I installed some Steeda uppers and some Granatelli weight jacker lowers and i notice a popping noise, sometimes when the suspension changes (i.e. Turns or bumps) a friend of mine said his car did the same til he had his lower control arms welded to his axle. I dont want to do this, bc i might deciede one day to change my arms out and dont want to mess with something being welding on.
