Wondering if somebody could please help explain my warranty for me since my dealer is a complete nimrod. I recently had a left front wheel bearing go out and was told that it is not warranted at my 50,000 mile juncture in a 05 Cummins. I was under the impression the powertrain was warranted to 70,000 miles, I was also never told about the $100 deductable until recently as well. My real question is, is there anything else I should know about this warranty, when should I check certain parts ect... for problems before these goofy side warranties go out. thanks for the help in advance.
