Just got my truck back from dealer .They replaced the front rotors (for the second time).They also discovered the front differential was leaking and replaced the seal. Both repairs were covered under warranty. The rear axle was replaced about 10 months ago. I bought the truck used last year with 33,000 miles on it and Im now at 38,000. I like the truck alot, but I am starting to think I may have made a mistake. Has anyone had a similar amount of problems?
