C6 Doberman

I know the feeling. I have had a few bad experiences with trucks. Each a different brand. We want to trash the entire line of trucks when we have a bad one. There are other Sierra and Silverado's that will never have a problem.

Care to elaborate on the Sierra being a piece of crap? Every manufacturer has problems. That is part of mass production. There is no such thing as zero defects.

I get the same noise from the drivers side front. I only notice it at 60-70 mph. I drove another truck on the dealers lot and it made the same sound.

Looks great! Do you have pics of the fox shocks?

Looks good. Almost need to find an adjustable angle bracket to fine tune the light.

Sweet! Now you can make vampires burst into flames.

And den?

They are pretty awesome! I took it in because I was having some vibration issues at 70 mph(more than there should be). They replaced all 4 tires(35x12.50x20) and fixed the problem. They also gave me a 2013 Yukon Denali for a loaner. Thing only had 10 miles on it!! As a bonus they have a theatre with like a 100+" screen in the waiting room!!!!!

The Dealership installed everything on my truck and I have a signed document stating that they will still stand behind factory warranty.

My truck is lifted and I have the same sound when in Auto 4WD. I have tested mine and it does work. Tried climbing over a few obstacles this past weekend and as soon as the back tires loose traction the front kicks in. Pretty cool. It is very loud though when at driving speed. Curious to see what your dealer says. Keep us updated.

Sweet! Have you lit it up yet?

I'm curious as well. I'm not sure if it is a tire. My truck has a horrible vibration now at anything over 60 mph. I have a 6" lift with 35" tires. Had one tire replaced and balanced several times to no Avail. It feels like something in the front of the truck but I can feel it in the steering wheel and the seat. Hell, I can feel it in the floor sometimes. Going to see if I can get the dealer to swap the pro comp tires for some toyo open country just to eliminate one variable.
