It clunks real bad at random times. Whether I have had the e-brake on or not (sometimes even with it on, so I have not put any load on the locking mechanism in the tranny).
Its a 2014... Does not matter if its inclined ground or flat.
My 08 F350 V10 it replaces never once clunked.

My co-worker has an 06 F250 SC 4x4 and is getting a P0713 code. 2006 Ford F250 6.0L Diesel ... Tow/haul light comes on flashing at random times. Truck is reading a P0713 code which is the TFT Sensor Failure/Replacement
Ford dealership is telling me that I also have to pull the valve body and install the new upgraded wiring harness (3-3.5 hours labor) but a thread on this forum stated I just needed to replace the sensor in the tranny pan and reconnect the wire harness. Do I need to upgrade the wiring harness?

Yesterday my truck began to give me some problems starting. The engine turns over just a couple of times then it sounds like the starter disengages and winds up. it took multiple attempts but it finally fired up. Does this sound like the starter or could it possibly be the starter relay?

Recently, my Explorer will sound like a cessna first thing in the morning, and then at random times through out the day. Then, the other day, the temp spiked on my wife. She pulled over, and let it sit for a bit, started it back up, and haven't had a problem since with temp. We only hear the sound on acceleration, and I have noticed that my F250 does it sometimes also, but not to the same extent. Is this normal, or a sign that the fan clutch is bad?

I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.
Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?

I have a 2006 F350 6.0 Diesel with 125,000 miles.
1st issue....When accelerating the fan comes on and it sounds like a jet engine taking off. Let off and it goes away! It acts like it does when you're towing something and put it under a load but you're not towing anything?
2nd issue...when towing a month ago hit a hill and totally lost power it was down to 25-30 miles an hour with it floored. Tranny gauge got up to about 3/4 but never any further. Let off pedal to try and get new gear and did not work, was like it was in a limp mode but never threw the wrench up. Finally got to top of hill and she cruised down other side just fine. No loss of power tranny back to normal. Then towed over weekend on flat land and tranny gauge went almost to overheat. Didn't seem to have power issue.
Since 1st tow issue it had 8 new injectors installed but hasn't seemed to change much. Fan issue was there before injectors and new injectors only, worked only with the cutting out it would do when cold and when driving in overdrive. Computer issue? Relays?

So I started my truck this morning and it sounds like air rushing out from the driver side of the engine. I currently have my ICP unplugged due to a bad sensor, will be replacing it on Sat. Also I have been having an issue with my turbo but I don't think that it's related as I here the air rushing sound when at idle as well at when driving. It seems to be a bit louder when the engine is cold but I could also be crazy about that.

My 2004 powerstroke recently started making a loud knock during the process of starting. Will make the sound warm or cold, however I mostly hear it when the truck is warm as it cranks a little longer and about two seconds into the crank something starts knocking. After the truck starts it runs perfectly fine.

I have an 03 Excursion with 220,000 on the clock. Started getting harder starts randomly about a month ago, maybe a little more, pulled codes got p2290. Reset everything, changed the oil, oil filter, both fuel filters, eventually the ICP sensor itself and rebuilt the IPR with new screen kit and rings. Hard start went away for about a week but ICP pressure was dropping drastically during hard throttle or even trying to go up a good sized hill. I had a bypass oil filtration kit on and noticed that the connection on top of the oil filter housing was weeping at idle and leaking enough at throttle to possibly cause an issue. Replaced with new OEM filter cap and fill cap, and ended up with a no start and low ICP pressure.
Got it started today after a long crank (15+ seconds), ICP and IPR at idle both warm and cold are mid 600's and low 20's (I can get actuals if needed). After reaching operating temp starts fine after shut off (both immediate and after sitting for 20 minutes). I picked up a selection of parts and tools including an ICP air test tool. Also grabbed a hpop gasket kit and the updated O-rings for the whole system. Live scanning wise I have an Edge CTS and also an SCT x4 that I can use.

No complaints about the driveability of the truck, runs great, drives/stops straight, etc.
However, when driving really slow (<3 mph), and I put the window down it sounds like I can hear what sounds like stones in a hubcap. Sound seems like its coming from wheel area, not sure where. Not very loud, have to turn radio off, put window down to hear it.
Just had tires rotated about 1000mi ago at the dealership, they checked brake pad thickness(about 50% left).

I have a 2015 F350 6.7 DRW King Ranch with approx 12800 miles on it and have recently developed driveline noise which sounds like the rear axle is binding when backing up to the right. The truck has the 3.73 limited slip differential. Not sure what could be causing this. The front hubs are in "Auto" and the truck is not in 4-wheel drive. I don't notice the noise when moving forward, only when backing up to the right or left. Never noticed the noise when backing in a straight line. For whatever reason, when backing up to the left, the binding noise is not as prominent as when backing up to the right. Binding noise is most noticeable when front wheels are turned hard to the right.

Had a hot no start going, found dummy plug issue, replaced dummy plugs. While in there I cleaned the injectors (passenger side only) and put back together. Cranked multiple times, had to recharge batteries a few times as it is in the 10 - 20 degree temp range. No joy on re-start following the work.
Numbers I'm getting are:
KOEO With ICP connected:
ICP - 0
ICV - .07
IPR - 14.8
While cranking
ICP - eventually builds to 400+-
ICV - eventually increases to .13
IPR - maxed at 84.7
ICV too low so...
After disconnecting ICP
KOEO
ICP - 0
ICV - 0 (disconnected)
IPR - 14.8
While cranking
ICP - up to 1693
IPR - to 65.5
Still no start.
Ran through FICM check and the numbers are fine - 48 key on, 47 key during buzz, 47-48 while cranking.
I do get oil pressure registering on the dash gauge.
Fuel is in the filter housing
Oil filter housing refills with oil as expected when cranking
Only code is the P2285 once the ICP is disconnected

I noticed a rough idle after driving an hour with a 6000 lb trailer and stopped at an offramp. Had no performance issues to that point in an hour drive. Then I noticed a good amount of white smoke coming out of the exhaust. The idle felt just like when I had a contribution/balance code on #5 a year ago, and a new injector fixed that. Before long (10-20 minutes later) the idle got real loud, like a big knock/loud tick every revolution.
I had a bunch of stored codes, so I reset them and later found a P0281 - Cylinder 7 contribution/Balance and P0404 - EGR control circuit range/performance were the 2 that came back. I drove it 2 more hours to get home. It ran well under load, but coasting or stopped gave the loud knock, and stopped and idling was a rough, inconsistent idle. It even stalled on me 3 times when braking for a red light (auto trans). There was a lot of white smoke all the time, plus a little dark smoke on acceleration.
What would you recommend for troubleshooting steps? I could put a new injector in #7 and clean the EGR valve, but want to have a good idea that will fix it first. Is there a good chance I have a messed up piston in #7 now?
Codes I cleared:
P0148 Fuel delivery error
P0234 turbo overboost (i know i need to pull and clean the turbo anyway, unrelated to today's issue)
P0281 Cylinder 7 contribution/Balance
P0404 EGR control circuit range/performance
P0670 Glow plug (I had the module unplugged a while ago)
P0683 Glow plug (I had the module unplugged a while ago)

I know this is an old subject that comes up from time to time. Most will notice it after an oil change or the first oil change anyway. Yet, some will never notice or experience the sound.
It is when you first start the engine, it has been described as a can of marbles being shaken or popping noise, maybe a metallic knock.
I have 17K on the truck now and this seems to be getting louder and more annoying. Sometimes it is louder than other times, and sometimes I don't hear it at all. I have always changed my oil right at 5,000 mile intervals. Fuel Filter at 13,500.

Had extreme cold weather here and I left my truck unplugged for a couple of weeks. Started fine but stalled once the fuel was used up in the lines. Replaced fuel filer and filled with that anti gel stuff. Truck sounds like it is almost firing up but still cannot get it to run. When I turn the key on it sound like the fuel pump is working for about one minute and then turns off. Made sure the fuel filter was overfilled with deiseal. Turned it over so many times the lines should be full by now. I used that quick start stuff and it almost starts every time.

Lately my truck has been smoking at random, it's not very often & only seems to happen while stopped with transmission still in gear (traffic light, etc). And at this time, I believe its a faulty fuel injector (still originals) although not confirmed.
