With my car sitting, out of gear or clutch in, I rev the engine to say 4 thou. As the engine decelerates I get a perceptible vibration or shudder. It feels like an out of balance. In gear, accelerating, no problem. In gear, decelerating, no problem. And it doesn't happen all the time. It does, or doesn't do it hot or cold.
View 10 RepliesI drive a 2008 Elantra automatic,and have a constant engine shudder/vibration whenever the rpms are between 1000 and1500. The engine shudder stops as soon as I accelerate above 1500 rpms,or take my foot off the gas completely.
The dealer recommended cleaning of the fuel injector system,not sure if thats the course to take.I do know my model has had fuel pump issues,but the dealer has told me all recalls on the car have been processed.
New Sonata GL owner. Just picked it up last week and I love the car. Great drive, great features. Only thing is I am noticing that there's a humming noise from the engine whenever I accelerate and when the car decelerates. It's not really noticeable during the day when the streets are busy and I'm listening to the radio etc., but at night when I'm driving on quiet streets its quite audible and it almost sounds like Diesel engine.
I read a few threads on this and people have attributed it to the direct fuel injection - is this humming sound normal? Do all sonatas sound like this? Or should I go back to the dealership and get it checked out?
While braking, the car is revving up to about 1500 rpm and causing the vehicle to shudder and buck as if it wants to take off with no throttle input. The car is an automatic and this is the information relayed to me via my sister.
The car is a 2002 Jetta 2.0 automatic wagon.
On our trip to Daytona this weekend I noticed a vibration/shudder between 45-55mph. Above and below that range it doesn't happen. Dont feel it in steering wheel or pedal. Does it in both 3rd and OD. Got under truck and driveshaft doesn't move at all. Just got those new tires put on a couple weeks ago. Don't remember this vibration before that.
Just checked tire pressure - front right 48 psi. All the rest have about 45 psi, would that do it? I have a shudder in brakes from stops above 45 mph I'm assuming warped rotors, could that do it?
I have a 2002 Camry, V6 1mz-fe with 110k miles, recently developed a vibration which only occurs on acceleration, consistently noticeable at 2100-2500 RPM during acceleration. Acceleration above or below this RPM range is smooth otherwise. Coasting and braking are smooth. This vibration has never happened on the car before, which has been smooth all 110k miles prior.
The vibration was initially pretty bad, felt through the car, steering wheel, floor, and seats. I have since replaced both CV axles and wheel hub bearings, with some improvement. Also got new tires and wheels are fine. I replaced a bad dogbone engine mount at the top passenger side a few thousand miles ago.
Other considerations at the moment include bottom engine mounts, since my dogbone went out before. Other Google search suggestions include spark plugs, exhaust pipe bracket, transmission mount(?).
What could cause such an RPM specific vibration/shudder?
Has any ls600 owner noticed a small vibration/shudder when they decelerate (without braking) on the highway ? It may be only a hybrid issue even during normal operation as the electric engine are recharging the battery.
View 14 RepliesI have a 2004 Nissan Frontier with V6 non-supercharged engine, 4x4, with manual transmission, 150k miles. For approximately the last 30k miles, I have had a persistent shuddering in the cab when I apply the brakes slowing from about 15 to 0 MPH. It is accompanied by a low humming noise that decreases in pitch as the truck slows down. It only happens when the brakes are warm; about 70+ degrees outside or after I've been slowing down a lot. It does not seem to correspond to engine temperature, only my perceived temperature of the brakes. There is no pedal feedback, and it does not shudder when I stop using only the parking brake. It does not seem to affect stopping distance.
I first tried to fix it by doing a very thorough front/rear brake job - new pads/shoes, new rotors/drums, and repacked front wheel bearings. That had no effect on the problem. I tried rotating the tires and that had no effect. I then did a complete front end job and replaced all the bushings and balljoints via brand new pre-assembled control arm assemblies. I also replaced the tie rod assemblies, sway bar bushings/end links, and had an alignment done. That had no effect.
Based on the repairs I've done, I would assume that it is having to do with the front brakes, but is not warped rotors or anything in the front suspension.
Picked up a used 10 prius iv with 31k and have put 1200 miles so far. One troubling thing I have noticed is this weird shudder/vibration that occurs between 30-40mph when the throttle is at the half way point (area between the light green and dark green bar) Vibration similar to that of driving over the rumble strip on the highway but not nearly as harsh and the noise would be similar to when you have one rear window open in the car and it creates the pulsating wind noise.
It doesn't do it all the time and mashing the throttle seems to alleviate the problem. It doesn't happen so much when cruising around town but it happens every time I get near the top of the incline in our office park and the car continues to lose speed until such time as I get back on the gas but it continues to do it until I turn into the parking lot. Occasionally it does it when coasting down a hill with the throttle right near the point of crossing from light green to dark green on the screen.
I have a 1999 F-150, 4.2L V6 with 206,000 miles that recently developed a rear-end shudder/vibration. According to my door jam axle code (27) and the axle tag (3 37), I have what appears to be a conventional rear differential, even though most of my research would indicate this rear-end is for the F-250. In any case, and based on other online research, I changed the differential oil with a 75W-140 synthetic and added 4oz of a friction modifier. Now the vibration appears to be worse. It primarily vibrates when taking off from a stop, whether turning or not.
I have felt the vibration at speeds up to 60mph, but it is more noticeable at lower speeds. The vibration also seems to diminish after driving the truck for longer periods of time, particularly if at highway speeds. In other words, when I drive to and from work, which is about 30 minutes each way of mostly highway, the vibration is barely noticeable once I exit the highway and slow back down to 35-40mph. When feeling the vibration, if I decelerate, the vibration immediately ceases, but starts again when I accelerate. It's not as noticeable if I accelerate harder, but I generally don't do that. The gears inside the differential didn't have any noticeable wear, chips or slop/play. What may be plaguing my usual trouble-free F150?
I was wondering if brake vibration and shudder (all the way up to the steering wheel) could be caused by some loose joints and bushings in the front end suspension (like ball joints, tie-rods, etcetera).
Is it normal to grab a hold of the outer tie-rod end and to be able to twist it a bit? I have a vibration problem when braking, but I am thinking it has nothing to do with the brakes. I am thinking it is something abnormally loose on the front-end suspension.
Been doing a lot of reading about shudder/vibration on the 2011+ F150's and it seems to all center around the two piece driveshaft found on the longer wheelbases and more during take-off than other times. I have an '11 5.0L 4x4/auto with the 145 wheelbase and the 1-piece aluminum driveshaft and am experiencing a shudder in 3rd gear primarily, most noticeable during light acceleration with medium load (like gently accelerating up a slight incline).
When this is occurring I can see the tach needle fluctuating just slightly (maybe 50-150rpms, just barely bouncing) but I have no check engine light and the only time I have take-off shudder is under hard acceleration which feels like axle hop (which isn't too rare on soft leaf springs with 360hp engines!).
Anyways, this 3rd gear shudder is very soft and nobody has noticed it that has rode in the truck with me, but it sure feels like the old AODE/4R70W trans would when the fluid was getting old and the TC started to shudder during "soft" lock. 5.0L? Certainly could be a miss, though power is good, mileage is great and no CEL is lit...
2010 Corolla 1.8 automatic. Accelerating at highway speed (2800-3200) rpm a low frequency shudder/vibration is felt in the floorboards. Goes away of you let up off of gas pedal. No vibration at idle, runs fine all other times. Most noticeable when accelerating under load (ie going uphill) and at highway speed. Trans mount visually intact. Ditto engine mounts. Cv axles less than 1 year old no rattle upon shaking.
View 5 RepliesI now have an '01 Mountaineer with AWD and the 5.0. I have a strange vibration that only seems to happen when I accelerate as I get on the highway. I get up to speed and just as I let off on the throttle I get a vibration/shudder from the rear. Almost as if I ran over the rumble strip on the side of the highway. It's a short grrrr, then it goes away.
View 2 RepliesDriving into work this morning, I came up to the first stop sign before I get on the "freeway" and noticed a weird vibration. As I slowed to stop I could have sworn it felt like the engine was being lugged, the same feeling you get in a manual when you try to come to a stop without using the clutch. I thought for sure the engine was going to die. The engine RPMs dropped to about 800-900 RPM and once I got to a complete stop the RPMs went back to normal.
It seemed to do this every time I came to a stop. Could my torque converter be locking up and not releasing as it supposed to causing the lugging sensation I'm getting? The truck accelerates fine and idles fine once stopped, but when slowing I get that weird vibration and maybe the lugging sensation is just in my imagination and has nothing to do with the engine.
I do have a vibration from a missing wheel weight, but that's usually felt at about 34-35 mph. In addition, I also have a bit of a brake vibration when slowing down quickly, such as when slowing quickly from 65 to turn off the highway onto my local road, but this is a completely different vibration.
So I'm getting a mild to severe shudder depending on load and acceleration rate from stop to 10-15mph... It's worse if I'm on an incline...This has started since having a lift installed...I'm guessing it has everything to do with pinion angle...right?
1999' F350 7.3L 4x4
Crew Cab Long Bed
I just bought my 2015 F350 long bed Platinum a month ago, and the first trip with my 12,000 lb. 5th wheel had a vibration when starting out, but only from a stoplight with some acceleration or an incline, not at level slow startup.
View 6 RepliesMy 2015 F-350 Super Duty has a noticeable vibration between 5 and 15 mph when accelerating with my 5th wheel. The 5th wheel is heavy--around 14000 pounds. The pin weight is heavy--around 3000 pounds. The Owner's Manual says on page 191 "When driving with a trailer or payload, a slight vibration or shudder may be present due to the increased payload weight..." (This was brought to my attention by my dealer.)
Seeing the thousands of F-250 and F-350 Fords pulling 5th wheels out there on the road, I wonder how many have this "slight vibration or shudder" and what they have done about it.
I have this bucking a jerking when pulling my Sundowner LQ horse trailer, primarily in the 40-50 mph range. I can let off throttle and it stops but resumes unless I feather the throttle.... 2008 f 350, 4WD, 6.4, 48k miles....
View 1 RepliesLate build 03 f350 auto, I got a p0500 code and noticed sometimes after 2rd-3rd gear engages theres a shudder or fast vibration for few secs unless i let off, it didn't start this till i took batteries out, where is the location of the vss at, I am seeing some say at each wheel, on top rear diff, on top back of trans so not real sure?
View 7 RepliesI have noticed a moderate engine vibration at 1500 rpm on my R32 2008, but if you go to higher or lower rpm you cannot feel it anymore. I thought it could be a missfire, so I checked all ignition coils and changed the spark plugs but without improvement. Could it be the engine belt pulley?
