Sport to rubicon front axle swap question?

So I found a 2010 rubicon front housing shafts and gears for a good price and was wondering if it would be a direct swap to my 2014 jk sport?
I would need to buy a locker/ carrier that's all that's missing I believe.
And I would need to regear my rear as well I know.

Define "good price." You can buy a new complete Rubi axle for under $2k.

A locker for that axle will run about $800. If I recall, the ARB goes to 35 spline, so you'd need new shafts as well.

The Rubi stock carrier is a pricey piece.. Carrier options are limited due to metric bearings in the D44. Remember, the D44 housing is exactly the same strength as the D30 housing. The only advantage of this swap is bigger axles and, ring and pinion. If you are looking for structural strength add a truss too the D44 before instal.

The housing with a master rebuild kit and a set of 4.88 ring and pinion for 575 OBO but it's still up in the air I just was t sure if the years were comparable

And I would just beef up my Dana 30 because I'm not really doing any hard core off roading but at the same time I still have a payment on it and in order to put new gears in I need to buy carriers/lockers anyway due to the fact that I have 3.21 gears.

You will be looking at another $1500 at least for locker and axles to add to your $575 to get that all together. Now you are over $2k and no labor charges yet. I'm gonna say you will likely hit $2500 before it's in and running.

Where do you see NEW complete Rubi axles for under $2k? That has me interested. I occasionally see used ones complete for around that but not any new ones unless you are referring to low miles pull offs as new. Which I do consider the motor I put in my jeep "new" since it was pulled out of a brand new 2011 jk with 22 miles on the ticker. Just curious.

There was/is a place in OH that was selling them for around $1800, or for $2000 any gear ratio you wanted. Three people in my local club each picked one up and I know a number of people on the other forums that did as well. I installed two of them and they are legit. Not sure I can find the link again though. The price on Rubi axles has come down a lot. I just saw a used front selling for $1500 and it sat for weeks.

I no longer see the point of replacing a D30 with a D44 unless the D44 is either, aftermarket or trussed.

If the D30 is bent and busted, by all means upgrade but you best truss the D44. If you bent a D30 you will bend the D44 as well.

Lol.

Probably true - especially if the mechanically unsympathetic habits that bent the first one are repeated...

Personally, if I bent a stock housing, I'd retube it with 1/2" wall and turn the Cs while I was at it. You have a PR44 housing for under $200. And obviously truss it too since it is cheap insurance.

That's what I did, works like a charm. It's a hell of a stout axle now.

And Dynatrac will also sell the PR44 end forging. Apparently, it isn't too pricey either. Although, the stock one with gussets is just fine.
