Diff lock on the 2016 TRD OR

so are you implying those are the two rules if you have Air Lockers...Don't turn while using them, and don't use them downhill?

 

I wouldn't say its a rule...but probably not a smart idea.
Remember when you have your wheels locked they are turning at the same speed. Try and steer with locked wheels and one will want to move slower than the other. It will basically be a fight between traction and your gears. IFS diffs aren't built as strong as solid axle diff, so its going to cause problems...besides while going downhill I wouldn't want to lose my steering, with a front diff locked you wont really have much steering and if you try to turn to avoid hitting something, you're probably going to start to slide right into it. I mean, if you're into that kinda thing like wrecking your truck and crashing, by all means do it
