Basically my thoughts as well. But I'd still like to have them :tard:Good point on the angular capacity of the RCVs vs. stock half-axle assemblies ... that's an aspect I hadn't actually considered yet; and certainly bears some thought. It may be that the argument for RCVs lies there ... however, I think (for the purposes of the Xterra) claiming that these are necessary purely for their strength, is a bit of red herring ... yes, they will be (much) stronger than stock. But is that really necessary? I'd argue not.
For a truck with a SFA, where you'd have to tear down the front hub and pull out either side shaft, were one of the steering joints (or either shaft) to fail ... or put another way, where the whole side shaft is effectively inside the axle ... then I agree, you want to put as much strength internal to the assembly as you can (and as your wallet can tolerate); with the goal being to put the weakest link someplace external to the axle - like the front DS u-joints.
On the Nissan IFS, a halfshaft swap is relatively easily done ... and at ~$100 (or less) for a trail spare, there's a fair amount of wheeling that can be done before I'd consider socking away $2k for RCV assemblies. I think that dichotomy is further compounded when the diff internals are beefed up ... if you've done that (with an ARB or a lunchbox locker); then with these RCVs, I'd think you're looking at the next weak link either being one of the front hub assemblies, or perhaps the diff-internal side-shaft.
Am I missing something?
