Need Help on Ford F150

I have a 2005 f150 that has developed a howl in the rear end I have taken it to the dealer he informs me there is a service bullitin on my truck that defines the problem as a ring and pinion failure and will also need new bearings and cups ,however the trusk went out of faactory warranty 4 months ago and ford will not help even with the 31000 mile on this truck .It would appear there is a vendor problem and I feel justice should be served .The dealer has offered to chip in however I dont feel it is there place to have to do that .
I am wonderig if anyone an has email address for the CEO Alan Mulally of ford motor company or any telephone numbers or just a suggeston as what to do .
Don

just write to Ford motor co. Dearborn, Michigan. I doubt your letter would get through to the CEO of Ford. You can get the exact address and zip code upon searching the web. Now that I think of it you could search the web and perhaps find a solution that you were not aware of.
