Yes, use blue Loctite (not red).
Ford doesn't spec Loctite because they tell you to replace the nut with a new one (which is already locking). They will also tell you that if you do reuse the nut, you should use Loctite.
The short answer is that everything on the suspension and driveline gets blue Loctite unless there is a specific reason to do otherwise. And that is not going to cause any problem at all for removal later.
