Typically the most economical thing to do is buy a complete remanufactured axle(s). When you buy individual joints and boots, the collective cost is usually the same or more than a complete remanufactured axle.

You are probably right. My 911 is from 1973, so a long time for that grease to degrade.
And I do prefer to buy the complete axle, so much easier.
