    i'm gonna attempt to replace the half shafts on my 2000 gmc 3/4 ton sierra cc this weekend. i have been hearing a considerable amount of clicking up there in 4 wheel and i also notice some clunking when shifting from forward to reverse which is probably a u joint right? anyway is there any special tools required to replacing the half shafts? how much of a pita is it? how long? what about replacing the u joint up there as well? anybody ever done this themselves? i'm really not that mechanically inclined. any help is greatly appreciated!

    Half shafts are really easy to change. You will need a big socket to remove the spindle nut most likely a 36mm. Then you will need to remove the bolts that hold the shaft onto the differential those are most likely 15mm. I needed to remove the sway bar end link for clearance. then you just drop it down from the diff and slide it out towards the center of the truck. One side took me 1/2 hour and it was my first time doing it.

    Abes is right, on the 3/4 ton you should be able to squeak it through the inside, i think the 1/2 tons dont have that clearance and you end up seperating ball joints..
