That's probably going to be your personal preference in what method that you choose to use.
I have done it both ways.
I prefer to press the shaft into the bushing first, then press those parts into the LCA.
You will need to press with a long piece of pipe the outer diameter of the bushing shell.
If you decide to press in the bushing first, then the shaft, you need to brace the back end of the shell with a 9/16 deep socket, or similar tool, to keep the bushing shell in place, when pressing.
I think you can use your noggin, and figure everything out.
