09 2500 6.7L CTD 4x4, Auto, shortbox SXT

Today on I-80 cruising about 80 mph, I started hearing a thumping sound on my driver side front, pulled off, and found the wheel well liner had cracked and basically been taken apart by my tire the way a circular saw would go through a 2x4. The noise was from the remainder of the liner hanging down, hitting my tire. I checked the other side, and sure enough, it doesn't look like long before that one goes as well. Are these warrantied? I have hit some pot holes and definitely had some articulation in the 12,000 miles I have, but nothing to warrant this kind of destruction to the plastic!

Secondly, and it started to get real bad today, I have the most annoying squeak coming from my transfer case shifter. When I isolated the sound finally, I applied a little pressure with my hand on the ****, and the sound went away. Any ideas, maybe just loose?

Thanks in advance for any comments, suggestions.

 

my left rear wheel well plastic was hanging bolts fell out of it had to replace it with a new one after my tires ate it up
