To "unload" the bars there is a bolt in the bottom of the lower control arm in the center...... just take that bolt out and that will unload them that also adjust the ride height so with the car on the ground take a mesurment from the body to the ground so you can put it back to the same height if you want
After taking the bolt out there is a clip inside the rear mount take that out and the bar will come out to the rear........ mark the bar so you can put it back in like it came out
Some times they need alittle help to get them to move you can put a pair of vice grips on and tap with a hammer be careful not to scar up the bar

Hope this helps
