7 Series :: Vibration And Clunking Only On Heavy Acceleration / Or From A Stop
Apr 17, 2010
So this vibration/ cluncking seems to be from between the front seats and mostly during off the line acceration, and from all I can find it's the flex disc, but my flex disc shows no signs of damage. Can these discs go bad without looking bad or is this possibly the hanger bearing on the driveshaft?
I am also looking for any other possibilities for the cause of this vibation/ clunking as there sounds like something is hitting the bottom of the car but there are no impact marks to show me where the issue is

Just bought my R a few months ago and love it so far. I've recently encountered a slight buzz or vibration. I'll get down to the nitty gritty and not bore you with long drawn out information. Basically under heavy acceleration the driver side vibrates/ buzzes down by the floorboard. Now this only happen under heavy acceleration. I even did a test in 1st gear. Heavy accellerate under 2k RPM's, 3k RPM's, 4k RPM's and the vibration happened under these heavy acceleration periods. It's almost like there was also a loss of power during this vibration/ buzz, which leads me to believe it might be the clutch.
I took off the prop shaft and drove in FWD for a few weeks. The vibration was still prominent. Took of both front driveshafts and inspected those and they seem perfect but THE VIBRATION IS STILL HERE. Could this be the clutch?

If you have an intake and are under heavier acceleration, do you get any vibrations in the car while getting that growl sound?
I have the intake pipe zip tied so that it is away from the brake lines but I'm trying to figure out if the vibes are coming from just the sound frequency or something or if it's something else.

Just this past weekend my wife got her 2010 Golf Highline with the 6-speed tiptronic transmission. Just a quick question about the gas pedal. when it is on "D" it really feels heavy and sluggish when going from full stop to acceleration. the pedal feels so hard and when you step on it feels like its not going at all. but as soon as it goes on 3rd everything seems ok. and then we tried putting it into "S" (sports) mode and everything was really good and quick. but when on this mode you need to be really hard on the gas pedal for it to run smooth. so i guess my question is...is it really like that when driving in the "D" mode??

Clunking noise heard during stop, start and sudden acceleration, sometimes very loud sometimes very soft or almost non existent. Hard to locate as well. Feels like I'm about to loose my axle!
My BMW is a 1995, 530I with 154000 miles on it.

I drive a 1992 325is,(auto) with 150K... a few weeks ago only when racing or hard acceleration there was banging or clunking, coming from under the E-brake area, almost sounded and felt like the back tires hopping up and down as if i where chirping gears in a riced honda. The tranny IS NOT slipping or banging etc.
Now over time it has progressively gotten worse, it started doing it when rpms jump, now i cant even accelerate, I have to feather the gas OH SO lightly or else, it clangs and bangs almost sounding like the drivetrain is slapping against the chassis. i have to accelerate extremely slowly, and lightly or else it clanks and bangs, it takes me 5 mins to get to 40mph. Can it be the guibo? or mount that keeps the drivashaft in place?

first off my truck is 2001 ford ranger 4x4 with an auto. transmission. when I'm driving around in 2wd, everything is fine...
when my 4wd high is on, and I'm starting from a deadstop my truck makes a weird "clunking" noise in the front end. If I'm stuck in mud or snow, and I give gas it keeps "clunking". where the problem comes from?

01' Screw 5.4 4wd. Went camping this past weekend and it was the first outing for this truck our TT weighs 6k. When accelerating from a dead stop going straight I'm getting a rumble strip like vibration that last a second. If I take off very easy it doesn't do it. I've seen similar post but no definitive solutions. This truck has less then a 100k on it and so far I've changed the trans filter/fluid rear end oil with modifier and new spark plugs.
Once I'm rolling and hammer down it won't do it. It's more of a annoyance then anything.

Wonder if its dry driveshaft slip splines? Only happens when leaving a dead stop under hard acceleration. Hard to describe sound, but seems to be coming from behind me, almost sounds like 2 broken pieces of steel snapping past each other. frame is o.k., leaf springs are o.k. , doesn't do it when shifting between gears or if I gently take off from a stop. I don't think there's a grease fitting for the driveshaft where the splines are (where the 2 piece shaft takes up slack for being loaded or unloaded) may have to take that apart once the weather breaks and see what i find. my 1st ranger never had this issue after 200K miles. this truck is now at 145K but its almost 20 years old. I've read somewhere before about pulling the shaft apart & greasing the splines up. does this sound like a possibility for whats happening? not sure what else it could be.

We've been happy owners of a 2012 Prius C for about 9 months now. We've recently noticed some type of heavy metal clunking, like something in the engine compartment fell off. This is happening at least 3 times a week and happens at stop lights or even, most recently 3-5 minutes after the car has been shut off. We plan on taking it to the dealer this weekend to check, but know that it will be impossible for them to replicate the noise as it isn't a persistent issue.

I'm getting some heavy clunking from my passenger side wheel area, when I move the wheel side to side. I am almost positive it is the ball joint.

I'm having an issue I cant seam to track down. I am getting a bad clunking sound from the right side while taking a right turn. I was thinking it was an axle because it was flopping around when I took it out to inspect it. So I replaced that and also the ball joint because it was ripped. Took the car for a test drive and still getting this banging sound. I went back and checked the suspension bolts, tie rod, and cant seam to find my issue. I know bad wheel bearings make more of a howl but could they also make a bad clicking sound? or do you think the issue is worse than I was thinking and might be the diff?

I have a 1998 Ford Ranger, 3.0 4X4. Purchased in early 2002 with a clunking problem which has not gotten worse or better. When I take off it is a heavy double 'clunking' like something shifting and the settling. I have had 4 mechanics look at it, have changed the front u joint and have had the motor and transmission mounts checked but the mounts are OK. Can't figure this out. I talked to a person at a local car parts store and he mentioned that it could involve the 'yoke' and that it just might need to be greased but he was just guessing.

Under heavy acceleration my car surges. I have already put a new stock diverter valve on and no change....I am thinking n75 is next on my shotgun list?

I just went APR Stage 1+ (APR hpfp plus VWR intake) and am loving the noticeable power gain from Stage 1. But under hard acceleration I'm getting a strange noise (sounds like wheelspin or tire screech and sounds like it's coming from the front tires) when I disengage the clutch to shift at higher (5K+) rpms. It is not metallic sounding (it sounds like burning rubber) and lasts for a split second then goes away.
For those of you who've had tuned GTIs, it essentially sounds like what my Stage 1 GTI sounded like when too much torque was going to the front wheels and I spun my wheels before I got traction.
It doesn't happen as I re-engage the clutch and it doesn't happen any other time (quick but not WOT acceleration or normal driving). It also didn't happen under hard acceleration before I went from Stage 1 to Stage 1+. Furthermore, I'm not having any issues with difficulty shifting or engaging gears at any time. My R is 1 month old and has ~1K miles.
I've searched the clutch/transmission troubles thread, and other threads, but haven't come across other sounds/symptoms that seem similar.
At first I was thinking it was just a split second of wheelspin from too much torque as the AWD kicked in, but that doesn't seem to make sense (or does it?) since it only happens when I'm disengaging the clutch. Any thoughts before I start thinking the worst?

I have noticed since day 1 of owning my v8, that there i a horrible sound that comes from the exhaust upon medium to heavy acceleration - a loud fluttering is the best way i can describe it. I took it to the dealer and one tech said something was definitely wrong, the other went and got a new reg off the showroom floor and demonstrated that it is common and normal. Although another new reg did the same thing, i am not convinced that this obnoxious sound is normal ...

Here's the story on my truck. Spits and sputters between 40-60 during heavy acceleration and on rare occasions will jerk/pop while at a steady speed. No engine or wrench lights. I thought it might be the fuel filter and changed that, it didn't work. I also ran two bottles (on 2 separate occasions) of Duralube extreme fuel system cleaner, that didn't work either. So, I took it to the Ford dealer for a diagnostic. They had a hard time getting it to act up but said it finally misfired on #8 and recommended replacing the ignition coil and plug. I did that, still have the same symptoms. So, I thought it might be the fuel injector and changed that. Still same symptoms and ZERO dummy lights.
After several YouTube videos, I thought it might be the TPS and got one. Before I changed that however, I cleaned the Mass Air Flow sensor, still same symptoms. I finally changed the TPS, but the engine wouldn't start or run at all, no warning lights yet. When I put the old TPS on, it would run. I unplugged the TPS and it still ran but very rough. Now the engine light IS on! Thinking I purchased a bad part, I took it back to O'Reilly's and they warrantied it out and gave me a new one. I had 19 PO codes. I changed the TPS again, and, it won't start or run at all. Put the old one on and it runs. They cleared the codes and told me they think it could be the ECM/PCM.
Why will a new TPS not work? I still have the same issue of hesitation @ 40-60 during hard acceleration. No hesitation during a moderate acceleration.

My 03 Passat is going in for 40k service this week. I think they're going to tell me I need new brakes and rotors (felt some pretty heavy vibration during braking in the Tennessee hills). I was thinking of changing the front brakes myself. My mechanical abilities are modest, but I've done the brakes on my 94 Ford Ranger before.
1. Is this an easy task?
2. What parts will be needed?

When I am accelerating heavy and then slow down as it is engine braking i get a strange vibration. It seems to come from the drive line i just looked over the car today there is nothing loose all suspension is tight drive shaft looks good and the rubber u joint looks good too. I noticed it after I put in the resonator delete but I didn't think that it could cause it.

2005 2.OT ... Our car showed an engine light last night and when doing heavy acceleration, starts to pull or hesitate. Do not occurs when accelerating slowly, all day at dealer and they said that might be cam wear or some pressure pump. They are taking the engine covers to find out what is the issue. Cam repair and oil change. It drives smoother and no longer hard down shifting....
