Hey, i posted this once b4, but no one wrote anything. so here i am here again asking for help. after i changed my spring to some coilovers, it started to make a rattle sound from the back wheel (passenger side) it sounds like something is loose... so i dont know can anyone give me a hint? i checked everything, i took off the spring and shock reinstalled it but still makes that sound. does anyone know or having the same problem? let me know ty!

 

Make sure everything is torqued. And if its a sleeve coil-over design make sure you use the set screws and rubber rings to properly align it to the shock/strut.

Make sure you double and triple check everything. And if its too low you could be dragging something or causing stress or abnormal wear to one of the parts.

 

i took off everything and double checked them. my car was only maybe 1.5 inch lowered. and i have all the rubber rings in place...=/ i had 3 of my friends checking for me, none of them knew wut's the problem. but thanks for helping much appreciated

 

abs lines? maybe the rear rotor dust cover?
