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.
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 11 RepliesI 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.
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.
I have a quick question. I am gonna change the fluid in my 01 f250 rear end. it has 410 gears and a limited slip diff. if i use full synthetic gear oil do i have to add the limited slip additive or just the 75w-140 full synthetic gear oil.
View 14 RepliesLooking for a breakdown for installing a new clutch pack in the rear differential of my 06 F250 Diesel sterling 10.5. I found a kit on rockauto.com but it has 4 weird looking shim things I don't recognize, I rebuilt my diff in my 03 crown vic 8.8 but there's some extra pieces in this kit I don't recall.

View 6 RepliesFor 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.
View 14 RepliesFinally 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!
View 14 Replieswe'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?
My 2013 f-250 with 6500mi. has peeling paint on the front differential and the axle.. I sprayed it with some fluid film for now.

I got home today opened my door and got snaked in the face with the smell of brakes. I got out of the truck then I heard the drivers side rear brakes popping as they are cooling down. I reached down to touched the wheel and it's crazy hot. Opened the garage and went to retrieve the infared thermometer. The rotor/caliper was 350 degrees, hub was 150 degrees, axle tube was 90 degrees.
I took the wheel off and inspected stuff. The rotors do have some heat spots, the caliper visibly looks okay but not 100%. The pads look like even wear. I am guessing that the caliper either is hanging up or I have a wheel bearing going? The passenger side was like 80 degrees on everything. There is a slight shimmy while driving which to me feels to me like the beginning of warped rotors. I don't hear anything to me that screams wheel bearing noise wise.Brakes or bearings?
So i have a weird smell from the rear end, and ive had it for like 2 months. when it first happened it was a sticking caliper so i replaced that, the passenger side. the passenger side wheel would get really hot but now there isnt heat on either side, it does smell stronger on the passenger side however. i wouldnt call this a burning smell, and to tell you the truth i have no clue what the smell is related to. maybe a burning rubber smell would be the closest i could put it at, if only i could transmit smells on the internet. im thinking it has something to do with the rear diff fluid, as when i checked it last it was really old nasty and gunky, it probably hasnt been changed in a long time before i got the truck. so i topped it off and decided i would drain the diff this weekend because i didnt have time last weekend.
View 13 RepliesI have a 2008 F-450 with the King Ranch interior. Every time I hit a bump in the road, I hear a squeak in the back. It sounds like it coming from the pillar behind the door, but I can't seem to find anything that is loose or would cause this noise. I hear nothing when the window is open (from outside the cab), so I don't think it is a body mount or anything.
I've seen posts on this saying it is the back seat and I've completely taken mine out and checked every bolt and made sure it isn't rubbing on anything.
This is the 3rd crew cab truck i've had and my 2005 made the same sound, though not as frequently. My 99 also made the same sound, again not as frequent as this truck. This truck does it all the time when empty, but seems to do it a little less when loaded down, probably because the suspension is absorbing more of the bump. I can't believe this is isolated to my trucks and I am wondering to identify this noise.
My rear end cover has been leaking and I don't have time to fix it right now. I was going to check the oil and maybe add some if needed but I cant find anywhere to ad oil or check it? Am I missing something? The add plug is the one Id like to find.
View 2 RepliesWhen I am driving and hit a bump in the road, especially when the rear tires contact it square. I hear a clunk at the rear end. Sounds like suspension, loose tailgate...
My truck is a 2016 F250 Crew Cab Short Bed. It has a factory installed fifth wheel hitch. I have looked at the obvious, spare tire, loose bolts... I removed the tailgate and it still makes the sound. I removed the insert in the receiver, still makes the sound. No goose neck ball in fifth wheel hitch. Checked bed bolts. Cant find it. Drives me crazy.
I also have a 2008, exact same truck, 200,000 miles, no clunking. I have driven in my friends 2014 F350 Crew Cab Long Bed, it clunks. Dealer pulled a new truck off the lot today, took a drive, it clunks. Dealer can't find it and confirms there is a clunk.
The last couple of weeks a new clunk has appeared on my F350, 6.2 CC LB FX4. If I've been parked for a while, when I drive off, within the first 30 yards or so there's a clunk. Seems worse when I've turned sharply out of a parking spot. Sounds like the rear diff or drivetrain... I have a locking rear diff. Is this engaged or disengaged while "at rest"? Could it be that its slow to unlock when I start?
View 13 RepliesI have a 99 SD 250 diesel, I also have a broken rear leaf spring. My truck has a 3 1/2 in. block between axle and leaf. My question is this. Can I remove the block and install 4" lift leaf springs without messing up my pinion angle? The blocks look square. But someone toldme once they are made to a specific angle for rotating pinion for better u joint alignment. Sounds like it could be true.
