Huh. I also did not know this. Good to know thanks a lot, I was about to ask the question myself.

Everyone I know usually keeps their rear locked on anything with decent sized rocks. g-rocc is your rear locker usually on ?

Only rubi locker I've seen boom happened when my bud karl experienced his rear UCA axle side mounts ripping off, destroyed the DS u-joints and breaking a rear cromo on the Patriot exit. But I think the stock welds were at fault for the whole shebang.

Only when needed. That being said, I'm locked front and rear the entire time on some trails (patriot, carnage). On trails like chinaman I only lock up at the big obstacles.

The kit is from a yet to be named vendor in NC , and depending on how all this works out I think they may offer a JK gear swap kit .
Looking forward to this.

OkLaHoMaTJ- I tried to reply to your PM, but your box is full.

I received most of my remaining parts needed to complete Greg's axle upgrades today. Tomorrow I should be emailing him some pattern pix if all goes to plan.

From all I have read keeping the rear locked will help it live a lot longer , and it also sounds like I need to stay off of Patriot .

In the past I would unlock after major obstacles , but the rear will stay locked offroad as cheap insurance from now on .

After a 13 hour day today (about 3 on Greg's LJ) I'm just too pooped to upload my pics.
But...the front is done. I got the rest of what I was needing to properly set pinion depth and went to work. Stock pinion depth was 0.056" and the end depth with the JK gear swap was 0.291". I was able to shim 0.050" behind the pinion race and use 0.056" via a large slinger to keep the pinion bearing bathed in oil. The rest was OEM JK44 shims placed between the slinger and bearing. I was able to use some leftover OEM Rubi 44 carrier shims to set backlash. All in all, it looks like a factory install aside from the large stack at the pinion (which you can't see).
I'll knock out the rear tomorrow afternoon. I measured the stock rear pinion depth at 0.055" today, so I'm confident I'll be able to start at close to my final stack height from the front and be much more time efficient.
I'll do more of these in the future I'm sure. Typically I can regear a set of Jeep axles in about 4 hours. This swap has long surpassed that time allowance. But you don't learn new things until you step outside your comfort zone occasionally!
I hope to be driving it Friday to break in the gears if all goes to plan.

Just got home from the three hour tour with 5.13s . First impression is that one of the noises that bugged me is gone ! The gears make a huge difference in driveability in town and up the hills . Once the trailer is loaded up I think that this is going to be about perfect for our trips . It may be a little too much gear for some of y'all , but it is turning 2750 rpms @ 65 mph and thats about as fast as we ever go . Jody is going to post up some install pictures this weekend , but until then heres some pictures from U Joint Off Roads shop ...



The owner calls this one V4.

Not sure of the name of this one other than awesome . http://ujointoffroad.com/

So thats it for the night , made it home with a big ol grin thanks to the gears .
