To add a little to Vikki's excellent directions... When checking upper arm bushings and all balljoints, lift by lower arm to unload them. For the rest, support it by the frame.
Checking the body bushings can be done visually, or by carefully lifting the body (use wood on the seam) and observing movement between frame and body at the respective bushings.
The lower balljoints also should have a wear indicator where the grease (zerk) fitting is. If the circle of metal where the zerk screws in is flush or recessed from the rest of the stamping, the joint is worn out.
