When I swapped my daughters 2015 Grand Cherokee from air suspension to springs on all 4 corners I used this autozone rental to do the rears:

It took a lot of messing with the alignment of the tool on the springs, but eventually it worked. It’s rare for me to think this, but halfway thru the job I wished I had taken it to my Indy.
