hello i had jus changed my suspension from stock to bilsteinhd/swift springs combo and even before i changed the suspension i had got this rubbing or squeekin noise over every bump and now even with the new set up i still have it and its even worst and the car doesnt feel to great especially when im switching lanes at higher speeds could these be a problem of the bushings are they worn out? how hard is it to replace them and is it expensive? the noise is driving me bonkers

 

anybody?
