How to change the front drive shaft u-joints on a 1986 F-250?

It is indepent suspension front end. Both u-joints are needed to be replaced.|||Best bet is a repair manual as if gives you a step by step directions and pictures , not a bad deal for $20 . But below is Autozones directions with a few exploded views. Changing the u joints is easy , getting the shafts out is another story . good luck and be prepared to spend a few hrs on it.
