I have a 2004 F 150 ford lariat triton 5.4 it makes a distinct diesel engine sound in low RPM should I be concerned, is there anything I cnd do. Is it a concern, does it make a difference in the gas mileage.
View 2 RepliesJust had the 10k service done at the dealer. Oil change and inspection and now there is a ticking sound from the engine. It was not there when I took it in, even my wife noticed it. Will take it back to the dealer on Monday, but wanted to hear the groups thoughts. 6 cyl non-EcoBoost engine
View 10 RepliesIt only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.
After engine is up to temperature the engine has a buzzing/whining sound just at idle. Pick up rpms and its gone. They thought it was comeing from the oil filter and changed the filter and it disappeared for a while but its back again.
Very hard to pinpoint the sound even with a styphiscope. Going back to dealer.
2012 6.7 F250 with 17k miles. It's getting hotter here and the last couple of days when shutting down there is a sound coming from the engine compartment that sounds like an air pump on one of those load-leveling systems. It will go on for about 15 seconds then stop.
View 12 RepliesI have 140,000 miles on my 2005 F-150 and for the past year I have noticed a somewhat high-pitch whistle or howling sound coming from either the front or underneath. The pitch and volume continuously varies as though it is just tire howl, but I just changed all four tires and no results. It gets much louder at about 65 mph and 78 mph, but I don't hardly hear it at any other speed. My brother says it's just a wind whistle, but I strongly disagree as it doesn't change when i drive against or with a strong wind. I rely on this pickup for work and can't afford to be without it for more than a day or two, so, for peace of mind at least, I would like to know what is making the sound.
View 6 RepliesVehicle: 1998 F150, 158k mi. MT (M5OD), 4.9l I-6.
Description of problem: About 2 weeks/500 miles ago, truck developed a scraping/squeaking sound. I thought maybe something was rubbing on the driveshaft, but inspection revealed no likely candidate, nor disturbed metal on the shaft.
Over the course of the next 500 miles, it's gotten worse, so that current symptoms exhibit themselves (to one degree or another) 80% of the time. The symptoms are:
- Worst on first drive of day, on first mile.
- Sound produced somewhere between scrape and squeak.
- Vibration noticed throughout cab and through steering wheel ONLY when foot off clutch...smooth as soon as clutch depressed.
- Giving it a little gas (at constant speed) usually smooths out symptoms somewhat.
- Recently had bed loaded to gross. Vibrations went away, to return once bed empty.
- MT fluid found to be full, in good condition, and with 15k mi since change.
So, what's up? Given that a load in the bed improves things, I was thinking U-joints: but the driveshaft spins in neutral, too, so why would pressing the clutch change anything? I also thought about tired clutch bearings, but everything I've read says pressing the clutch makes things worse, not better.
Is it worth examining the tranny-to-engine bolts?
I changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.
View 3 RepliesThe EMS service in the county next to ours lost one of it's new trucks for a few days on Tuesday. While going on a call, the engine made a tapping sound for only a few seconds, then a loud pop and shut off. Ford dealer went and picked it up and took it in for evaluation. VERDICT: Broken rod and cracked block. I have to say, this is the first I've heard of a 6.7L having a problem like this in our area.
Ford was really interested in this engine, as a new one is already on the way and the old one is to be shipped back for complete breakdown. So far, the Director and County Manager have been impressed with Ford's response to this problem. Dealer has told them the truck should be ready by the middle to end of next week. If I hear anything else, I will let you know. Any engine can break at any time, I'm just glad they are moving quickly to rectify the situation.
I've been noticing some weird, very subtle engine sound changes while driving at highway speeds lately. Something almost like surging, but not. I don't know how to describe it. I might try to make an audio recording next time I take it out so I can explain it.
Anyway, I don't know why but ICP popped into my head. Maybe, for some reason, the engine was varying ICP causing the surging sounds.
So I hooked up AE and did a test. I've attached a screen shot.
With my idle speed actuated as high as it will go, and ICP actuated as high as it can go, I can only get a pressure of about 1450 PSI. I always thought ICP should go higher than that. I seem to recall reading somewhere around 3600 PSI.
So am I misinformed, am I reading the data wrong or do I have a problem? How high should Injector Control Pressure go? I missed it in the screen shot, but ICP is actuated to 100%.
I have a 2014 Superduty with 41000 km on it. I was driving in a remote area yesterday about 53 km from pavement. I stopped for a break and had a very noticeable knocking sound that was more noticeable on the drivers side towards the back of the engine. I had no choice but to keep driving it. the truck ran perfectly fine for the 4 hour trip home(1 hour on gravel and 3 hours on highway) when I stopped a couple of times after that there was definitely no knocking sound an it is not there today, what this could have been? like I said the knocking was so noticeable that you couldn't miss it...
View 11 RepliesI am lost on what I need to do with my 2005 6.0. Last summer it started giving me trouble once in a while starting. I turn the key on and wait for the wait to start light to go out. When it goes out, turn the key and it starts, most of the time. Last summer I went to start it the same way, only it cranked and did not start. I turned the key off, back on and cycled the wait to start light again and turned to the start position, it started right up. Whenever it would act up I just turn the key off then back on and it starts right up. Usually on the second try, but lately it has taken 3 or more tries. I am not finding any real pattern to when it wont start.
When it does not start I can crank on the starter until the battery dies and it wont even think about starting. Turn the key off and back on, it will start.
Another thing I have noticed, when I crank the engine I can hear a clicking from under the hood right before it starts. I think it must have something to do with the injectors. I will crank the engine a few seconds, hear the clicking then it starts. If I don't hear the clicking it will not start, so when it doesn't want to start I also do not hear the clicking sound.
The other day I started it, drove 5 or 6 blocks and shut it off. After 20 minutes or so went to leave. I had to cycle the key 4 or 5 times off and back on before it decided to start. It is getting worse, doing it more frequently, and taking several times of key off and back on to get it going. Where should I start looking to find this problem?
I have been fixing up my 77 F150 since I got it in January and it's really starting to look nice! I love this truck, but I have noticed a clunk sound when I put it in reverse and also a same if not similar sound when I'm driving and slow down. It makes a clunk sound when it shifts to a lower gear, (automatic). Now, I was thinking it was a U joint at some point and crawled under there and started to grab them and see if there was any play in any of the spots but found no play. I checked it a few times, thinking well it could be just the point the U joint stopped and that would explain no play but after a few times of crawling under I still never found any.
View 8 RepliesMy husband's 04 F150 has an occasional ticking/clicking sound that comes from the right rear tire. It occurs in both drive and reverse, while braking or while driving and will stop with braking. We cannot establish a pattern. Brakes are good, we just checked them and they do not need to be replaced. We took it in to be evaluated, of course it did not make the clicking while they had it and they did not see anything to indicate an issue.
View 3 RepliesI have a 2004 F150 4x4 Fx4 supercrew with 5.4 engine and 46,000 miles. For the past three weeks now I have a periodic Grinding /scraping sound that seems to be coming from the front passenger's side of the truck. It can come on with light driving and braking in town or start while driving 70 mph down the interstate without even touching my brakes. The thing is I just about always have to come to a complete stop to make it go away. 10 Minutes later it comes again. It's loud enough for everyone around me to start staring at my truck. Sounds like metal scraping concrete and gets deeper as I slow down and when I fully press my brake pedal it goes "curchunk and the sound is gone for a while. I thought maybe my caliper was sticking or maybe the truck is trying to go into 4x4. One friend even suggested me to check the dust cover behind the brake for rocks.
View 12 RepliesI have 2003 F150 SuperCrew 5.4L XLT. For past month or so, have been hearing metal rubbing sound and had shakes in braking - as well as a "grabbing and pulling" sound near brake pedal - very aggravating to say the least. Weird thing is the grabbing and pulling sound only happens under 10 miles an hour or coming to a complete stop. (The grabbing sort of sounds like the sound the ABS makes when hit really hard)
Yesterday I had brakes and rotors replaced - mechanic said front rotors were beyond turning - very bad. 135,000 miles on truck. Felt more comfortable until I pulled out of shop and when I applied brakes, had the same grabbing/grinding sound, but no pulling. Went back to mechanic and had him ride with me to hear sound, and he is stumped.
Knew it was safe(r) to drive since new pads/rotors installed, but when I got up to 55mph and barely touched the brakes, the steering wheel began to shake violently - but no sound/grabbing from brake pedal area like I get when I am 10mph or under. Really at a loss right now.. What's going on?
Truck is a 2WD, also hear some thump thump thump sounds from front left tire, which are only one year old, but tire man said that was from suspension arm or something - nothing to worry about he says.
Some people have said "bearing" or "hub" but when brakes were replaced, the bearings were repacked...is this the same thing? Is the current problem safe to drive with? I do not take vehicle out of the county - just to work and back and hunting on weekends.
My work truck that I drive, a 2006 F-150 Lariat 4x4 extended cab, rear parking sensors quit working. The button on the dash is lit up all the time like when you shut it off. I posted this on the F-150 section too and was able to find a suggestion that you can listen to each sensor while in reverse and if you don't hear a clicking at the sensor it has failed. All (4) sensors are clicking away while in reverse so not sure what else to check, no one in the F150 section, so that is why I put it here.
View 3 RepliesRecently my brother in laws truck started making a buzzing sound while running and a much louder sound after it shuts off. Trying to track down the sound. Listen to the whole video because the end is where it gets loud.
6.7 powerstroke strange noise - YouTube
2006 for f150 with 107k miles...suddenly started shuddering whenever I give it anymore than a feather of gas, and it's under 200 rpm...after 2000 if seems to break out of the shutter and run fine. Exact same thing happenes to my 89 accura with 230k
View 7 RepliesI have a 2000 f150, 4.6l v8. I have two symptoms that I think are related but I am not sure. The truck has 92000 miles on it. No trouble codes.
1st. I get a vibration at about 67 mph that seems to pulsate.
2nd. I get a similar vibration at about 1200 rpm in park. This one seems to be much worse when i lift my foot from the accelerator.
I have had-the truck about a month, and just had the tires rotated and balanced.
So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
