i got my ground controls and koni yellows installed about 8 mons ago and they have been squeaking in the back whenever i go over a bump and the back end bounces for like 2 mons now at first it was tolerable but now i cant stand it. the front end squeaks too but not as bad, cause it doesnt bounce as much. i asked about it a while back and was told to lubricate the bushing on top of my springs, i did that but i didnt get rid of it. i noticed the other night that when it rained outside the squeak was gone, so im guessing whatever is squeaking is lubricated by the rain, but i cant think of what it is. if ne1 has any experience or suggestions on how to fix this they would be much appreciated. thanks.

spray the whole coilver assembly with some lubricant
