AXLE question>>>

Good evening to all,
Ok now that I have spent the last few days reading post about axles I am more confused then when I started..
So I am going to do the unthinkable. I thought that there where Dana 44 axles out there that would fit my CJ 5 with out major modification. I am currently running a Dana 30 front and a AMC 20 rear. I would like to be able to run 35's. Everything I read says don't do it with my current set up. I also want to get rid of my drum brakes up front. Thanks in advace for your time and help.

So what is the unthinkable that you're considering?

I don't really see anything in the post that's a question or a plan of action.

A rear Dana 44 from a 72/73 Commando or 72-75 CJ5 is the closest you will find for the rear. Only needing minor spring pad and shock mount work. They are the same width as what you have.

Disk brakes can be had by swapping out everything from the balljoints out on any other disk brake CJ Dana 30.

There are other ways to achieve disk brakes but this is the simplest.

35's will put a strain on a stock 30/44 combo.

ok thanks for the help. I would like to upgrade to bigger axles. I thought that i read some where that you could find dana 44's that would fit my short/narrow wheel base CJ. I was think of scouting some junk yards over the next few week to see what I could find. I just wasn't sure where to look or how to tell what I am looking at. What is a wide trac and how can you tell? Would wider be better?

There aren't any front Dana 44s that are a bolt in. There's a crap ton of info on this forum alone on Dana44 swaps.

Any '82 and newer CJ7 or CJ8 has wide track axles. They are about 4" wider than 81 and older axles.

I got a 44 out do a 70s waggy and narrow the long side like 4" so it would be centered and the spring pads would match. Had to get a shorter axle reworked for the long side and the whole a lie was wide track width (58") as I recall.

Anything is possible if you don't know what you are talking about.

The easyist and cheapest upgrade - to run 35s - is a set of wide track 20/30 axles AND one-piece axles (for the rear).

But... if your goal is hardcore wheeling and lots of it, I'd do the (additional) research and look into a 44/44 or 44/9 setup. Only because - after gears, one-piece axles, lockers... the $$$ will add up quick. Might as well start with something better

I am not a hardcore wheeler. I am more of a overland guy. Everything I have read about my current set up is 30/20 they are junk. Most people go on to say they are not worth the money to up grade. This my first jeep so I am learning as I go. I have read several axle swap threads, but like I said in my first post I felt more cornfused then when I began. again thanks for your time and help.

dana 30 in the front is fine. friend of mine has a 70 bronco with a 30 in the front / powerloc, and he has a stroker 351 windsor, think it a 400 +. hes never had to rebuild or upgrade hes front end, hes upgraded his rearend but not the front 30.

The AMC 20 is not junk. It can withstand some improvement, however, as can ALL axles. The most common is the one piece axle replacement. This corrects a weakness in the axle construction that made perfect sense economically for AMC. The other upgrade is reinforced welding of the axle tubes to the differential and adding a truss to the assembly. Many argue that doing this brings it up and possibly surpasses the strengths of a Dana 44. These improvements can be done to both the narrow track and wide track axles.

My style of Jeeping sounds very much like yours. I run 31s, so take that into account, but the only improvement I felt needed was the axle swap.

My word of caution to you is this: It's YOUR Jeep. Build it to please YOU. Be wary of others who would happily spend your money building your Jeep into the Jeep THEY want.

I'd rather be lost on the trails than found at home!

This maybe a stupid question. Can you run a dana 44 or another bigger rear end with a dana 30 front. Will you be able to get gearing to match. Thats my next question I currently have 3.54 gears. In some of the post that I have read most dana 44 have 3.73 gears. Would it be better to go with 3.73 gears or stay with the 3.54's?

With a 6cyl, 3spd and 35s?.. I think I'd opt for something more like 4.56s or even 4.88s.

We did a Waggy front D44 (about 60-61" wide) and a Scout rear D44 (about 58" wide) on my buddy's CJ7. Although the axles were wide, they didn't look out of place.

We outboarded the front springs on the frame rails to match the Waggy perch width, and simply moved/rewelded the rear axle perches for the rear.

On my own CJ5, I've got a narrowed Waggy D44 up front, and Scout D44 in the rear.

Are you able to weld/fabricate? When it comes to swapping axles under a Jeep, you either weld/fabricate.. or throw money at it.

That's the way I'm going after tons of research. For the moderate style of wheeling I do, it seems like the most bang for my buck.
44's don't seem to be that big of an upgrade, and anything bigger I believe would be overkill, and throwing money away.

Plus I want to keep my tires where they are now, about 1/2" past the flares.

Any '75 and older CJ came with a Dana 44 rear axle.

Most '72-75 did come with 3.73s (4.27s were optional), but there is nothing to stop you from changing gearsets.

As Besrk mentioned, neither 3.73 or 3.54 would be a good ratio for 35s.

I would upgrade the AMC 20 before looking for a Dana 44 though, unless you have a good source of D44s.
