It is, and it is sought after by a lot of mud runners, because it is fairly strong.

Well I guess that my other question is - I want to put the axels under my 91 wrangler and is it necessary to use the t-case too?

I don't know the number, but it is a Borge/Warner, and its heavier then ^%$&&&%!!!!
look at 99grandtj's post....ford didn't start using the B/W stuff until the early 80's. All New Process in the 78-79 full size. and the np203 and np205 where equally common from what I've ran into.

I know it was done but that meant you had to put in a part time kit or run it in 4 hi lock all the time :thumb:

Just a good rule of :thumb:
I don't know anyone that used the part time kit. I've seen them advertised years ago. But I did know many guys running just lockouts.

That's just cuz your a young punk kid.:sonicjay:

Full time 4 wheel drive was common in the late 70's & with the gas crunch, many people switched to part time conversions for the economy. My dad did it on at least 2 different Suburbans.

Ford 9 inch (back) Dana 44 (front)
Yes. The front axle will have the less desireable cast ends.

As Adam said, it is not. However, the thing you need to consider is that you want to put this stuff in a YJ. My opinion is that you should skip the 1/2-ton stuff since you would be changing bolt-patterns anyway (unless you already bought wheels) and target a 78-79 F-250 HPD44/D60 and I'll tell you why:

  • 78-79 F-250's & F-350's are leaf sprung and share the same perch spacing as YJ. Broncos have a different suspension system.
  • 78-79 F-250's & F-350's are SOA from the factory.
  • The 78-79 F-250 HPD44 is the beefiest stock D44 you can get. Comes with dual-piston calipers, flat-top knuckles, 3" tubes w/0.5" wall thickness, and lockouts. Axle ratio is commonly 4.10 as well. You won't have to worry about the D60 rear until you have enough power to break it.
  • They will bolt right into your YJ SOA. The 78-79 F-350 HPD60 is configured the same way. Once you set up the HPD44, no changes are required to swap in the D60 if you ever want to upgrade.

If you want a good reference point for this axle set, see Leanz's Rig Build. She started out on her YJ with the HPD44/D60 and now has the HPD60/D60.


If you would rather stick with 1/2-ton axles, you would want a 77-down HPD44 to avoid the cast ends. Read up on the first two links here: http://77cj.littlekeylime.com/web_rs44.html :thumb:

Nope my old beater suburban had a np208 case...the wifes Burby has the piece of crap nvg243 I believe it is..the autotrac tcase.

altho' we did convert my buddys '78 burby to lockouts and he kept the 203 tcase.
