What do these numbers stand for?
 
Ok, Here are the numbers off of my axle housings. Which are supposed to be D 44's out of a 78 waggy.
Rear:
US PAT
1868618
and
44-1

Front:
0-53789
and
30-1

Can anyone tell me what these #'s mean?
I bought a gasket for a front d 44 from a 78 waggy to day, and it didnt fit, I ended up having to get a gasket for a 66-67 v6 CJ5, and it says they are for spicer 30's. Could the front be a spicer 30 and the rear be dana 44? Both axles housings look identicle, and both have drum brakes. I checked the gears and when I divided ring and pinion I got 3.307, for both rear ends, so I do know the gears match

By the numbers 44-1 and 30-1, you definitely have a 30 front & 44 rear. The other numbers can't tell me what you have. There should be a 6 digit number then a dash, then a 1. Thats the number you need to find. It'll be on the longer axle tube about midway towards the drums, facing the diff cover side (usually). Are they 6 lug or 5? If six, then they're waggy axles. If they're five lug, it sounds like you either have cj axles or Commando axles. What width are they? Waggy axles are around 58-60". I attached a file with all the BOM#'s. Just look up the number from your axle and it'll tell you what you have. Just disregard the -1 as the BOM's don't have it. Hope this helps!

I'll get those numbers tomorrow..




Ok I found a picture of a 2 piece rear d 44,
http://www.jeeptech.com/axle/d44wag.jpg
Mine is slightly offset, and doesnt have the caps on the end of the shafts for the nut.
Mine looks like this

also found a pic of a 27, and 30, Mine looks like a 27,
http://www.jeeptech.com/axle/d25.jpg
but instead of one joint bar for the steering, I have 2 seperate bars like the dana 30 http://www.jeeptech.com/axle/d30.jpg
My housing says 30-1, and I was told that is the model number, but yet the page I found these pics at said 30's didnt have closed knuckles. I also found a pic of a 72 jeep.

And it looks just like the jeep I got the axles from. Same color and all. with d30 front and 44 rear.

Is yours 5 lug or six? The old Jeep Gladiators had closed knuckle d30's in front & 44's in the rear. Also the 72-73 Commando had closed knuckle d30 front & d44 rear. Yours is a flanged d44 rear with 30 spline axleshafts. The one with the caps is a 19 spline 2-piece rear axle. Really worthless. The 30 front can be changed to disc's with most junkyard parts from a newer 30 axle or a mix of chevy d44 front axle parts and 78-79 cj parts. Hop over to the Jeepster board and do a search on front disc swaps. You'll find alot of info from there.

Mine are 5 lugs.
What would It take to convert the d44 rear to disc too?

D44 rear discs aren't hard to do. You can either buy a kit for around $299 which is complete, with instructions, or go with junkyard/auto store parts. I found a good source for the bracket to mount the discs at CRL Customs . They're only $10 a bracket. Advanced adapters sells them for $60 I believe. Then you need rotors, rubber brake lines and calipers.

I got the 5 lug, same as ford d44..... could I used disc brakes from a ford, to do the conversions?

Re: What do these numbers stand for?
 
That I don't know. You might want to ask a ford guy on their board. I've heard of using ford parts up front to keep a 5 on 5 1/2" bolt pattern, but never on the rear axle.
