i had an 06' that would make some steering noise once in a while i had to bring it back three or four times then they figured out that it was the skid plate making noise when the frame would flex during steering. solution was drop the skid plate and put rubber grommits in between the skid plate...
mine were leaking with 38k or so and the dealer claimed they werent going to replace them under warranty either. i hounded them a little bit told them i did some research online and others were getting them covered under the power train warranty then they replaced them.
im not going to lie they did do the day that i went to talk to them. idk... the service manager seeings how im over on my milage it would have to get covered under the powertrain warranty... he said they are a little more strict with that.
