urethane bushings

[69gmcc10]

I have a very annoying squeak coming from my lower control arm bushings so I have purchased a set of urethane bushings to replace the broke down rubber ones.

Has anyone done this? I cant seem to find any youtube videos on how to replace them on a Silverado specifically. Can I replace them without removing the arm from the truck?

My thought was to place the front end on jack stands, loosen the torsion bar all the way, undo the sway bar and shock, remove the 2 bolts that connect the arm to the frame and let the arm fall low enough to access the bushings and swap them out. Does this seem like it will work? Am I missing anything? suggestions?
