Ok, so I just switched out my stock springs for Skunk2 springs, and kept the stock struts on... but theres now a noise coming from the rear passenger side. I only hear the noise when i hit a bump in the road, and it sounds like the spring is loose and is popping in and out of place or something... but when i get under the car, nothing seems loose. Other than that, the car drives and rides fine.

any idea what this could be?

Thank you in advance for any help
