increase in noise. Later I installed ES bushings and the ride became very rough. Also, my stock diff which never made any noise before hand was now whinning very load anytime I wasn't accelerating. Very annoying! I now have a complete used rear subframe, control arms and hubs with stock bushings. I plan on switching out just the subframe first to see if the noise and ride improve. I suspect the noise will go away but I'm not sure if the ride will improve until I switch out all ES bushings.
