Man oh man its one of those days.  SO for a while ive had a slight vibration when accelerating from a stop light, i know its probibly a u joint needing some grease or on its way out.  So last night the truck drove fine all the way home.  Woke up this morning and was going to grease my driveshaft.  My grease gun needed new grease so i was changing it out, and the end with the plunger with the spring, shot out and took out my two middle fingers when i was screwing the other end together, they swelled up and i was bleeding all over.  A few round house kicks to the bed of my truck later i decided this was a sign and wrapped it up.  Spent all morning icing my hand, and then headed off to work.  My truck started shaking violently all the way up to 60mph when i was on the gas.  Figures the trucks getting back at me for kicking it lol!!  Keep in mind 13hrs and 0 miles ealier it was driving fine.  So i limp it to work (30mile drive up 55 to midway) and hope under and one of my rear driveshaft u joints is puking its guts out.  So now im going to have to drop my rear driveshaft tonight at about 10pm, drive to new lenox to use my buddies press and swap the shaft back in.  Looks like ill be burning the midnight oil.  Thanks for reading, man its one of those days lol.

Feel free to post up you similar stories!!! 

Got it all finished at 130am this morning. I was missing all my needle bearings under one of the ujoint caps on my rear driveshaft.  MAke sure you grease your stuff, because it will break at the most incovienent times.  Im just glad it didnt manifest itself at the cliffs and or break there.

When greasing u-joints make certain all four caps show grease pushing out. I just had two on my truck go out and 3 of the four caps were all greased up, the fourth was all dried up.

slander make sure you grease the new joint, the grease in it when new is only there for packaging not long term use. Don't ask how I know this.

Ggg- All over it and greased up.  Im pretty good about greasing stuff up, the joint that went out the grease zerk is impossible to get to on the truck, in order to reach it you need to pop the shaft off.  I put that off for two years and it came back to bite me.

Stinkymud- wow that sucks!  BUT you can replace that u joint for about 15 bucks.  Just get a new u joint and press it out on a bnch vice, or you can even use a socket to get the u joint out.  DO NOT pay someone to do that, changing a u joint is sometheing evrey wheeler needs to know, because thats what commonly breaks on the front end, and its considerd a wear item. 

This site is extemely useful for any jeep project you need to do, this is the site i used to learn how to alot of the mods and mantenence on my previous jeep http://www.stu-offroad.com/index.asp.  He has a real good write up on how to change out u joints amongst many many many others!!!

Stu's site does rock!!  I forgot about the fun of changing out a jeep axle ujoint, i actually got to the point where they were easy to change because i would just shear the ears off the yoke evrey trip out lol, the u joint just falls out then!
