How can I level?

[Aruba1]

How in the world did you guys fit this shocks under that truck? I have the truck fully jacked under the a-arm and the a-arm needs another 1 inch to compress so I can install the ball joint nut. It ain't happening, lol. Am I suppose to use some spring compression, it doesn't look like there is enough space.

Another thing is that I can is use my back hoe to just put some weight on the wheel axle (or whatever its called) so it will compress enough to install the bolt.
