Ford F-150 - 1997-2003 :: Rod Knocking Sound Coming From Bell Housing
I have a 2003 F-150 4.6 4X4. I had a knocking sound that sounded like a rod knocking but was coming from the bell housing. After some research, I found that it could be a cracked flex plate or bad torque converter. I bought and installed a new torque converter with no change. The flex plate didn't appear to have any damage but went ahead and replaced it with the same results. I actually started the engine by jumping the starter (with no transmission) and the sound was coming from the flex plate/dust cover. My question is do I need the dust cover? Or is it a bearing or something else inside the engine causing the flex plate to hit the dust cover?

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 97 7.3 ... I've had it about 2 months now and now it wont start! It will start and idle for 2 seconds then start knocking and die! I had a buzz test ran on it and all is good. I also checked my Icp and checked my uvch harness with my multimeter. Before this it would run ok but seemed like it had a miss and a lack of power. On start up if i didn't have it plugged in it would smoke white smoke horribly. I am thinking maybe my IDM. I need my truck for work .... I had it hooked up to a scanner and it said faulty IDM.

The last couple days my truck (1997 f150 4.6l) has been having starting issues. At first it would just turn over and not start then the battery would die. So i bought a new battery and yesterday now its starts sometimes but when trying to start it while its ttuning over it stops then starts turning and starts up. Then i drive wherever I am going when i get back in to start there's nothing.
Its not turning over at all but when i turn the key there is a loud single knocking noise coming from behind the dash near the passenger floor vent. Actually there ate two noise from the same area, one when i initially trun the key and another when i release the key. But after just sitting there doing this it will finally turn over and start. What this is, there are no codes being thrown besides my dreaded P0401 which i cant seem to get rid of either. Ive changed every part that has to do with the egr system and cleaned the throttle body replaced vacuum lines and still the code.
Ford F-150 - 1997-2003 :: 2000 5.4L - Intermittent Engine Knocking Underneath
The knocking started very suddenly 2 days ago - but not after any unusual events, other work etc. Truck has 145 K, and otherwise starts & runs perfectly. Doesn't use oil.
I heard it from in the cab, windows closed. At first, thought it may be a rod bearing - but if so, not terribly loud. Didn't drive it any more after getting home. But starting it in the drive, the knocking was audible.
Then I discovered it * completely disappeared * several times, after shutting off engine, then restart a few seconds later. When that happens, absolutely no knocking at idle or reeving it up a bit. But it may return on the next 1 or 2 restarts, then disappear again.
Since the knocking * completely stopped * on some restarts, does that rule out a bad rod or main bearing?
I haven't seen oil gauge pressure fluctuation, whether it's knocking or not. The gauge is where it's always been - well above 1/2 way. But, the gauge also doesn't move when I rev it to around 2000 RPM (? may be normal not to move, after engine's already running?). When the knocking is happening, increasing RPMs also increases the knocking frequency.
Can't hear the knocking from top side of engine w/ hood open - even using rubber hose to my ear & moving it around. But (when) it knocks, can easily hear it inside the cab or under the truck.
From underneath, knocking is more in the center of truck, near the back of block / oil pan or tranny bell housing. I can't isolate the noise as more on one side of the block than the other.
Could the oil pump itself be making a knocking noise? The knocking is "similar to" a rod knocking, but doesn't seem quite as "hammer on metal" metallic.
There are no DTCs showing on my scanner. Only odd thing was, for "O2 Monitor Test," it showed "vehicle did not return data for any O2 monitor test." Though under the scanner "I/M Monitors," it shows O2 Sens Mon. "OK," and O2 Sens Htr "OK."
Chevrolet - S-10 :: 1997 - Timing Is Off / Engine Sound As If Bearings Are Knocking
Looking for a diagram on 1997 S10, 2.2 timing settings? If timing is off, will the engine sound as if the bearings are knocking somewhat? I installed a new crankshaft and new bearings. Also do the ignition coils usually go bad? Should the #1 cylinder be on the compression stroke?

My 2004 Santy 3.5L (I am the original owner) just turned 91.4K miles and all of a sudden a VERY LOUD Engine Knocking sound came from the top of the engine. I have been changing my own oil since new with synthetic Mobil 1 and a new filter every time, and I never had any issues. I changed it last week at 90K prior a Spring Break trip (1350 miles).
Then yesterday after I let her rest for 1 day, I took the kids to school and within 10 miles of my house the ticking HARD loud noise started happening. I pulled over near a shop (within 1 block of where the noise started) and they said...don't drive it it sounds like a lifter collapsed, or a rod bearing or something big...
I had her towed to the dealer and the first thing they told me is to gather all the oil change receipts and a "manifesto" and they asked me how often I change the oil... I said every 5K miles. I change my own oil and have done since day 1.
BTW, Timing Belt, Water Pump, tensioners, belts, coolant, spark plugs and coils were changed last year at 77K miles.
The car should still be covered under the 10year/100K Powertrain and I believe they are trying to build a case so Hyundai can cover this or not...
They still need to tell me what's wrong... I change my own oil so I don't have receipts for "oil changes" and I have a log of when oil was changed...

I have just finished changing head gasket. I started up the engine works fine. But I hear a little clik sound form the converter. I put it in gear, but it can't move either forward or backward. It ran 2-3 liters of oil out of the converter when I took the engine out. I have filled new oil in the gearbox but not in the converter, dosnt it came form the gearbox into the converter?Is there air in the converter or what's wrong?
it is a F150 4x4 4.6 1997 automatic.

Ford F-150 - 1997-2003 :: Clicking Sound Coming From Steering Wheel
I have a 97 F150 that I just got a few weeks ago. I was driving home Wed. night when the 4x4 low range light would come on and off intermittently I had it in 2h the whole time. I went online and couldn't really find anything on it. So I get up to go to work on Thursday and the truck wouldn't even turn over. The battery was dead. I have put in a new one but now after turning the truck off I hear a clicking sound coming from the steering wheel. What this may be?

I have a 2003 Ford F150 with a 5.4V8 Triton 4X4. The truck is about to roll over 200K here soon. I am feeling/hearing a vibration/grinding sound coming from the truck when I am moving slowly and making turns, either left or right turns. Seems to happen more so on left hand turns. I have changed all power train fluids and filter, and still does it. I do not feel or notice the vibration/grinding when I am going straight or at highway speeds. It is only when I am moving from a stop and making turns. How to diagnose, find out, repair, fix this issue?

My '01 F-150 2WD, XLT has a foghorn sound coming from the left front side at idle after the 4.6L is warmed up. It goes away with an increase in engine RPM and is unnoticeable at hwy speeds. I have no codes (I have checked w/ my code reader). The service desk guy at the stealer said it is my abs pump going bad (I figured it was a pump of some sort, my 55 packard PS makes the same noise when almost empty-the system leaks). It also appears this is a stealer only part, and going to cost 6 or 7 benjamins to buy and probably another 5 benjamins too fix.

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 have a 2003 F150 manual 4WD with 4.6L engine and 165000 miles. When i am driving i feel a vibration in the steering wheel and on floor board that intensifies when i press the accelerator. I do hear an irregular humming that sounds like it is coming from the driver side front. I checked the wheel for any play but it was very tight. i check tie rod ends, ball joints no play. i recently changed both u-joints on the rear shaft and the bearing hub on the passenger side front. Also, the steering feels a little 'wobbly' when i make sharp turns. it almost feels like it is giving. What else should i check?

We've noticed an audible knocking that sounds to be coming from the front drivers side. It only happens at speed (over 30) and doesn't seem to be engine related. I can feel it under my resting foot while driving. I know this is vague but I think it may be enough to get started on figuring this out.
View 14 RepliesFord F-150 - 1997-2003 :: Noise Like Belts Slipping Coming From Engine
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?
Ford F-150 - 1997-2003 :: 1999 - Chirping Noise Coming From Engine
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.
