You'll want to have as much of the suspension installed as possible while still being able to check for resistance/binding. So, torsion bars in, UCA's, spindles, LCA's installed. You'll need to remove the torsion bar adjusters so you can cycle the LCA up and down by hand. You'll also need the shocks out, and if you have a front sway bar you will want that disconnected as well. Then cycle the suspension up and down, from bump stop to bump stop, and check for binding.
