Ford Super Duty (1999-2016) :: 2002 - Dana 80 Rear Diff Ratio Change - Adjusting Speedometer Readings?


Nov 4, 2013

I have a 2002 F450 2WD AT with the common Dana 80 4.88:1 posi rear diff. If I change the ring & pinion to 4:10 do I need to change the carrier or does my current carrier fit 4:10 & lower [4.63,4.88, 5.13 etc]? Will I need to adjust my speedo readings & if so how is this accomplished? Electronically via the diagnostic port?

Ford Super Duty (1999-2016) :: 2009 F250 - Rear Diff Fluid Change / Pinion Seal Leaking

I just picked up an 09 F250 a couple of weeks ago and I was planning on replacing all the fluids since I'm not sure when everything had been done in the past, but it did pull a camper 5th wheel. It has about 93000 Km/57000mi on it

One thing I noticed when reading the manual is that a rear diff fluid change is not necessary on these rear axles unless they have been submerged in water or repaired etc..

Just after I got it I noticed the pinion seal was leaking. It was fixed under warranty but the dealer did not replace the diff fluid as they said Ford will not pay for it.

My question is do you think I need to replace the diff fluid or should it still be good, given the relatively low mileage.

Ford Super Duty (1999-2016) :: 2008 F250 - Changing Rear Axle Ratio - Lower RPM?

My truck is a 2008 F250 6.4 Powerstroke 4x4 King Ranch, CrewCab, Shortbed.

I don't know which rear axle ratio it has - maybe someone can help me. the tires mounted are 275/60R17 and in fifth gear (TC locked) the engine has 2000rpm @ 70mph. I think it is a bit to much so I want to install a kit with and lower ratio. I pull trailers just sometimes and here in germany these only have 3,5tons max weight. So I think I don't need this power at 70mph. 1750rpm would be enough. How do I have to modify the front axle ratio if I get a lower-ratio-rear-axle?

I want to lower the fuel consumption. After some modifications, the truck needs round about 12-13L/100km (18-20mpg) and I think it is possible to lower this as bit.

Ford Super Duty (1999-2016) :: 2002 F350 - No Power / Speedometer And Tachometer Swinging Back And Forth

I have a 2002 F-350 with a 7.3 powerstroke. Last week, I replaced both my batteries. When I tried to start the truck, the electronics when a bit crazy. Speedometer and Tachometer swinging back and forth. Then when it did start it ran rough and after a minute it shut off. All electrical functions are completely dead. I finally unhooked the batteries and went in the house to cool off. When I came back, rehooked up the batteries, it started right up and everything acted normal. Everything was normal until last night, it started fine and was idling for about 5 minutes and it shut off. Absolutely, NO electrical power, even tried to jump start and still no electrical activity. Unhooked the batteries waited about 15 minutes, hooked them back up. It started just fine.

Ford Super Duty (1999-2016) :: 3.73 VS 4.30 Axle Ratio?

Just ordered a 2014 SD 250 FX4 CC SB 6.2L Lariat. I ordered it w/ the 3.73 axle ratio, but have two weeks to change it if I choose. Was wondering the pros and cons of both axle ratios. Going to be hauling a 16 foot tandem axle enclosed trailer with 7 dozen goose decoys and a four wheeler and other gear through corn fields 100 days a year. I'm fairly hard on trucks and this is my first ford I've owned myself, but have driven a lot of them at work. Basically need opinions on best axle ratio to get in and out of muddy, or snow covered fields.

Ford Super Duty (1999-2016) :: Locking The Diff - Clunk When Turned On / Off

When I turned it on for a second, last winter, I rem hearing a clunk, and then another clunk when I turned it off. Made sense to me.. So, I figured I'd just activate it again now, and roll up and down the driveway once to exercise it. BUT, when I turned it on this time, the light came on, but no clunk when it came on, or off. I went up and down the driveway anyway, and I THINK it felt like it was ON, but I didn't make any turns, because I figured that would be bad.

Any one that is silent when it locks? I think I saw a post where everyone said it's supposed to clunk on/off. Could it just be the season/temps, only clunks in winter? I have a 4x2 btw, so it's just a turn switch. I hope it's not stuck or frozen somehow already..

Ford Super Duty (1999-2016) :: 2013 - Getting Gear Ratio Closer To 3.73 For Fuel Economy?

I have a 2013 F450 Platinum and I love it. I would really like to get my gear ratio closer to 3.73 for fuel economy. Have not been able to find replacement ring and pinions to go to 3.73, so my only other option is to do it through changing tire size. I have 4.30 gears and based on what I have found, 37 inch tires will get me really close to the 3.73 ratio. I want to keep my truck as close to factory as possible, but I do want to do a leveling kit.

So can I fit 35x12.50x17 Toyo MT under my truck with just a leveling kit and use the stock rims? If not, what are my other options?

I have seen the option to swap to 22" shaved Alcoa's, but don't really want to go through all of the spacer/adapter stuff.

Ford Super Duty (1999-2016) :: Oil Change Soon Warning And Oil Change Required Message

Circumstances required me to make an emergency trip to Phoenix this week. On the way down, I first got the "Oil change soon" warning, followed by the "Oil change required" message a few hundred miles later.

I religiously keep my truck serviced on time, and have never had either of these warnings come up before. My truck had 2700 miles on it since last service was done when this first warning came up. My truck gets very little idle time, so it's not sitting idling for hours a day.

My question is, is this oil change message a result of an actual oil monitoring sensor that measures oil quality on-the-fly, or is it strictly based on a miles or odometer timer that gets reset when dealer changes the oil?

At this point I'm wondering if the kid that serviced my truck either forgot to reset a timer, or worse, just "pencil whipped" my oil change. I have to call my home dealer back, since the service manager wasn't in yet when I called.

Ford Super Duty (1999-2016) :: 2002 - Rear Brake Hanging Up?

I keep having this problem with my 02 Superduty. The rear brakes keep locking up and smoke the pads. The truck is not driven much so that is most of the issues. it has less than 63,000 miles on it. Mostly only driven in the winter with the salt and crud so rust is a problem. What is your advice on changing so that I can get more than a year without having to do it all over again. I am going to get new calipers and the brake kit. Should I get e-brake stuff too?

Ford Super Duty (1999-2016) :: 2002 F250 V10 - Oil Leaking From The Rear Of Pan

If you look at the top of the picture you can see the two bolts with fresh oil on them.

I have a 2002 Ford F250 V10 Pick up. I noticed oil leaking from under the oil pan. I wiped off the pan and bolts to see where it was coming from. The oil seems to be leaking from the rear of pan. There's always fresh oil on the rear bolts that hold the pan and I also noticed oil coming from one of the two hoses that go from the radiator to where the oil filter mounts.

But don't those hoses carry radiator fluid and not oil? I bought this truck in July and no oil leaking from underneath. It seemed to have started after I did my first oil change on it. I used regular Vavoline 5W-20 and motorcraft oil filter.

Ford Super Duty (1999-2016) :: 2002 F350 5.4L - No Brake Or Rear Running Lights

2002 f350 5.4L

No rear running lights or brake lights
No third brake lights
Headlights work
No signals or hazard.

I have power to the multifunction switch when I use a jumper wire to bypass the switch I can make the lights come on depending on which slot I put it in. I replaced the multifunction switch twice just to see if I got a new bad one the first time, but to no avail. I cant run my truck a night without the lights.

Ford Super Duty (1999-2016) :: Speedometer Won't Working?

I just bought a 99 f250 sd 5.4. The speedometer doesn't start working until it reaches about 30 mph. The transmission doesn't shift correctly until the speedometer starts working. I cleaned the speed sensor on the rear end but that didn't work. I don't see any sensors or switches on the tranny other than the neutral safety switch. What it is?

Ford Super Duty (1999-2016) :: Speedometer Stops At 54 Mph

On my '99 F250 PSD 4x4 the speedometer climbs very smoothly (normal) until I hit 54mph and then it just stops going up. Reviewing other posts I have changed the DSS (differential speed/ABS sensor) and the VSS (tranny speed sensor). Disconnected both batteries for several hours to see if it would clear.

Doesn't bounce, peg, go to 0, just won't go past 54mph. No power loss. Tach continues to climb and speed continues to increase. No strange symptoms except this 54mph thing. It is completely repeatable. All fuses under the dash and hood check out ok.
