I recently changed the rear diff fluid on my 1999 F250 Super Duty (180k) It was due plus I was getting some chattering when making turns from a stop. The Diff fluid had about 60k miles on it and seemed to be a little low even though I don't see any leaks. I paid to have it done last time so I can't say what kind of a job they did.
I used Motorcraft diff fluid and 8oz of friction modifier. Two weeks later and about 500 miles, today I noticed on two occasions when turning a moaning sound coming from the rear of the truck. Could this be a sign of too much friction modifier and the cluthes are slipping or is something else going on?

So I am having yet another problem with my 2015 f-350 .... We did not receive any warnings that the DEF was empty until MPH was limited.
2 1/2 gallons was added to the tank less than 1,500 miles ago.
Heat problem many have been solved but will not know until winter, see this link [URL] ....
Because of the unreliability and unpredictability of the truck we are now filing for lemon law under NY state law.
Ford Super Duty (1999-2016) :: Rear Differential Tag
I was trying to determine how to read the metal tag on my rear differential in an attempt to figure out what rear gear I have.
The plate reads: "3 V 414 F" on the top line and "731053L03" on the bottom line.
It's a 2004 Super Duty 4x4 Crew Cab XLT with the 5.4 gas.
Ford Super Duty (1999-2016) :: Mystery Slip / Low Power During Tow
I've got an issue...
Symptoms:
1. Sudden slip feeling(like you just hit a small patch of black ice while powering up a hill.)
2. Turbo Pressure still spun up.(According to gauge)
3. Backfiring out of the airbox. (Sounds like a flat tire)
4. Lose a bunch of power. (Feels like a car running on 6 out of 8 cylinders)
Only happens at mid-throttle, during a long uphill run while towing. Doesn't happen when not towing or first thing out of gate when engine is cool. No problems going downhill either.
Situation: Towing a 10k pound 5'er, to Yosemite, I would get this random sudden lose of power, that accompanies a series of backfires out of the airbox during a long steady uphill drive.
Truck has 161k miles on it. Fluids are all brand new. I didn't see any smoke coming from the tail pipe, like turbo was done and letting oil into the engine. Oh also, no check engine lights.
Ford Super Duty (1999-2016) :: Rear Differential Leaking
The rear differential is leaking on my 2000 f350, i am going to replace the gasket. When I take the cover off will all the gears pop out or are they held in? Also how much differential fluid does it take?
View 8 RepliesFord Super Duty (1999-2016) :: Transmission Slip In 1st Gear And Reverse?
Drove the wife to work this morning. The turn off into town there was a lady stuck so I pulled over in the drifts. After putting in back in gear I had to get on it to get out of the drifts. Snow was blowing over the windshield, and I imagine throughout the engine bay.
After that it felt like it stayed in 2/3rd gear. I'd hit the pedal and it would redline and sort of accelerate jumping in and out of gears. So i slowed down to a stop. Accelerated slow and it was ok but when I got more on the pedal it would feel like it was slipping. Once I got in the driveway, she idled for about 15 mins while I shoveled out my spot. Once putting in gear again I had to rev it up for it to move.
Also reverse, had to rev it up to move it.
Ford Super Duty (1999-2016) :: 2001 - Slip In Automatic Transmission
A few weeks ago I noticed what seemed like a "slip" in my automatic transmission. Only happened a couple of times and I thought maybe it was just me imagining it or I didn't have the shift selector lever firmly in "D"rive. Then I went on a 4,000 mile trip pulling about 3,500 lbs. on mostly flat roads but it did include some 7% grades in the hilly parts... the truck performed flawlessly.
This is probably not related but ... after I got home, the truck sat for a few days and then I noticed a coolant puddle under the truck. Traced it down to what appeared to be a slow drip from a bad squeeze clamp on the large, lower rad hose connection. Replaced the squeeze clamp with 2 worm drive clamps and no leaking issue since.
Then last night, the tranny seemed to "slip". My short run across town started out OK. However, when I arrived at my destination, the diesel motor would rev to around 2500 rpm but the truck barely moved forward. It eventually did shift into second but also with high revs. It was the same feeling as if it were a manual tranny and you were giving it lots of throttle but only letting out the clutch a little bit (i.e. riding the clutch). This happened a couple of times last night. Also at a stoplight with the brakes on firmly, the truck was gently and rhythmically "rocking forward" as if the tranny was not fully disengaged.
When I worked through the gears shifting manually, the problem seemed to disappear and the truck responded going through the gears normally. Upon restart about an hour later, tranny shifted fine both in the city and at highways speeds on the way home.
B-I-L commented "sounds like your clutch is slipping". Not exactly sure what he meant as I had to leave. I'm hoping this will be a simple fix/adjustment and not the dreaded mechanical diode failure leading to a replacement tranny. Truck only has about 75,000 miles on it.
I'm suppose to head out on my annual vacation next week carrying a 3,500 lbs. truck camper and pulling a 3,000 lbs. cargo trailer with our gear. Obviously if the truck is sick, this trip can't happen. I know some of you would dive right in and start taking the tranny apart to repair it ... What is wrong with my transmission and what I should be doing next?

View 11 RepliesFord Super Duty (1999-2016) :: 2004 F250 - Rear Differential Going Bad?
I have a (new to me about 40 days ago) 2004 F250 SD Lariat Crew Cab 4x4 6.0 diesel. 137,xxx miles.
I thought Id gotten a good "deal" on this truck when Id bought it however the last 40 days have been very expensive. The "stealership" I bought the truck from was on a 35mph rd and I couldn't test drive it at highway speeds. So I bought the thing "knowing" there were a few "minor" sniggles wrong... however once about 15 miles from the dealership/stealership and on a highway, the real fun began.
I had a terrible shake, shimmy and groan/whine at speed no matter if the truck was in gear or not.
Since that time ive repaired/replaced:
1) Both front hubs/bearings
2) Both front hub locks
3) Both front brakes and calipers
4) 4 New Hankook tires
5) Ford Dealership Diesel engine service/lube (essentially an expensive oil change)
6) Ford Dealership transmission service
7) Drained (with a siphon) and refilled the rear differential + OEM Ford friction mod.
Ive eliminated problem after problem after problem with this thing.... and yes, the truck does get better with each repair HOWEVER.... Ive still had this groan/whine from the rear end of the truck and a rumble from starting at a dead stop despite my changing out the gear oil in the rear diff.
So I take it today to a local shop (that I trust/sort of) for a 2nd opinion. Their technician takes the truck out for a test run and comes back in 10 min saying he has no clue but the sound was annoying and he'd need to put it on a lift if I could wait.
I saw the truck go up... a few parts get wiggled, some head scratching, saw the truck go down, watched another tech jump in and 2 techs run it out for a test drive.
When it came back, I watched the truck go up again on the lift... this time however they just lifted the rear and with one guy in a pit the other revved the motor. I watched as the wheels spun. A few minutes later both techs came in and said my "rear differential was shot".
They pulled the diff mag plug which was caked in metal deposits. It looked the same when I pulled it off the first time and did the fluid change (yes i cleaned off the plug before putting it back). I had seen differentials (in the past) have deposits like that before on plugs but the units were still good and such deposits were considered casualty of wear and tear.
However im being told the rear end is shot.. When I inquired about just replacing the internals of the diff, it was a simple bolt in/bolt out job.
Ford Super Duty (1999-2016) :: Bad Grinding Noise From Front Driveshaft / Differential
For starters I have a 1999 F-250 5.4l changed all 4 ball joints about 15,000 miles ago. I have been hearing a grinding noise coming from the front end for the last month only when I turn left and at slow speeds. I was servicing the TC so I threw it in 4 wheel to check it and it wouldn't engage until I started moving. When it did engage it was a bad grinding/ clunking sound coming from maybe the differential.

Finally finishing up my 2001 F250SD 4X4 project. Decided to pull down the front axle to replace the dust seals. I've got everything apart including the large knuckle seals. Tried to pull the passenger side axle out but it only moves about an inch to an inch and a half before it stops. Took off the differential cover to look for damage or something obvious but I don't see anything wrong. The axle is moving within the splines of the spider gear but that's it. Stumped and sitting on jacks!

Wondering what difference in tire pressure are you running front to rear. I have a 1999 CC LB 4x4 with a v10 with 180k on it and have always had to run lower on the rear with a empty bed. Most of the time I'm empty. If I don't the rear centers wear a lot quicker.
I ran KO's most of those miles and recently switch to Geolanders. The tires are 315x75x16. BTW the geolanders are doing great. A better rain tire, smoother and much more quiet. 6k on them so far and very little wear. Time will tell, I would get 55-60k out of the KO's.
Ford Super Duty (1999-2016) :: 2000 F250 Transmission Is Starting To Slip Occasionally
I have a new to me 2000 F250 7.3 diesel with automatic. Truck has 185K miles and tranny is starting to slip occasionally. Do these trucks come with a OEM tranny cooler or do I need to add or upgrade the OEM one. Someone also told that there is something called "bulletproofing" the tranny on these trucks. BTW, what would be a reasonable cost to have a two wheel drive auto tranny done on my truck?

I have a 2002 7.3 with the 4r100 173k miles. If your nice to it she drives fine, but if you get on it the torque converter will slip/stall kinda revs up like 300 rpm then slams really hard between 1st and 2nd. Other gears work fine. I've only had it not happen like 10 times since I've owned the truck ..... I don't really beat on it except for towing which I'm starting to do a lot of. Wondering if putting a new stock torque converter in it is worth it.? Not gona blow the bank on a TC unless I'm putting a brand new trans in the truck. Which I don't think it needs in the near future.

View 14 RepliesFord Super Duty (1999-2016) :: Squeaking Noise Coming From Front Differential Pinion
we've had a bunch of snow this week and I've been driving around with my hubs locked in. today I noticed when I was slowing down to pull into my driveway I could hear a slight squeaking sound(sounded like a squeaky belt) coming from the front.
I verified it was coming from underneath the truck behind the engine compartment so I unlocked the hubs and went for a drive, the sound was gone. I crawled underneath and turned the front driveshaft by hand and I could hear a slight rubbing sound at the back of the pinion. The bearing doesn't have any play in and there are no leaks. What is going on? Could the bearing be starting to fail or could the rubber seal around the pinion have some grit in it causing the noise?
