Front and rear differential models
Probably been answered a 1000 times but what is in my 05 PSD f250? Dana 44 up front and Ford 10.25" rear? Seriously thinking about a 4.10 gear and need to know what I need as to whats available.

This might not help much but....
The Excursion is a Dana 50 up front and the Sterling/Ford 10.25 (I believe) in the rear. there was some discussion on the Ex forum about the SD and the Ex not having the same front axle for 05' but don't quote me on that. Not sure if it helps any but that is what the Ex has...

Ryan,
Since at least 03 the front axle on an F250 is a Dana 60 (35 spline, 1.47" spline diameter, 9.75" ring gear), rear axle is a Sterling 10.5" (35 spline, 1.50" spline diameter, 10.5" ring gear).
Hope this helps

Thanks Blackhat, I downloaded the pictures of the differential covers from one site and the 44 and 60 are real similar, as are the 10.25 and 10.5 rear. 4.11 is available for both. Now to see if it is cost effective, as I don't have to pay for my fuel, even when not working, just would love to be able to get 10 mpg towing my toy hauler. I would think it would reduce strain on the engine/trans/transfercase tremendously, and also help to conserve some fuel while getting the truck rolling with less effort, which is where mileage seems to suffer the worst. I as I feel others would as well give a little on the highway mileage to get some back towing. 15-16 highway would be fine if I was getting 11-12 towing.
Has anyone done this on an F250 yet? I know what some have been reporting on the F350 dually with the tow boss package and the dually with the 4.10, but I know those trucks are a bit heavier. So probably not a fair compairson.

Are you doing the install yourself Ryan or do you know somebody with experience? I sure wish I knew how to install gears myself, that's a big cost savings. Try these for comparison to Randy's:

Russ, most likely I will do the install myself. I feel very confident in my abilitiy even having never installed a ring and pinion. I have however installed numerous blowers and oil pumps that require checking the pre-load and back lash of precision gears. I do know someone who I used to work with that has set up numerous circle track differentials. So if I get into a bind, I'll call him.

Sounds like you have the right experience for the task. Most of the gear vendors also have Tech-lines if you have questions, but it's great to have a friend with in-depth knowledge.
It's just amazing to me how diff lube can stink so badly for so long.... laying on cold concrete makes it worse.
Let us know what you purchase and how it works out for you Ryan.

The number one thing to remember when mating 2 gears is the contact pattern. Yes the preload is important as well as the crush, and backlash, but as simple as it sounds nothing more than a good dial indicator and prussian blue is needed to check backlash and contact pattern. Depending when this all comes together, (may be after the first of the year when I get my bonus and tax return back) I will take pictures and do a write-up on it.
Yes gear oil has a smell all its own, much like a skunk.
