you need air tools and a spring compressor.

you dont say what your are doing but i had my front strut mounts changed for for 15 a side at the local front end shop, i removed them took them in to them and brought the new mounts with me, 30 bucks and its done, no hassles and im still safe. a spring compressor can kill you or f you up petty bad if it lets go on you, just saying, its hazard.
