Since I've had the car there is a creak I hear on the left side (passenger) when going over bumps. I went to remove the wheel and as I jacked up the car and the coil expanded I could hear it clearly. If I held a metal bar to me ear and placed the other end on the spring it was very evident.. I've lubricated everything I can see that moves with silicone spray just to eleviate other areas.

Question is how can I stop the creak on the damper / spring coil over without replacing as it's behaving fine?

Thanks
