I've got the LSD in mine front and rear. I drove mine with only one hub locked in since I've got manuals on mine. Did the pass front since drivers rear seem to be he main power ( least it seemed like to me). Did better then with both hubs locked in.
Did the whole front end when I did my diff and painted all pretty. Then slapped the skid plate on and went "well that was a waste of time". Still it's pretty. Moved my diff vent higher and used a lot of stainless steel bolts on it. Salty roads here.
