I think you might have already figured this out. But the VC does not make it full time or part time. I dont think VC or no VC is a big deal. But if you were part time I would run the softer stronger axles in heartbeat. My truck is part time now but I have been doing less wheeling and more traveling. So unless I need to replace birfields I wont spend the money on aftermarket ones. But if I had a set it would be nice.
In hind sight I dont really think the cost of going part time was worth it to me. But it does let you get creative in a build. If i wanted to do a big lift i wouldn't have to worry about front drive line vibe. Also i just replaced spindles. If my old ones were still good i wouldn't care about the bushing vs needle bearings. But mostly I can run any birfield /axle I want and not really care about wear from milage.
