FYI, when I did my research a year ago, I came to the conclusion that Moser front axles were not nearly as good as Warns. (I have Moser rear axles and agree that they're probably the best for that application.) What I found is that they were having breakage problems on front axles at the u-joint saddle. I have heard that they have recently redesigned that area of their front shafts, so that problem may not exist any more.
I've run Moser rear and Warn front shafts for a year now, with 36" Swampers, doing lots of hard core rock crawling, and I have not had any problems at all with any axle shafts.
