Golf IV / Jetta IV :: 2003 - Thump Type Of Vibration Once Hit About 40 Mph
Oct 22, 2015
2003 Jetta 1.8t 83,000 miles
Mods - Coilovers and Spacers thats it
Issue - Once I hit about 40 mph I get a thump type of vibration. I originally thought it was bad tire balance, but tire balance usually become more noticeable around 60-65. My issue is mainly present at 40 - 55 and especially noticeable on deceleration. My thoughts are maybe a wheel bearing but most likely a axle on the way out. I heard it is common to blow axles on lowered MK4s. To explain the feeling better once you hit 40 mph there is a vibration that seems like a thumping or like that it matches with the rotation of the tire. The vibration is very noticeable between 40 - 55 then it fades but is still there, but to a lesser extent.

For probably years, I have had a bump, thump type noise when I start from a dead stop... say at a red light. I had it in my head, maybe there was that much slop in the drive train... as old truck is over 400,000 miles.
Yesterday, I rebuilt the driver's side axle, bearing,seals, new hub...the works.. I heard that noise again later... and my thoughts were, I did all that work and I'm going to find a lower/upper ball joint is bad, although I did look at them and thought they were fine during the rebuild.
Had my wife get in truck.... and swing wheel back & forth... so maybe I could see what was loose.. or making noise.
I was shocked... just something I never thought of looking at. The u-bolts holding the leaf springs were loose... the whole axle was shifting back and forth on the axle. I've never touched those bolts....

It makes a weird 'fppp' air shooting noise before the exhaust note and my 2003 gti vr6 makes the exact same noise. It sounds like it's coming from the intake manifold valve and not really the filter, but I'm not sure and yes my filter is clean, the noise also sounds a little bit more obnoxious and problematic in real life. What it is, I thought it was a vacuum leak but I don't wanna bring it in till i know exactly what it is,

My 03 Tacoma TRD is showing her years! The truck has about 215k and has some serious vibrations and noises going on. First off I have a constant shaking type of vibration between 25 and 35 mph, but it is also present in the higher speeds of 55 and above but sometimes it gets drowned out. I work at a ski resort so when Im coming down the mtn using 3rd gear or so to slow down I feel the vibration is the most apparent then. So far I have had 2 shops look at my driveshaft and both concluded there is nothing wrong with the u joints. I had a CV shaft installed because one of the boots was torn so I went ahead and had that replaced.
What the vibration is.....2nd is more of a intervalled whooomping sound almost like a bullfrog-like interval. As I increase speed the intervals get faster but it is a drawn out whooomp whooomp not a fast sound. It actually rattles the change in my ash tray to the bpms of the sound. Also I have a metallic clunking sound happening when I put the truck in gear (manual) or start and stop at slow speeds without using the clutch. I was driving around a parking deck the other day in first gear and it would make the sound whenever i hit the gas AND when I let off the gas. ONE MORE THING, whenever I am starting off under load in any gear, the truck jerks.....it hesitates and lurches but only at low rpms and again in any gear.

I have a 2006 b6 it has a thump/vibration at 22 to 24 miles an hour. This may sound crazy but when you live in the city its awful! VW has replaced the transmission, both front axles and wheel bearings all around the car they have put the headphones on the car and cannot find the thump. The breaks have also been replaced rotors and pads.

My new 2012 Prius III was braking with the normal Prius noises until yesterday. It as 1,000 miles on it and while my wife was driving it on the highway a person cut in front of her so she had to brake hard to avoid them. Ever since then when I press on then brake normally I hear a thump noise and feel a vibration under my right foot (just to the left of the brake and on the floor). It comes when I brake at speeds greater than about 12 mph. What it is and why it started? I'm planning on taking it in to the dealer to get it checked out...

2009 Camry with 100K Kilometers.
80% of the time the car drives perfectly smooth at all speeds. However, there are times when I'll hear a slight vibration type humming and a little (very little) vibration in the steering wheel. HOWEVER, when I touch the brakes it feels as though the rotor(s) have a major warp in them. It's so bad that I'm afraid to to slow the car with the breaks so I'll usually gear down to a lower speed first.
If I keep driving for another 5 or 10 minutes it will go away completely -- braking is as smooth a butter.

My Jetta is working again (I have done head gasket and suspension replacement).
It drives OK but when the engine hits 3.5k RPM... I get a vibration on the whole car, that disappears right away when the RPM increase or decrease a little from ~3500. What could it be? What should I look for? Some engine mount that is getting old?

I have a vibration that shows up when I am going 70 to 75 mph. I don't really feel it much at all in the steering wheel (not shaking side to side at all). It's more the whole car like I feel it in the seat more than anything. It's definitely a fast vibration so I'm sure it has something to do with wheel speed (wheels, bearings or axles?) I thought it was a bad wheel as my rear passenger wheel was bent and out of round making that tire become cupped real bad.
So time came for new tires and I decided to get a new set of wheels to put the new tires on. Got my wheels and tires from tire rack already mounted and balanced. Put the new wheels and tires on and the vibration is still there just the same. Wheel bearings all seem good. The front wheel bearings were replaced about 4 or 5 months ago (vibration was there before wheel bearings were replaced) along with a front suspension refresh kit from ECS with new lower control arms.
I'm curious if the CV axles could cause this type of vibration even though they are not making any noise. My car is not lowered at all and I am running stock wheel and tire sizes. I'm not above trying new axles as ECS has them for a good price. Checked with Raxles first but for the 24v VR6 they only have the performance ones.

I have an 04 Jetta that I recently had the trans replaced and ever since I picked it up there is a vibration in the front end. I took the car back and they said it was my DP hitting the cross member. They suspected mounts. I ordered and installed all 3 new mounts but the noise is still there and the trans mount looks crooked where the mount bolts to the trans bracket.

I drive a 12v VR6 and this morning the cars idle was very rough and different than normal, while at idle the engine vibrates a good amount but once I push on the gas the vibration goes away? Bad motor/ trans mounts? She also sounds a lot deeper now, is there anything I should be looking for? Doesn't sound like my chains are off or anything and just pulled the wires and cleaned out around the plugs, should I check the throttle body?

So recently I have been feeling this weird rumbling/vibration in my gas pedal when I really gun it. Whats weird is i feel it mostly in first and second. But i feel it only on full throttle and under boost. I am assuming it has something to do with suspension. But whats weird is it happened after i installed my dp. So would this just be a coincidence or something else? I do know for a fact that I need new strut mounts and bearings, but I've been reading up on them, and the symptoms aren't really similar.

42dd turboback ... Got it put on today and there is some pretty serious vibration on the driver seat. Why it's doing this? Or does it have to break in a bit

I own a 2004.5 PG GLI. The vibration starts at 55mph and gets worse from there. 75mph and you can hardly hold onto the steering wheel.
Some history, I bought the car in feb of 2013. When I got the car it drove fine. It was super low so I raised it a bit. The trans had the input shaft bearing issue so I got a reman trans, while I was there I put a new clutch and flywheel in. Since then the car has never driven right, feels like the tires are really out of balance.
Recently I took the car to the place I got the trans from and they told me the motor mounts were not aligned right, the subframe was bent, the bushings in the control arms were not in correctly, and some other small stuff. Ok, no biggie...? I fixed all this and still have this vibration that I never had before. The tech also told me the alignment was way out cause the car pulls hard left when you give it a good amount of gas. I had the car aligned the day before..
At this point I had replaced:
Ball joints
Wheel bearings
Clutch, flywheel
Trans
Left axle
Strut bushing - usrt race
Now I am onto replacing the subframe and junk. Long story short here is my current list of repairs.
Trans
Clutch,flywheel
Both axles
3 different kinds of wheel bearings-*** are currently in.
Ball joints
Inner and outer tie rods
R32 Control arm bushings
Front rotors and pads
Caliper slid pin rubbers
Subframe and bushings
Coilovers- put konis on, took fks off
Pretty much I have replaced the whole front end. All repairs are done by the book, correct tq specs and replacing hardware when needed.
You're thinking tires cause I have yet to talk about them. I have two sets of wheels and tires. My aftermarkets are 18x8.5 and then I have the factory bbs. I feel the vibration with both sets, the aftermarket are slightly worse but the greater rotating weight with wheel and tire comb I believe is why they are worse. I have had the wheels balanced twice and the car aligned twice. I had the car at a very well known shop in md that works with vw yesterday and they where clueless on the issue. Said maybe wheels and tires but that did not add up cause they balanced out fine.
Nothing I have replaced has made the vibration better or worse. Can you install the flywheel 180 out? It was lined up and went in fine.. Clutch install went beautiful, trans install was normal. Whys the car still pull hard left after being aligned?

Two control arms and a passenger side cv axle I get a bad engine vibration @3800 rpm. Feels like solid motor mounts. It goes away @4500 rpm.
The old cv axle was making noise from the inner joint and the control arm bushings were broken apart.
The engine vibration was not there with the old parts.

Driving on the highway the other day and I was doing about 80 and I noticed that the front end started to vibrate pretty loud so I slowed down to around 70 and it stopped. I got home and called up the local tire shop had all my wheels re balanced as I heard that could be the cause they were near perfect. Tires have about 3,000 miles on them. so yesterday I took it out to see if it would do it again and I noticed when it starts to vibrate at about 80 and I push in the clutch it stops immediately. Could my clutch be going out? or possibly like the throw out bearing.

When I'm idling and I rev the engine to exactly 1200 rpm i can feel an extra vibration coming from the engine. If i hold it at this rpm it will continue on. now this is not a violent vibration but more so of a buzz i can feel that travels to my steering wheel as well. what could it be ?
Another question is when i travel up my driveway and i hit the sloped curb at a angle i can hear a specific "clunk" sound coming from around the drivers foot well area what could this be? perhaps my axle going bad? I also heard it when I was reversing out of my parking space while turning.
I am new to this car and trying to make sure I'm doing everything i can to put it into good shape.

1.8T Car only has 73k on it.? When I am sitting at a stop I can hear a vibration sound coming from the engine bay. It goes away as soon as RPMs hit about 2000. My best guess is old, worn out engine mounts.

I lamented in the past a lot of vibrations when the engine was at 3500RPM (in any gear). I read on the forums and many people blamed the aftermarket "EMPI" axles that I mounted too. In fact, my OEM outer CV joints where seized inside the hub/spindle and one of the inner CV joints was clicking; the boots were all worn. This was the reason I went with aftermarket axles. Anyway, I rebuilt the OEM axles by keeping the shaft only, and getting good quality inner and outer CV joints. I finished today to swap back the OEM axles and, finally, no more vibrations!

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?

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.
