my wife owns a 2004 outlander that has rear end squeekage. ive tried to remove those accessable bolts to possibly lube or replace them to no avail. ive used wd40,blaster spray, pounded ,used a ball joint press but no avail. i tried spraying undercoating to help supress the vibrations but that didnt help either. idid get 1 shock bolt out, greased and back. that helped but not enough. how can I get these stuck sobs out?
