I know a bunch of guys running welded 14 bolts with no issue other then accelerated tire wear and hazerdous driving on heavy rain and ice!. Locked or weleded axles make a huge difference on the trail. They are not the same tho. I run a front locker (lockright). On the trail you can not even feel it but man does it make a difference. Unlike a welded diff it can rachet when not on the gas which helps keep a tight turning radius. On the street I Don't use the front axle so no problems. As stated weld is perment all the time traction with no differential action. I would only weld the rear on a road diven truck and put a lockright or aussie in the font if it needed to be done on the cheap. If it is trail only then weld weld would be OK.
