I replaced king pin bearings on FG649 which required removal of drive shaft. One person, roadside. Hardest part was remembering the sequence of springs in the free wheel hub. A piece of pipe approx 42mmID, 49mmOD x 300mm long was useful for removing / replacing king pin bearing outer shells but not required for drive shaft removal. A bit tight removing / replacing the drive shaft. One of those "its easy once you've done it" jobs. I replaced the inner oil seal (for drive shaft) as a matter of course. A bit of #8 wire to hold brake back plate out of the way without stretching flexible pipe. There's a couple of "liquid" gasket materials and a heap of grease. All just as the manual described. I didn't look too closely at my CV joint. I have some reasonable pics if you need.
