Do a search. I'm sure I've seen this asked before here - I "think" you can but, not sure? I'd "guess" (since it's not my truck - I can afford to do so:-laf ) you can do one at a time making sure you torque the stud, then torque the nut, then re torque all after they are all in. I'm willing to bet that the stud isn't long enough to properly torque it with the head in the way but, I could be wrong???
But, like I said I'd check first, as I can afford to guess since it's your truck - sorry just in a strange mood this am.
All kiddin aside - Definitly do a search first - then ask if others have done what you propose and how they have made out - long term.
Happy bombing!!!
