Found the cause of the clicking noise...

...from the rear of my Z and it wasn't the u-joints, spindle washer, or lack of lube on the spindle. The leaf spring end bushings were toast...looked ok on the outside, but there was a whole lotta nothing in the center as the bolt was nice and shiny from flopping around on the leaf spring and knuckle eyelet....poly bushings are going in this time. The u-joints look ok but i'm going to replace `em anyway since I've got it apart.

Good deal Steve. Be sure to check the rest of your bushings.

Thanks for your help Jeff...most of the other bushings look pretty good...but as I found out you can't always tell just by looking. I'll be checking things out a little closer tonight as I wipe some of the road grime off of everything and clean it up back there.
