Gentlemen, I just purchased a 1984 F150 XLT Lariat 351W 4x4 Automatic Trans. I'm very new to 4x4, as this is my first truck. So, please excuse my questions, if they seem very simple to you all.
1) The Cert. Label lists the Axle Code as 193, I'm not finding this anywhere, what is it?
2) The previous owner stated that "Rebuilt Axles w/rear 8.8" Detriot True Track and 4.10 gears" what brand oil and poss. additives should I use to change it out.
3) I'm assuming the front is a Dana 44 (maybe) what recommendatiosn do you all have on oils / additives.
4) It's running a C6, again what fluids do you all recommend for the tranny?
5) How can I tell which type / model of Transfer Case I have? The Haynes Manual I have shows three types, buy mine looks different than those. I also wanted to onte that the Locking Hubs are installed on this model / year.
6) Which oil / additives do you all use in the Transfer Case?
Again, sorry for the questions, but I'd rather ask you all (4x4 runners and expects) than play guessing games.

well, mercon 3 in the tranny, 80-90 weight in both of the differentials, no additive is nessesary. Is the transfercase aluminum or cast? If it is cast use 80w-90, if it is aluminum use ATF. What is the shift pattern like for the transfercase, my 205 front to back is 4lo n 2hi 4 hi. I think 1446(is that right?) is 2hi 4hi n 4lo.
If all is peachy keen, your transfer case will have a tag on it. I think your case is going to be aluminum regardless. I think it will either be an NP208, or a Borg Warner, but I am not sure of the model number on the BW.
Well gentlemen, I tried the Magnet Trick and it didn't stick, thus Aluminum Case. Is there a Web-Site that shows pics of Transfer Cases around my year of truck, so I can determine which model of Transfer Case it is? I looked for a tag, but there is none.

This axle code is a 19 for a 3.55 open and the 3 for the dana 44 front open.
2) The previous owner stated that "Rebuilt Axles w/rear 8.8" Detriot True Track and 4.10 gears" what brand oil and poss. additives should I use to change it out.
I'd be checking to see if there was smoke blown to get you to buy this. I'd pop it open when you drain it and look. A good 75W-90 will work. If it's fine condition a synthetic will be the best bet.
3) I'm assuming the front is a Dana 44 (maybe) what recommendatiosn do you all have on oils / additives.
See the recommendations for your rear... both of these should have worked on if the previous owner threw 4.10's in it.
4) It's running a C6, again what fluids do you all recommend for the tranny?
Brand name Mercon III, blow air through any cooler lines, then flush, change filter and gasket.
5) How can I tell which type / model of Transfer Case I have? The Haynes Manual I have shows three types, buy mine looks different than those. I also wanted to onte that the Locking Hubs are installed on this model / year.
Usually the xfer case is stamped. You could have a NP 208.. this has NP stamped on it. You could also have a BW 1345, this is a ribbed case, both are aluminum. Best bet is to look for casting numbers or other identifiers. If the previous owners changed the gears then maybe they changed out your xfer case as well.
6) Which oil / additives do you all use in the Transfer Case?
All aluminum cases, to my knowledge use auto tranny fluid, so Mercon III would be the choice.

It's good to be safe, but I'm wondering what hasn't been disclosed by the previous owner. I'd have never bought the truck with out checking the numbers first and knowing what it was I'm looking at. Chock it up to being in the same position you're into now.
Kerry, thank you for taking the time out to answer my question, but answer me this.
If the Carriers are Open, how can Ford advertise this as 4x4? Open carriers place power to one or the other wheel, not both at the same time (like a posi unit)? Right?
Yep, one tire at a time, that's an open. It's something that all manufacturers do, Ford's not any different. You'd have to place a locker and/or limited slip in front and back to make it a true 4X4. Most people are of the mind that if they can't see it then it must be true. Most people don't really pay much attention to 2WD or 4WD the way you did. They think both wheels turn in an open diff, well they do, but they don't drive the vehicle. Unless you jack the vehicle up and show them, they just don't understand. Most don't really care, as long as the vehicle goes down the road.
It's not technically correct to call it a 4WD, but I really doubt a lawsuit or anything drastic would fix what's been going on for almost 50 years. I'm thinking that it's actually been going on longer than that. Don't recall if some of the Jeeps were open front and rear that the Army used.
Just be glad that you know the difference and can tell those who don't so that they may be educated as well.

Well, both wheels do drive the vehicle, just until one wheel has less traction than the other... There is no "drive" wheel per se, just that when you lose traction, the power takes the path of least resistance at the spider gears... Alas, no matter how many times I explain how a differential works, some people just never get it....
