A customer of mine just sent me the Photos of their new JK with the Mods.

I was their trail guide last year at the SW4WDA YO Ranch Run and they fell in love with the Jeep Lifestyle.

So they ordered a new JK in October and traded off thier 2005 "X"

Yes; the plan to be at the Texas Spur Jeep Jamboree in Llano, TX later this month

They picked up thier new Jeep on March 6th and yesterday added all their new googies.


Check out this hot looking Jeep.

Thats a good looking Jeep!!! Hope to see them @ EJS!!! I just played the driveline rodeo with mine today. I needed tequila to relax about it. There are some things I will NEVER understand why they did it on these Jeeps. I am going to make a prediction, right here, right now. After tearing open my driveshafts today for a "look-see" I predict that ANY lifted JK with more than 5 degrees of misalignment in the driveshaft will SMOKE them within 10,000 Miles. Predicted here, first.

Hummmmmmm

I know you drive a four door so I assume the Greater then 5 Degree would have to be a 5" lift.

Would that be a 4" lift on a Two Door?

I thought he drove a four door!

Nope, Joe has a 2 Door Rubicon. And the misalignment of those drive shafts is too much with about 3" of lift on them. Maybe 4 with the 4 door.

Nope. I have a 2 door. At stock height, they are between 3 and 5 degrees from center. By natural design of the "Rzeppa" joint, they are VERY strong from zero to 5 degrees of misalignment. From there , the strength goes down exponentially very quickly!!! We tore my driveshafts apart yesterday to get a closer look at how these things work. As my driveline guy and I stood there shaking out heads, he looks over at me and chuckled and said: " Well I guess that we need to get some of these conversions built, because with the number of people lifting these things, we are gonna sell ALOT of them" You see, when we tore them apart, we got a good look at the design of them. There are 8 (eight) 5/8" balls in a cage in there. when the joint is within the 5 degree range, all eight of those balls are fully enclosed in the housing. As the angle increases, the top 4 balls begin to slide out of the housing, (like they are supposed to do) to maintain constant torque. as the top 4 balls slide out of the housing the lower 4 go in further (no big deal) but the problem with this is that the top 4 start to come out so far that bu the time the joint is at MAX flex, the top 4 balls are only in the housing about 1/16th of an inch!!! Now keep in mind, this all happens as its ROTATING so the balls wil also slide in and out at the same time, so each ball will almost fall out of the housing at some point in the rotation. Will it work on the street??? YES. For how long? It depends on how you drive. Will it survive on a trail???? NEVER. there will only be torque transmitted to the lower 4 balls at any given time. Will the 2 door be worse than the 4 door??? Yes. The angles are greater on the 2 door than the 4 door, but ANY lift on a JK will cause a degree of weakness in the Rzeppa joint. I am picking up my drivelines tomorrow, so I will grab the old one and try to get some pics up for those that cant quite picture what I am talking about. Comparing these joints to the ones used on the high horsepower imports is like apples and oranges. They operate at a zero angle, therefore are VERY VERY strong, like thee would be if we could leave them STOCK.....:D
