Well I know many people have questioned longevity with upgraded birfs with the softer heat treating in a Fulltime 4wd truck. I had heard Bobby Long say they are good for 60,000 miles. I didn't think anything of it since at the time I was maybe driving my truck 5-8000 miles a year. Fast Forward to 4 years later, 2 trips across the country north to south and two trips across the country east to west a lot of daily driving and somewhere around 50,000ish miles. I have sprung a leak that I would guess is due to the seal wearing into the softer metal of the shaft.
Just an FYI for those of us using our trucks to sight see malls more than wheel you could save a little money on the RCV 300m superset. lol.
