Since lifting the Libby, I noticed a slight vibration from rear train when applying throttle from complete stop, lasts about 2-3 sec then it's gone. I suspect the u-joint to be put under more stress caused by differential standing lower. Besides, should be a good idea to replace them, as part of regular maintenance.

My problem now stands with ordering them... Rockauto offers a wide choice, but I am a bit mesmerized by the part description, where it mentions: "Exc. Man. Shift-On-The-Fly Transfer Case"

Aren't all KJ equipped with manual shift-on-the-fly transfer case? Why the exception, then? Does not make any sense

Hey hey you again,i changed mine 1 month ago,since the !%!$ dealership change only one and it broke right away because of the other one seized up,so i went with
precision super strenght greasable number 280,two of them,21$ each,you grease them every 5000km,you will never have any problems.

If you want non-greasable you can go with super strenght number 269.

For sure some here will say go with the spicer ones,you can get them for around 30$ each,but my precision ones are more than enough,and they handle our torque easily.

By the way both u-joint are the same on our crd,so dont worry,i did so many checks about that,the numbers i gave you are the good ones, i measured them,and even talked to the fed mogul guy

Your local parts store should carry them,they are from federal mogul,and one advice,CHANGE BOTH!!!

Stealership Would not trust them any farther than where I could throw them...

BTW, thx for the numbers. I did call Fed Mogul and the tech was quite surprised about my query, actually mentioned this was the first time someone called him with this question (shift-on-the-fly thing). He was only able to tell me the recommended part # (all 369 or 369/354 combo)...

Since you've had first-hand experience with this, I'll follow your advice... Thx again!
