Yes the computer would freak out something fierce if you pulled the front DS. Ok I thought it only happened in 4LO never mind onto a different part then. I'm going to throw my money at the actual CV joint on either end of the half shaft. If it only happens on rough terrain then that would make sense since its the half shaft thats doing all the moving around putting the CV joints at high angles. If one of them is bad or say lost all it's grease it would be upset about being flexed around.
