Ok, the right-rear wheel squeeks!!, and it's driving me crazy. I replaced the brakepads and had the disk/rotor shaked....and its still squeeks!! WTF...why, its freaking annoying..and what sucks is I dont even have 7 months with the truck...i bought my truck brand-spanking new with 0 miles on it....and it ****ing squeeks!!!!! why....

 

When does it squeak? When it's rotating or when you are going over bumps? If it's doing it while rotating you were right to start with the brakes. You can also lift the rear end up and try rotating the wheels to see where the squeak is coming from. It could be wheel bearings. If it's when you are going over bumps, check to make sure your suspension is tight. My old Dakota squeaked a lot, and although I never got it fixed, I was pretty sure it was too much play in where the shocks mounted to the frame.
