Messy job. Here is what I would do, have done.
Remove both axles with the CV joints. Mark the direction of forward rotation on the axles. They have been stressed primarily in one direction, so we don't want to reverse that. Also mark the direction of forward rotation on each CV joint. This will come in handy in one scenario.
Disassemble the CV joints keeping all the parts together so you don't mix CV components and keep track of the orientation of the inner and outer bearing and cage. Clean everything thoroughly. You will see wear on the inner and outer bearing surfaces and some on the ball cage as well.
Depending on the wear, you have a few options. If it is really bad, replace the CV joint(s). If the wear heavy on one side and light on the other, reassemble the CV joint and reinstall it on the opposite side of the car so the forward rotation is the reverse of what it was. (This takes the load off the worn bearing side and places it on the less worn side.) The third scenario is little wear every where. In that case, reassemble and repack the CV joints and put it all back together the way it was.
Here the one shot I could find from the last time I did this job on my 911. You can clearly see the wear on the inner bearing surface.
