LJ / Rubicon U-Joints

I have a 2005 Jeep Rubicon Unlimited (LJ Rubicon)... I'm replacing all of my U-Joints...

According to Jerry Bransford, Spicer & Denny's... The Spicer NON-Greasable U-Joints "should be"...

Front Driveshaft @ Pinion: 5-793x
Front Driveshaft @ CV: 5-1330x (edit: 5-790x is now obsolete)
Front Driveshaft @ T-Case: 5-1330x (edit: 5-790x is now obsolete)
CV Centering Yoke: 211996X

LJ Rubicon w/ Rear Driveshaft #585AA @ T-Case: 5-1330x
LJ Rubicon w/ Rear Driveshaft #585AA @ Pinion: 5-1330x


Spicer's site is out of date. They incorrectly show the "Obsolete" 5-790x for the Front DS @ CV & T-Case.


Denny's lists a pair of Spicer 5-1330x U-Joints as the correct joints for the Front DS @ CV & T-Case.



Can anyone "first hand" confirm this? I've read so many conflicting reports on the Rear Driveshaft U-Joints when it comes specifically to the Unlimited Rubicon LJ.....

For the LJ Rubicon with stock driveline, the correct joints for both ends of the rear driveshaft are 5-790x (which are obsolete, replaced by the 5-1330x). Front DS and axle joints you have listed are correct.

Mukluk is correct. When did jerry post that information? I'm guessing it's a couple years old because until recently there was a ton of confusion with the LJ rear DS ujoints even if you called Spicer themselves.

Muchas gracias! That makes so much sense now. I spent way too long scratching my head trying to figure that out.

My references were sited above in the 1st post. I referenced Jerry (circa 2013), Spicer's website and Denny's.

Even embedded the links.

I can however "not" confirm the TJ Rubicon Info... so I will remove it as I have a Rubi LJ.

Oops sorry didn't realize you were the OP when you posted that second chart. This has caused a lot of headaches for many different people just because there is so much contradictory info out there

Yeah, it was from Jerry about 2 years ago.

I've read that forum, but man... it's the only source I've found that says Spicer 5-1330x's for the rear instead of the 1310's... Does he have some sort of factory whoopsie going on for his rear driveshaft..?

I'd assume it'd be all over the Forum / Internet by now if every single dude who owns a Rubicon LJ went to go change out his rear U-Joints and realized that he didn't order the right ones.....

There has been a lot of confusion on the right Rubicon driveshaft u-joints since they changed between 2003 and 2004. I am no longer able to provide the correct part numbers for the Rubicon since a computer crash a few years ago wiped that information out. I've been as confused as anyone since then. My 2004 Rubicon doesn't run stock size driveshaft u-joints so I can't even look at my spares to know what a stock Rubicon runs.

When you have a choice, buy American made.

Stock rear driveshaft does only have 2 u-joints.

You have something that is not stock.
