This bolt is a bit of a pain to line up correctly and its very easy to damage the lower control arm ball joint/bushing when re-installing so its probably best not to remove if you don't have to.

When re-tightening bolt #2.. Before starting the install measure from the center of the hub to fender at normal ride height and then mimic this measurement using a hydraulic jack to compress the suspension when tightening to avoid any undue stress on the bushing.
I tried this method of not removing the bolt, I could not get it to work. I even broke out a small jack and jacked the suspension down to try to get the spring out, no go.

In the end I removed the bolt. 1 side took me 5 minutes to get the bolt back in. The other side took an hour!!!! That bolt is a huge pain, very easy to damage the ball joint.

The front is a breeze.
