So i have the Mopar coil overs on my car right now, and ive noticed that the front right seems a lil spungy when i hit bumps, and i hear an occasional knocking coming from it

. i was fixin to switch my friend my coil overs for his stock struts + lowering springs, because i simply didnt wana deal with the problem & face the fact that i have like... $1400 coil overs that im switching for basically $200 springs...
someone told me i could get the coil overs 're-built' is that true? if so what kind of shop would do that?!
please help me out here!!!!!!!
