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) :: 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 7 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) :: 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.

Looking 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.

my truck at 210k miles got a new radiator (seeping at seams), thermostat, water pump (bearings shot, leaking), intake manifold (The crossover was leaking). It now has 227k miles. Oil leak in rear at head gasket by starter (bad head gasket?) It overheated the other day( blowing coolant out the expansion tank needle in the red) Replaced thermostat. Drove around for two full hours, seemed fine, Drove to work today it overheated ( same thing, blowing coolant needle pegged) didn't make it to work. There are no external leaks and its not putting steam or white smoke out the exhaust. I read somewhere that a blown head gasket could make the truck overheat, is that possible? What all could cause this problem?

So I've put about 1000 miles on my 03 F250 since buying it, and just the other day it's started leaking from the rear of the passenger head gasket. Enough to drip on the driveway and exhaust, and have some exhaust smell. 126,000 miles, 5.4
I've checked with my local ford dealer, and It also needs passenger exhaust manifold and studs, so the dealer price to tack that on would be a whole lot more too since there are already a couple studs broke. It would be best to get it done when the head is pulled.
I've checked with several local mechanics, and none of them are interested in pulling the head on this engine. That has me concerned about doing it myself too..especially since it fits in my garage with only a few inches to spare..
Ford Super Duty (1999-2016) :: 6.4 Versus 6.7?
the options i am looking at are either a 2008-10 Diesel 250 or 2011' Diesel 250. It will be a weekend only truck and only towing light loads every once in a while.
My question is which motor is better? the 6.4 or 6.7?
I don't have a clue which is better, but all of my friends debated about this at my house this weekend for a few hours, so i am just looking for some info i guess.
Ford Super Duty (1999-2016) :: F-250 Versus F-350?
I currently own another brand of a one ton, SRW, diesel pick up. Use the truck to tow a 35' 5th wheel. I'm considering a new truck this spring, & it WILL be a brand change. I was looking at the tow ratings in the March towing guide in Trailer Life mag. & the 5th wheel ratings for a F- 250, & F-350 Super cab, SRW, long box Diesel are the same, 15,900lbs, with a 3:31, or a 3:55 rear. So the question is what is the difference between the 250, & 350?

I see now that you can get the wide track front axle on the F-350 as well.
Ford Super Duty (1999-2016) :: F250 - 6.0 Versus 6.4 Or 6.7?
So, currently I have a 2006 6.0 that's been bulletproofed with a 4.5" lift, 35" tires, and a few other things. I've debated going to an Ecoboost F-150, but I really don't want to give up the payload and towing capacity of the F-250.
The big gripe I have about my F-250 is dealing with diesel issues in the winter and the stiff ride and wouldn't mind a little quieter engine. Besides that I love the big truck. My question is if the 6.4 or 6.7 trucks are better about not gelling and not starting in the winter compared to the 6.0? I've read that the ride quality on the 6.4 and the 6.7 is much better than the 6.0 truck.
I've actually debated just getting a dually F-350 and getting another car to drive when I don't need the truck. I'd never have to worry about too heavy or big of a load and then wouldn't have to worry about driving a big truck into tight places either.
Ford Super Duty (1999-2016) :: F250 Versus F150?
I'm trying to decide if I need a f250 diesel or to just get another f150. I will be pulling a car trailer a couple times a year with a 78 ford f150 with a 460 in it and the rest of the time it will just be a daily driver. The problem I'm having is that the truck weights I'm guessing some where in the 5500 to 6000 lb range not really sure. I live out in Colorado so I will have to drive through the mountains pulling the truck to different mud races and don't want to have to over work the f150.

Ford Super Duty (1999-2016) :: 2001 Model F250 Versus F350?
I know on certain years the F250 and F350 really weren't any different. Same axles etc. I guess the F350's got an extra overload spring?
I am more curious than anything what separated an F250 from F350 in this year range.
Ford Super Duty (1999-2016) :: Tighter Left Turns Versus Right - Normal?
I don't do much city driving with my rig. And when I do, I head straight to the back of any parking lots I encounter. But I decided to take the ol' girl to a big empty church lot today to get a feel for its turning radius.
I found that it makes a tighter left turn vs. a right turn. And the difference is 6-8 feet. I repeated this many times. Steering wheel was fully locked in both directions.
Is this normal? Others experienced this? It drives straight and true and the alignment was given a clean bill of health not too long ago. Weird.
