Hi, I need to replace the front and rear sway bar bushings on my 99 GCS. Could someone please list the procedure for replacing the front and rear sway bar bushings. Anything I should look out for? I would like to know if you have to jack up the vehicle to relieve any pressure points before removing the sway bar. The rear sway bar looks fairly easy to take off without jacking up the rear end of vehicle. Thanks. Michael
