Be sure to do several cycles of soaking the nuts in PB blaster before attempting to remove the nuts off the endlinks. My first attempt at taking the bar off resulted in several bent allen wrenches, but after more research I found that you need to put a open ended wrench on the back to keep the whole bolt from spinning.
This is where you want to use the open ended wrench and this picture helped me visualize what needed to be done.
Seeing as I did this by myself, I figured I could get a mechanical advantage by using a jack to push up (counterclockwise) on a box end wrench on the nut. At the same time I positioned the open ended wrench on the bolt such that it ran into the rear cross member. Next I repositioned the box end wrench and jacked up on it slowly breaking the nut free all while the open ended wrench kept the bolt from spinning.
After figuring this out, the install was pretty straightforward (minus me putting it in backwards at first
)
Hope this helps someone.
