Ford F-150 - 1997-2003 :: Loud Single Knocking Noise Coming From Behind The Dash When Turn Key On
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 (2004-2008) :: Loud Knocking Under Dash On Passenger Side
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.

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...
Ford Super Duty (1999-2016) :: Loud Knocking Noise Coming From Left Valve Cover Area Occasionally
I just picked up a 2001 F350 with the 5.4L with 200k miles. When I test drove the thing the engine sounded fine. I got it home and noticed that it occasionally has a loud knocking noise that is coming from the Left Valve cover area. It sounds like an old Chevy 6.5L Diesel ...
It comes and goes, Hot or Cold. It seems like it usually goes away when driving with RPMs above 1500 or so, however I took off with it yesterday and the noise would not go away, it seems like it might be low on power when the noise comes on, but then again it always feels low on power, so who knows.
I have changed the plugs, oil, and verified there are no exhaust leaks at the manifolds.
Here is a video of the noise: YouTube....
I dont think it is the timing chain, as it seems like its coming more from the center of the cover, when placing my hand on the cover near the timing set there is no vibration or anything that would lead me to believe its the chain.
All of my searching so far turns up 3V stuff, and little info on the 2V engines. The valve cover looks like a nightmare to get off, who have to work on these things (including me).
Ford F-150 (2004-2008) :: Very Loud Knocking Noise On Cold Start Up
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:

Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!
Ford - Explorer :: 1998 - Loud Banging Noise When Driving Coming From The Rear
My 1998 Explorer is making a terrible banging noise when driving. It appears to come from the rear. It only occurs when i step on the gas, gives a bang and the car shudders lightly. The bang can be gone for 10 - 30 seconds, and all of a sudden appear again. If I step hard on the gas, it will make a bang! bang! bang! noise.. If let my foot off the gas, it rolls quitely without any noise.
I have greased the slip yoke, inspected the U-joints, checked the rear calipers, opened the rear axle/differential plate - no metal parts or excessive wear were observed.. The transmission runs smoothly, there are no other noises apart from the bang. It is as if someone is hitting the car with a hammer from underneath...
Santa FE SM (2001-06) :: 2004 - Loud Knocking Sound Coming From The Top Of Engine
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...

View 8 RepliesFord - Explorer :: 2004 - Acceleration Responding Slow / Tick Or Tap Coming From Behind The Dash
We have an 04' Ford Explorer NBX 4x4 (auto). We are not the original owners. It has a several issues.
1. Acceleration seems to be responding a little slow when I depress the accelerator pedal. Like a lag of some kind. Engine appears to idle and run fine. Just that subtle lag from gas pedal to engine response. No trouble codes
2. There is a tick or tap coming from behind the dash. This morning as soon as a put the key in the ignition the ticking started but went away after a few minutes on the road. But comes back when I come around turns (like a rounding off ramp from the HWY). Cannot figure out what it is. No trouble codes.
3. My transmission (4x4 Auto) when cold is fine, but when it warms up it seems to go into 4x4 mode and wont come out. All I have to do start going up a subtle hill (or incline) and it engages the 4x4 (at least that's what it feels like). I can hear the sound of gearing. When the transmission shifts it thumps really hard. At low speeds when I let off the gas it thumps really hard. We took it to the tranny shop and they said it was the rear end.
So we had that rebuilt. It was ok for a couple of months (rarely drive it). But it is doing it again, but seems to be getting worse. When in this mode it seems to feel like its dragging. We recently serviced the transmission filter. Replaced fluid. We reset the computer to relearn daily driving. But didn't work.
I was thinking of replacing the 4x4 module and or solenoids in tranny, or 4x4 motor on transfer case, but I don't want to spend money if it doesn't fix the problem. No trouble codes. Are all these issues related to one another? Is one issue causing the other problem to exist?
Ford Wiring/Electrical :: F250 - No Power / Loud Buzzing Noise Coming From Under The Dash
Tried to start my truck after sitting for 2 days in sub zero weather. wouldn't crank. pulled the batteries and charged them over night. Tried to start it the next day-wouldn't crank but the starter relay clicked. Was going to pull the starter and check it but decided to replace the relay first. replaced it and tried to start but now have no power to the cab-nothing comes on. I've checked the batteries with a load tester and they are ok. I've checked the fuses and they seem to be ok. when I tried to start it and the relay clicked there was a loud buzzing noise that seemed to be coming from under the dash. it has done this before but this time was louder than usual. I live out in the sticks so taking it somewhere is a last resort. It is a 1999 7.3 with 290000 miles.
View 14 RepliesSuzuki - Aerio :: 2004 - Loud Popping Or Knocking Sound Coming From Front Of Car When Driving
I have an '04 Suzuki Aerio, and there is a loud popping or knocking sound coming from the front of the car when I drive it. I don't seem to hear it when the car is inert (i.e. idling or traveling in a straight at a constant speed). I hear it intermittently when I accelerate/decelerate or turn. I hear it in drive and reverse. The strange thing is that it seems to go away completely when it is raining, and then come back when it stops raining and things dry out. It has been happening for a month or two. I think it has been gradually getting a bit louder. What could cause this?
View 6 RepliesFord - Explorer :: 2004 - Loud Snapping Noise When Backing Up
So my 2004 explorer 4.0 XLT sport has a strange clicking noise every so often. I first noticed it when I back out of a parking spot, at one point almost every time I hear a loud snap, sounds like a bolt breaking. Wheel is turned and backing up.
If I get out and have wife do it of course the noise is gone and doesn't reappear. Also if I drive down a parking lot slowly I can hear a clicking noise if I roll the windows down. This sounds like a nail in a tire, click, click click at regular intervals.
But, put the rig on a lift and you don't hear anything. Nothing, I am thinking I have a damaged axle up front but don't see anything out of the ordinary. No torn axle boots, no looseness, nothing. It's a 4x4 not full time so even in 2wd the front axles are turning.
Golf/GTI VII :: Very Loud Relay Ticking Noise Coming From Dash
Just noticed this about a half hour ago when I left a friends house, first time it's done it and does it every time since. Sometimes it only clicks 3 times, sometimes 5. Possibly the motor/actuator that controls the inside/outsider air valve?
View 13 RepliesPrius (2004-09) :: Loud Knocking Noise When ICE Running And Car Is In Drive
I recently bought a 2007 Prius that is making a rather loud knocking noise that has me a bit perplexed. I know the noise is not normal as my 2005 does not do this.
The noise only happens when the ICE is running and the car is in drive
If the car is in park and you rev up the ICE the noise is not present. With that said I do not think the noise is isolated to something in the ICE as I think it would be present when revving the engine in park.
However is you put the car in drive and step on the brake (to keep the car stationary) while lightly revving the ICE the noise is present. The noise is present every time the car is in drive and you accelerating, even with the lightest of throttle.
It does not need to be under excessive load and with that said I am certain it is not spark knock/per-detonation of the fuel nor does it have the "pinging" sound like a spark knock.
If while driving down the road and the ICE shutdown down while driving at lower speeds the noise disappears. When the ICE starts back up the noise reappears.

View 8 RepliesFord F-150 (2004-2008) :: 2005 Lariat - Knocking / Dieseling Noise Coming From The Passenger Side
Having issue with his truck. He bought it 3 months ago and has no history. 166k. You now know as much as I do about the truck! He knows little about automobiles so fact finding has been difficult. I have done all my own work on countless US and foreign automobiles over the last 30 years and never take my vehicles anywhere. I will try to post as much detailed info as I can. I have read tons of posts now on various forums so I am up to speed on VCT and phasers.
This one seems similar, but not exactly the same symptoms which is why I am here. I have already pulled the VCTs and found the passenger side missing the top screen. I swapped them from side to side which made no difference. I checked ohms and they were at 15 which is normal from what I read. They were very clean and moved easily when I took them out so they were not gunked up so I don't think that's the problem. It idles very smoothly and isn't rough at all.
I have posted a video of the knocking/dieseling noise (link below) coming from the passenger side. The knocking starts as soon as the truck is started hot or cold (outside temps right now 70F-90F Houston). I can make the knock disappear by gently depressing the gas pedal going from idle of about 650/700 to maybe 750/800 and it will go away completely as long as I keep it gently depressed. As soon as I lift up it returns.
If I rev it up to 2000-3000 rpm it does not knock, however, as soon as I lift off quickly, it seems to knock at a high speed, hangs for a second and then knocks all the way back to idle. However, if I rev up and then lift off very slowly, it will not knock. I have tried to locate the exact location of the knock, but doesn't exactly seem right at the phaser, but actually back around the 2nd and 3rd spark plug area, but I can't tell exactly. I've had a couple people tell me the same when I asked them to tell me where its coming from. The noise is bouncing around in there so difficult to pinpoint exact area.

I wanted to get some second opinions on what this could be so I know where to go next.
Ford Explorer :: 2004 - Squeaking Noise Coming From The Right Rear Tire
2004 Ford Explorer4.0140k miles... For about 3 weeks or so i have been having this squeaking noise similar to the noise you hear when your breaks are worn out and you need to replace them. It sounds like it is coming from the right rear tire, i have changed all breaks all the way around and today i finally changed the rear passenger caliper thinking that it was causing the noise but it is still there. I am also driving on my spare which happens to be the same size as my regular tires it just does not have the rim on it.
I also found out that prior to changing the rear passenger tire it was wobbling and i did not know till a friend pointed it out, the rim does have a really minor dent but i am not sure if that was causing it to wobble or if the wobble is what caused the noises to appear. I have been driving the car for about 3 months and it started 3 weeks ago. There is also a clicking noise that i hear but i cant point out if it is coming from that side of the car, i can only hear it when i am driving slow.
Also the squeaking comes and goes, it is not always there and when it is there and i apply the breaks it is still there. I have done some research and a lot of people have a similar problem but the noise will go away when they finally apply the breaks, my noise still remains even when breaks are applied. What it can be, i did a little more research and now i am thinking it can be the ujoints on the driveshaft?
Here are a few pics of the dent i was talking about on the tire, could this minor dent cause the tire to wobble.....
Prius (2004-09) :: Knocking Noise Coming From Passenger Wheel Area?
We have an 07 Prius with around 150,000 miles on it.
A couple of weeks ago I noticed a slight knocking noise coming from the passenger front wheel area mainly when I was turning toward the right.
Question.......So when turning to the right, it first seemed to me that the right side would experience a heavier load. However, after further thought and applying some physics the inertia of the car would actually be putting a heavier load on the left side during a right turn. Which is correct?
Just trying to troubleshoot the noise/problem.
#1 when I apply the brakes, the noise doesn't change. I don't think it's brake related.
#2 the noise speeds up with speed, meaning that it's rotational.
#3 The noise does get louder when I am turning right but has know progressed into a constant noise going straight. During a left turn it subsided.
#4 I did take my floor jake and jaked the pass. front wheel up but didn't see anything broken or damaged. I couldn't rotate the tire though.
#5 I also had the tires rotated today and the noise got worse.
