So a few days ago, I noticed my 2012 F150 making a whirring noise while driving. Almost like I had mud tires on it but not quite that bad. I rotated the tires thinking they were getting cupped but that didn't change anything. Tonight I put the rear end on jack stands, started it up and put it in gear. After disabling traction control so I could actually get the rear tires to spin I immediately started hearing the noise. Sounds like it is coming from the rear end or tranny. I am taking it to the dealer as soon as I can but just curious if anyone else had experienced this?

 

Got my truck back today. 2 months ago I had the TSB done on the rearend to cure the "click" noise when shifting from P to D or R. Apparently the techs were idiots because they screwed up all up when they reassembled it. I took it to another dealer this time and they ended up replacing everything in the rear end.
