Ford F-150 - 1997-2003 :: Clunk Noise Becoming Regular
Oct 7, 2012
I have a 97' f250, 4.6L auto transmission, 4x4, 168000.
I have only owned the truck about 5 months so I dont know much about the history. When I coast to a stop, (usually 40mph or faster) to a stop I get a clunk on the down shift into second I believe. It only happens when coasting to a stop, all other shifting up and down patterns are good. This happens I would say 7 out of 10 times but seems to be increasing.
The other issues that I believe is related happens every time I put the truck into reverse, there is a similar clunk. This happens every time and does not do it into drive.
I have ran lots of searches related to this in FTE, I cant get a clear direction to begin down. It seems like it could be transmission related but also may be driveline or U-joint related.
Two other notes-I did drain and replace the transmission fluid and I noticed that the T-case and transmission are much cleaner than any other undercarriage part. Whatever that means??

I have a 1998 F150 with a 4.6 engine and is a 4x4 now the other day when I was backing out of the garage I heard a clunk noise and it seems like it is coming from the right front, so I tried it going forward it made the same noise but not as bad. There is no road noise and all the u joints are good and tight, the noise was when I gave it a little gas. My question is the front cv u joint would this make the noise? And what about the hub? What is the proper why to check the CV joint and the hub? The noise was when I was in 2 wheel drive.

I ran out of CNG - truck won't start on reg fuel. Fuse good, relay clicking and I believe I have voltage going to plug connector going to tank. However, I do not have any wiring diagram to know what I'm looking for. The plug is four wire - yellow- 11 volts, red / black stripe 7 volts, black / red stripe and black wire no volts. What checks can I make before dropping the fuel tank and pulling fuel pump? 2003 F150 7700 Bi-fuel ....

Lariat stepside, 5.4L with 150k miles. Loud popping noise, almost a clunk, when making a slow sharp turn. Put it on jackstands and did the normal tire grab and shake and found no issues there. Tie rods, ball joints and sway bar links all seem tight. Looked for signs of unusual rubber to metal and metal to metal wear and found nothing. The only thing I did see was the rubber boots on the upper control arm ball joints were split. What I have checked or if I am missing something?

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.

I'm getting a CLUNK when coming to a stop with my truck.
If I shut off the overdrive while coming to a stop it doesn't do it. Or if I manually shift it down a gear.
I read on here it could be a U-joint or the yoke or something and maybe something needs greased.
Anyway I crawled under the truck and it looks like I need a special socket to remove the 4 bolts holding the driveshaft to the rear end.
What type of socket it this? No grease fittings on my U-joints. What's causing this CLUNK as well?

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've spent several hours over the course of the last week trying to figure out the problem I am having with my 1999 F150. When coming to a stop, there is a heard and felt "clunk" coming from the rear end of my truck. The other day, I had to brake to a stop rapidly and it felt like something had dropped out of the back end of my truck. It's 4WD with a 5.4L V8 with 240k miles. I have a fair amount of knowledge of the truck, having performed all maintenance and most repair, so if I need to check something and report back I should be able to. Also, I've owned the truck since it was new, and this is a recent development.

I have a 2000 Ford F150 XLT 4X2 that has a "clunking/squeaking" noise in the steering wheel, intermittent happens driving straight down the road, hitting bumps, breaking. It is very annoying! changed out lower ball joints tightened wheel bearings, greased idler/pitman arm thinking that was the problem and it became worse. Had someone look at it and stated that the steering shaft was welded?!?! Why would the steering shaft be welded what am I looking at in replacing it (cost for parts and labor time) and are there any other additional parts that will have to be replaced as well?

My 2002 F-150 with the 5.4 has an issue with a high rev (1000 RPM for a few seconds) while at a stop sign, along with a clunking/banging sound coming from under the truck. This is when I have the brake mashed all the way, and this all happens at the same time, almost every time I come to a stop at a stop sign or light. I do have an intake manifold leak, which i have recently determined, but I do not know if the high rev at a stop sign has to do with the manifold leak or to do with the transmission sounding thump I hear. Could this be a torque converter not unlocking, and then suddenly unlocking? Because after the thump sound, the RPM's go down to around 650 from 1000 every time.

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.

High beams work, daytime running lights work, fog lights work ........ regular headlights do not work. All fuses are ok.

This noise appeared for an hour, haunted us with regular appearances, then disappeared as soon as I drove the car to my trusted mechanic. I never heard the sound over the 6 years we've owned the vehicle and it hasn't come back. This sound was regular and repeated while driving, breaking, stopped in gear and even parked and idling. No vibrations or abnormal operation of the vehicle. Sounded like it was coming from somewhere right in front of the driver. Mechanic was stumped-something in the ABS system. Noise coming from under hood right in front of driver-2.wav.

So ever since I bought my f150 about three months ago it makes a whining noise from the transmission while I am reversing it. What could be the cause of this? Should I bring it in for a trans flush and filter change? What would that run me?

I have a darn gurgling noise behind the dash! Now I have read different things on this, it has been doing this for awhile, like as in about 4 months or more. Any way I've read head gasket, air in the system and heater core! Now I did have a t-stat problem. But I fixed that, it was about a week ago. But the noise was there before that! It doesn't overheat and the heat works good! Also I see no water in the oil or anything. By the way it is a 97 F150 4.6 extended cab. It runs fine it's just when I step on the gas it does this. It has me baffled right now....

At the above speeds my truck has a rattle/ticking. I think its the cats but I'm not sure. I checked all the obvious like the heat shields and stuff. The truck has 118000 miles on it and has been in So. Cal. its whole life.

I am having an oil pressure issue on a 2000 F-150, 4.6L.
I recently put a new set of heads on the motor because of some valve damage. Anyways. The oil pressure gauge in dash would sit at around 3/4.. Drive it a couple miles and every time you would get back to idle (stop sign) it would drop to zero and the light would come on.
You could also hear it make a little noise like the top end wasn't getting oil. (Didn't run at idle long..) I figured it was obviously starved of oil so I put a new oil pump, timing chains/guides/tensioners on. (Which I probably should have done with the heads.) Same issue resulted, but no funny noises when the gauge drops off.
Suspecting that the sensor may be faulty and the dash gauge being useless anyways, I dug an old mechanical gauge out of a box and installed it. I'm getting similar oil results. (Under 25psi it seems.) I'm not sure if the gauge has just gone to crap over the years of being in a box. However, the previous low-oil pressure issue seems to confirm it's not the gauge.
I cleaned the oil pickup when I had the motor apart. It didn't seem dirty, but I sprayed it out regardless. The motor looked fairly fresh when I had it apart. Bearings looked solid, cylinder walls even looked freshly honed. From what I hear, the motor was a low-mileage replacement.
So what could cause a low-oil pressure issue? Bearings seem fine, oil pump is brand new.
