Swapping D30 to D44 Newbie needs help

Hi
I have just returned to the forum after a long time away.

so I'll sum this up as concisely as possible:
-I want to put a Rubicon Next Gen D44 in the front of my 2010 JKU Sahara, to replace my D30 currently there.(which is done)
-So I know I have to change the ring and pinion in the front diff of the "new to me" D44 so it will match my Sahara rear gears that are 3.73:1 This is correct?
-I'm no mechanic when it comes to this stuff, so please be patient (and hopefully kind lol).
-Are there any other things I need to know/buy etc...?
-I know I need transfer case oil, and the new gears, and some way to wire up the e lockers with a switch ,and fuse.

I'm on a budget (a low one) thus the D44 is coming from a wrecker, it was an unexpected (kinda) failure.

any tips , or pointers would also help.

2010 Sahara Unlimited. 33" Goodyear Duratracs, MOPAR Grab Handles front and Rugged ridge in back, SilverStar Platinum Head Lights, Gorilla Pod Video Camera Mount System,Kargo Master Kongo Cage,50" light bar, Rear tail light guards, gas cap cover locking, Smittybilt Jerry Can Holder, with Scepter military can, chopped stubby bumper... assorted decals . Other factory options.

why not upgrade the rear gears to 4.10? Or just pull the front driveshaft until you can save up the money to swap the rear gears.

Why do you need transfer case oil? Don't you mean diff fluid?

1. Not all Rubicon 44's have 4.10s...Some have 3.73's. Check this before considering replacement.
2. If it has 4.10s, swap the rear gears to 4.10...
3. Gear oil 75-90w
4. Wiring with a fuse should be cake, might be tough to find the correct plug.

Thanks Much appreciated. I did some extra homework on this after my post. Yeah a lot of Rubi's came with 3.73.....now to find one. Thanks for the note on the Oil.
I found a video on how to wire the lockers using audio jack plugs I may give that a try.

Do not use audio jack plugs. Get a weather pack connector.
