Ford F-150 - 1997-2003 :: Pronounced Bounce At 42 MPH / Annoying Vibration At 67 MPH
Aug 14, 2012
2001 F150 2WD 4.6 102,000 miles.... All rotors and pads replaced by a shop and the trouble began. The shop swore it was my tires and like a dummie I took it to Sams and had my tires replaced.
What's been done? New BFG Long Trail T/A Touring Tires, rotors and pads were replaced a second time, new Monroe shocks and the shocks were replaced a second time, new U-joints, front wheel bearings repacked, ball joints inspected and have slight wear, new driveshaft at 20,000 miles, two new rims, two new back tires of same type, wheels balanced over and over with road force equipment. All this got rid of a dangerous shake at 67 mph but did not affect the 42 mph bounce.
I now have a pronounced bounce at 42 mph. I have an annoying vibration at 67 mph that is present 97% of the time and an occasional smooth ride for 3-4 miles on the interstate before the vibration resumes. The ride is always rough until the tires warm up. I think the vibration is caused by the road and the truck can't stop it, but I'm not sure. Three shops are scratching their heads.

I recently bought a 2006 F250 Super Duty, 4X4, 6 liter diesel. My issue is that I have an annoying vibration/bounce between 45 and 50 mph. I thought it may have been a tire out of balance, but even after replacing all 4 tires and rear brake pads the vibration is still there.

I have a 2001 F-150 Supercab with the V-6. This past weekend it developed some strange noise best described as a rattle or vibration that sounds like it is coming from under the driver's side dash possibly somewhere right behind the instrument cluster. May even sounds a little like a "grinding" noise - like two plastic gears not agreeing with each other, but I don't know of anything under there that could make that noise. I have opened the hood and listened from there with my wife pressing the gas to make the noise start, but can't hear anything from outside the truck.
It is not constant, but starts as soon as I give it a little gas, even before I put it in drive. It's a little worse when it is in drive. I have turned the air on and off, turned the steering wheel, pressed the brake, etc, and it doesn't appear to be related to anything obvious. I have stuck my hand under the dash and can't find anything obviously loose.

I have never owned a full size truck and I don't know what is normal. I found a nice 2003 FX4 Lariat with 104,000 miles. The truck was a one owner truck and spent most of its life in Mission Texas, and a short part of the time in San Diego. At any rate during the test drive I was really liking it, but then I merged onto a highway made of concrete--it was like riding on a washboard road. The bouncing was so bad that there was no way I would buy that truck, felt like an old hard tail Harley. I thought it was just bad shocks, as they were kind of bad, and the ride a little float-like, but then I found a few posts on bed bounce.
The manager said he would put new shocks on it and check the wheel balance. I told him I would do a little research and get back to him. The truck is nice for its age, but I could not handle that bounce, especially since California has so many concrete freeways. Is there any solution? I have read a few posts, but mosts were old, and offered no resolution. 2003 F-150 FX4...

I have a 2007 F150 FX-2 which i bought new. I have about 60,000 miles on it, and every 8,000-10,000 miles i develop a pronounced vibration when i apply the brakes. When i first had this problem, at about 10,000 miles on the odometer, the dealership replaced the pads and turned the rotors, but the problem resurfaced before another 5,000 miles had passed. About 10,000 miles later the problem resurfaced, the dealership said they replaced the rotors.
The problem resurfaced again at about 37,000 miles, but the dealership claimed that since I was out of warranty. Being handy, I replaced the rotors myself, but now, about 15,000 miles later, I'm experiencing this issue again. Is this just a common problem i will have to live with? I don't tow anything, and i rarely load the bed with anything. Maybe a trip to the hardware store once a quarter and i load a motorcycle into the bed two or three times a year.

I purchased a used 2008 F150 with 62,000 miles. The truck is in excellent condition and is a crew cab with the short bed and the 4.6 v8 engine. I changed the 17 inch wheels to a set of Ford 18 inch wheels with Goodyear tires that came off another 2008 F150( XLT model). The tires had less than 15,000 miles on them. Since that time I have replaced 3 of the 4 tires because I could not get the tires to balance out properly. I have had all the tires and wheels balanced with the road pressure balance and the front and rear end have both been aligned.
I cannot get the RIGHT REAR of the truck to keep from bouncing and hopping at almost any speed. It changes from day to day a little bit but while slowing down I get the hop vibration( when I apply my brakes) and while at speed ( mostly 45-55) and above 65 I can constantly feel the truck vibrating. It is apparent it is the right rear. I took it back to the dealership where I bought it used , they could not find any issue. At some time, the rear cover to the rear end has been taken off but I cannot find any information through normal channels as to why.
I was by the shop that balanced the tires it is a Goodyear problem. All I know is that I cannot enjoy my ride due to this very apparent hop/bounce from the rear end. The alignment shop said they could not do anything more to make it better. Is there a FIX to this? Is it a problem with this model truck? The truck has 69,000 miles on it now.

We just bought a new 2013 F150 Platinum 4x2 with 5.5 bed. Love everything about it except that we have noticed it bounces and/or vibrates a lot on concrete roads/highways. Dealer admits this is an issue with truck, but won't admit any design flaw, and has suggested Bilstein shocks as well as putting 300+ lbs in the bed. We've heard from the Sales Rep, Svc Mgr and Svc Advisor that they've done similar things with their trucks to overcome this problem. Before we invest more $$$ into a fix, we are looking for any tried and true solutions from other like-truck owners.

My '97 Lesabre is giving me some what of an issue of battery vs alternator. I retired last year and the car isn't getting the use it had when I was working. I replaced the battery last December and have had to force myself to just run the car for the sake of running it, otherwise the new battery would go dead (even in weeks period) and I would have to charge it. Last year we changed insurance companies and to get a reduced rate, they required plug-ins to monitor your driving habits. I suspected that being added and the factory security system being armed might be enough to discharge a new battery.
I began by locking the car w/o arming security and all seemed to be working, along with driving the car more. We just returned home from a one week vacation, the buick resting in the driveway. When I went to start the car, I got the similar "I am dead" clicks and a very pronounced thump. I put the 10amp charger on for three hours and started the car. Engine runs rough, alternator gauge on dash is up and down at idle, can't get a clear screen on the OBD for codes. My question is, could this have been an alternator going bad all along, draining the battery when sitting idle/little use and now the roughness in the engine? I can easily replace the alternator....

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 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.

2001 7.3 4wd srw ext cab auto 173,000 miles. Truck rides rough at certain speed. Worse at 45 mph. I have replaced tranny mounts,new Michelin tires,replaced aftermarket rims with rims that are correct and balanced.Transmission was rebuilt,works very good, I have receipt. This truck had 2" extenders on the hubs when I bought it,have since removed these,that worked with bounce issues. When I replaced tires I thought I had cured the issue but now after 1000 miles it is back. I am ready to just ride it out until it becomes worse and identifies itself. Tires needed replacing,so did tranny mounts,it is frustrating bouncing along not knowing if it could be an easy fix or not.

Really annoying squeaks on one of the bushing areas. I understand these are known to go bad, and curious if there is any option other than lifting the truck off the frame? 2003 Moutaineer....

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?

My truck was running awesome, until, Out of NOWHERE, she started feeling super sluggish with a lot of loss of power, sounds like she is misfiring,or out of timing, and all the sudden started vibrating, the harder I accelerate, the more the vibrates.
When I start her up, she idles fine.If I try to drive her,givin he gas is like pulling a trailer with the e brake on, and she starts to vibrate. I've looked at some websites that have diagnostics from Bad timing, to spark plug wires, to plugs, to a bad fuel pump.
So I did what any other self diagnosing guy would do, I hooked up an actron scanner to see what codes she pulled up. Below are the specks of my truck, and the codes the actron scanner gave me. It just shows me codes, and have no way to interpret them..
BTW, I parked the truck till I find out what the hell I an do to fix her, not many mechanics where I live, so It looks like I'll be going at it alone.
So for the vibration, I checked the obvious, tires and rods are good and tight,had someone check the rotation, and its not alignment or balance.

Last August I bought a 2002 Ford F 150 extended cab 4x4 only until the weather got really cold did I start noticing this kind of like almost vibration or like the rear end is slipping but it doesn't happen all the time it only happens when I take off but once I get driving then it goes away...

Bought the truck knowing it needed a little work because it sounded like a diesel when running. So I had the timing chain, tensioners, water pump, etc. replaced and that fixed that problem. Then, a couple days later, a spark plug blew out of the engine. So, I go to do a full tune-up to find out that 3 of the 8 cylinders already had heli-coils in them.
I pulled those three and bored out and re-tapped the cylinders using the Cal-Van inserts. This has worked beautifully so far. I also replaced all of the other plugs as well with double platinum plugs. I also replaced all COPs. This got the truck running again and it drives great. No loss of power whatsoever. It just runs like a dog at idle. As soon as I give it throttle it smooths out completely.
It seems like the problem gets worse as the engine starts to get up to normal operating temp. Basically, if I am idling, in gear or in park, the truck shakes pretty bad. It kind of feels like it's starved for fuel or barely missing. I do not have any codes though and if it is a miss, it is completely gone under throttle.
Other things I have replaced within the past couple of weeks:
EGR
EGR vacuum solenoid
DPFE
Both PCV elbows
PCV valve
Air filter
Harmonic balancer
Other things I have done:
Cleaned IAC
Cleaned throttle body butterfly (including EGR ports)
Checked TPS voltage
I'm sure there are other things that I am forgetting.
The idle seems low to me but I'm not sure what is considered standard for the 5.4l. Mine idles around 600 in park once engine is warm and the needle doesn't move despite the roughness felt. Just going by the tach, you would think that the idle was smooth as silk.

I have a 4.6 01 F150 with 3.08 rear end I got back in Sept. In Nov. I replaced the timing chain/guides and brakes/rotors all the way around. I have also flushed the cooling sys. and replaced all the coil packs/plugs in Nov. About 2 months ago I started feeling a vibration(feels like the truck is bouncing most of the time not bad but I know something isnt right) at ~37MPH. Not always bad but 98% of the time you can feel it.
I feel it at other speeds sometimes also. 2% of the time I dont feel anything. It had older tires and I got a new set ~ 3 weeks ago and its the same. A couple days ago I put a GoPro under it and filmed the driveshaft and it does seem to be bent some. What might be my issue or things I can check myself? One other note is the previous owner did use the truck to haul a horse trailer some and I know now that rear end was not the best for that! Truck has 210K on it and engine was replaced at ~ 150K

01' Screw 5.4 4wd. Went camping this past weekend and it was the first outing for this truck our TT weighs 6k. When accelerating from a dead stop going straight I'm getting a rumble strip like vibration that last a second. If I take off very easy it doesn't do it. I've seen similar post but no definitive solutions. This truck has less then a 100k on it and so far I've changed the trans filter/fluid rear end oil with modifier and new spark plugs.
Once I'm rolling and hammer down it won't do it. It's more of a annoyance then anything.
