Ford F-150 (2004-2008) :: Loud Knocking Under Dash On Passenger Side
Feb 15, 2011
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.

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.

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.

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.

There is a knocking sound coming from the passenger side dash board in my 2010 Taurus. I found a youtube video that indicated in was a recirculation door motor. I replaced that but the knocking is still there.

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!

I bought the 2013 GS 350 F-sport thinking it would be a long lasting reliable car.... I've had brake squeal since day one. My car now has 45k miles on it, all miles driven with the insanely loud brake squeal. It's been to the dealership many times but they've change the brake pads only once and refused to resurface or swap the rotors. After I called Lexus corporate and filled a case, I finally got the managers attention. (1800-25lexus for those in need)
The manager tells me that the brake squeal can be caused by the drivers driving pattern. He basically said that if you don't drive hard enough or maybe even drive too hard, the rotors will glaze over and you will get squeal. -so let me get this right, I have to drive a certain way all the time so I don't get brake squeal? - Long story short, he asked me to come in again so he can see the squeal himself.
Aside from the brake squeal..
-My front and rear passenger side shocks blew out and were replaced at 20k miles.
-I've had a rattle in my passenger side dash since 10k miles that the dealer refuses to fix. They say trying to fix it will cause more rattle.
-My back up camera is now pointing too low. Every time I go in for a fix it just ends up happening again after the fix.
-My rear view mirror is loose.
I can deal with the small things but that damn brake squeal is so loud that it actually pierces my ears when I brake next to a car with my windows down.. Brake squeal has now started on my sisters 2014 is350 f-sport as well. How I can fix the brake squeal so I can sell the car?

This happened last year right at the end of winter and than stopped during summer, just started back up today, just so we have all the info- my airbag light in cluster comes on and airbag off light come on above radio and both turn off. Once the truck is started a very loud ear piercing single tone comes from under dash (130 dB at least) this can range from 5-30 seconds depending on how cold it is outside.

I have an 08 Sonata GLS and today an annoying rattle was coming from what seems to be deep in the dash on the passenger side. I checked the glove box, closed all the doors tight etc. etc. but it is still there. It seems like a vibration as it is pretty constant but it does change going over bumps etc. Is it a known issue?

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've put a recording on Soundcloud:
The noise is best heard at 1:00 onwards, after everything else has stopped. I left everything else in the recording, the volume level relative to the engine etc.

I have an exhaust leak on the passengers side of my 2006 F-150 5.4 triton. If I do the repair which is the correct way to do it? Do I replace just the blown out gasket?
Do I need to buy a new exhaust manifold and gasket kit, with exactly what parts should I buy in the kit? Or do i need to replace both sides?

I have a 2004 FX4 and have a very annoying rattle up in the driver's side dash area near the windshield. This happens every time it gets to be winter. The odd thing is, that it will sometimes go away but when I hit an uneven surface such as a railroad crossing, I hear a loud "pop" near that area. Then it will rattle non stop. I don't know if it is the wiper cowling area or what? IMO Ford's design of that area is crap.

So there is a loud humming sound as I would describe, coming from the passenger side glove box when I turn my fan to run at high...

I drive a 2004 Hyundai Elantra with 72,000 miles on it. For the last few weeks, I've been hearing loud thud sounds on the passenger side when the car is cold or fairly cold. It almost sounds like someone is throwing tennis balls at the passenger side door while I'm driving. It happens when I'm stopped or when I'm driving - either way. Today, the Check Engine light went on; I don't know if it's related.

I just bought a 2004 4.2 V8 Touareg with issues. Engine has oil. Tried to start it but no start. I could hear a loud ticking from passenger (right) side cam upon cranking. I removed all plug wires from right side cam and now it starts and runs on drivers side (left) only. Getting spark from all disconnected wires. Car will drive forward and back and check engine light flashes. Reconnected right side plug wires and no start.
I notice one of the plastic intake manifold arms connected to a rubber bellow was broken. I assume that's for O2 sensor/warm up so probably wouldn't prevent the engine from cranking.
What do I do next? Remove valve cover and look for camshaft damage? Bad cam sensor cause this? I'd rather not drop a rebuilt motor in it but I also don't want to throw $5k of parts at it. Car is for my soon to be 16 year old son (maybe it's safer as a four banger!).

Tonight I left my wife in the car as I ran inside a store, when I returned she said the car was making a weird noise. I didn't hear it until later after we were moving, but she was hearing it sitting still, no engine idle (battery at 5 bars) but A/C was running. I am suspecting maybe it has something to do with A/C.
The noise sounds like a low grumble rubbing. She said at first she thought someone was rubbing something against the car. But it seems to be coming from the passenger side dash, like behind the top glove box.
