That doesn't sound like a cv joint. Sounds more like suspension. In order to service the halfshafts, the steering knuckle needs to be removed. Perhaps the lower ball joint isn't lined up correctly, or tie-rod end, or your struts were torqued too much. All of that stuff needs to be loosend to take the knuckle off. My advice, suspend the front end, take both wheels off, and see if you can jiggle any of those parts. If so, bingo. If not, the spindles on the shafts aren't seated right or have bad retainers. Good luck and hope it works out!
