How to replace sway bar?

Is it the sway bar or the end links that are bad? Sway bars very seldom fail as they are a chunk of steel tubing. The end links and bushings though fail all the time. I ask because replacing the bar on that car requires you to drop the rear of the subframe to get the bar out and a replacement in. To do that you really need a lift so you can get under the vehicle and move the components that you would normally place stands under if you were working on it in the average garage.
However if that is your intent you need the get the vehicle high enough that you can safely get under it, then remove the front tires, next disconnect the lower end of each stabilizer end link from the bar. Next use a tie strap to hold the steering rack while you remove the two bolts that secure it to the subframe. Next remove the two rear subframe bolts, now you can remove the bolts that hold the sway bar to the subframe. Reverse the process to install the new one. I would replace the bushings and mounts as well as both end links ass a set. The torque specs on on the attached images. You will need to use new bolts for the steering gear and the subframe as they are coated with a special thread adhesive.
