2002 5.4L... I have a humming noise that comes from my engine and wanted to see if any of yall knew anything about it. I sounds like it's on the other side on the driver side firewall near the brake booster. Once the engine runs for a bit it tends to start then. It'll start to hum then ill tap the gas to get the RPMs up a bit then its gone for couple miles then its right back on.
View 2 RepliesI've been noticing a low pitched humming noise coming from what sounds like the passenger side of the engine. it happened only occasionally at first but within a week of first hearing it, it is now almost all the time. here is some specifics...
-the noise always starts about 2 or 3 seconds after starting the engine.
-the pitch or loudness does not change with increased rpms or with truck in gear driving.
-the noise randomly stops for no given reason whether driving or idling then starts back up again.
-there are no performance issues while making noise, no dip in rpms, nothing. still runs the same
I've listened with the hood up and cant identify where the noise is coming from. is this something i need to get fixed asap or no? I've got a 2001 f250 5.4 with a manual tranny ....
I have a 2004 ford f250 5.4 and ithe makes a Humming noise only at idle. I have checked the fan clutch. it seems to be good and does not spin freely. I was thinking maybe idle air control valve but the truck idles like normal and does not stall. the sound does go away when squeezing the air hose doing today the IAC but comes back as soon as you let off. can it still be the idle air control valve if idles fine and doesn't stall?
View 5 RepliesI have a 2002 F-250 7.3. I was driving home from work on Tuesday (highway), I heard an intermittent noise coming from the front end, sounded like a rubbing/grinding noise. Yesterday on my way to wok, same thing, on and off. Yesterday on my way home the noise was constant, didn't go away. The noise comes at about 45mph and stays until I'm back under about 45mph, so mainly just on the highway. I put the truck in neutral and let off the pedal and the noise is still there which tells me it isn't engine related.
Yesterday after work I jacked up the front end, spun the tires, no noise. No play in the tires top/bottom or side/side. Took the tires off and what I did notice is the right axle u-joint is shot. I am hearing the noise in 2wd so I don't know if its the u-joint that's making the noise. Could it be a bad wheel hub bearing? Is it the u-joint? Maybe needle bearing??
Just noticed a ticking sound coming from my engine... just turned 160,000. Hoping nothing serious...

I have a rattling noise coming from the front suspension (both sides) when going over small bumps. Most people point to ball joints, but I find my case odd because I just replaced
Upper/Lower ball joints
Track bar
Tie rod ends
Shocks
Front U joints
Drag link
I did not touch the leaf springs or the sway bar, except to grease the links, which otherwise looked good.
I just bought a 11 f350 powerstroke. CC lariat 4x4 with 70k miles. Whenever i turn off the truck abt 30-45 seconds later a humming starts and continues for abt 1 minute. Sounds like a pump or a release of air? Is this a normal function or should i have it checked out. I've searched around but found very mixed answers.
View 4 RepliesI have an '06 F-250 that's making a quiet grinding/humming noise from what sounds like the front end. It doesn't seem to be coming from any side in particular, just an omnipresent noise whenever the truck is moving. It's constant with speed, and most noticable between 30-60 KPH.
Truck has about 268,000 KM on it right now, and has been worked pretty hard for whatever that's worth as well.
Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.
View 1 RepliesSo after this weekend's hurricane my 2011 f-250 started to making a noise when I accelerate. I don't know if water got in some where. But there's no MIL light coming on.
View 11 RepliesEvery time I apply brakes I hear a weird humming noise, as well as no stopping power. Checked fluids and pads and everything is where it should be. I heard abs can cause this but not sure on that. I know my master cylinder has a very small leak but it hasn't lost any fluids of that sort. I'm lost. I don't know where else to look.
View 2 RepliesI recently had a close encounter with some large rocks on a bad road and broke the power steering cooler. I lost some fluid and pressure as I had no brakes and it steered like a log truck. Replaced the damaged part and added fluid. I was informed by ford technician that air in the lines would make noise but would eventually work itself out. Well the brakes work and steering is getting better but it is noisy with steering and brakes. How long should it take to get the air out? PS the fluid looks foamy now. I should also mention it was making a slight humming noise before the incident with the rock.
View 9 RepliesI have a 2011 F-350 diesel crew cab dealer said I had a radiator leak so they replaced it now after I shut truck off it starts humming real loud like its relieving pressure my temps and everything else seems to be ok...
View 1 RepliesI have a 2002 F250 with 189,000 miles. Im having some very bad issues that im trying to fix. The truck idles rough, with fluctuating RPM's. In certain speed reanges it also shakes and runs rough. If I turn the overdrive off the shaking pretty much stops, but it still accelerates pretty slowly. There is also a whistling noise from the front of the truck until the engine warms up, someone told me it sounds like a bad intake manifold? Does that sound right? What could be going on with my truck? All spark plugs and coil packs have been replaced, as well as the fuel injector rails.
View 2 RepliesI've got a 02 SD v10 4x4 with Warn hubs and 97k. Bought it a couple months ago and I've noticed a vibration coming from the front driver side. Symptoms are that of a bad wheel bearing; vibration that increases with speed and not RPM, seems to lessen on left handed turns (weight transfers from driver side to passenger side) and gets worse on right turns. Also the truck seems very twitchy and hard to keep straight on the highway.
Snowed the other day so I locked in my warns (just in case) and I instantly noticed the noise and vibration almost went away entirely except for on the freeway around 70+ mph. Also noticed it seems less "Twitchy" on the freeway. Mind you the hubs are locked in but still in 2wd. After doing a little bit of reading some were saying this is a sign of bad needle bearings and not the entire hub.
I haven't jacked up the tire and checked typical movement in a bad wheel bearing. I know my way around vehicles and 4x4's pretty well...
Just picked up a 2002 F-250 Super Duty. I have a second 110V plug coming out of the grill. The first, on the drivers side, I know is for the block heater through the oil filter housing. The second is attached to a device that is inline of the lower coolant hose. Is this a warming device also?
View 2 RepliesI have a 2002 ford f350 triton 5.4 V8. I just put front brake pads on my truck today. Started driving around and i could smell burning brakes. Stopped and alot of smoke was coming from my brakes on my front passenger side but nothing from the front drivers side. Replaced all the brake pads on the front. What is making them so hot?
View 8 RepliesOn my 2007 f250 ext cab long bed when I got home tonight and parked it in the driveway I noticed a cracking or tapping noise coming from the right rear of the truck around the hub area. I bought the truck about a month ago from a ford dealer. The truck has 111k on it and runs pretty good. I have also noticed when I back the truck up a short distance and then put it drive and start to go forward that there is a slight popping noise coming from the rear end. I have had the carrier bearing checked and dealer says its good. What this might be. Could it be a sticky brake caliper?
View 6 RepliesI have a 2002 F350 with the triton 5.4. For the last week it has been running like crap. I just did my plugs about a month ago. I don't know if it's a miss fire or bad fuel or I don't know what it could be. It's a popping sound coming from my exhaust and when it happens I lose power. It happens off and on. One second it will run fine and normal and the next runs bad. What it could be. Today I just changed my fuel filter and added STP octane boost and fuel injector cleaner. Haven't seen a difference yet.
View 4 RepliesI had a buzzing noise on acceleration so today I cut all the heat shields off the exhaust system and also bent the bottom of the transmission inspection plate toward the front of the motor. It cured the buzzing noise but when I started the truck up there was a new rattle kind of sound, so I looked and found my y pipe is cracked where the passenger side pipe comes down off the manifold and connects to the pipe that goes to the cat converter.
I don't want to get a whole new y pipe could I order the spd Y pipe and that should work out right? it should be cheaper than a whole new y pipe aswell. I filled up the crack (it cracked 360) with weld but it was tissue paper so I would like to fix it before winter. I also still need to do my passenger side manifold studs and weld a new muffler because I found the rear half of mine is rotted off lol so I will probably do this all at one time.
I'm probably just going to pull everything manifolds and back off the truck, I have a feeling theres a bunch of rust sitting in front of the cat or muffler making the new rattling noise. Also in all my years of wrenching I have never figured out an easy way to get the exhaust off those rubber hangers, I always try to spray wd40 in there to get them to slide easy but always end up tearing them while trying to get them off.
I was having a ticking problem with the engine under load so I went ahead and did my manifold gaskets. I had a new 5.4 put in my 02 f350 last winter, and at that time I also installed gibson shorty headers. The tech had to plug the egr port with a pipe plug. But any ways, I pulled the headers last month and I used Percy's aluminum header gaskets. I also took the time to wire wheel all of the flanges and the mating surfaces. The one on the ball and socket flange was leaking on the passenger side, so I permanently sealed it with some 1800* epoxy.
The leak seemingly went away for a week or so, but it has returned. I sprayed down all of the mating surfaces with soapy water, but I can't find the leak. It only happens when accelerating or when i downshift to go uphill. So, at my wits end, I went to try and retorque my spark plugs. I've done half of them so far. Haven't driven it yet, but i was curious as to others thoughts on the subject. This leak cannot be heard at idle, nor at any RPM while in park or neutral. It is only apparent when driving. Definitely sounds like an exhaust leak to me.
