1,100 miles into owning our new 2007 silverado, a loud clunk was heard pulled over to find the left rear axle shooting oil and smoking like crazy. The vehicle had to be towed back to the dealership. 10 days later and over 8 hours of work the rear axle was rebuilt. Unclear as to why. . . Still working on that issue.
