The only guarantee you have with Dynatrac is that you're going to rebuild it someday.
Yes, this is true. I'm sure someday I'll have to re-build the Dynatrac lower ball joints and hopefully, it'll be more than 10K miles. I guarantee you that I'll be the first one to report on the mileage that I've gotten out of them and will probably give my opinion on them just as I've done with Carli's.
Sage and his business appear to have gone all out to correct/remedy the issues with their first generation lowers. We, as consumers (especially in this economy) definately appreciate this.
I chose to try a different manufacturer because my personal confidence in Carli lowers doesn't exist AT THIS TIME. Maybe, after a year or two, my opinion will change. I'd like to see several customers out there in all parts of the country/world use their product and not have any drivability issues.
You say that your second generation joint is made from better metals and that the hardening process is improved beyond any doubt because of the California State University lab tables. This is all fine and well, but I'm going to interject some common sense: The cup/ball is metal on metal with a thin film of grease on it that will go to the top/bottom of the ball, reducing the joint to being just metal on metal.
Question 1): Do you know of any other product out there that's metal on metal, being subjected to about 5K lbs of pressure (give/take depending on if it's status or not) daily on an array of different conditions? If so, what is that product and what type of metal is it made of? I can't think of anything offhand. Most parts that have metal/metal contact has some sort of bearing between them, or some sort of sleeve.
Question 2): Are you saying that because the metals are so hard and smooth, have gone through a superior hardening process that there won't be any wear on the mating surfaces?
These are just curiosity questions that others out there may have. Those that have followed these threads are on the fence and will purchase something and are willing to part with alot of hard earned money to attempt to fix a problem that AAM should have never allowed to begin with.
Plus, I almost stayed out of this thread because I didn't want to appear to be bashing anyone or to start a brand war. This is far from my intent as I'm just sharing my experiences/views.
