they have not actually repaired them either.

While chasing rattles I found my front driveline has a tiny bit of slop where the splines go into the yoke. (There is a bellows seal there just like the rear driveline so I am assuming it is a splined shaft into a yoke). Pounding on it with my fist there is a definite rattle and grabbing both halves you can feel a slight bit of play while twisting it back and forth. The rattle sounds a lot like the one I am hearing when I hit small bumps. Is this normal or should there be zero slop in that joint? By the way the u joints feel and look solid.

I need some speaker upgrade recommendations that'll fit into the door cards - specifically the subwoofers - I've replaced an OEM speaker in the driver side once already and it's doing the same thing as before it has a weird vibration/rattle noise with certain freqs. It may very well be the way it's sitting in there but I doubt it.

Went out to the garage to move the car ('03 GLS V6)...cranked over, almost started then died. When i tried to start again, the engine seems to crank over too easily...like NO COMPRESSION, and it is puffing smoke out the tailpipe. Did the timing belt just let go? The car has 68K.
