locked front options
The stock D30 and D44 use basically the same weak housings, the only difference is that the center section on the 44 is larger. You would want to do all of the same strength upgrades on the 44 as on the 30. What the stock 44 will give you is larger inner axle shafts and bearings, the failure prone elocker, and the JK D44 R&P, which is actually a significant improvement over the d30 gears. The outer shafts, knuckles, brakes, etc are the exact same.
Add up the costs for that new rubi axle, and see what you come up with:
Rubi front 44 - $3000
Gears - $600-$800 depending on area (since it comes with 4.10's)
Wiring and switches for the locker (haven't priced it, but $150?)
Sleeves, Gussets, Truss, Skids, Alloy shafts, HD mounts, etc. - $1500 ?
And you end up with a built up 'stock' axle that is more expensive than a PR, and is still a lot weaker.
Just my opinion, but the only time a Rubi44 makes sense is if you already have one. (or possibly if you can score a killer deal on a used axle and plan a slow build?) Buying one new for 3k is just throwing money away.

And if it breaks you are not out that much $$$.
You did notice the very first thing he said, right?
As you can see go get an Aussie, install your self, and have a fun.
Agreed

im waisting about 1000 dollars but it is a temp solution untill I can get everything else done and then get a pr
It truly is amazing how people running a D44 or a D60... pooh, pooh the D30..
True there are stronger axles out there.. but seriously people have wheeled this axle for years with good success, Read the FAQ section for it's limitations though.
People are always willing to spend "your" money.. Or waste it..

For your reference to the faq's, read this one. You will notice it was started by the same person that wrote the faq's, and he has done a 180 in his opinion...

There really is a reason that so many of us are upgrading these stock axles...

^^^ So true!
Prior to the JK, I can't remember (in over 20 years of wheeling) of a similar failure in a Dana 30 front housing. All previous 30's have had their own issues but nothing as serious as the present JK 30.

The JK version is 5 inches wider and has taller C's. It is much more prone to bending. And then there is the suspect metallurgy in these JK axles. How many previous 30's or 44's have you seen shatter just from running up onto a curb?

Let me say it like this,
I hear what you are saying and I agree to, C gussett's should be done imo to the stock front axles.. 30 and 44 respectively. the 44's are bending as well, so i don't see why people talk like the D30 is that much worse then the stock D44, especially when you are running 33's...
Many people have run this axle D30 on here for a long time. So it really does work for some people. and as you know we are seeing 35's as the marginal setup at best.. although imo I wouldn't, and even a few are running 37's..
I know one personally and it's held up for a year now of moderate wheelin', but he is a well seasoned off road driver. That helps alot for sure.My thought's we'll hear more breakage from D30's because there are more out there in service, then the D44 fronts.
The JK weight is heavier too, not a good thing for off roading, but you have a HPD30 which is stronger at the third member then the TJ's had, so I still think this axle is acceptable on 33's for most people on the trails.
I know you wouldn't spend a dime on the 30, but with 33's tires...? Too many people are using this set up with success. imo, you don't have to spend 5K on a new front axle to go wheel moderately with this set up. that's all I'm saying.
Totally agree about if you do upgrade the axle get the PR..
I have read many of your post and KNOW you say to not "waste" money on the 30 but YOU did not read his post. He said the 2.5 coil lift is on his wish list....dude, ain't got 6Gs to "waste" on a new front-end. And he CANNOT get gears and ARB for $1,500, the ARB/install alone will cost that. Gears are another $1K = $2.5K YOU missed the point of HIS thread. He wanted more capibility and YOUR point was to "upgrade" the whole da*n front-end.
Yes, he wanted a selectable but hey.... we are all not rich and can dump +$20K into a jeep. The guy wants to have fun and he should be able to without guys expecting someone to spend a fortune just to drive a GD jeep off-road. It is nice to have toys but enough of the elitist BULLSHIT.
