Wasnt a difficult change, took about an hour and a half.. air wrench and a torch help tons. I ended up getting the greaseable u-joints, my buddy told me as long as i keep greasing them every oil change I shouldnt have the same problem. 40K and the stocks ones were shot. Since the rear was so bad I just change the front one too $13 a piece, it was starting to get stiff(rear drive shaft)... next up is my steering rack. Napa surprisingly has the best prices, $183. and core charge...
