Is it very difficult to change half shafts? Book shows tearing most of front end off. lol. I should change them before Turkey season this year. Truck gets a lot of mud slung under it during the season. I am not a big fan of working on underside. To much grime a frozen fasteners from rust.

If the boots aren't torn, they shouldn't need to be replaced. They are not difficult to do, they are just different.

Boots have big tears in them on both ends, so they need changed.I just ave never done it before.
