My pinion nut appears to have backed off as there is oil splattered all over my rear end. My truck goes in tomorrow to have the exhaust manifold replaced, and I'll have them look at the rear end as well. I still have a dealer warranty as I am the 2cnd owner of the truck, no lifetime power train warranty. I also filed a complaint on the website provided, ALL 2009 and 2010's should be affected by this recall. My build date is 1/09, and currently not included. here is a link to my pictures.
