Thats what i had did when i did it. I jacked up the opposite side and let the other side drop down as far as it could go. Didnt think to loosen the track bar til i had the one coil out. Im about to take the ones out of my 2007 because I dont know if the previous owner did it right or what he used. All I know is the front sits higher than the rear and isnt close to level.
