Hmm, really don't agree with that. I have no clue how engaging 4wd would cause that type of issue, or how a bad diff could do that???So they are saying front diff is toast and “engaging 4x4 is what pushed the CV apart”apparently. Leaving a bad taste in my mouth here.
While there is no reason to remove the CV shaft when doing the wheel hub, there is a reasonable chance it got pulled out from the diff when they did the work. The other end of the CV splines into the wheel hub. If the splines were slightly stuck inside the hub, which is not uncommon, and they just yanked the hub off it could pull the CV shaft out/off of the diff and disengaged the snap ring. Then if they didn't "pop" the shaft back to re-engage the snap ring something like this could happen.
