I first noticed that when i would accelerate gently that i would get a squeak squeak squeak. when i torqed it, it went away. Now i will be driving on the highway and when i accelerate, i can hear a constant squeal. the only suspension mod i have is a 2" rear drop. I have no clue what it is, but it is VERY annoying. i am getting ready to go cross country with my truck and i don't want it breaking on me.

ask any questions you need to. I want to get this fixed.

 

Check your U joints. Changing the rear end geometry by lifting or lowering will cause them to fail maybe a little quicker than they normally would. That's where I would start.

Good Luck.
