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.

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?

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) :: Tire Air Pressure Differential Front / Rear
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 decided to go ahead and do a rear block replacement. I'm going to install the Ready lift 4 inch blocks.
I have both u bolts and nuts off of both sides. Rear stabilizer bar disconnected and both shocks disconnected. However, when I raise the rear of the truck, the axle raises as well. What could be holding it on still? I noticed there's a nut in the middle of the leaf springs. Do I take that nut off? I just don't know what could be keeping it from separating.
Ford Super Duty (1999-2016) :: 2003 F250 4x4 - Left Rear Caliper Sticking After Replacing
Two weeks ago did a road trip to NH from RI and i heard a slight dragging only at low speed (10-15mph) in my left rear tire. figured the caliber was dragging a little, it was. Before arriving in NH the brake light came on. Long story short i get back to RI and the left side noise gets worse and starts to lock up. I finally replace the rotor which was warped, pads, and caliper which was bad.
Was driving it same day and still here the same dragging and screeching noise and the brake light is still on. On my way home the left side locked up at low speed without hitting breaks and slid the truck, mid you all parts are new on that side. I am not sure what it could be at this point something in side the axle?
Ford Super Duty (1999-2016) :: Rear End Chatter In Reverse - Damage In Gear Head?
Ok, I've seen a post or two about this issue of rear end chatter on the super duty But not that many so I am going to ask a question here and now......what causes/allows this to happen and what purpose does it serve? also, does it cause any damage to the gear head? or any other part of the rear end?
My truck tends to do this from time to time when I am plowing snow (only when backing up, or at least so far) and I really can't relate it to condition other than maybe the fact that pushing snow may cause the gear oil to get hotter than normal driving and thins out and causes this?

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!
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?

And by the quick look without much digging in appears as though I have to take the DEF tank out or significantly loosen it to get at them. I'm no neophyte when it comes to this stuff and will take the DEF tank out of necessity, was just wondering.
