So just this past week I bought a 1999 Chevy Suburban LS 4x4 5.7. I love it so far, but while searching for common issues and pattern failures to look out for, I found that the NP246 transfer case that the truck is equipped with has a tendency to fail because of pump rub which causes a pinhole in the transfer case. My suburban has not experienced this yet despite having a few leaks around the tails shaft and the speed sensor. Has anyone experienced this? The truck has 160k miles on it and has been well maintained for the most part. Should I be worried about this failing? I bought the truck to be my daily driver, reliable, get-anywhere type vehicle for the next few years, so I hate hearing that it may need an expensive component to keep it on the road especially being that I bought it so recently. Any thoughts?
