Hey Guys,
I am getting a very strange metal on metal sound from my rear end while driving on the highway. I have had my 3" lift on now for about 2 months, but this sound has just started over the past couple of weeks. It never happens when I hit a bump, or when I am driving below forty. it seems to be worse in the 60mph range and gets a little better above that. the sound is just a quick metal on metal bump or grind. it has noting to do with acceleration or braking, as I only hear it when i am on a smooth road and maintaining speed. I live atop lookout mountain and I have noticed that I hear it going down the mountain above 40 but never coming up the mountain at speeds above 40.
I have checked all the installed lift items to make sure they are tight and cant find a problem, dont see any worn bushings or rub spots. I cannot hear the sound when bouncing up and down on the bumper.
I wonder about kdss since it stiffens at higher speeds, but i cant imagine why i would hear anything on a smooth road instead of on bumps.
I have 160k on my truck so it could be wear on something, anybody ever have an issue like this?
thanks!
