There is a good chance your torsion bars wont want to come out of the keys. Mine sure diddnt want to move. Since you have hoist access, its possible to drop the lower control arms, bars, and cross member all in one piece. Thats the way I ended up doing it.
If your keys fight you, Id quickly abort mission and just drop the entire unit. Save a bunch of time and a headache.
A pair heavy duty c-clamps make short work of rebuilding the spring packs. Make sure you got access to some.
And Id also suggest thoroughly inspecting all your front end components before the tear down so you know what needs replaced. Easier to do it while its all apart. Also a good time to replace those upper control arm cam bolts. Whoever does your alignment will be enormously grateful.
