Well with the help of one jackstand and a 14mm socket things went off without a hitch. The front took about 20minutes. The rear bushings that were sent with the kit were a 17mm which for my T4R does not fit. It's too small and come to find out after removal of the rear swaybar, there is a 21 stamped on the stock bushing. I called Energy Suspension and they swear by the 17 but I don't know what 4Runner they were test fitting when they made the mold.
So far, I have not noticed a huge difference just because I don't have both front and rear done so it's still a bit squishy. If you know where I can find a 21mm poly bushing let me know.
Here are a few photos for your viewing pleasure.
