A body 8-3/4 axles

I consdiered getting some C-bod axles cut and splined when I built the rear for my Duster. A guy at a driveline shop I use told me it was not a good idea if you plan on making much power, because as Suregrip mentions, the heat created in the process will soften them up to some degree. It just depends on how good they are at doing it. But he said it was not uncommon for them to get complaints from people who had re-splined some axles that ended up getting twisted right off. So I decided to go with new Yukons.
