The CV boot failure was remedied after the trip when we installed a new one at RED. So, did the IFS fail? Well, it worked as good off-road as a solid axle. It flexed, it crawled, and it ran down the road. The parts did come apart, so that is a negative, but they all could have been repaired on the trail. Basically we’ll give it a solid B . We had hoped for zero issues; we got two. As minor and preventable as they were, they were still inconvenient.
