Question about 2005 Ford F-150
I have a 2005 F150 4x4. I would like to change my oils in my differentials and my transfer case. Im just wondering what to use... i think its Dextron 3 in the transfer case and 80/90 gear oil in the diffs but i am unsure... does anyone know for sure? and maybe how much each takes?
I worked from the assumption that you have the 5.4L V8 since you did not specify, if this is incorrect then let me know and I'll see if anything changes.
Front Differntial - You can use 80W-90 or 75W-90 but 80W-90 is preferred. It holds just under 2 quarts.
Rear Differential - This calls for 75W-140. It holds just under three quarts for the 8.8, 9 & 9.75 Ring Gear differentials. For the 10.25 Ring Gear differential it takes 3.5 quarts.
I know on the Rear Differential there was some kind of issue with chattering using anything other than the 75-140 and I dont know if they had that cleared up for the 2005 model year or not.
Transfer Case uses Automatic Transmission fluid and I would HIGHLY recommend using a fully synthetic transmission fluid that meets the MERCON V spec at a minimum (Ford uses MERCON, GM uses Dexron). The transfer case takes two quarts to fill. But when Ive serviced these in the past, Ive used an extra quart just to pump it in and drain it out so that it flushes things through, then use the remaining two quarts to fill it up.

You are probably right, but you are correct to want to be sure.
Given the potential $$$+ down-side of getting inaccurate info, and the attendant damage possible, it really IS worth the $20-25 for a Chilton's, Haynes or other professionally produced hardcopy manual - - lots easier to refer to than a computer when you're out actually working on it with dirty hands.
Then you have it in writing, specific amounts of what you'll need, and probably a listing of any special tools you'll need half-way through the job (because that's usually when you find out if you need something you don't have).
You'll also know how much capacity you'll need to handle the waste oil before maxing out your container and spilling the excess all over the garage or driveway pavement. (Yes, there's a reason I'm giving you a semi-indirect answer, partly based upon experience.......(;^])
I'd normally want to be much more precise/specific in my answer, but in this case, I think you would be ill-served if I did so. Get the manual.
If I can be of further assistance, let me know. If this helps or solves the issue, please rate it accordingly.
