I recently lowered my 98 sierra to 3" front & 4" back. the front is lower
than the front. I lowered it with a lowering kit that it was special made
for 4wd. But after a couple days i started to notice a sound coming out
of the front, only when the 4wd is on. i can only hear it when am going
like around 30 to 40 mph, and when am not pressing the gas. I think is
getting louder but am not sure. If any one know what it might be
please help me...
