Ford - F150 :: Knocking Noise Coming From Lower In The Engine
Feb 19, 2012
Recently, I was stopped in my 03 F-150 with 124,000 miles. All of the sudden one day, the engine started knocking. The knocking was coming from lower in the engine. After sitting for about two hours, I started it again. At first, no knocking, then intermittent knocking, then steady and after about 3 or 4 min, the knocking stops all together. Oil level has always been checked and it has never run low on oil. What on earth causes an intermittent knock?

Just had my 40k service done, and also got an alignment done at the same time. On my way back from the dealer I noticed a knocking noise coming from the lower rear area of the car which is more noticeable when going over bumps. Its intermittent. Thinking something got messed up when they were doing the alignment? What this might be?

I got in my 1977 f150 V8 windsor the other day and headed down the road. All of a sudden I started to hear this sound that only way I can describe it is a big log chain moving around or a box of washers being moved around. I got out, popped the hood and thought at first that it was a pulley somewhere on the front of the engine, perhaps water pump pulley or something like that. The closer I got my ear to engine though I think it is coming from the back passenger side of the engine, not the front. I could be wrong about that, but I do know it is coming from the passenger side of the engine. Sometimes it will go away for 1/4 of a mile and then come back. I also noticed that it gets faster when I give it gas and slower when I don't, which is why I was thinking it had to be one of the pulleys going bad. I'm not so sure though because I think it may be coming from the passenger back part of the engine.

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.

Few days ago I noticed the noise coming from the engine.
Went to dealership. They removed the oil pan and found metal shavings there .The car has 90,000 miles. They will put a new short block (will be covered by warranty ).
Since they basicaly will disassemble the whole engine, I thought to ask them to replace also drive belts, timing chain tensioner, not sure if the short block comes with the water pump , will ask them . W

2005 V8 TREG 74,000 miles ... Just last week.... My T-reg started to hear this knocking noise which seems to come from the engine on the driver side... I would say lifter sound but hoping that's not the issue. I do notice that when i start the car, no noise but when driven on the highway... I hear it especially when i come off the highway. On regular street drives, it takes a while for the noise to come up. I've had the Treg for about a year now and havent had any problems but this. I drive the car during the weekends and sometimes during the week.

It's a 2006 hyundai sonata LX.
Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.
This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

My 2012 with 5300 miles on it (oil change at 4400 miles) is now making a pretty significant lower end knocking noise at WARM STARTUP, as in when the car sits for about 10 minutes when I go into the store. It lasts for about two seconds, but it's significant and it's loud. It seems to have started about 500 miles ago and I can't say it was due to the oil change. Oil level is full and clean - I check it every weekend, even on a new car. Could this be a timing chain noise? Don't know. All I do know for certain is that this is very irritating and embarrassing for a new car. People around my car when I start it look at me like and seem to say "Really?"
Cold startup on my car is actually surprisingly quiet, compared to my Nissan Frontier V6.

I have a 2003 F150 SuperCrew with 180k. Has been a great truck. Last fall the check engine light came on, and I took it to Advance Auto and they said to replace the lower O2 sensor. Did that and light stays on. Ever since then, and getting worse, is when I crank truck, it idles very rough, and if it sits too long it will just "choke itself out" and quit. Recently this has happened while driving on road too. I have to shift the gearshift to N to crank it. I get power but no crank if I try it in P.

I just got a new clutch and clutch slave cylinder in my 1998 Ford Explorer. Driving it home from the mechanic, I'm hearing a sputtering sound coming from what seems to be the lower part of the engine compartment. It sounds like a VW Bug exhaust. I've never heard this sound before. It's troubling that it has appeared now immediately following a repair. I presume there is a outside possibility that it's not the mechanics doing, but that seems improbable. (The engine was revving high right before the clutch blew out last week, so maybe those brief high revs caused some damage? I can't imagine that being the case.) Or was there something in the clutch repair process that could have resulted in this?
I made a recording of the sound here.......

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?

2008 F150 4x4 27000 mi There is an intermittent metallic /rattle sound (like marbles or a chain in a can) seems to be coming from front passenger side; sometimes on first acceleration , sometimes after turning a corner, sometimes after hitting a bump. Doesn't last more than a few seconds Had my mechanic friend look at it on hoist and no apparent loose parts in exhaust system or breaks; 1st noticed it last August ( 7000 miles ago) but it subsides and then reappears with no distinct pattern. best guess is a bad wheel bearing but it's never gotten any worse; other guess is transfer case/ chain problem but 4x4 use isn't much and it goes in and out of 4x4 mode with no problems.

I've got a 2006 f150 4x4 v8 ... I get a grinding noise (I think it is coming from the front left of the truck) that lasts only a little while and only comes out after a cold night (so I only get the noise in the morning after the truck has sat overnight)...
The issue details:
1. The grinding noise is constant and the truck has to be moving for it to make the noise
2. The truck will only make the noise while driving forward, it disappears when I drive in reverse
3. The truck has to sit overnight and it has to be cold (below freezing)
4. I only get the noise if I go in reverse BEFORE I drive forward after the truck sat all night
5. Will not make the noise while in 4x46. It has been doing this for about 2 months
What I tried:
1. Replaced both front wheel hubs
2. Replaced 4x4 vacuum and checked the lines for pressure
3. Front brake pads and checked calipers
4. While the truck was making the noise unplugged the 4x4 vacuum - still made the noise

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...

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.

I purchased a new 2011 F-150 Lariat, Ecoboost, SCrew, 4x4 last weekend. I love the truck. It is very comfortable, the Ecoboost has been incredible, and the ride is very nice. I am looking forward to towing my ATVs after I hit 1000 miles.
Yet, I have one problem. I get an incredible amount of wind noise and wind whistle from what appears to be the driver's door. I read other posts about wind noises and wind whistles (e.g., bug shield), but they do do not apply to me.
I'm planning on dropping it off at the dealership this week for them to take a look at.

My mom was driving to pick me up and she said that all of a sudden about half way here that the car started making a knocking sound and white smoke started coming from hood, the car was also trying to shut itself down while she was trying to pull over. It is a 2000 ford taurus with like 130k. I am so scared that it is the head gasket because my mom, myself and my daughter, and my 16 year old sister all share that car to get around. Is there anything else it could be besides that or is that probably what it is?

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.
