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.

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.

I just purchased a F250 Gasser with the 6.2. I made sure to get it with the 4.30 rear to babl to tow a little better when i upsize the tires a little. Where I can find the drive output ratio from the transmission?

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.

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?

I had a new engine put into my 2006 F350 SD 5.4 last year and ever since then I can't keep the freon charged in my ac. The mechanic said all he did was lay the compressor out of the way and didn't disconnect anything ac related. I have 2 different shops keep my truck for a couple days and neither could find a leak. Yet a month later, freon is low. I think I have more dye in my system than freon.
I put 2 of those ac leak sealers, the ones you have to ask for behind the counter and can keep my ac working for maybe 45 days, then throw 3 cans in it. No dye is showing up nor will the sniffer find anything. I hate to go to the dealer because I figure they will want to replace everything. Any tips other than try another shop and maybe they can find the leak.
Ford Super Duty (1999-2016) :: 2001 F350 V10 - Hard To Find Gear
Got an '01 f350 v10, auto. When using steering column shifter tends to be hard to find reverse and drive. Is it something in steering column selector or is it in tranny? The truck has 40,000 miles on it. Have a parts truck also so just trying to figure out where to start first.

I plan to be buying a 2000 F250 V10 in a couple of hours.
I had my boss run by and take a picture of the door tag so I could determine the axle code. What he sent me was this:
Other than giving me the knowledge of how bad of a photographer he is, it doesn't tell me much else. The axle code area is blank, what gives? Am I just going to have to crawl under the truck when I get there after work?
Ford Super Duty (1999-2016) :: 2015 - Front Axle Leaking A Lot?
I have a 2015 F250, cc 4X4 PSD. It has 22,000 miles on it. I notice a small quarter sized drop of oil after it is parked by the right side front wheel. It is coming from behind the dust cover and universal joint where the axle goes into the tube. I dont know how long it has been leaking. My issue is I am about 800 miles from home on a camping trip, have to go back to work Monday, and lcoal dealer here can't take it in till next week. So, if the hubs are not locked and the truck is in 2 wheel drive, the gears shouldn't be turning right? I assume it is ok to drive home. I didn't want to pull the plug and check the fluid because if any runs out and leaves a stain on the cover, I don't want ford trying to deny warranty claiming I messed with it first.

Check out the pics. 99 f250 4x4. I have a leak in my front axle shaft. It looks like it is coming out of the dust cap on the end of the front shaft. I am pretty sure it is differential fluid from the smell. Is there a seal before the dust cap? Is the shaft hollow with fluid in it? I thought it was just in the differential and if it leaks it is at the seals where the axle goes into the differential not at the otter end.

I have a slight problem and don't know how serious it is. I own a 2003 F350 with a lift kit. After my drive shaft shattered last September. due to a U-Joint a clicking noise started up in the front axle area after we locked the hubs so we could crawl it down the road out of traffic.
What would be the likely causes and how much would a typical repair/replace cost?
Ford Super Duty (1999-2016) :: Front 4x4 Axle Still Turn When Unlocked
I am not up on the exact operation of the hub lock/unlock on superdutys but when following them, I can see the front axles still turning with the wheel. So even with them "disengaged" they still turn with the wheels?
If that is the way they are designed to do, why? Seems like efficiency could be gained by having them actually disengaged when not needed. And save wear on the inner housing seals.
Ford Super Duty (1999-2016) :: 2004 FX4 - Rear Axle Locks Up?
It seems that every time I put the truck into 4 low, the rear axle locks up. When turning, one tire skips no difference which way I turn. When doing this, I do not have the front hubs locked. Also noticed that when turning in 2wd one tire will spin w/o other locking up. I have spun the tire enough for the L/S to catch, but hasn't. I have heard that the locker was not available until years later. Is this true?

I noticed the other day after my truck was parked on a bit of a angle there was diff oil from the passenger side on the ground. reading a bit on here i learned the axle seals are way in the front housing close to the front diff. and yesterday driving a heavy load around my front brake driver side got stuck on a bit and over heated and was smoking, couldn't even touch the rim it was so hot. anyway about this axle seal i got the hub off right now but cant seem to pull out the axle assembly through the knuckle but i see i have to pry and most likely wreck that seal. Looking for a link of piuctures or how to replace the axle seals in the housing.

Love my '11 f250 SD 4WD CC SB. 6.2 with 3.73 e-locker. I've got 5 Star tunes in it, and the truck is a joy to drive empty, and tows my current 7k camper fine, though on steep inclines I wish I had the 4:30 gears.
Well, we just bought a bigger trailer, dry weight is an addtl 2400+ at 9400, so I'll need to do something.
I don't want a different truck, don't want (another trouble-prone) diesel. I think with 4:30s and the tune, I should be fine towing that trailer (with gear and passengers, probably 11-11.5k loaded). Not doing mountains here, just Michigan hills.
What's the best way to "do" a gear swap? I know if I buy a set of gears and a shop screws Em up, it's gonna whine/hum and still cost 2k to do (truck is 4wd)
I'm up in the boonies and finding a shop to swap the gears will be a problem. Getting Em done right will be even MORE trouble.
Can I just find 4:30 axles ans have them swapped (anything in t-case or sensors need to be touched?). I don't care if I lose the e-locker, I never use it.
Ford Super Duty (1999-2016) :: 2006 - How To Tighten Front Axle
It's the Right Front Axle Shaft on my 2006 F250 where it goes into the Hub/Bearing assembly.
Seems way to loose to me but after I removed the Lock-Out, I discovered the Axle Shaft is held in by a Snap-Ring not a Nut (WTF) so how do I get this tightened up
Also it's my understanding (I didn't remove) between the Axle & Steering Knuckle there's a rubber O-Ring. Could all this play be from that O-Ring being wasted Although that doesn't seem likely to me, Iam worried what's wrong
