Robb's 08' JKU Rubi Build(AKA Sarge)

New to the form but not new to the Jeep world. Owned a TJ for 8 years and built that up. Had to break down and buy a JKU. Have 2 kids that I want to take wheelin. So found a 08 JKU Rubi that is extremely clean and only 23,500 miles on it. Did a ton of research on lifts and long arm kits. Came down to Poly and Teraflex. Ended up going with the Teraflex do to cost of Poly. Did the 6" elite long arm from teraflex. Also did the matching Fox racing resi shocks. Front inner axle tubes and inner c braces. Also installed the spin tech locking hub conversion and up graded to all new chromoly axle shafts front and rear. Added 37 13.50 17 Toyos with race line monster bead locks.
Jeep rides better than and handles like a car. Very pleased with it do far.
Future add ons will be custom built sliders w/ PSC rocker armor, customer bumpers, on board air, gears, and 1 tons.
Enjoy!

Before any mods. The way I bought it



The start of the Madness

Wow, you did a great job man. Sweet, sweet build.

Wish I was a DIYer. When I get a real job and house maybe one day I'll learn to weld.
Thanks!!! It has saved me tons of money. Only into the front bumper and sliders for $110 in materials. Including paint
you got some great fab skills man, everything looks very good nice work

Thanks.

Give you guys a little update. Took her whellin on the Rubicon back in August. Had a great time but had so failures. The right front ujoint failed. It was made by Persion "thier super streght line". Less than 8 miles an it. Obly used the front locker maybe 6-7 times. I was pissed almost made to Buck. So wheeled it back to Eli's in 2wd low. I have to tell you guys I and very impressed with Teraflex's products. Very strong, side hill was very stable, excellent traction, and drove like a dream home. When getting out if the spot the ujoint broke I was backing up and high centered on the rear driveshaft and belly. Bent to rear aftermarket driveshaft " it had .083 wall what the driveshaft shops recommend". So upgraded it to .120 wall". Then one the way almost to the slabs I had to go down a little hill with a giant rock on the DS the size of a Jeep and since to didn't have traction in the front to help hold my line the rear slid right into the LR corner. Now that really Pissed me off. But now gives me a reason to build some tube fenders.
Here are some pics. Enjoy!

Took a little break building the beast. Back at it again. Was going to build tube fenders but decided it was going to add too much weight. So bought some Bushwacker Flat Fenders. Once I installed the fenders the 37's looked way too small. Put some 40's on it and niw it looks much better. Also bought RCV 300m front axle shafts for the front. In the next couple weeks I am going to build some different rock sliders, rear bumper/tire carrier and front stinger and grill hoop.
Enjoy





This pic is when the 37's were on it.

Nice build. Yeah I have a tf 4" lift. 6" is really ideal I think.

I thought chromoly was a very good idea to go to for all your shafts. How did you brake the cross on the joint like that? I did that to a basic moog joint but I wouldn't have thought of that happening with a chromoly shaft and joint.

Do you think you will consider rcv's now? Edit - I didn't realize there was a 2nd page. So you have rcv's. good stuff.

I run bushwackers too. Seem to good. I like them.
So 40's on the 44's? Wow. Let me know how that goes. I have thought of running tires that big but wasn't sure of the needed offset for the tires and its effect on the unit bearings and overall strength of axles for tires that big.

I run that. Get it tig welded for extra strength. Or you can get 1.25" Dom threaded from a supplier. Forget the name but I can find it if anyone would like it.
Sweet rig. Great job on the fab bumper.

The u-joint was a Presision cryogenic Joints. Problem was the shafts were bottom out on each other causing the joint to fail. The front housing is sleeved and gusseted and I am going to fully truss tge front and rear. The 44's should hold up ok with my driving style. I drove a 2001 TJ fir 8 plus years with a D30 in the front and D44 in the rear on 35's and never had a issue. Key thing is to pick the right line and nit try to prove anything. I will winch or stack before I get to the point of breaking.
So Robb,
Rcv's work with spintech? I have a set and was thinking of doing the spintech upgrade. Do I need a different rcv stub shaft or is there machining to be done?
The outers are different. It uses 30 spline outers that are 9.94" long. No machining required

Yeah I don't get it. I have been looking at this. Don't see how a rcv stub shaft works with this setup. I believe you that it works, but I am funny that way where I need to know how it actually does work. I will ask rcv or spyntech I guess.

Edit - found my answer here.
http://www.jk-forum.com/modified-jk-tech-2/pro-steer-ball-joints-rcv-shafts-193458/
In short the rcv stub shaft has to be ordered to work with the spyntech hub conversion. Sucks. That's going to cost a little more but on the other side I can ordered setup from spyntech without front shafts thanks for the info. Got me pointed in the right direction.
Yea you will have to order new stub axles from RCV to use the spin tech hub conversion. When you order from RCV tell them that you need 30 spline 300m outers for the D44 9.94" long. They will know what you are talking about. They are very knowagable and have great customer service.

So started some more fabing on the JK. Bought a Artec Front axle truss and armor kit. Kit os extermly clean and very simple will take lots of pics over the next few days. Also picked up the rest of my steel to build my rear bumper, tire carrier, and different sliders. So here a few pics to start off the front trussing and axle replacement
Enjoy!
