Ford Excursion :: Vibration Frequency Increasing With Speed
Jun 11, 2012
Had a long trip with the X this week and noticed a weird vibration up at speed. Anything before 65 mph and the truck was smooth, higher than that a medium vibration developed. Its frequency increased with speed. Never got the truck over 70, but the vibration was there enough to rattle change in the cup holder and the rear view mirror. What it might be? I was thinking a hub bearing... 2000 Limited 4x4 PSD ....

I have a relatively new to me Excursion. It seems to run well and shift well but recently I've become very aware of a strange hum, thrum, and vibration in the floor boards. The sound and vibration have a definite cadence/pulse.
Here is what I have observed trying to source the sound. Occurs around 2500 rpm and continues up to 4000 haven't really gone past 4k to know about after that.
Occurs in Park, neutral and drive and is more noticeable under load especially when towing. It is not really noticeable under my normal driving style it gets lost in the running gear until the X is at around 3600 RPM's which typically doesn't happen unless I'm pulling a long grade with a trailer. It was only after testing at a standstill in park and neutral that I realized it actually starts at approximately 2500.
Other than the vibration and low frequency hum starting at 2500 there are no real indicators of reduced performance or other problems but it's got me nervous.

My Prius v has 1300 miles. I didn't notice at first but now I notice a constant high frequency vibration in the car, especially at highway speeds. Took car to a tire shop and had tires dynamically balanced, same problem. I think it must be the toyo low profile tires or its in the drive train and just inherent to the hybrid system. Seems to be the same whether in eco mode or ev. Vibration is the same on smooth or rough roads. Dealer service manager says he is not aware of any problems. Suggests bring car in for a test drive and compare with another new one.

I am wondering if the frequency of the signal to change lanes can be increased from three (3) blips to four (4) or five (5) blips. Mine does only 3 and sometimes I do not find that sufficient - maybe I like to be extra cautious.
I have a Ross-Tech VAG-COM so looking for any way of changing it using that tool. I just do not feel very inclined to go around changing parameters without knowing what the outcome may be. I find the Ross-Tech manual to be rather cryptic.

Over the last several months, the frequency with which my 2007 Subaru Outback is "shuddering" when I accelerate from a stop has been increasing. It feels like driving over a cattle grate -- a vibration that lasts for just a few seconds, and occurs in the 35-45 mph range. Now is happening on a daily basis, a couple of times per day. Based on some internet searchers, I concluded this might be a torque converter problem. Took it to the mechanic today and, of course, couldn't reproduce the problem with them present. They replaced the transmission fluid with a synthetic fluid and replaced the transmission filter.

This is on an 04 Excursion, 4x4, 6.0 SPD. I have started experiencing a vibration at highway speed, 60-70 mph. After 70 it smooths out a little but still noticeable. I've replaced both rear tires and still have the issue. When I put my foot on the accelerator I can feel it more but as soon as I let off it drops off dramatically. I am thinking u-joints, which will be replaced this evening...

I replaced the motor mounts, and now there is a vibration at speed (70 or so). I've taken it to Michigan and back, so it is probably broken in. Can these things be put in improperly?

1999 (built late 1998) Ranger 2.5 stick 2wd single cab. If I get much over 75 MPH the speedometer will reverse direction despite increasing speed. If I then let off the throttle completely, the speedo will jump right back up and indicate the correct speed. Continued operation without letting off the throttle to let the speedo recover will trip the ABS fault light, probably due to the erratic signal.
Disconnecting RABS module has no effect on symptoms. Speed sensor in the rear axle has been replaced already (by me) and the new unit ohm'd out good. Wiring between GEM and sensor checks out as well, good continuity (< 1 ohm) and no shorts to chassis ground. I wish I had an o'scope to take a look at the waveform, but I don't at the moment. It is on my future tool purchase list.

Just got my 2014 SCREW 6.5bed with eco boost. Truck has a high frequency vibration very noticeable at 45-55 MPH. So bad the rear view mirror is blurry. Took it to the dealer and they said the e-brake was dragging and fixed that and said the vibration was gone. Not gone. Did some searches and found a number people reporting vibration issues possibly related to drive shaft issues.
Took this video of the slip yoke at the T-case idling in first gear, sent it to the dealer and they said that's normal. I don't think that looks normal. Does that looks normal?

Today i wanted to slow down a bit after hitting 75mph on a 65mph freeway so i stepped off the gas pedal. However the speed did not decrease but kept going up slowly to 80 till i stepped on the brake in order to slow down. After hitting the brake , it seemed to work as usual ( speed decreases when foot is pff the pedal). Had to do it multiple times today? Am i missing something? Only happened on the freeway, once i got off it seemed fine.
2014is 250 f.

Had the front end axle replaced due to a boot that was ripped on the CV joint. Three months later the front end is vibrating while increasing speed and passing. The shop is telling me its my transmission?! Doesn't sound right to me. So i take it to another shop and they say its the axle. Okay its under warrenty but the other shop says its the transmission.

I have a 2007 Ford Fusion SE 2.3L 4 cylinder. It has approximately 94,000 miles on it. I purchased new Sumitomo tires with a 100,000 mile warranty in February of this year. They were balanced and aligned at the time of install. So far they have been very smooth and quiet with great grip. About 2 months ago I started hearing a noise that sounds like uneven tire wear, a sort of rhythmic rubbing or wobble sound that increases in frequency as the speed increases. It is most noticeable at speeds between 30 and 50mph. I rotate the tires every other other change (at least twice a year) and had the alignment done again in late October. I am hoping that there is nothing wrong with my virtually brand new tires. Is there anything else it could likely be?

I have a 1993 protege that was previously not having any issues. I recently had a mobile mechanic replace my axle after it broke. Since then I have had issues with the rpm's increasing but the speed staying the same or decreasing. This happens mostly uphill and especially when the vehicle is cold. Is there another reason this can occur besides a bad clutch?

I have this noise that is cumming from under the car about dead center Engine area its only heard while driving and more as the car has been driven for some time. From speeds 20mph and above only when increasing speed or when full throttle. It wont do it in park or revving it i jack up the car front end and put in drive only front right tire turns but still no noise(is there away for the left tire to turn). Everthing works normal the noise is low and at times only.
2.4L Sonata 68000+miles.

Well Prii have always been a little "loud" under acceleration due to the CVT and small engine and minimal sound proofing, BUT We have 2 Priuses (Prii??), a 2011 with 41000 miles and a 2014 with 7k miles. My daughter got the 2011 to take to college. 1200 mile round trip so it made sense.
She maintains that for sometime, the 2011 is making more of the droning/roaring sound that a Prius makes when accelerating briskly. I did not really believe, her, but over holiday break, I had the opportunity to drive both cars more, and she is right.
The 2011 is clearly louder under acceleration. It also will develop a bit of a vibration at certain RPMs, even at very low RPM sometimes, when the economy bar is just beyond the electric mode.
The noise differential between 2011 and 2014 is most apparent at cold temperatures, but it does not resolve completely even with both engines fully warmed up.

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.

I have a 2015 RX350 with 25k. New tires, two road force balance by two different dealers and I'm still getting a high frequency vibration mostly in the seats above 60mph. Dealer cannot find any issues.

I have a rear wheel bearing type of noise that appears to come from the rear. My vehicle is front wheel drive and has 135K miles.
I checked the rear wheel bearing/hub assys on both sides and they had no play but I changed them anyway. Noise did not change at all. Rear tires have normal wear, no cupping or anything. Noise gets louder with increasing speed up to a point and then remains a constant level.
My next thought is to check the front wheel bearings/cv joints.

After driving for 30 minutes on the freeway, my Sonoma develops a high freq vibration that seems to increase after it starts. lessens a little as I slow, but does not go away until after the car has been parked for a while, but not as noticeable under about 30.. I have experienced this the last three days on my commute to and from work. Did have the breaks checked. I did have a clunk sound when i released the brakes at a stop, but that went away after the first brake check where they did not find anything, but just cleaned out the dust and readjusted. The vibe is pretty strong and makes me nervous to drive.

I own a 99 Toyota Camry w/ 122k miles on it. About a year and a half ago I started hearing a low frequency vibration coming from left rear. A few mechanics said it was a worn bearing and I may want to get that fixed in near future. Well here it is 2011, I can't stand the sound anymore and am concerned what other damage (if any) I may have put on my car.

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.
