Look, use anti-seize or don't use anti-seize it probably won't make a difference if you get your press right. I'm not in a dick measuring competition with any of you and I'm not going to die on this hill. This is what I hate about forums, you try to be helpful and give an opinion and the gang jumps in on you. I have some machinists in my family, and we've had this discussion a number of times. Any press fittings will eventually wear out. That is a fact, and you don't have to have a degree in engineering to google search that. The likelihood of it happening over lifespan of an axle would depend on a lot of factors. If you get your presses right the tolerances will allow that axle to last for a long time and will likely not be the determinate factor in that vehicle ending up in the recycle pile. Press enough fittings into it over time and or gouge it doing it incorrectly and the metal will wear improperly causing premature failure. Has it happened to you and you do it all of the time? No? well maybe you know what you're doing and you buy good quality products. Have press fittings failed? yes they have. With computerized machining these days Dana is getting tolerances closer to .001 to .002 so they are incredibly tight. Is there a magic number of how many times it takes to wear it out? The answer is no because there is to many variables. My entire point is to take the conservative approach for safety by reducing the likelihood of premature failure by not wearing it out to begin with. You do you Eddie/WJCO
