Ford 7.3L Power Stroke (1999-2003) :: Vibration Noise When Taking Off With A Load On Drive Line
My rearmost drive shaft u-joint is bad and has slop. I've been having vibration for about 7-8 months, but just started hearing a noise within the past week, especially when taking off with a load on the drive line (uphill or heavy acceleration). The vibration has not gotten worse, just that the noise has just begun to show itself.
I have one u-joint which is OE and has 275K miles on it, and it seems to be OK at the moment. The other two (including the rearmost unit) both have about 100K miles, as does the center support bearing.
Just because I don't want to worry about anything, I'm going to replace all three u-joints with Moog Super Strength units, and will also replace the Center Bearing with a new Spicer unit... just because I can and don't want to be pecked to death with multiple failures in the same drive line. I ordered the Moog joints because the only Spicer joints I could find were for the 4wd configuration.
That's the context... here's my question... The parts are on order and won't get here for several days. I've been driving the truck like it is at about 1500 miles monthly. Do I continue to drive the truck for another week before getting the joints and bearing installed? I know it's a guess... just looking for more perspective.
Ford 6.0L Power Stroke Diesel :: Vibration Coming From The Rear At 40 And 60 MPH
When I bought the truck it had some crap tires on it and the deal was that they had to put tires on it for me. I just picked it up and notice that I have a vibration at 40mph it then goes away by 45 then it comes back at 60 then gone by 65. The vibration feels like it is come from the rear.

I am experiencing a pretty noticeable vibration from the rear of the vehicle (steering wheel does not shake and I have no "death wobble") when hooked to my 14K trailer and also my stock trailer (to some degree). Happens constantly whether loaded or not, although it is a bit better when loaded. Happens much more on rougher country roads, but is still there on the interstates.
The trailer is new to me and I rebuilt the entire brake system, repacked bearings & tires have great tread, but have not had the tires spin balanced.
Can't tell whether a shock change (FX4 Rancho) will fix it or not.
I DO get a pretty severe roller coaster deal when hooked up and going over a dip. Truck just continues to bounce tail to nose, tail to nose, etc. That in itself is obviously shocks, but I am more concerned about the vibration.
Ford 6.0L Power Stroke Diesel :: Vibration Noise When Brakes Applied
I have a 2007 Ford F-250 6.0L that's making a vibration noise when I come to a stoplight with my foot on the brake, just idling. I just recently replaced the front brake pads this past weekend. I looked under the hood and visually checked for any obvious things that could be making the noise and did not find any, I did notice my power steering pump is damp with fluid. Now this noise only occurs when my foot is on the brake, anytime my foot is off the brake, it goes away.
I checked brake fluid level and power steering pump fluid level, both are fine except power steering fluid looks like chocolate milk. I don't know if the power steering pump would be the cause of this, but I'm going to replace it because it's leaking and I'm guessing the fluid for the power steering is way overdue. I've only owned this truck since March of this year and it has 128,000 miles on it. Hopefully this video link to youtube works, the sound in the video is the same noise that I'm hearing from the truck. Where this noise is coming from.

Ford 6.7L Power Stroke Diesel :: 2015 - Shaking Under Slight Load Due To A Small Incline And Loud Diesel Sound
So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
Ford 6.0L Power Stroke Diesel :: Vibration / Noise When Stopped After Truck Warmed Up And Been Driven A While
2003 with 2005 motor, auto trans. After truck is warmed up and been driven a while I get a vibration/nice when stopped. Sometimes the Vibration changes with the brake peddle application. Is there a ps hose that can go bad internally on these? Anything else to look for. It's easy to hear/feel in the cab but can't hear it under the hood. Changed the ps fluid with no change.

Since day one my 2016 F250 occasionally has a reed sounding vibration at highways speeds near the passenger side occupant handle on the windshield pillar. Talked to a service advisor at the dealer about it, what it could be, so this must not be a common problem . The issue is intermittent and can not be reproduced on demand. I tried blowing compressed air all around the area of the Windshield to see if I could reproduce the sound in a shop setting, but no luck. Only thing in common with this noise is 75+ MPH during a rather windy day. I'm a little reluctant to drop it off at the dealer since intermittent problems are hard to diagnose.

Ford 6.0L Power Stroke Diesel :: 2007 - Magnaflow Exhaust - Down Pipe Causing Vibration And Noise?
I just got a 5 inch turbo back Magnaflow stainless exhaust system installed on my 2007 F 450. The downpipe rests directly on the firewall and causes a horrible vibration and noise at times. I have been on the phone talking directly with Magnaflow trying to resolve this issue

I have a 2006 F350 Superduty hd 4x4 6.0 Diesel. When it begins to start pulling from a standstill, it will not build power to untrack the load. Once it gets going the turbo will build boost and pull fine. Checked Boots on tube from turbo to intercooler for possible leaks. Replaced tube from intercooler to intake. Made sure map sensor tube was clear of soot (none at all in there). Air Cleaner is in good shape. Im a little Frustrated.
View 7 RepliesFord 6.0L Power Stroke Diesel :: Whistle Under Heavy Load
I posted earlier about a whistle that appeared when I was towing my old travel trailer (6000 pounds). It only happened a couple of times, and I had a hard time replicating it, so I elected not to waste any money with the deductable, and possible additional costs for a non-covered issue at the stealership.
Now, I am towing a larger 5th wheel trailer (11000 pounds), and am experiencing this whistle on every steep grade, while towing. Below are a couple of things I noticed, that had to be, before I would get the whistle:
* It only seems to happen while the cooling fan is engaged, and also only when the rpms reached 2800 and above.
*If the fan was on, but the rpms were turning below 2800 rpms, then it would not whistle. It would, however, after the transmission downshifts, bringing the rpms back up, while climbing.
*If the engine was spinning at 2800 rpms, and the engine fan was not engaged, then it would not whistle, until the fan would kick in.
* It only seems to occur when I am climbing a steep grade, on a warm day. Although, I haven't experimented on steep grades on a cold day...
It sounds to me like there is an issue with the engine fan system, but I thought I would put it out there, just in case any of the diesel guru's out there might know of something else that would cause a whistle like this, i.e., turbo?
Oh by the way, I also think that I have a performance reduction lately. However, I can't know for sure, as I have never towed this much weight with my truck before. I just kind of expected that I would be able to pull to the top of these grades, with a little extra peddle to spare. I have to floor it, just to "try" and keep up with traffic. And I haven't calculated my fuel mileage while towing this beast yet, but WOW, that fuel gauge needle sure does drop like a rock!
Ford 6.0L Power Stroke Diesel :: Stalling Above Idle Under Load
My 6.0 stalls out when under load above idle intermittently. When it stalls, if I release the gas pedal and tap it, it usually catches again but not always. ICP is strong and doesn't seem to waiver when it stalls. Engine runs much better when oil comes up to about 180. Oil / water temp spread about 5 degrees.

After replacing both heads with remanufactured heads from ford along with new egr and oil cooler a month ago, she still overheats when pulling a load. While normal driving and not towing, no problems. In the last 5,000 miles since work was done and while towing approx. 15,000 lbs (load and trailer weight) she got hot once, slowed down, temp retreated got home - she has not overheated since then pulling 4-5 loads over the next 2,500 miles. Today at about 75 degrees only 4 blocks after picking up a load at about 12,000 lbs she started getting hot again. After I let her cool down and got on the Freeway the temp went down, appears she's not staying cool in the city with a load on. With all the work and new parts I had installed, what the problem might be?

2005 F250, 6.0, 60K miles, recently (within last 1K miles) had ARP studs, EGR delete and new oil cooler installed. Shortly after (5-6 weeks later) I noticed blue smoke under any load (taking off from red light, backing up) but not at idle or startup. Was using the "Performance" SCT canned tune after the stud install, but had the "65HP Tow" canned tune installed when I first noticed the smoke and now back to stock after noticed the smoke as a precaution. Everything else original except FICM, filters and batteries and use 5w40 Mobil 1 since new.

So pulling my trailer and 4x4 and the truck dies without any other symptoms. No check engine light all other electrical remains working. This happened 6 times this trip always while pulling a grade but only after the truck has been running for a few hours. Each time, no warning and once the truck has set for 5 to 10 minutes it start up like normal. The longer i let it set the longer I can run before it does it again. ICP is 550ish at idle, 200ish while cranking. Check the FICM before the trip and it was at 47.5 to 48.5v key on engine off and running. STC, stand pipes, dummy plugs, ball cups have all been done.

In the last 3 weeks I've replaced the oil cooler. IPR, ICP, fan clutch, intercooler, rebuilt the turbo, new elc coolant, egr valve, thermostat, new batteries, positive battery cable, and alternator and a host of other crap. Now I have a new problem.
When towing it overheats, almost instantly under load. I was towing a 9k trailer up a hill, a total of about a 30 second climb and it overheated (242 degrees). I'm thinking head gaskets at this point as they are stock and have the tty bolts installed.
Ford 6.7L Power Stroke Diesel :: Pinion Seal Leak And Now Shudder When Not Under Load
Recently had a rear pinion leak and replaced the seal and nut. I jacked up the truck, took off wheels and felt the drag so I could duplicate once i had the new seal as I tightened the nut. I've done this only once before on my F150 years ago, but when I put the driveshaft back on and test drove it, i had shudder when not under load. So when I let off of the accelerator, it had shudder and more the faster I was going.
Obviously thinking this is a preload issue with the rear axle but would this be caused by tightening too much or too little. I had no issues before so I would think that the driveshaft itself is not the issue. I can't confirm that I got it bolted up in the exact same manner as before in relation to the flanges but still wouldn't think that to be the issue.
Ford 6.7L Power Stroke Diesel :: Loud Clunk / Bang When Downshifting Under Load
38k and 15 months old. Runs fine except...
Can be in cruise or not, tow/haul or not, but need to be pulling a decent hill with 7k+ trailer. Running level with air bags. Regardless of speed, cruising at 50, 58, or 65, beginning incline and turbo boost builds normally to maintain speed to the point when it needs to downshift. BAM!!, not just a clunk, 90% of the time- scares the hell out of me. I can make it do it on an incline empty, but it it difficult. If because initial speed is 50ish, a second downshift to 4th may be needed. A bang only 50% of the time.
No codes.
Regardless of the degree incline, (toughest in the NC/KY areas is 6-7% grade, can avoid harsh shift by backing off on throttle and manually downshifting to 5th or 4th, depending upon speed.
Can "make" it do it on level terrain with 7k trailer if I slowly back off throttle and slow from 65 to 50 or so and punch it, but not too hard. Too hard and it goes to 4th, usually with just a modest clunk. Just right and I get 5th with a loud, and I mean loud BAM. Even the tech was impressed.
Afraid to hook up my 17k 5er and take off for the next 3 months, which is the reason I bought the truck to replace my 11...
Carrier bearing has grease coming out of it (400k on various duallies and never seen this), but dealer says not an issue.
Ford told dealer that it had no idea, and advised tech to do a lot of pin point electrical testing and everything checks out. Next stop is the inner workings of transmission.
I have been without it and work for 3 days because of backlog. Running two day load tomorrow, then back in for tranny work.
