As it turns out, replacing CV boot was a pain only because I could not get half shaft removed.
Having removed the 12 inside/outside bolts, the inside end of the half shaft came right off the ZF. However, I must have done a pretty good job sealing the outside end of the half shaft to the carrier with gray rtv.
Am sure outside CV will go at sometine just looking at it, any ideas on how best to break the seal between the outside half shaft and the carrier?
