Hey Chad,
I am sure you remember my strange noise that was coming from my Jeep. And after long inspection from me, you told me my front drive shaft was dragging... oops 
Well after a new u-joint sheared on the 101 at 70mph I knew that something else was wrong. I removed the front drive shaft and after inspection discovered it was bent. Makes sense as to the problem with the joint huh.
I ordered a new drive shaft through my mechanic ($170 complete the DS joints). When going to install I had one hell of a time trying to figure out why the clip would not snap in on the one side of the yoke - remember I had this problem on the trail too.
Anyways, aside from a bent drive shave, the notch on one side of the yoke was missing which holds the joint in place. I guess there is one on each side.
A new front yoke and everything is a-ok.
One other thing, you were right about Desert Rat not installing a spacer in the yoke slip eliminator. I guess a piece of aluminum can would have saved my garage floor from the constant gear oil drip. The slack inside the unit caused the seal to fail prematurely.
Just thought I would give an update and thank you for the advise on the yoke slip.
See you on the trail.
Ryan
