Ford F-150 - 1997-2003 :: Clunk When Accelerating And At Takeoff
Mar 29, 2014
So I have an issue with my 03 f150, Basically It clunks in various scenarios such as Accelerating also occurs take off and general breaking/slowing down but not really when stopping. December when it was cold and I was decelerating (not on the break just coasting) it feels like i was driving on the shoulder.
It does it much more in cold weather. Just had the truck out getting a little rough with it for 5 or so hours today and 0 issues with it.
I was thinking it was a slip yoke issue that I hear allot of trucks have the issue but I was at the dealership today and both guys and a mechanic sitting there were like "never had that issue on an 03 f150, might be your back end." They also stated the clunking would always occur and be more prominent when breaking which its not.
I am certain its not the transmission its not occurring with any shift point. Kind of hard to do it if its hard to reproduce in the heat.

i have a 1997 150 4.6l with 166xxx miles. when ever you go to take off there will be no power and then all off the sudden it will shoot up too 4000rpm and then you back off it will be fine. Until you stop and go again. Also when ever you come up to a stop it drops down to 500rpm. What might be going on?

I have a 2001 5.4 4x4 supercrew with 300,000 miles.. This truck is my baby. Recently when I start it up and after putting it in gear and begin taking off my engine is loud as if I am revving the engine without any indication in the rpms. I want to say it starts out on the trip a tad sluggish. Is there anything I can do to eliminate?

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...

My husband bought a 1997 Ford F150 and the seller said he changed the brake lines, but the back brakes have dragged on takeoff since he bought it. Just put new shoes on it and it's still doing the same thing, but now the drums are getting hot. Is it possible that the seller got the brake line backwards and that might make the back brakes drag?

So for the past few months I have been hearing a knock sound when taking off from a stop. It does it every time, and its loud enough to hear distinctly. It sounds like it is coming from underneath the cab, maybe the trans or rear engine area. I thought maybe a mount. It only does it when taking off from a stop it does not do it while driving. Where to start. I hope it isn't serious, at this point it is more annoying than anything else.

I have a M5OD that I replaced the clutch in in my '99 150 4wd in December . Manual Tranny. Now when taking off in 1st gear the transmission seems to be sliding or shifting backwards, but only in first gear. Got under my truck and looked, can't find any identifying marks to where it might be moving or what is causing this. All frame mounts are tight and the bell housing is flush with the motor. Yes, i did do the clutch change myself in shop class.

I've got a 2003 F150 4x4 supercrew that's got a 9.75" rear end with 3.73 gears. I just replaced clutch packs and spider gear set 2 weeks ago. The last day or two I have noticed that when I make sharp turns that it get a whining like spinning noise. It sounds to me like the spider gears are spinning. It only does it when making sharp turns. There is no noise going down the highway or normal driver. I have noticed at times I get a little shutter when I go to take off or back up. Kinda feels like a brake is hanging. I put friction modifier in when I did the clutch packs and everything. Maybe not enough?

I have a 98 expedition with the 4.6l 4x4 and it has 158,000 on the dash had a new engine installed at 100,000 it started running rough and sluggish last week so I changed out the spark plugs and while changing the plug I notice oil on the threads of the two rear passenger side plugs. After the new plugs it was smoking pretty bad blueish white smoke. I figured it was the oil from around the threads that had leaked into the cyl.
The smoked cleared after 2 days and ran great for a week. Now its doing the same thing again real rough idle and and its extremely sluggish. I can put the pedal to the floor and she barely wants to move almost like the tranny is going out but the rough idle leads me to believe its and engine problem. I have the check engine light on but can't get any codes. I also tried checking for vacuum leaks by spraying either round the intake and vacuum lines and didn't notice any change in rpms so I'm guess the vacuum is fine.

I had heard clunking when hard accelerating or hard stopping my 2003 Explorer, also heard it from Park to Reverse/Drive. I suspected u-joints, was correct, those were replaced.
After I received my car back I noticed the clunk was louder when hard accelerating or hard stopping; again from Park to Reverse/Drive. I suspected rear differential. I called my mechanic who said they noticed some play in the rear end - a little loose, that the noise would be noticeable...but that if it were him he wouldn't worry about it. He said the drive shaft was tight, that I wasn't in danger of it falling out, etc.
These are the only symptoms I have that something is wrong with the SUV. Just that clunk. If I come off slow from a stop and not hit the gas, there is no clunk. If I do not hard stop, again I can avoid the clunk. The vehicle does not vibrate or make noise on the freeway, shifts well between gears.
I was going to have my mechanic open the rear end up and see what needed to be replaced when the cold weather brakes. In the meantime, is there anything I need to be keeping an eye on, or something else I should check? My mechanic said the checked it over and couldn't find any other problems. I just want to be prepared for expenses.
It's a 2W, not 4WD. I had all the fluids done, a drain and refill on rear. Not sure if that's important to know or not.

There is a TSB on it,10-22-6 NOV 10 Drivetrain - Driveshaft Slip/Bump On Accel. Or Braking... Will they do any thing for me,and how much would it cost me to have the work done at a shop.

2010 F150 XLT FX4 5.4L Crew Cab Medium box, nice blue truck, lacking on chrome though.
My friend has a clunk/lag on take off from a dead stop only. Drives fine down the road, but when taking off from a complete stop, you step on the gas, and nothing happens for a second, feels like it lags, then clunks, gives a jerk, and takes off.
From talking to other newer Ford owners, seems like a common problem.

I've been having this problem for about 2 weeks now, and I am trying to figure it out. I know the video is only 5 seconds but at least you can hear the sound, it only happens in first gear, on take off, about 2-5 seconds after the take off, and the sound is coming from the rear axle area. I cant figure out if its diff or brake related.

As I said when I take off from a dead stop I can feel a clunk or a bump that feels like it is coming from the rear wheels. I can feel it more than I can hear it, although I can hear it a little. It is difficult to describe this. It is only for a second and kinda feels like the rear wheels have no traction then it bumps and takes off. If I ease into the accelerator I can avoid it, but I don't have to hit it real hard at all to get it to do it. I am sure it is not u-joints as I put a brand new drive shaft from driveshaft specialist on in the spring.

Well it's been 300 miles since Ford applied their "special grease" and put on clamps to eliminate the clunk when slowing and the slipping feeling at take off. Now the clunk is back. Every time at 25 it downshifts and clunks, then once again at 10. Drives me nuts. My service advisor wants me to "log" these visits so we can be more aggressive with Ford to get this resolved. I love the truck, but this is annoying driveline slop. Almost like the splines weren't cut right and Ford is using heavy grease to fill the gaps......developing...

I'm new to the VW family as a couple weeks ago I purchased a 2003 VR6 Jetta. So far I LOVE it and it's been by far my favorite car I've driven. About a week ago, I was visiting my parents back home (I'm a college student) and when I went to turn on my car to go back to school I received the alternator workshop message. I didn't want to take the risk so I took my sister's car back to school and my dad took my car into a local mechanic during the week.
Unfortunately, the mechanic we took the car too does not specialize in European cars (They're just a general mechanic/Ford dealership), but we didn't want to take the risk of driving a car with a potentially failing alternator to the closest VW mechanic (About 40 minutes away). The car was repaired and a new alternator added. All was going well, but I began to notice a slight "clunking" noise when first accelerating/lifting my foot off the brakes. I didn't think too much of it and it wasn't very loud nor severe. To me, it sounded like the interior plastic shifting when I moved.
Anyway, here I am a week later and I'm noticing a lot of noises that didn't exist before, including the clunk I just mentioned. I took a few audio recordings. (For the record, there is NO CEL or any dash lights currently on, thus why I'm not as concerned).
The first audio: [URL] ....
In this link, I'm driving the car around the parking lot in which I park my car here at school. It's mostly bumping gravel, but at the time of the recording I was driving very slow. You can hear a squeaking noise.
The second audio: [URL] ....
In this link, I'm revving the car while parked. Something I've noticed that it didn't used to do is rattle while idling ever so slightly (It's not audible in the recording), but in the recording you are able to hear a slight clunking noise.

All right, I went ahead and rebuilt my suspension considering everything was worn out. I used upper and lower control arms and all the tie rod ends from O'Reilly's (MasterPro). While I was under there I noticed that the sway bar end links and bushings were deformed and worn, so I changed those out.
The clunky front end is confusing as hell to me. All of the front end bushings and ball joints are new, and if I hit bumps with a little vigor it rattles. Under hard braking to a stop there is a loud clunk from the front left. I have shocks on the way (Monroe Reflexes for the front, Sensatrac load adjusters for the rear), which are the only things left that have been removed and not replaced with new ones.
The truck was perfectly clunk and rattle free with the old worn out bushings and ball joints. I can't imagine why it would start clunking now with a new front end. I felt the new ball joints and they were tight and didn't have any play. The bushings were tight. I'm at the end of my rope with this crap. I've double checked that the ball joint and chassis nuts and bolts are all very tight.
