I am reviving this thread to report that my GSP has held up so far, but it has not seen that much use/abuse. It's been off road only a handful of times, lots of road miles as well. The install, for a first timer, went smooth. However, my passenger side original CV has been leaking, and I'm back at the cross roads of which CV to buy. Napa does not stock the Altrom brand that was supposed to be OEM repackaged, and I can't find Altrom as being carried anywhere else. With a trip to Big Bend Ranch coming up, I want to be squared away before hitting the road. Any new info or reports, good or bad, on CV axle replacements?
