Rear axle tick

[lowreese26]

hey guys.
I asked this question in the stupid axle questions sticky, but no replies.
I am going out of town for father's day, and would like to get the Yukon running perfect.
The only problem I can't seem to figure out is the ticking in the rear axle.
Any ideas guys?
Thanks for the help.

I would first pull the drums off and inspect the brakes, next would thing to check would be the u-joints.
