Ford Excursion :: Vibration When Accelerating From A Stop Up To 40 MPH
Sep 20, 2013
I have a noticeable driveline vibration when accelerating from a stop up to 40 m.p.h., after that speed it goes away. I have driven it up to 75 m.p.h. on the highway with no vibrations at that speed. It only does it from 0-40. I have checked the u-joints and driveshaft run-out and all is good. The truck was lifted 6" by the P/O. The pinion angle looks too high to me. (It has 6* shims under the springs).Front u-joint angle is 1/2*, while the rear is 2 1/2* in relation to the driveshaft. If this is the case, wouldn't the vibrations get worse, not better, when speeds increase above 40 m.p.h.? What else to check???

When accelerating from a stop, I get a clunking sound from the front end. I took some pics of the sway bar and I think it maybe loose. There is a gap between the bolt between the bar. Is this normal, or can I tighten it with the X on the ground or does it have to be up on a lift to properly tighten?

My F250 6.4, 3.73 Crew Cab Short bed vibrates when accelerating from a stop with my 5th wheel on. The 5th wheel weighs 12K. It is a medium to high frequency vibration that is felt throughout the entire truck. It continues through the shift into 2nd (TorqueShift Tranny). The harder you accelerate the more you feel it.
It does not occur if truck is unloaded and you accelerate at full throttle. Is this normal or should I get it looked at?

I have a 96 ford escort, 1.9. Recently I've noticed I get a pretty good vibration coming from the front end.
The vibration only occurs when I'm accelerating over 50. When I decelerate over 50 the vibration goes away.
What could be causing this?

So I have a 2016 6.7L love it but it has this vibration at 65 mph that is worse when accelerating up a hill. It feels like an out of balance wheel but I have had them balanced 3 times. road forced 2 times. My dealer replaced the driveline also. I did a test with 400 lbs of concrete bags in the bed and it was vibration free. It almost is like the pinion angle is off.

I've been living with a mild "clunk" or "bump" in the drive train when I would first begin to accelerate from a full complete stop. It would only happen after a complete stop. It almost felt like it could be normal, but it seemed to be getting worse over time.
At first I thought it was my transmission...but after some internet searching I found some threads talking about the slip yoke on the drive shaft being the cause. In that the slip yoke needs to be pulled apart and re-lubed.
Anyway, I thought I'd post and let eveyone know that after pulling the slip yoke and re-lubing with grease my issue is solved! The "clunk" is totally gone. 100% Smooth now. If has this issue I'd highly recommend re-lubing the slip yoke.

On my 2004 F-150 SuperCrew, all I needed to do was remove the drive shaft at the rear differential (4 bolts, use 12mm 12 point socket or wrench). Then remove the FRONT clamp on the slip yoke boot. Then slide out the rear 1/2 of the drive shaft. Be sure to mark the drive shaft orientation with the rear differential flange and the slip yoke before you remove the drive shaft to ensure you put it back together correctly.
Re-lube the slip yoke, then slide it back together and reinstall the four bolts at the rear differential. Torque spec is 76 ft-lbs. I used Valvoline FORD-LINCOLN-MERCURY moly grease that I purchased at my local AutoZone. You'll also need to install a new band clamp around the rubber slip yoke boot. I got mine from AutoZone.
Here are some links I found with pictures showing how to do this. Both procedures below are on SuperDuties but its basically the same procedure. Just follow my specific details above for the 2004-2008 F-150

After changing out my tensioner on my 6.0 but not directly about 24 hours later I started getting a surge/power/smoking problem after accelerating. Seems to be no problem at idle. Last night driving from Nj to SC it seemed to do it after I stopped to pee. If I could get it back to 60-65 mph it would run fine but accelerating to there was rough. I change my ebp sensor and thought that solved it but it came back. Unfortunately I couldn't get the sensing line off so that wasn't cleaned.
Unplugged the egr and thought that did it but it ended doing it again. When looking at the dashboss it looks like exhaust pressure goes up and boost goes to zero. What would cause the guide vanes to close is that a defuel or is that just the result of another sensor. It's a late 04 build with ipc on valve cover and ebp sensor at front of engine. Also it seems to happen at higher speeds. Going up and down hills at 75 or even 70 it seemed to do it often. I ran 60-65 between pee stops for hours without a hiccup..

My 2005 ford freestyle (fwd) has a creaking noise when accelerating from stop and turning left but not when turning right. It's been there for a while. I had a problem where front left wheel felt loose. Replaced struts no change. Replaced left front wheel ball joint and fixed that awful feeling, but it still creaks.

I have a 2010 F150 Xlt super crew with a 4.6L. I've noticed lately when I start from a full stop the the truck has a small shutter or hesitation before it starts accelerating. Its barely noticable but it is there. What it could be? I had the tourque converter replaced just before my warranty was up, I've only put 30000 Km on it since. Was wondering if it could be the cause.

I'm the original owner at 50k miles with Ford ESP warranty. Drive-train still under original warranty. I started noticing a low growl hum noise and vibration felt on gas pedal when accelerating at about 40 MPH. At first I thought it was the road or tires.
Then a few weeks later on a slight hill the growl-low hum was accompanied with a much more noticeable/louder growl/grinding noise in a heartbeat like rhythm. Took it to dealer and they first said it was the transmission. It was replaced.
Then they said the noise was from the rear differential/axle. It was rebuilt, oiled and sealed. Taking it back today for another drive with the mechanic to show them again the problem persist. What it may be? Also, my MPG has dropped significantly from an average of 18 to 13. This is while driving on 4x4 Auto.

2001 v10 ... I have a thumping noise under acceleration... also hear it if brake torquing.. i do not hear the sound if in park or neutral...while riding down road the sound goes away when you let of the gas. Torque converter has been replaced.... exhaust manifold bolts are ok too. Been to 3 places and no one can seem to pin point it or no where to begin.

I have a 2007 Ford Fusion 4.0L AWD. One day I went to pass a slower car and accelerated rapidly, but the car responded with loss of power and shook to a stop and would not re fire. I took it to the dealership and they said two cylinders were not firing and a fuse was blown. I looked on the internet and some people said their coils go bad or plug wires. I asked the dealership if that was the cause and they said absolutely not, but it's the ECM. They replaced the ECM and 2 days later my CEL came on and I took it back to the dealership and they told me my catalytic converter was bad and I could drive it until I had the money to replace it. Then a couple days go by and I was passing a tractor on the highway, I slowed down to 45 mph to make the pass and as I began to accelerated I felt a thunk, then about a mile later it started cutting out and shaking. This time it would re fire but idle rough. I tried on/off 3 or 4 times then it idled o.k. I then took it back to the dealership and this time they said it's all 6 coils.

F250 5.4L have had a new fuel pump installed and new spark plugs (one blew out). When accelerating, or at a stop i get a kinda hesitation. It did it when I first bought the truck but put correct size tires on it and it went away. What it may be? I don't have a check engine light or anything and at cruise speed no problem--it's just when a slight load is put on the engine?

My '05 F350 PSD has developed a pretty bad vibration most noticeable above 40mph but only under acceleration. As soon as i hit speed and let off the gas its gone but if i accelerate again to pick up the speed i lost its back. Haven't looked into it too much yet as i was busy all weekend and drove the Expy but I did get down there and don't have an obviously bad u-joint or carrier bearing. I'm also gonna see if i popped off a driveline weight or something.

I've finally found the elusive and annoying rattle under my '00 Ex V10. It only rattled while accelerating and at non regular times. I searched many threads on FTE looking for suggestions and many stated the flywheel cover(among other things) may be the culprit. Nope, all good. Turned out to be a heat shield on the exhaust crossover. It is welded on the four corners and one weld had let loose. It was almost imperceptible. It took going under on a cool morning with a small rubber mallet and giving it a tap to find it. Took the grinder out-no more rattle! If you have that elusive rattle give that shield a check.

This squeaking/squealing noise only happens when letting off the gas after accelerating 70%+ throttle. Quickly letting off the gas after revving up makes the noise . It sounds like it comes from under the drivers side door, and does NOT sound like a turbo. Its a creaky/squeaking noise.
Wont happen in park, does happen in 2wd or 4wd, on highway or in city. [URL] ....

Bought an 05 FX4 SuperCab in May - been in shop twice for a "clunking" sound when accelerating from a dead stop. Dealer says it's "operating as intended" and that no damage was being if I continue to drive. I thought it was a rear problem with the limited slip. Dealer says it's the tranny and that Ford is looking into the problem (apparently quite a few are coming back). She runs smooth and shifts fine once she gets going. Just starting from a complete stop feels painfully wrong.

While I am loving the fuel millage and ride of my new truck, I have my first concern. In the last few weeks i have hauled a truck bed full of dirt, and 3300 lbs of sod. both times i would use tow haul mode, and while the truck had plenty of power, it would shutter when accelerating from a stop. Mostly first gear 0-15 mph.
This is my truck with a fancy electronic controlled transmission, so on the old pickups this would be a torque converter slipping, but all the ford dealer wants to tell me is "its electrical and they want to reflash my transmission". I am at 26k miles and have less than 10k left on my warranty...

I got my b2500/ranger a couple of months ago and I've had very poor gas mileage. I replaced the air filter, changed the plugs, no luck. The truck has 169,000 miles. I haven't checked my exact gas mileage but from what i am seeing its horrible. I filled it up last night, not completely full but really close the full marker. In the morning i drove to school (7 miles) drove home, so 14 miles. Then i had to go back out by my school to pay back a friend. All in all about 28 miles. This cost me a little more than a quarter of a tank. The 2.5l has a 16 gallon fuel tank, so if my calculations are correct im getting about 8 miles to the gallon. I also took it the consideration that it was a half gallon from full.
And it wasn't just past below a quarter to full it was 3/4 of the way to a quarter from full. I know that i didn't test the mpgs "properly" but i think its close enough to draw a conclusion from. And keep in mind its not a 4.0, its a 2.5! Although i do think the engines size contributes to the mpgs because it takes ALOT to accelerate in this truck. At 2k rpm im barely accelerating from a stop light. And on the highway my engine stays a 2500 rpm doing 60-65. I am really hoping I can fix this because I don't want to drive around in a civic. Plus I need a truck for scrapping which is how I pay for gas as i am 17 and jobs are scarce. Also I know about cleaning the MAF butit has tamper proof torx on it which i do not have the tools to remove. I think it could also be the o2 sensors.

When accelerating and turning from a stop (like making a left hand turn), the rear end kind of stutters and then hops/bumps and goes smooth. One wheel turning faster than the other? Researching this site it sounds like the bad clutch packs TSB.
Question: How long can I drive with this problem before I mess something else up seriously on the truck?

Intermittent chirping noise when accelerating from a stop. It sounds like a brake chirp but it comes and goes. Not brakes. Changed pads and turned rotors chirp is still there.
