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.
View 3 RepliesI ran about 500 miles today loaded up pretty good and noticed every bump I hit that was enough to rock the truck and trailer that there was a noise I've never heard before. It was like the difference between asphalt and concrete road surfaces, but was only present when the springs were sufficiently compressed. Temps were between -10 when I left to 10 or so above when I was destinated. Would that cause the noise?
View 3 RepliesI 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.
I have a pretty good leak coming from the front of the rear diff. is this a common problem on the 10.5 ? How hard are these to do without a lift? I still have warranty left but will have to swap out exhaust so its almost a toss up whether I do the seal myself. Also was considering a new posi unit because seems like the original is about toast, might be a good excuse to swap a new one in. 2009 with 95,000 on it. Bought it a year ago with 70,000 on it, the rear was dry till at least 90,000. I serviced the fluid at about 90,000 and didn't have a leak so now a couple thousand miles and its gushing???????
View 7 RepliesI just purchased a used f250 6.0L a week after having it i noticed a small oil leak slowly got worse (looked as if it was coming from the too rear of the engine) then noticed about a half quart of oil under my truck. While driving it home the oil pressure gauge kept dropping then going back to normal then eventually dropping for good. The truck still ran so i drove it to take it to the mechanic but then the throttle began to become unresponsive and then gain power again then finally the truck shut off and wouldn't start again, blowing oil all over the inside of the hood and top of the engine. I checked it and noticed the pressure sensor pigtail were fraid so i replaced that along with the sensor and added oil but still wont start.
View 10 RepliesI have developed a leak coming from the top, driver side, rear of my engine and I could not figure out where it was coming from. I took it to a reputable shop for diagnosis and they tell me that the rear leak is coming from the transmission lines.
The weird thing is I never thought the leak looked like ATF. They also told me that it looks like the stock radiator/cooler has been bypassed so I have no cooler.
Should I assume that the stock internal cooler failed and that is why the PO bypassed it? Also is there a decent write up on deleting these lines and running soft transmission lines to a aftermarket cooler?
So I went to the car wash this morning and when I pulled into the stall I heard a somewhat loud rattle coming from my front drivers side wheel. It sounded like there were a couple stones in the cap that covers the lug nuts. That wasn't the case. It did it in reverse also. Before I take it to the dealer Monday morning. Its a 2011 F-350 6.7 Lariat 4x4 w. 32,000 miles. I also have have a little whine coming from the rear when I take off from a standstill.
View 4 RepliesWhile servicing the bosses 121k 6.0, I noticed the coolant resevoir empty. It took 1 1/2 gallons to bring to proper level. Returning under truck to install drain plug, I noticed coolant coming from rear of the engine(right side). And of course Ford has changed the cooling system cap, so I wasn't able to pressure test it to pinpoint the leak. Started the engine and seen coolant coming from the left rear as well. I've been reading here to see what others have been seeing, (EGR cooler, head gaskets). With all the heat shields,not much room to look.
After work I did go and buy the adapter to test the cooling system. With any luck I will be able to see leak better.
I just had the Local Ford dealer perform an oil change. I noticed the motor running a tad different almost right away but put it off thinking it was something else going on. well i get several miles down the road and anytime i accelerate there is a noticeable vibration and little power. I also noticed that both my water temp and EOT were above 200*. I called the dealer and of course the service department had gone home for the day. I will be calling first thing tomorrow morning.
My drive from work to the dealer is well over 20 miles and at 60-65 my water never got above 189 and the EOT never got above 195. so after oil change water temp got to 205 and EOT was at 215 at the max. This is with no load going 55 mph on the hwy. I have a Ford Premium warranty on the truck as well and this is why I decided to have them do the oil change. they have done the previous oil change as well with no issues.
I have been chasing this vibration that seems to happen around 50 to 60 mph. It seems to be the last 2 gears in the transmission. It's not really a chatter, but more like a drive line vibration. At 70mph it goes away completely and is smooth as glass.
I have had the driveshaft rebuilt once, and just recently balanced. I am convinced it is not in the driveshaft. While it was being balanced the tech removed the harmonic balance r weight that was on the rear part of the shaft. Now the vibration seems magnified.
I was thinking it may be the clutch that is incorporated in the torque converter. Is there any way to disable the clutch just to see if it is the cause of the vibration? The truck had a lift and big tires on before I got it. It is now back to stock. It's a 2005 F250 crew cab short bed 170k miles.
172k on the girl now. Getting a little vibration while driving yesterday. Looks like it's time for new U-joints, carrier bearing pinion seal. Thinking of going grease less again since these lasted 172k. What brand should I go with? Or should I install ones that are grease able?
View 1 RepliesSitting at a light. I noticed a slight vibration while in gear. Get home. Put her in park and noticed it again. Took her for a spin again. It seems to do it at low speeds, cruising and goes away once I'm on it? What would be a good starting point to track this down?
View 2 RepliesI don't think I've really noticed this before, but I filled up my 50 gallon Titan tank and added a full 32-ounce bottle of Power Service Diesel Kleen (treats "up to" 100 gallons) before hauling some stuff and running through that tank in a weekend. I didn't really intend to but wasn't paying enough attention and put at least 3/4 of the bottle in and said screw it and let it have the rest.
I don't know whether that has anything to do with it, but since then I've noticed at idle it seems to have kind of vibration at idle, like a low frequency buzz. At speed it appears to go away. It's not horrible or anything, just noticeable, made more so by a flashlight I had in the hard side pocket of the 4-cup center console buzzing against the plastic.
What could be causing it and how to treat it? Doesn't seem like something worth taking to the dealer even though I'm still a little under the 36k mile original warranty.
I replaced the all 6 tires and all 3 rear u joints on my 03 dually and steering all feels tight but I still get a vibration above 60.
View 14 RepliesI currently have the rear axle shafts off the truck. I took off, cleaned then put on the rear diff cover.
I live in an area that does nothing but form rust anywhere and everywhere in very little time.
I don't want rust forming in the rear diff gears - can I fill the rear diff up ? Or will it leak out of the rear shaft holes ? Can I fill it up halfway then ?
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.
Vibration noise powerstroke - YouTube....
I've mentioned in the recent passed a vibration I have and thinking it may be one of my hub bearings. Now I really can't tell if it's that or something else as it feels like powertrain when accelerating but at speed feels like I'm driving on gravel?? The vibration is a tight one if that makes sense..it's bugging me to death.
View 14 RepliesI recently had a flat tire - Schwabs fixed it. Then told me my rear brakes were bad so I replaced them. I noticed when coming to a stop the last 20-30 feet you can really feel the front end vibrate - almost like it is in 4wd but it is not. I checked the hubs and they are on auto and lifted the truck to spin the wheels and made sure everything was dis-engaged. My front rotors were bad so I replaced them and the pads thinking it was the root cause. I also greased the front wheel bearings using the little tool from riffraff diesel where you take out the speed sensor and insert grease.
View 10 RepliesTruck has just over 5000 miles on it. Had the tires road forced, no luck! Took it to the dealer ford said replace the tires 2 at a time (r then f), picked it up yesterday no better and said that ford wants to put a new driveshaft in it!
View 14 RepliesTruck is an '07 F350 Supercrew, 8ft bed, SRW, 2wd. I bought the truck last month and noticed a low frequency driveline vibration starting at about 45 mph and is noticeable to about 65 mph. Feels like a bad u-joint. So I pulled the drive shaft (two piece) and checked the joints. They seemed find so I sent it to a commercial truck shop that does driveshaft work. Had the joints replaced and the shaft rebalanced.
Re-installed drive shaft and went for a test drive. No real change in the vibration. The hangar bearing seemed fine so it wasn't changed. Doesn't feel like a wheel out of balance. My experience tells me its a drive shaft.

Highway driving and feel a stumble. Weird, then another, ok that wasn't a bump. Then steady rough idle and a heavy vibration when I lightly got back up to speed to get myself home.
Had new filters so started there. Just changed in the spring here and they were in pretty new condition but swapped them out anyway. Stripping the cap, 120 bucks and had to put a new one on.
Start truck and still rough idle, test drive and still a bad vibration.
SO, I read and search. Scanning with Ford or AE are my number one priorities and they were done along with Fuel pressure check.
Scan revieled Inj 6 out, fuel pressure at 60 PSI. We pulled plugs off injectors with results except 6, confirming it's not working.
Ordered an injector and the Aliant Power rebuild kits to freshen up the other 7.
Disassembled all 7, NO stiction problems at all and all 7 spool valves were clean as a whistle. Bodies of injectors were good on 6 of them and had a screen in cyl 3 what was completely gone (the 3 screens around the body of the injector). Tip was also plugged but one hole. (used brake cleaner in tip and air to confirm 6 holes were clear) Used the body of the core on that injector but not the spool part. Replaced all O-Rings incl the seal inside the top where rail snaps into. Sanded spools (800grit 2-3 turns) and installed same way they came out. Stem pipes and dummies new as well.
Reassemble, carefully and fire truck. WOW....running abit rough but smoother. Ive read it takes abit to get air out of system and to expect longer cranks ect. Shut it down. INspect for leaks. Button up the ficm, and few other things. Re-fire truck with abit longer of a crank. Fires and running smooth. HERE's where it starts acting up again. I can feel a small stumble....then another....then full time again. Exact same as before. Pull 6 off and it's that injector again.
Here's the big mistake I made. Reinstalling injectors, I put the new one in #4 spot and number 4 in 6's spot. Not smart, I know.
Pulling inj plugs off around entire motor while running and def No 6.
Put things away, call buddy and he says possible FICM. or harness.
So i pull inj harness and OHM every single pin and map it. 100%, I go grab his "good" ficm and test with that. HOLY COW, FOUND IT. Started great... Then as she warmed up ICP at650ish, EOT ECT getting to 100-110F (only a 4-5* delta always monitor) is starts to vibrate and run rough again.
Read some more....OHM testing is one thing, actually load testing harness confirms if it's actually no good. Harness is 450 bucks plus our lovely 13% tax so I want to diligently cross this bridge. Grab a harness off a running 6.0 and test next day.
Fires up and runs smooth. Then, as temps come up it starts again. Walked away last night and when I fired up this morning. Started great and as she warmed up vibration was back. Along with a intermittent squeak from the turbo housing area.
Codes.... SCT X4 tuner is reading nothing DTC's and hasn't since day one so I "assumed" no codes until buddy scanned with AE and since it's last WiFi update wouldn't connect to computer and gives me error code 10007 when I try to tune. **Ended up fixing last night, went into another "Tune revision update" and now connects to my computer AND returned my truck to STOCK and resested truck. Still running rough.
So I plug my PHP FICM tuner and get codes:
P1102 "Unkknown" (reading here I had my AFE off and not plugged in)
P0113 Intake air HI input
P0284 Cyl 8 cont/bal Fault
P0603 Internal control Module KAM error
P0611 FICM Perf (58v swamps, I've read always throws this code and I've had that code since day 1)
P0676 Glow #6 fail
Lastly I'll add, no smoke out tail pipe at all during all testing minus the black puff when tune loaded.
