Hello everyone! Thinking about picking up this Denali. I read the sticky " Thinking of buying" and it said "Awd Front diffs like to eat themshelf" What do I look for? How do you know if it's going out? Also how is the reliability on these SUV's? What else should I look out for? other problems with them? link to SUV http://nashville.craigslist.org/ctd/5502767033.html
Thanks for the help
