just completed rear diff and sub frame bushings, lateral arms and trailing link bushings install and offer the following advice and tips:
always use stands after jacking your car.
a floor jack with block of wood can be used to push against a wrench to loosen some very tight nuts.
As a last resort cut thru bolts with a metal bladed saber saw.
coat all bolts entire length with anti seize and use lots of silicon grease on all metal to urethane surfaces.
lateral links went in with only cutting one bolt. rear trailing arms came off with cutting one bolt.
trailing arm bushings rear came out very easily. Drill 5-6 holes in rubber, then c clamp (use rotor surface with a block of wood) and push out. I replaced with 2 piece bushings, e-a-s-y. The front bushing is a mofo. Drilled, cut and pushed out. Then burned remainder. After cleaning (emery cloth and file) found out new front bushing was wrong size. Ordered new trailing arms with pillow ball front bushing already installed, Megans $230 shipped. Recommend that route to begin with or 2 piece fronts if they exist.
