I found the pdf for the 06 model on replacing the upper ball joint. It says that you have to remove the shock absorber. also you have to remove the stabilizer bar link. I found a you tube video of someone doing it,drastically different. What they did was jack up the car having the tire in a unsprung condition. Then they separated the upper ball joint from the spindle. Then they went under the hood and remove the two nuts on each side of the shock tower. They then removed the bolts passing them through the spring surrounding the shock. Thanks.
