dana 30/35 build

has anyone built a dana 30/35 with any luck? can the dana 35 be built to handle some abuse and larger tires or is it just a total waste of time and money?

You can get a superior 35 kit which is supposed to make it as strong as a dana 44.
People will probably reccomend just getting a dana 35 it's a great axle.

And a dana 30 should be fine like it is.

you can get new shafts with better alloy then the dana 44 has and it will come with higher spline count and replace the ring and pinion ( they are a weak spot also ) .
you will find it easier just to update to dana 44 or 60

finding a rear end and picking it up, taking it to my guy, doing the swap, it sounds like a hassle. (wich i'm not sure he's done a swap before, he generally just builds them)

it would be much easier to just order parts and drop off the jeep

sorry i tend to not count the mechanical part of the job...i have been working on my own jeeps for to many years..lol i forget not everyone does that part.

so your answer is yes you can rebuild what you have and make them better then new.

do you need a list of places to get the parts ?

I was a busted knuckle garage mechanic in my former life and even I swaped my d44 in my garage using some tall jack stands and 1 buddy to help for pulling it out from underneath. I won't do gears but unbolting the d35 and bolting in a TJ dana 44 was a job that took me about 3 days after work each day.

If you can get lucky with a TJ dana 44 don't be afraid to do it yourself. I'll help with any questions.

Personally after I destroyed the spider gears in my 35 after 1 trail day with 33's I vowed to never put another dime into that POS!

You can build a D35 to match the strength of a *stock* D44. You can build a *stock* D44 to make that built D35 look like it was meant for a go-cart.

Severly over exagurated, but you get the picture...

Swap for sure. If you are going to do any wheeling at all i wouldnt waste your time. Even with the super 35 you only get a few bounces and a shaft pops. Depends how big you are going to go and how hard you want to wheel it.

I have been researching this same thing and I have not heard a bad thing of the super 35. Everyone that has done this mod has only good things to say about it. The super 35 is supposed to be good up to 35's locked...

These wont be a direct swap since TJ's have coil springs and YJ's run leafs. You will have to take a TJ D44 and grind off all the spring brackets and stuff. Then you will have to weld up all of the brackets for the leafs on a YJ.

I am swaping in a ford 8.8. massive tubes, has 4.11 gears, and 31 spline shafts. You have to weld the tubes in place and weld on new spring plates and shocks mounts and few other minor tings. Figure cost of axle.. plus a few hundred more and your good. super 35 kits cost 900-1000 by itself. then install costs..though you do get a locker with it.

Ya after researching, in my area an 8.8 would run me around 400 dollars, plus the 400 for brackets and adapters and diff cover. Then another 1000 to regear, not including a locker. So now Im up to 1800 bucks. I found a super 35 for 800 dollars online. So if I pay 1000 dollars for installing gearing, Im still in about the same spot but locked, although the 8.8 is stronger. If I were to come across a cheap 8.8 in my area I would probably go for it...I wish D44's were more abundant though and cheaper

I would much rather have an 8.8. The axle shafts are beefier and the ring gear is bigger.

Nice thing about yj don't need all the other stuff tj's have.. got the axle for $140 bucks with 4.11's so that helped too. I have seen super 35 do great so no problems there.. I just don't have the money for it.

Ya a YJ swap would be super easy, unfortunately the TJ is a little more involved. I still havent stumbled across one of those fancy money trees

"The DANA 35 is well known for weak, undersized 27 spline axles. These are the smallest axles available in any popular 4WD.
They break far too often, leaving you stranded. The ring & pinion gears, however, seem to hold up well in applications up to 35" tires. So we developed a solution for most Jeep owners: The Super 35 Kit.
This kit UPGRADES the axles to 30 SPLINE! It comes complete with a locking differential ( NOW a Detroit Locker!!), bearings, shims and studs.

Forged Alloy Axle Shafts
30 spline vs. 27 spline
TIMKEN Tapered Roller Bearings
Detroit Locker included!
ARB Locker Available!
Axle Bearings & seals
5-Year Warranty!
No more expensive swaps!"



how can you go wrong with a 5 year warranty?

There is a guy in the For Sale section that sells custom 8.8's at a great price. It was $1400 shipped w/o a locker, and if I wanted a locker it was the plus the price of the locker.

Well its like when everyone started making dana 44 and 60 axle shafts with warranty...if your the consumer your out of luck when they break and you have to send um in for replacement...or you buy two sets right off the bat. If your the manufacturer you get broken crap in everyday that you have to warranty. That only lasted about 6 months if I remember correctly.

The parts should be okay, but the tubes might bend.. I would think about getting a truss on the dana 35 if you go the super 35 route.
