2005 TJ Dana M35 to Dana 44

I have begun the search for a Dana 44 rear axle assembly. I am finding used axle assemblies out of TJ Rubicons and the prices are all over the map. My question is, will a Rubicon rear end bolt directly into a Wrangler X? Am I better off dropping the coin on a new built Dana 44 with disc brakes($3,500.00), whereas a used unit goes for $200.00 to $2,000.00 and plus the cost of a rebuild, disc brake conversion (?) and re-gearing.

It will bolt in. The Rubi D44 is the same as the other TJ D44's plus a locker.

I have a Rubicon D44 in the rear of my 04 X. Along with dealing with the locker and possible rear driveshaft length, you will need Rubicon e-brake cables. Also the yoke on the Rubi D44 is the bigger 1330. So changing the yoke to 1310, or running a combo joint is needed.
Then, you'll need to match your gears front and rear.

Mine came with an ARB, 1310 yoke, and 4.88s, so it was an easy swap for me.

If you don't mind me asking, what did your swap cost in round numbers. I am trying to decide if buying a unit would be better for me, I am aware of the drive shaft modifications needed, but was unaware of changing out the yoke. It is in my plans to re-gear the front Dana 30 to match the rear.

Sure it is without gears and set-up, and its still not as strong. The ring and pinion size is its limiting factor

yeah and you will never break a R&P unless you are extremely stupid. So if you break one you deserve it.

BTW the axle shafts are the EXACT same size. Not to mention the parts to build an 8.8 will be over 2k so your not getting one to you door for much under 2750. An arb for an 8.8 is over 100 bucks by itself, a super 35 kit with an ARB can be had for under 1200 bucks.

The axle shafts are what are considered weak on a dana 35. The R&P is not, infact the contact patch (which is what matters in terms of R&P) its nearly the same as it is on a dana 44, the difference in strength of R&P on a 35 and dana 44 is marginal at best.

Sorry but spending more then double the money for something you have to be completely stupid to break is dumb in itself. Now if you go full retard up everything then no matter what axle you put under your jeep you will break it.

Also when you wheel long enough you will notice guys that drive stupid break stuff no matter what they got, smart driver rarely break things and spend MUCH less money on their rigs.

Do some more research. You think its just a coincidence that every one says dont put money into the 35 or maybe they dont know what their talking about either?

Which is the better axle assembly to put in, a Ford 8.8 or Dana 44?

In my research I am pretty convinced that I should use Eaton E-Lockers, I'd use ARB but with the supplemental breaking system that I currently have under the hood for use when it is being towed behind my RV, there is no room under the hood for another compressor.

I paid $1800. Came with 35 spline Ten Factory chromo shafts, ARB, 4.88s, Poly Performance shock mounts, and some HD bracketry. It was ready to go. I bought it from a great guy who recently moved to your neck of the woods and opened up a 4x4 shop. He knows his stuff, and I would recommend his shop for any of the work you may need done.
If you want, I'll PM you the name.

i do do research... and you will never find anyone with FIRST hand knowledge of super 35s that does not like them, what you find are the ignorant internetregurgitators that have no real knowledge of how axles work.

Also if you were smart enough to do research you would find that there re more TJs and YJs wheeling with dana 35s in the back of them then any other axle, they do not all break like the internet says.


I bet you also didn't know there are a few teams that run a super 35 at KoH. Stop spreading your own ignorance and actually do real research.


BTW an 8.8 is still a c-clip axle with the EXACT same size "1.31 inch diameter) shaft as a 44 or 8.8 in a super 35. The ring gear is not a weak point if you understood the physics involed in how a dff works you would know that. Its not an issue with a jeep motor, if it was it woul not of been used for nearly 30 years.

Got any names of these teams running super 35's in KOH?

Something to remember, its possible people didn't have as many problems with Dana 35s in yj's simply because the average "offroad" tire size was much smaller. My dad tells me stories of back in the 90's where he was shocked to see a rig running 35" tires on the Rubicon. He and most of his friends ran 31" and they would occasionally see a rig with 33" tires, but even that was uncommon. He went on to break his locked Dana 35 on 31" tires one trip and replaced it with a Currie 44.

What would you say is the most common tire size now? 33"? Maybe 35"? My point is we demand more out of these axles than we did back when yjs came out with Dana 35s that didn't seem to have problems.
