Ford Super Duty (1999-2016) :: Tire Air Pressure Differential Front / Rear
May 21, 2015
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 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.

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.

2014 f250 - tires call for 75 fronts, 80 rears. I have been running 60 in all four corners for 6 of the 7 months I have owned the truck. Just turned 8000 miles and yesterday morning the low tire pressure light came on. Checked tires and all good. What might be happening?

Went to leave for work this morning & got a "low tire pressure" warning...checked at work (isn't it always the last tire you check?), going to have to keep an eye on the left rear..was down to 45
with all the money we spend on these rigs, why can't put in a tpms system that would allow us to see WHICH tire is low?
Any aftermarket system that allows monitoring of INDIVIDUAL pressure? (ultimately, it'd be nice to get a 4 axle system that would "communicate" with the trucks (very basic) system, but also allow monitoring of my RV axles as well)

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.

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?

Ok, so I got this new Superduty that requires 80 psi in the rear tires and 70 psi in the front for 17" tires. What psi are you guys with similar vehicles using when driving around unloaded?

How to shut off the Low Tire Pressure message? My tires are at 65-70 pounds and the message still shows up at every start up.

I just bought a 05 F-250 156" wheel base crew cab 6.0 with LT305/70R17 Nitto Terra Grapplers. What will be the tire pressure. Manufacture label on truck says 75psi cold but the tire itself says 65psi max. I mostly drive without a load also.

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.

What is the proper tire pressure for these trucks (F250)?
Sidewall says max is 80 PSI.
Door jam says 71 PSI.
This is coming from a guy who has traditionally driven passenger cars and trucks. I've never even gotten CLOSE to advertised max PSI ratings. 71 seems awful close to max PSI.

Every time I put the headlights on or just the running lights within 15 minutes it trips the tire low pressure warning, how can the 2 be connected? Turn the light switch off and anywhere from 5 to 20 minutes the warning low pressure light turns off. I know take it to Ford but I'm out of State presently and l'll just wait till I get back home next month.

So we had a subzero weather week last week and on one of the below zero days by low tire pressure light goes on - on my dash. I've checked all 4 tires and they are not low. Do I have a bad sensor? Or is the cold causing this?

I have a 2010 F250 Super Duty with 18" factory wheels. I started having intermittent Tire Pressure Monitor Faults. My research lead me to believe that the seven year old sensors were probably running out of battery life. So... When I had new tires installed I also had new FoMoCo sensors installed and I purchased a FoMoCo tool (TPMS 19) to train the new sensors. My problem is that I cannot get the sensor training process to work. When I put the truck into the train mode and try to retrain the LF tire, nothing happens and eventfully the horn beeps twice and the dash reads that the training failed. Where is the receiver that the sensors communicate with? Could it be bad?

Got a 'Tire Pressure Sensor Fault' message a few times on the way back from Florida. Tire pressures were all fine. Hate that it doesn't say which monitor has the problem. Anyway... it comes on, but after a few minutes goes back off. Saw it a total of three times over the course of 1,000 miles in two days. Is this the sensor failing and requiring replacement? Or is the system itself starting to fail? Would ESP cover this?
