Ox Locker installed

Easily the most expensive mod I've done to date:

Ox locker- $900
Locker cable (125")- $140
diff overhaul kit (bearings/races/bolts)- $200
River Raider shifter mounting bracket- $50
Labor- $200 + 6 Red Bull energy drinks
Machine shop (details below)- two cases of Bud Light

Being the 1st JK Unlimited with a rear Ox- priceless In fact, according to Ox, the only other JK version out there is on River Raider's 2dr.

No need to go into details on the assembly and install of the Ox as the Ox instructions are pretty straight forward click here for Ox Instructions- warning, large pdf file!

there is only one problem with the Ox instructions: on page #3, step #6- It appears that you simply screw the cable end into the cover. However you can only screw the cable so far before it disappears into the shift fork. Once the cable is in there, you have no way to hold on to it in order to screw it in further. And at that point, it is only about 1/2 way from where it needs to be. Took quite some time to figure out that you have to remove 2 c-clips that are holding the fork, then unscrew the fork assembly from the diff cover. Once all of that is removed, you can then screw the cable the remainder of the way that is necessary.

Rear opened up and getting ready to start working




Introducing the Ox to my ring gear




Then the BIG problem hit. Some early '07 models (after they switched from D35 rear to D44 in all models) have 1/2" ring gear bolts. Later in '07 (and all since then I believe) have 7/16" ring gear bolts. Well of course Murphy's Law- mine has the 1/2" bolts, and the Ox holes were made for 7/16" bolts. I thought my day was shot right there. There is no way possible a drill press is going to drill larger holes in that Ox- that steel is seriously hardened. Lucky for me, there is a machine shop right behind RockRash4x4's shop, and a couple guys were there working on stuff. George talked to them and they helped us out. Did I mention that the steel is hardened? It took them 3 HOURS and they destroyed 2 endmill bits (I think that's what those bits are called??) drilling out the holes for me. Payment was a case of beer I bought them 2 cases since they saved me!

I won't bore you with the details of routing the cable. Anyone that is interested in seeing the cable run, click on thumbnails:






Cable routed, and shifter mounted- notice the RockRash4x4 custom touch- he powder coated the shifter nob black, but left the knurled portion of the nob un-coated (I love the look). He also powder coated the shifter plate (where the X and O are), then grinded off the powder coating leaving just the X and O in black- a really nice touch IMHO.

Finished











And while RockRash was busy with the technical stuff, I was busy with the non-technical: I painted my jerry can holders black, painted the jerry cans olive drab, and painted my muffler high-temp black

Too Cool I just had my rear locker replaced and the Jeep tech told me it was the early 07's like I have that had the 7/16" ring bolts. Mid 07 they switched to 1/2". They had to replace my ring gear also since they could not get a carrier to match my 7/16" holes.

I thought it was the other way around. Mine has a build date of June '07. Terrahawk had the same issue with his '07 when he installed an ARB- the ARB came with 7/16" ring bolts.

Yours should have the 1/2" bolts but don't hold me too that..
Mine has a build date of 12/06 and has the 1/2" bolts. It may be hit or miss on the 07's.

When I had my 5.13's installed they were tapped for 7/16 bolts and we had to sleeve the bolts/carrier to use them.

EDIT: I thought they went from 7/16 bolts to 1/2 bolts in 07 because they were having problems with the diesels JK's sheering bolts in the ring gear. Thats why my gears were tapped for the 7/16 bolts.

my build date was Aug 06 and it had the 7/16" ring gear holes. They beefed up the mounting to 1/2" mid year of the 07 builds per the Jeep tech. That was the problem. A lot of the companys did all their prototyping off of the early builds and then Jeep changed up on them.

Anyone with an '08 have any experience to chime in with?

With the amount of ARB's that are being installed, you would think that they would assume that they would be shipping it the way the "majority" of rigs have. So if you go by that assumption, then since they are shipping with 7/16", that would mean everything after '07 has the 7/16".

Sure ia a PITA that us '07 owners have differences. And the only way to know which one we have is to open up the diff and pull the carrier.

This is a quote from four wheeler http://www.fourwheeler.com/projectbu...les/index.html

"And don't forget the gears, which are the only gears on the market to have a dual bolt pattern designed to work with one of two possible bolt sizes (midway through the 2007 production, Jeep upped the ring bolts from 7/16-inch to 1/2-inch to accommodate overseas diesel models). Even the installation kit comes complete with both sets of bolts, so no matter what setup you have, you are covered."
