Good luck with the AutoZone axles. I bought a set for my Pathfinder and it was missing the outer CV joint. The set I ordered for my Saab neve arrived at the store. I guess I was lucky.

Unless your boots are already torn and your joints are worn, it's still a better deal to have the boots replaced. The surfaces within the axle are hardened; when they are rebuilt they are ground down to un-hardened metal.
