Also, I had the same situation and I went ahead and put the lockwrong up front (and longfields) and welded the rear. Only real PIA is in tight turns respective to tire wear and surmounting obstacles (BIRFIELDS!!) with harsh turn angle demands. From what I read and heard, its a deal where if you can't/won't buy airlockers or selectable lockers and its a trail rig mostly, weld it.
