52,000 miles on '11. I noticed a rear end whine under power. Especially @ 60 mph. Dealer says probably pinion bearing. I thought these were upgraded 2011+? My 2004 went 2-3 times over the 225,000+ miles I drove it.
Frustrating!

 

I made my GF ride in the bed the other night and was getting a terrible whine thru the back window.

Then I closed it and all was well. (Cept for when we got home)

 

Lol

 

 

2011 with 52k is still under powertrain warranty, you should be able to get it fixed free.

 

Hey Power Kid, How is your 2011 running otherwise?
Did you ever go in for any of those EB TSB's or the new intercooler?

Is the pinion bearing included in this?
