Hey gang, had to do the walk (trailer) of shame home tonight. The ujoint closest to the t-case started coming apart and I had to abandon the Jeep in a parking lot. I didn't have a wrench small enough or a socket extension long enough to pull the driveshaft out in the parking lot so on the trailer it went.

What ujoints am I looking for for the front driveshaft? I'm going to replace all 3? of them. Is the Rubicon front any different than a non Rubicon?

Spicer 5-1330x for the front driveshaft's two rear most u-joints in the CV joint next to the transfer case. You need an 8mm box end wrench to remove the strap that holds the u-joint into the yoke.

Too late, Amazon buy now is too speedy. This is purely a toy, it only sees 3000 miles a year at most.
 
Unless they have been changed in the recent past, assume your joints may all be the same age and check/test them all. Even the ones in the front axles. Very nice trailer.
 
Are these something that should be changed depending on miles or just age now that my Rubi is 15 years old but only 40k miles
 
Ok thanks good to know, I just like to be proactive when needed. I never want to be THAT GUY on the trails that brakes down when everyone else knows your U-joints should be replaced every so many miles.
 
Is it possible to confuse the U-joints and on the front and rear shafts or do they simply not fit if you have them wrong
 
Guess I need to pull the driveshaft out before ordering. I can't tell if the cv is greasable or not and they are different kit numbers.
 
Another way to think about greaseable vs non-greaseable is why do most u-joints fail? 99% of u-joint failure is caused by a lack of u-joint lubrication, like in OP case. All sealed u-joints will fail at some point do the lack of lubrication. Where a greaseable u-joint has the potential to last for ever if lubricate correctly. U-joint center failure is usually caused by the users application exceeding the design u-joint deflection or at near limit deflection and high torque loads like found at the knuckles.
