RE: stampede with diff lube = slower?
the 50k is probally leaking out causing it to stick to the gears and slow everything up, cuz i don't think those diffs are sealed so you ran run most greases fine cuz they wont' leak out or if they do they're only like 3k oil so its not big deal, but 50k is gunna slow things up and its way more sticky
