question regarding cv boot change

[j.fro]

1) I do not believe the factory used loctite, but if the car had a previous owner, the bolts may have been removed for one thing or another, and loctite may have been used. The last car that I did the CV boot replacement on had loctite on everything. I have seen other cars that did not have it.
2) An impact wrench shouldn't hurt, and is a good alternative for stuck bolts. You might also try heating the bolts using a Mapp gas torch.
3) the inner joint is the easy one to check for scoring. You'll need to remove the joint to get the boots anyway, so disassembly isn't too much more work. Chances are it's OK...those things are tough.
