Ford Excursion :: Rattle At 55 MPH - Loud Knocking
Nov 13, 2016
At 55 I get this rattle that sounds like something loose vibrating off something else, like the downpipe or something, and it sounds to me from the driver seat like it's coming from the passenger side firewall. The passengers sometimes say it sounds like it's coming from the wheel well but I haven't heard it yet from the passenger side. It's loud. Almost like a knocking. Really only happens at 55. I can't find anything lose. At my wits end.

Trying to find any information on what's happening with my 2008 2.2 Diesel Santa Fe ... Been driving fine until I pulled up at a set of traffic lights yesterday and started hearing a loud rattle- knocking coming from the engine at idle.
Put it in gear and drove and it goes away. When at idle if you rev the car it goes away.
Mechanic seems to think it could be clutch as it vibrates the gearbox, but sound seems to be more prominent around the engine, my thoughts were maybe a loose timing tensioner.
Clutch replacement is very expensive.

I have a 08 F-150 4x4 King ranch with 5.4L Duel fuel motor. Last year we were backing a trailer and the whole truck started shaking. Stopped, but it in forward and no problems, tried backing again and same thing. It did back up but shook worse with more gas.
We took it to a mechanic who said without even looking at it "Sounds like a reverse clutch, common problem" So we had them rebuild the trans, a few months later it did it again once but we were 300 miles from home. Since we could still back we did what we needed to do and drove home with no problems. Dropped it back at the mechanic who said he couldn't find anything and eventually had a yelling fight with my wife. We couldn't get it to happen again either until last week it did it again and she grabbed the camera to record it.
Took the truck back with the video, he had a mechanic look at it and said the transfer case mount bolts were loose, tightened them up which did get rid of a knock that we had since the trans rebuild and said that was the problem, it was binding and causing the shaking. This weekend did the same thing again.
Now the truck is back at the shop and only 100 miles or so left on the warranty (12m/12k). So after that long story my question is if the problem really was/is the reverse clutch or if there is something else wrong that he never fixed and was just intermittent enough that we let him get away with it this long?

I recently started having a very loud knocking noise in my engine and I can't place it. Mostly due to my lack of car knowledge I can only trouble shoot so far. The following conditions are what I can really only go from:.
- when I'm in park or neutral the knocking happens in about 5 beats per second.
- while idling in gear it almost goes away.
- while driving it increases in frequency and intensity the higher the rpms, until it switches gears, then its dull until I get closer to topping out another gear.
- No real functionality of the car has changed.
- I tried doing a mild brake torque, in both drive and reverse, and the engine did not move.
- the knock is pretty hard to locate exactly but seems to come from the passenger side.
I'm hoping it's not to serious because I just filled the gas tank.

So my fiance and I just purchased a 1999 Ford Escort SE (4 door). Drove it home, seemed fine. Was told it just needed some TLC and would be good to go. I don't know too much about cars (Besides the basics and what certain things could mean). So, got it home, was checking it out. Revved the engine, and when it decelerated down there was a loud knock that sounds to be coming from underneath the car, I looked underneath and all that I can see which it could be (from the general location of the noise) is the engine or the pipes. So, is this a rod issue? Could it be a loose flywheel? I'm hoping we did not just buy a car to have to go scrap it to gain back some of our losses. Being as times are tough and money is tight.

5.4. So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:
2004 f150 cold start knocking noise - YouTube ....
Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!

Truck-2005 F-150 XLT 5.4L ... Problem - Currently when my truck reaches a speed of 45mph+ there is a methodical knocking sound that comes from the passenger side dash. This sound is on the interior and comes from the far right corner of the dashboard.(almost as if someone is tapping with there finger every other second). There is no correlation with anything else being turned on or off that affects this sound.(i.e. air) It simply happens once I reach a certain speed and is not an outside noise. When I slow back down under 45 mph the knocking subsides.

When you turn the interior ac temperature from cool to warm there is a loud knocking noise coming from under the dash. I am new to working on explorers but it seem like its coming from the black box nearest the firewall above the transmission tunnel. When you turn it to cold the noise almost completely goes away. The noise gets even louder when you mess with the selector for "max ac" "head and feet" "feet" etc.

2012 F150 6.2L V8... I am at a loss and I know that loud knocking is not a good sign. Two days ago my truck's low oil pressure light started coming on and off, so I pulled over and immediately turned my truck off. I called a friend at a Ford dealership and he asked a mechanic what I should do. He said it could be something as simple as low oil, bad oil sending unit or maybe something serious. So, he said check my oil level if low top it off and see if that fixes the problem. It was low and I topped it off, but the light kept doing the same thing.
Here's my dilemma; my truck wasn't making ANY noises (knocking, whining, etc...), 2 days later which was yesterday I was en route to get new oil/oil filter changed and 24 miles later I'm in a turning Lane and it dies! Will not start, but it tried, so I did not try anymore. I was able to get it into a parking lot and left it for about 4 hours and went to check on it and it started right up and that is when the knocking noise started. I turned it off and checked the oil and the level reads full...

Just had my 2010 F150 in for a loud knocking noise when the truck has warmed up in drive and rpm up to about 800. I can't hear the noise when I disconnect the passenger side vtc selonoid. The Tech who worked on it has recommended replacing the motor. His troubleshooting on the ticket says he removed the coil from the number 4 cylinder and the noise he hears goes away. I just can't see that the motor is bad.

I just got a 2003 f250 5.4 triton and it has a terrible knock. I've hear of the cam phaser problems but this thing knocks at high rpm and at idle so I doubt it would be a phaser, I thought it could be a rod bearing but I'm not losing any oil pressure. Its a pretty loud knock I don't have money for a mechanic to diagnosis it...

Whenever I cut the wheel to the left, there is a fairly loud knocking/grinding noise that I can feel through the floorboard.
Brakes have already been replaced, ball joints and tie rods inspected - no problems. Front end was greased (exception to the zirc fitting on the very top of the steering linkage). There is no modifications to the suspension (no lift) and the tires are the standard size (no rubbing in the wheel well). I do not know how long it has been since the shocks/struts were replaced but after inspection they seem to be in OK shape.
I read on this site that some owners were noticing a knocking under their floorboards too because of worn "body mounts". However, the body mounts are directly under the pedals. I don't feel any grinding or knocking under the pedals. It feels like its directly under the floorboard in front of the seat.
Could the body mounts be the issue when turning the wheel or is this something more sinister?
If its the body mount, it would be great if someone could post pics of the procedure. I have some pics that were posted from before but where to look on the underside of the truck to find the bolt/nut etc and where I put the floor jack and how high to raise the body...

I have a 98 F-150 which has a loud knocking at the passenger side valve cover. I am not a mechanic but thought it was a rocker arm knocking. I dropped some oil from the oil pan and did not see and metal shavings. I added some mystery oil but the knocking continued.Loaded the truck on a trailer and hauled to a mechanic to check for the problem. He said the oil ports are clogged and oil can not get to the cam shaft and the cam shaft bearings are probably causing the knocking. He said there is no way to fix this problem and I will have to replace the motor.
I called another mechanic and described what the other mechanic described. The 2nd mechanic said it would require a complete tear down of the motor and would be cheaper to replace the motor. I recently bought this truck just to use for hunting and around town since it already has 198k miles on it.
Is there any way to clean the gunk from the oil ports? The truck will still run but just has the loud knocking so I don't let it run for more that a couple minutes. I have been reading many opinions for sludge blocking the oil passages and am considering removing the valve cover gasket and filling with diesel and let sit for 24 hours then repeat then put in fresh oil and filter. Maybe this will clean the blocked passages.

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.

I have a 02 power stroke 7.3, driving down the road the other day is started smoking a grayish white smoke pretty good. i let off the throttle and it had a real loud knock along with the smoke. oil pressure was good. i stuck it in neutral and revved it up kept smoking but the knock would go away at higher rpm. then all at once it would stop and run fine. then today it started doing it and wont stop now at all.

I have a 2004 F150 with 195,000mi. For the last several moths the truck has had a rattle on startup, some days it is barely noticable and only on cold starts, other days it is loud and occurs on every startup. The truck was most recently serviced at the Ford dealer and is filled with Motorcraft 5w-20 syn blend and Motorcraft filter Every change before was either Motorcraft syn blend or Penzoil Platinum (I have always used Motorcraft filters on it) and the noise continued after oil changes so I don't think the drain back valve is the issue. I replaced the cam phasers, timing chains, chain tensioners, and guides about 15,000 miles (2 years) ago and the vct solenoids shortly after that. Here is an audio clip of the noise (I know the truck also has an exhaust manifold leak, I plan on replacing the manifold while im working on it
Is this noise the lash adjusters or have the cam phasers failed again (they were dorman parts)? If it is the lash adjusters, can they be replaced without removing the cams? will failed adjusters be obviously damaged? Should I also replace the cam followers? do i need to replace all 24 at once or can i safely replace only damaged ones or maybe just 1 bank (noise seems to only be coming from the pass side)?

I drive a '11 Sonata GLS and experience the rattling noise/clanking when weight shifts to the front-right of the car or when i go over a dip, and the noise is coming from the passenger side of the vehicle. I THINK it is the glove box issue that has been mentioned before and I am going to purchase some felt tape and apply this method [URL] .... that was posted here. Did this correct the issue?
And also when i reverse the car (specifically when I turn the wheel to the right) I get a knocking noise, which seems to also be coming from the front-right (or back) I can't tell. Can this be an axle? I'm at 79k mileage so the dealership wants $125 to diagnose the problem and that amount will go towards anything needing repair. Should I take the car to another shop instead?

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.

I would describe the noise as a low rattle/knocking when i hit bumps(or the second after). i thought it might be my spare tire knocking around in its trunk well under the carpet. I actually removed it and drove around to check, but it was not the issue. I had a mechanic look at wheels/suspension because of this noise, he told me the rear passenger side sway bar link needed to be replaced. I personally ended up doing the work and replaced the right and left rear sway bar links however the noise persists.
while the rear was jacked up i tried wobbling the wheels with my hands to check for play but found nothing in any direction. The mechanic seemed to think everything else looked ok.
I only notice it at low speeds like driving around a neighborhood. The big bumps it either isnt happening or the noise is drowned out by the general sound of hitting larger bumps. But over mildly bump sections such as a bad asphalt patch chop it can be very noticeable.
Its not very consistent, its hard to predict when ill hear it and its almost like its during when my suspension settles after hitting the bump that its heard.
