Ford F-150 - 1997-2003 :: Vibration Most Noticeable At 55 - 60 MPH
Dec 6, 2015
Have a 1997 2wd F-150 XLT auto trans with 305,000 miles that has developed at vibration that is most noticeable at 55-60mph. It seems to start at about 35, but at 55 you can feel it in your seat. When it's vibrating shifting into neutral doesn't change anything.
Drive shaft u-joints: two rear replaced not too long ago (5+ years?), front joint by transmission seems to move freely, but isn't excessively sloppy, carrier bearing okay. Have done the following with no improvement:
Re-balanced all tires, no problems noticed during the balance;
Replaced first right and then left rotor and wheel bearings, no change.
Several mechanics have driven it and made different pronouncements, it's not: transmission, rear-end, tires, u-joints or carrier bearing. One mechanic ran it while up on his lift and didn't see a driveshaft balance problem. Last suggestion was that the left wheel bearing were "on their way out", so they were the most recent change. It's drivable, but not fun and it produces a lot of noise in the cab.

I've got a 2002 F350 DRW 7.3 truck I'm having a little concern over. It started this summer, when under very heavy pulling I was getting a very noticeable vibration between 20 and 25 mph. I did not think much of it, as it only happened under extreme conditions.
Now I'm getting the vibration all the time, and it's started another band which is 40 to 45 mph. It's much worse if you are very light on the throttle, if you're full throttle it's much harder to notice.
Truck has 154,000 miles.

Just got new tires Friday. Now I have a very noticeable shaking right at 35-40mph. Doesn't do this at any other speeds and test d up to 80mph. Took back to where I got the tires and told them and they rebalanced them and yet it still does it. Could it be a bad tire? What am I missing?

My 98 F150 4WD with 83k on it has a significant pull to the right most noticeable on the highway. I have to keep the wheel turned to the left to be able to go straight. It use to be intermittent but now is constant. Had a frt end alignment done twice with no change. Recently after a long drive on the highway on a crazy hot day, I pulled into a rest area & noticed the L/F wheel was very hot to the point where I thought the plastic center cap might start melting.
The R/F wheel was only warm. This makes no sense to me because with something causing the L/F wheel to heat up I would think it would pull to the left. This has bothered me so much that I've driven with 10psi less in the L/F wheel hoping it wouldn't pull to the right so much but it had no effect. I did recently have the left upper control arm replaced because it was clunking. It was doing this pulling prior to that & it continues.

I have a 98 F150 Supercab 4x4 with 4.6 and an auto trans. I have 107,000 miles on the truck. Recently developed a engine "tick". Upon start up the "tick" is very noticeable. Seems to go away after its been driven a few miles and everything comes up to operating temp. I have checked the exhaust manifolds, all studs and nuts are still there. There are no noticeable holes that I could feel in the manifolds. Read some other posts here that have the "tick under load". Mine goes away once everything warms up. What to look at or for?

My 2001 4.6L F-150 has been sitting on the driveway, used once every 2 weeks or so for the last 3 yrs. I came to start it a few days ago and it kept turning over but not starting. The key security chip is working, battery is charged, all plugs are firing, fuel pump fuse and relay check good. When I turn the key to ON, sometimes I hear the fuel pump priming, other times it doesn't. The times it does prime, the truck fires right up.
The times it doesn't prime, engine won't start. When the pump does prime, and while the engine is running, the pump makes a noticeable buzzing sound, much louder than normal. When the pump primes. fuel pressure measures at 42psi in the ON position, 36psi with engine running, and 46psi with engine running and vacuum hose removed. I believe all these are within specs.
My question is this: Is it safe to assume that the pump is going bad and will eventually fail completely? My second question is (and I know this can be debated til the end of time) should I get the Motorcraft or aftermarket? I have Airtex, Spectra, Carter, and Delphi available locally.

We went to an out of town zoo over the weekend and the exit is going up a short but steep incline. When going up I get this very noticable shutter, vibration coming from underneath but thats the only time it does it. This is the 3rd weekend in a row weve been there and its done it everytime. Is there anything I could check? Normal driving is non issue, and going up this incline were only going like 5 mph or so. Im stumped.

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?

I just purchased my brand new 2014 F150 4x4 STX 5.0L single cab short box about a month ago. I noticed when I drove it off the lot that it had a slight vibration at low RPMs. I boiled it down to brand new stuff working out all the kinks and running around for the first time, bought a brand new jeep in 2005 and it made interesting noises and had funny vibrations for a while, but this is starting to get annoying. I have a very noticeable vibration at low RPMs both in park and while driving, more noticeable at speeds between 35-45 with RPMs anywhere from idle to 1500 or so.
I have not had it at the dealer yet, I want to be armed with a little bit of knowledge when I go in an talk to them if possible. I know how stealerships work and since it seems similar problems are somewhat common in these newer F150s, I don't want to get the "oh it's common in these trucks and perfectly normal". In my opinion a brand new truck should run smoother than melted butter on hot flapjacks, especially one that only has 1400 miles on it.

I had the ball joints and u joints swapped out in my Ex a week ago and something's been bothering me. I get a vibration when cresting 65mph that I can't pinpoint. It's not violent and it doesn't appear to be in the steering wheels as it's straight and not jerking at all. It doesn't really affect anything that I can tell either... it's not the vibration from out of balance tires or cupped tires, it's just enough to be annoying... and a concern.
I can't tell if it's coming from the front or the rear either... just seems to be a hum that I can feel that wasn't there before the repairs where done. Where to start?

The subject: F150, 2007, 5.4L, FX4 version. It has only 80K miles and was very light used by my sister. It seems to me come with a 4R75E ....
Recently I notice a strange vibration every time tranny downshift from 4 to 3, specially noticeable going uphill. Some times can be feel when tranny shift from 3 to 4th...
A friend in my town comment to us, this is a very common condition here because there are just small streets and avenues so that truck shift very frequently betwen 4 to 3 and then back to 4th...
Sounds like a excessive wear on a bearing thrust ??

My current 08 duty was bought with what I believe to be a procomp 6" lift modified to an 8" lift. The 100 mile drive home after buying the truck showed a tiny "hop" in the rear. I ditched the 37s for some new 35s. Still a tiny hop, mostly noticeable while under a load like climbing a hill. I pulled the rear driveshaft and had it fully rebuilt with a new carrier bearing as well. Still gots the hop? The truck has a carrier bearing drop bracket but I think it may be insufficient for the lift.
The rear driveshaft still has a slight bend in the middle of where the two driveshaft pieces connect. Are the 2 piece driveshafts on your 8" lifted trucks sitting straight with each other or do they have this bend as well?? I am thinking if I get a bigger drop bracket it may cure this slight hop I have? Lots of lifted trucks where I live but they are dam near all shortbox with 1 piece rear shafts so I haven't been able to find one to compare. By the way, my truck also has pro comp rear traction bars..

Vibration in my 2014 Prius v (lowercase for the Prius v wagon, not an uppercase) Three. It happens at all speeds but is most noticeable between 68-72 mph. It is felt throughout the car. I am about to go to arbitration with the state (Florida). I had a Lemon Law arbitration hearing with the Toyota sponsored program (NCDS), and the claim was denied. He said he could feel the vibration but it was normal vibration for highway speed. It was quite obvious he knew the Toyota reps too.
Toyota's solution to the issue at the "final fix" attempt was to install new Michelin tires and Road Force them. After getting the car back, I also found they had lowered the PSI in the tires to dampen the vibration but can't prove it. I put the PSI up to what is printed on the door and the vibration came back and got much worse after the tires were rotated.

The other day while putting on some highway miles on a smooth road I experienced some new vibrations. Not good vibrations, unfortunately. She is an 02 Leg Wagon with 115,000 miles. The vibration was low amplitude and relatively high frequency and was most noticeable at 65 mph or above. Although pronounced at the steering column, the vibration seemed to be throughout the car. Struts? Motor mounts? Imagination? I cant handle the truth?

I haven't really gotten under it to check this out, but my truck (see signature) has a slight vibration on take off. It only does it when the wheels are turned to the right or left. They don't have to be turned very far either. It doesn't do it on straight line take offs, or on a take off from a rolling stop. ONLY when pulling off from a dead stop and the front wheels are turned any degree to the right or left. I'm running mostly bald all terrain tires, the wheels are not bent. My current wheels are new to the truck, and the problem was there with the previous rim/tire combination. The rear end doesn't seem to have any slack in it. The transmission shifts like a top. There are no other clanks or vibrations anywhere in the drivetrain and it drives good.

The truck is a 1997 F250 light duty extended cab with the 4.6 triton v8. The motor appears to run smooth and idles good, from my perspective. It accelerates smoothly, as well, and seems to cruise at an otherwise smooth rate. Until I hit around 50. Then it transitions right into a shake, or vibration. I know I need to be more specifc with the symptoms here, but it's pretty hard to feel where it's coming from. I feel it in the steering wheel, but also, it feels like the whole truck. My dog, oddly enough, will look at the center floor with his head tilted, when it starts to vibrate, I know he's got a better sense of hearing then me.
So, up to about 60 and over that it seems to go away. Sink back down below 60, vibration is back. below 50, seems to go away. It does it in and out of overdrive, does it when I pop it into neutral, but when truck speed goes down below 50 or over 60 for the most part, under various said stimuli, the vibration fades away. I'll also add that the vibration increases substantially with greater acceleration...The more gas I give it, the worse it seems to get, but still, only within the 50 to 60 range. Not as bad when cruising and/or coasting, but still vibrates regardless. Otherwise, acceleration from dead stop and over 60 is good.
So far, I rotated the tires and only difference I noticed after this was a little bit of a shimmy at 40 to about 43 mph that wasn't there before I rotated the tires. They probably need to be balanced, but the vibration at 50 to 60 doesn't seem to be tire related. The 50 to 60 mph thing is more like an overall vibration. I'm thinking driveshaft maybe? I checked the u-joints and they seem pretty tight...no movement I could feel by hand. I also check the front end a little bit, and tried to see if anything looked or felt funny, like any excessive play in the ball joints or tie rods, etc. That all appeared okay.
So, for now, I just try to avoid 50 to 60 mph. Harder then one would think...you end up either getting tailed or tailing someone. I guess that's all for now. If you need more info, I'll try to get it to this post as soon as I get a chance. Also, not sure of the trans I have. You all probably know better then me, but once I get a chance to check, will let you know. I don't think it's trans related or torque converter. I am not slipping or knocking, but forgot to check the trans fluid, which I will also update the condition of that when I get a chance.
Also, engine seems to run smooth. I didn't change out the plugs or wires per what I would think normal maintenance, but have nightmares of doing the plugs and breaking one. especially on these tritons. I had a e350 with the 5.4? that blew a plug and stripped out the threads. This 4.6 doesn't look any friendlier to navigate, with the fuel rails in the way and all. But if that is the problem and needs to be done, well, I'll get it done if I have to. But, like I said, idles well and accelerates up to 50 fine...no ticking or unusual sounds, at least that I notice.

I bought 2012 Prius ii around 6 weeks ago. From day one I started noticing vibrations in the steering wheel most noticeable at highway speeds. I can describe this as high frequency vibrations that become very very annoying especially if you drive to work for an hour every day. This car has OEM Bridgestone Ecopia EP 20 tires. I took the car to the dealership twice already, they balanced the tires twice and road force tested it twice. They replaced front tires for me because based on the test results one tire was at 16 lb the other one at 19 lbs.
The new tires are at 8 and 10. They keep on telling me that this is by design and is a characteristic of the vehicle. However the Prius I test drove when I was buying it did not have this problem, otherwise I would never buy it. This vibration happens in any mode and I can even feel it at lower speed now though it is not as noticeable. I had a few people including Prius owners drive my car and everyone feels the vibration. With so many Prius models sold I highly doubt that everyone just accepts it as a feature.

I have an 01 passat and when I was coming home one night my car has gone over a pot hole or hit something. I checked the car immediately but couldn't see anything wrong. But as I been driving it there is a resonant vibration in the car that becomes noticeable at 80km/h and above. At low speeds it feels normal. But once I get up to speed I get this vibration and its not a side to side vibration just a constant shaking. Sort if like if I were going over a a road that had very very small bumps. My friend had a look at it and thinks that one of the tires are done. But he's not really sure. What may be causing it?

1999 F150 has a tremble or vibration between 27 and 40 MPH it does it in any gear but only between these speeds. I thought to begin with it might be a slight misfire, but seems like if that was the cause it would happen at any speed...

I have 2002 5.4L f150 120k miles. Bought it almost 2 years ago and did not notice this vibration at the time but it could have been there and I didn't realize it. The trans was replaced by ford with a reman at 90k. I'd assume they inspected the trans mounts but who knows.
At idle only, there is a vibration. Enough that I can see water in a bottle moving and a plastic bag shake., felt through the seat, hand on engine can feel it, can feel it through the door..etc. Very annoying. At 700-750 rpm it goes away. Happens in all gears. I don't want to shotgun approach this. What I've done: Replaced plugs and coils since it needed them anyway. They looked good! No difference. I've sprayed the maf down and cleaned the throttle plate (I know your not supposed to but some 16 year old will try to tell me it cured his idle and he gained 10 mpg, so I figured I would mention it). I've removed the IAC and cleaned it, plunger moves freely. My idle does not fluctuate. I have watched mode $6, it's not a misfire. I have removed the pcv hose and checked for cracks - it's in good shape. Replaced the pcv since it's cheap. Ran Chevron tehcron through it. Checked codes - nothing. I have an edge and it happens on all tunes as well as stock.
I have ability to read live data but do not know enough to interpret it, so that is about useless unless you can provide me acceptible ranges.

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?
