nah u dnt have to buy any compressor or even remove calipers either
u just need some stands and a jack
jack up ur car, take the wheel off and the old shock off too
put some stands in the chassis and lower ur jack and let the axle come down till u can get the spring off
if it happen like mine u prob have to put your jack in top of the radius arm to jack down the axle bit lower till u get enough space for the spring to get in
