Prius (2010-12) :: Car Jerks When Letting Off The Accelerator

Our 2010 Prius jerks at speed of 15-20 mph and or when letting off the accelerator. I changed the spark plugs & filter. Also, cleaned out EGR tube, throttle body and intake manifold. thinking these might be it. These did make minor improvements, but the issue remains. No codes.

Touareg :: Thumping / Knocking Noise When Letting Off Of The Accelerator To Stop

I have been hearing a muffled thud or knocking noise often, especially when letting off of the accellerator when coming to a stop...almost sounds like some kind of bracket might be broken and some part is slapping against another. No particular consistency in the pattern of the sound...very strange. I had the car in for service to replace the stepper motor and the tech indicated he thought changing it would take care of it...it didn't.

Ford Excursion :: Driveline Clunk When Going Over 40mph And Letting Off / Reapplying The Accelerator

I've got a pretty nasty driveline clunk when going over 40mph and letting off and reapplying the accelerator. The way I'd describe it is: when I let off, it feels like something clunks forward, and when I get back on it, it feels like it clunks backwards.

So far I've had the U-joints replaced, replaced the tranny mount, greased the slip-yolk several times, and just changed the rear diff oil (and found no broken teeth or excessive wear in the gears) and it still does it.

Since I don't have a sig:
2001 Ex 4x4 7.3L PSD
5" RC Lift (but the clunking was present before the lift)

Ford - Explorer :: 2004 - Rumble From Rear Of Vehicle When Letting Off Accelerator

04 explorer, When traveling under throttle the thing runs smooth, when letting off accelerator, there's a rumble from, what seems like, the rear of the vehicle, when I press the accelerator, it almost "clunks" and acts fine once it's under acceleration again. Should I suspect my rear end gears going out, or something simple like a universal joint.

Prius (2010-12) :: Slight Hesitation At Slight Acceleration Or Constant Speed

I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.

Ford Super Duty (1999-2016) :: 2002 F250 - Vibration When Letting Off Accelerator

So, I'm slowly but surely eliminating a terribly shaky front end on my 2002 F-250 7.3L 4x4. First was a new carrier joint on the front drive shaft. Didn't work much, but the shop said the darn thing was falling apart. Next thing I did was new wheel bearings and manual hubs. Less vibration for sure. But the last remaining issue, in terms of vibration, is that when I let go of the Accelerator going at any speed above 60 MPH, it makes a horrible horrible noise, and I could feel a vibration. It shakes the whole truck, but I can very noticeably feel it directly in the gas pedal. It's really only an issue during deceleration. What could it be??? Drive shaft U-joints? Torque Converter? Something else in the Front End? Something in the engine even?? I don't exactly have the funds to tackle every possible solution.

Touareg :: Slight Vibrations Over 80km/h

So i got V6 3.2 with air suspension, when i purchased the car there was TONS of vibrations in the steering wheel and i could feel it also in the seats, but i knew this was unbalanced tires and stuff so i made a deal with dealer that they should fix vibrations. They balanced tires and thing went away but not completely. Over 80km/h i get very very little vibrations in the seats, i can feel it in my legs and a bit in the steering wheel. I have Nokian tires (those that are recommended for touareg, forgot the model) and they are pretty worn out but nothing to be concerned about, i took a look and they seem to be worn out pretty even, dont think there is alignment problem. What else could we look at?

Ford 6.0L Power Stroke Diesel :: Slight Whistle / Squeal When Boosting And When Letting Off On Pedal

Are they known to cause any noise? VGT Solenoid.

I have recently developed a slight whistle/squeal when boosting and when letting off on the pedal. I initially thought I had a CAC boot starting to split out, but since it's making the noise when I let off as well I doubt that the problem.

It isn't constant, and only does it for a second or two when it happens. It's not extremely loud, just loud enough to make you wonder what the heck it is...

Golf V R32 :: Vibrations / Scrubbing When Making Slight Right Turns?

MKV R32? I take Hwy 17 to and from work. It's a pretty curvy road with some of tight turns (fun) and a number of slight turns that have a little incline. Whenever I make a slight right turn (like a long sweeper), I feel a slight vibration under the pedals and it feels like the car is grinding.

It only happens on those slight turns at 50-65mph and I can only replicate the vibrations on a curvier road......The car is smooth as silk around town, on the interstate but not when it comes to those right hand sweepers.

The car has no problem taking full right hand turns or even handling a right hand hairpin. Could it be my tires?wheel bearings? alignment?need my tires rotated? I took it to the dealer and the mechanic and I couldn't replicate the problem on the interstate. The car has 8900 miles on it and I will need to take it in for service soon.

Golf/GTI VI :: Slight Vibrations In The Seat And Steering Wheel Past 60 Mph?

Experiencing slight vibrations in the seat, and steering wheel past 60 mph on the stock wheel & tire set up? I've got about 10k miles on my Pirellis and am thinking that all the winter driving (potholes) have knocked them out of balance. The VW dealer claims they balance fine, but I can feel the vibrations. Just wondering how everyone else is liking their stock set up.. Maybe a wheel has a slight bend? Nothing I can notice from a quick glance tho.

Golf IV / Jetta IV :: VR6 5 Speed - Clanking Noise When Letting Clutch Out In Gear

The car runs fine clutch has pressure and everything. I can idle with the clutch pressed down and put into reverse and every gear BUT if I put it in a gear and start to let the clutch out I can hear a clanking or something flying around in there and it doesn't really want to go anywhere and I don't want to really let the clutch all the way out in gear or let it out for too long and screw anything else up worse..

Prius (2010-12) :: Slight Thump At Speed Under 20

About a month ago, I noticed a slight 'thump thump' at speeds under 20 and started thinking either tire or wheel bearing. Turns didn't seem to change the sound/feel but it always smoothed out over 30 mph. I could not see anything visibly wrong with the tires other than the front pair needed to be replaced. Wear otherwise looked normal. But Monday night, I needed to pickup my laptop computer at work and my wife and her two dogs came along.

It was midnight when we left but for good measure, I felt around the tires and could feel nothing. Overcast, storms were predicted and were on the radar west of us. We walked the dogs; got the computer, and; Holly said she'd like a nightcap. So we went to a local bar and had a good time. Got back in the car, backed up less than 2 ft and 'poof' a cloud of white power flew from the passenger side, front tire:

As I was getting the tire off, a brief 'sprinkling' occurred...

Prius (2004-09) :: Slight Vibration / Stutter Feeling At Low Speed

98k miles and if the car is on a slight incline and your backing up or creeping forward it feels like you are going over a rumble strip. that slight stuttering feeling. no codes have tripped. I've asked the toyota dealership and they don't know what could be the problem. The trans axle fluid was changed at 88k and from what i was told there were no metal shavings in the fluid. it was a little dark but after going 88k miles i assume it would be.

Golf VI R :: Whistling / Slight Rattle When Punch The Accelerator

My APR dealer is double checking on this. Got an APR Stage 1 tune today and am now periodically noticing a whistling/slight rattle when I punch the accelerator. Only appears to happen when I build revs quickly. Never heard anything like this before the Tune.

Prius (Gen 2) :: Slight Grating Noise When Loaded Up Left Front Wheel (by Steering Right) At Speed

I drove our 2007 Prius (79K miles) the other day and noticed a whirring or slight grating noise whenever I loaded up the left front wheel (by steering right) at speed. It's far from a hum or a howl at this point.

Bmw - 325 :: Whining Or Slight Howling Sound At 60 Mph When Touch Accelerator To Apply Power

I have had 2 cars with exactly the same problem. The first was a 1998 Volovo V70XC. And the second is my current 2003 BMW 325Xi - both AWD. When driving say on a freeway at 60 mph and you touch the accelerator to apply power, you get a whining or slight howling sound. As soon as you lift, the sound disappears, but each time you touch the pedal, the sound reappears. It seems to be coming from the driveline toward the mid to rear of the car. As you accelerate to 65-70 or decelerate to 55-50, the phenomenon disappears. What is causing this and how can it be fixed?

Ford Excursion :: 2003 - Driveline Vibrations Mainly On Highway Speed And When Slightly Press On The Gas

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.
