You should see what a rock crawler goes thru with the diffs locked!
Tires scuffing and binding is not a problem as they will slip. Far less strain, then running over a rock and binding. The hardest part is going to be getting it out of 4lo and back into high gear. Drive straight, and back up if needed. You can gently let the clutch out in neutral, wait a second and ease it into a high gear. Turning the front wheels back and forth will also help unload the driveline.
