Ford F-150 - 1997-2003 :: Noise Like Belts Slipping Coming From Engine
Aug 29, 2013
I drive a 2002 F-150 (4.2L) with 150K miles. A noise similar to the belts slipping started up the other day but stopped when I drove the truck for a short distance. So I thought slipping belts was the problem but the noise started up again even after driving several miles. The noise only comes on intermittently and not all the time. In fact, it never comes on when a mechanic is looking at it so they think I am hearing things.
I had the belt changed out and the mechanic said he thought the water pump was going out. So I had that changed out. He had the alternator checked out and it was good. The truck runs fine but the noise still comes and goes. It sounds like a high pitch vibration or like something is rubbing against something else but only periodically. What it could be?

I own a 1999 F-150 V6 4.2 and would like solving what sounds to be a chirping noise coming from the engine. Noise is pretty consistent at which occurs at first startup while in park, drive or reverse and definitely every time I hit the gas from a standstill. The noise is pretty faint but bothers me just enough to where I want to ask the experts. Anyway noise began roughly days after I washed down the motor. I sprayed some degreaser on it and was very careful - making sure to cover the fuse box, alternator and high flow k&n intake air filter.
I stayed away from cables and just used a garden hose. Recently I had the lower idle pulley bearings replaced, serpentine belt and alternator. When I took to Ford for a new belt (it was old) and to inspect the chirping noise, they said # 6 spark plug was loose and that was the reason for the chirp (they called it a ticking noise). First of all how does a spark plug just come loose? They hand tightened it back and I drove the truck for less than a week then the noise was back. Any possibility this sounds like something specific that is wrong? My research says that it could be anything from the belt tensioner to the cam sychronizer to the heat shield around the cat converter.

I have a 2001 F150 4x4 4.6L Auto trans. 96,000 miles... I purchased it in Jan with 93,000. About a month ago it started making and occasional knocking noise coming from the engine, this noise was heard at idle in park and in drive. when I revved the motor it would go away but as the idle settle back down you could hear it again. the noise would go away as I was driving and come back with no rhyme or reason, I put a stethoscope on the engine and it seemed loudest under the oil pan. The oil gauge is up between 5/8 to 3/4. Fast forward to now, When I start it I hear a scraping almost grinding noise that resonated thru the cab it has the same intermittent characteristics. I think I am going to remove the serp belt, remove the trans inspection cover next and see what happens. Oh I did put a scan too on it, no codes but did notice 1 long term 02 sensor trim was staying around -.618 if I remember.

I have a 2004 Honda Element and when the AC compressor cycles on it makes a high pitched noise similar to a drive belt slipping. The AC is still cold and the noise is not overwhelming (yet). I know this vehicle has a serpentine belt and that doesn't appear to be making any noise. The only noise is when the compressor is running.
Is there a belt that drives the compressor (other than the serpentine)? And, is this something that I should get fixed ASAP or can it wait until my next oil change? Meaning, if I wait until the oil change (under 1,800 miles) will hurt anything?

The timing belts keep slipping on my car. I replaced the belts but it keeps happening. I went to readjust the belts today and noticed the pulley looks off. I know it needs to be replaced but given that it's the bott one under the radiator hose I'm not sure if it's one that I can easily do myself or if it would be better to have a mechanic do it.

So I'm doing some work on my friends car he just bought, 1990 gts, rebuilt 5sfe, not sure how thoroughly it was rebuilt, there seems to be a metal grinding noise coming from somewhere in the belts, sounds almost like water pump, belt tensioner, ac clutch, or something along those lines. I don't know much about these motors, anything commonly go out on these?

I've got a 2003 f150 supercrew with a 5.4 in it. I have a whine coming from the engine bay. I thought it was the power steering pump and changed that and that wasn't it. I'm thinking its the idler or tensioner pully. I've ruled out the alternator by wrapping rags around it and it didn't dampen the sound any.

I've got my sister's 1995 Dodge Neon with the 2.0L SOHC. While driving it recently I heard a horrible squeaking noise then a ZZZZZZzzzzzz sound. I immediately pulled over. The check engine light came on, and I shut the car off. Coolant was all over the place leading me to believe the water pump failed. I had it towed to my house, and now I will have it towed to the shop to get fixed. I would like to have them repair the timing belt and water pump. However, I am afraid that the valves were beaten to a pulp and now I will need a new engine. I was only going 35 mph when it happened. What are the odds that my valves were smashed up, and is there anything I can do to check them before I pay for a timing belt/water pump repair?

So I just installed a fresh 4.6 long-block in my '98 4x4 xlt and I have a noise coming from the manifold area. Thought it was possibly valves or timing chain. Took it to dealer and they diagnosed it as the Intake Manifold Runner Control. Never heard of it!!! Problem is, I can't find that part for this motor. Is it inside the intake? Do I have to replace the whole intake? Dealer didn't tell me, once I said I would do the work myself.

New to owing a ford pickup. I bought a 2002 Ford F-150 lariat 4x4 as a project truck. I've always wanted a truck to mess around with, but once I got the truck home I noticed it had a knocking sound. It didn't sound like it came from the top of the engine so I checked the muffler first and found it had a 3" slit in it. I replaced it but the sound remains. I heard it could be lifters? Is that something I should mess with or not?

I have a 1998 F-250 LD 4x4 with 462,000 km. I have been hearing for some time quite a drone coming from the rear axle. I am guessing the wheel bearings are due, as both front ones have been replaced, but never the rear. More about the noise, I hear it come to life as I gain speed. The faster, the louder. If I decelerate the noise is still present, but volume significantly decreases. Should I change the oil and friction modifier and see if there's an improvement or go ahead and change both bearings too?

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 was warming my truck up this morning and I turned my wipers on to get the bit of snow on my windshield off. The wipers moved a few inches, stopped, and a mechanical buzzing noise is coming from under the wipers. I can move the wipers with my hand and they'll go all the way up and return to the bottom, but do the exact same thing when they move again. I searched the forum but can't find anything about the wiper problem I'm having. I also see a lot of discussion about GEM in relation to wipers...

We are working on a 97 f250 light duty 4.6 4x4 5spd. Trying to figure out where a bearing noise is coming from in front end. Replaced both front hub bearings from napa. 150 each... the noise is still there. someone said could be cv shafts... although ive never heard a cv shaft make this noise i replaced them anyway cuz one was clickin last time was in the woods. bearing noise is still there..... in a long bank turn to the left the noise goes away till start to straighten out. while replacing the half shafts I grabbed the plates the shafts bolt to and spun them and checked for slack. none found. front diff's full with no leaks. as title says.... what next?

I have a '97 F150 4x4 with the 5.4L engine and automatic transmission. The tranny's been slipping on and off for a couple of years. It started when it was hot outside, I had been driving a long ways, and I was trompin' on the gas to pass someone. Still, the slips were rare. As it got worse during the hot summer months, I just minimized my long-distance travels.
I recently took it to a transmission mechanic. Like some of the feedback to posts in here, he felt it was a problem with the engine - because we had a bad EGR valve signal on the computer. (We still flushed the fluid. I later replaced the EGR and the DPFE. Another mechanic went through everything, replaced some valves that had something to do with the EGR, and feels the engine is 100% (and it runs very, very smooth). For those that will bring it up - I have replaced all of the coils (though it's been a few years). Having actually replaced some numerous times over the years, I can feel when one is bad (of course, the 'check engine' light as well). Lastly, we've replaced all bulbs in the dash so they are all working as well. Also, the transmission is not leaking. The computer system is giving us no errors/throwing codes.
After a couple of weeks, I happened to drive the truck a long distance one day and it started slipping. It got bad enough that it was slipping every time going from first to second gear. It would usually engage as I took my foot off the gas. Since then, because I haven't driven long distances, I have not had a problem.
The transmission mechanic thinks it's still an engine issue. He also mentioned a mechanical/electrical switch system on the side of the transmission (?). Give me a list of things to look at.

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...

I have a 1997 F150 4 x 4 with the 5.4 overdrive transmission. When I accelerate from a stop I can feel the slip of the transmission until I reach exactly 35 miles an hour. Above 35 seems to be normal and have plenty of torque.
The funny thing about this is I have had a 2001 Windstar same 35 miles an hour. I have also owned a 1997 Ford Explorer with this exact same issue. Three different motor and trans combination that will not lock up until you reach 35 miles an hour.
The truck has 213,000 I have replaced all coils fuel filters catalytic converter and torque converter. Have exterior tranny cooler. engine runs good and strong. And no code I have a reader.

Have a noise coming from the serpentine area. Sometimes it's a bit of a chirping, other times it's almost like a solid grind.
I pulled the belt off and the idler pulley had a bit of play so I replaced that. The tensioner pulley felt fine. I'm suspecting the fan clutch, as the noise only appears after the clutch has disengaged the fan (although it could be this is just masking the other noise because I've got a heavy duty / loud fan clutch setup).
How can I be sure that the fan clutch is the culprit before replacing it?

Got a 1999 ford f150 2 wheel drive. I have replaced both upper and lower control arms with ball joints on both sides. New shocks, new stablelizer links, new inner and outer tie rod ends. Also, a new steering gear and i still have popping noise coming from both sides around the wheel area when i enter or leave out of drive ways, turning, or running in a hole. Doesn't do in going straight. I don't know what else to do. Driving me insane. I keep spending money on this truck and still where i first started.

1997 4.6L.. Have an intermittent grinding / dragging noise coming from the pulley (?timing) area that I'm trying to pin down. Both the alternator and tensioner were replaced prior to the noise starting. The ac compressor and the power steering pump are original. The fan clutch was replaced about 4 years ago and the water pump 8 years ago. Timing chain / guides / tensioner are all original.
I don't notice any of the common ps pump indicators (whine increase when steering) but noticed the fluid level was down slightly and that the pulley seems to have some inward - outward play with the belt off. I also don't have any other engine symptoms like rough idle or any codes being triggered. How to isolate the culprit?
